How to paint over smoke damaged walls

This article is intended to help painters and homeowners understand the proper painting process for covering smoke damage. The type of smoke determines the type of contaminants concentrated in the area and may require different cleaning techniques.

Although your interior walls or trim may have been exposed to smoke ranging from cigarettes to a wood burning fireplace, the paint prep steps to eliminate odors and achieve proper paint adhesion are relatively the same.

We cover the process, best materials and practices to ensure a smooth and safe paint job. We also explain how to assess low levels of smoke residues such as nicotine and tar, and when to consider a mitigation team for further assessment.

Proper paint preparation for smoke damage

Painting smoke damaged walls and trim takes a little knowledge. You don’t want to make a mess by skipping the necessary steps or applying the wrong paint materials.

If you ultimately decide to replace things, the decision should be based on the amount of damage. Additional damage from omitting proper painting preparation should be avoided.

Just repainting soot or yellowed trim due to smoke causes more problems and potentially ruins painted surfaces. Whether you want to freshen up the area by eliminating odors, removing smoke stains, or simply creating a new look, painting with traditional household paint won’t work.

Additional steps are required to eliminate odors, prevent stain penetration and ensure proper paint adhesion.

Does smoke damage require a mitigation company?

Smoke accumulation in a home can persist for a number of reasons. If you are using a wood burning fireplace, smoke may form around your mantel.

If you light candles or smoke in a house for a long period of time, smoke residue will be noticeable on the ceilings and settle on walls and crown molding. It’s also important to understand that there are different forms of smoke damage.

Damage caused by excessive cigarette or cigar smoke, for example, is considered minor compared to an apartment fire. If the damage meets the criteria of “major” or “natural,” or if an insurance company is involved, you should contact your local fire damage restoration company.

These situations are considered serious and we respect the real issues surrounding the Pacific Northwest wildfires and all other areas. This article is not intended to deal with significant fires or natural disasters. Rather, we handle proper paint preparations containing light to subtle smoke contaminants that can be managed by professional painters or homeowners when certain basic principles are applied.

Painting over cigarette smoke and smoke residue

While painting over cigarette smoke adds extra steps, the process may not be as complex as you think. For painters with basic painting experience, the principles are easy to understand.

For those inexperienced, the additional paint prep steps may still be doable yourself – if not, you’ll at least understand the general process. However, there are several smoke accumulation scenarios that we may have overlooked and not addressed. If your smoke damage doesn’t square with the topic of this article, it’s important to get a professional opinion.

From light pollution to serious smoke damage, here are a few tips and important steps to approach the process.

How to paint smoked damaged walls and paneling

Step 1: Identify the amount of nicotine, tar and soot. First you need to identify the problem and how far the problem is spreading and persisting. How much settlement is on the surface?

The general rule is, if you can see it, there is a significant amount of soot, nicotine, or tar on the surface. How far does it stretch? Not all impurities are visible. So test areas further from the source, or visibly distinctive areas, to determine how much additional color preparation is needed.

Use a white cloth and acetone to test unidentified areas. Clean or wipe a surface approximately 4 square feet wide. If there is black, brown, or gray residue on the rag, that area has also accumulated and requires additional color prep.

Step 2: The second step is to set up and contain dust and contaminants. Set up a perimeter of lightweight plastic with containment poles. Don’t forget to cover the floor with drop cloths. You may also want to wear a color suit to keep yourself clean.

Step 3: Along with step one, this is one of the most critical and frequently asked phases of the process. How do you clean smoke damage?

For extreme deposits, a combination of wiping and sanding is required to remove the contamination. A professional and experienced interior painter with a wealth of knowledge may be required to ensure this part of the process is not skipped or overdone.

Step 4: Priming the surface with a quality primer is imperative. Some contractors recommend an oil-based primer. But in our experience, oil-based foundations give off a strong odor and are slow drying. If dried interior paint coatings are wet for a long period of time, they will degrade or peel off the surface. Slow drying times slow down the process and can have a negative impact on the primer.

Shellac is the best primer for smoke damage. It will alleviate any problems that a traditional oil primer causes. Shellac dries quickly, blocks odors, sticks to various surfaces, and the odor quickly dissipates. We recommend applying two coats of Bin Shellac Primer to all light to moderate smoke damaged surfaces.

Step 5: After waiting 24 hours, check for continued bleeding or leakage. If there are no visible signs of bleed through, you can begin the usual interior paint preparations. These preparations include drywall repairs, caulking of paneling, wall bezels, and puttying of nail holes.

smoke damage color

After the smoke problem is solved, you should focus on indoor air quality. Several excellent interior paints look good and adhere well once surfaces are cleaned and primed. But with today’s technological advances, some colors will improve air quality.

Carpets and blankets block most odors and trap dust and dirt, and smoke is no exception. So until these areas are treated, the odor will linger. We recommend removing carpets and painting ceilings before applying topcoats to paneling or walls.

For the best indoor air quality and wall coverage solutions, we recommend Sherwin-Williams Harmony. Harmony removes unwanted VOCs and formaldehyde. It improves air quality even months after the paint has dried. That’s pretty impressive!

The use of a metal material in the creation of a new product or structure brings a large number of advantages: high strength, ductility, toughness, ability to withstand the environments, and many others. One of the most important advantages of metal is its ability to withstand heat. However, all metals can be heated to the point of decomposition. Overheating and burning are common phenomena that can happen to metals at high temperatures.

What is the difference between overheating and burning a metal?

To understand the difference, one must first gain an understanding of overheating and combustion, which we explain below.

What is overheating?

Overheating of a metal occurs when its previous properties are compromised by elevated temperatures. Perhaps the most worrying effect of overheating is on the mechanical properties of a metal. Depending on the situation, the change in mechanical properties due to overheating can lead to property damage, environmental damage, injuries and death.

Overheating can lead to a variety of changes in the mechanical properties of a metal. The nature of the change is highly dependent on the overheating of the metal. A hardened steel that is subjected to overheating can show a significant loss of hardness and strength. Because overheating changes the microstructure of steel. Overheating can also lead to changes in the mechanical properties of other metals. Precipitation hardened materials such as 6061-T6 aluminum can undergo a process known as overaging when overheated. The precipitates in the aluminum alloy can grow from overheating, which in turn causes them to be too large to block dislocations. Without the precipitates in a precipitation hardening metal to block dislocations, the strength is greatly reduced.

Overheating can also change other properties of a metal. Aesthetics can be negatively affected. Many metals change color when overheated. Metal coatings can also be damaged or destroyed. Electrical properties are typically altered when metals are overheated, although they usually return to normal once the metal returns to normal temperatures. The dimensions of a metal can also be changed by localized overheating, which leads to deformation.

Many of the effects of overheating can be mitigated or eliminated entirely with post-heat treatment. For example, a precipitation-hardened aluminum alloy whose strength has been severely reduced as a result of overheating can be restored by an additional heat treatment that changes the size of its precipitates to block dislocations. The mechanical properties of a hardened steel that has been weakened by overheating can be restored by heating and quenching or by some other method.

what is burning

Burning occurs when a metal becomes overheated to the point where it is beyond repair. While many instances of the negative effects of overheating can be fully or at least partially reversed, the effects of burns are much more permanent. This often results in metal structures or components that have to be scrapped.

There are two common degradation processes that can occur when a metal is burned. A common phenomenon that occurs is intergranular oxidation. Intergranular oxidation is corrosion that occurs at the grain boundaries of a metal. This often occurs when oxygen no longer binds to corrosion-resistant elements and instead binds to a more easily corroded element. An example of this could be stainless steel that has been depleted of chromium because it has been burned. The result of firing is that iron oxide is formed instead of chromium oxide and the stainless steel begins to degrade. The other event that can happen when a metal is burned is that it begins to melt. Incipient melting occurs when some of the alloying elements at the grain boundaries of a metal alloy melt, but not all of the elements. This can lead to porosity and other discontinuities that cannot be repaired by further heat treatment.

How to bring your painted walls back to perfection after smoke damage

If your walls have been damaged by smoke, you may be able to clean them to remove soot and tar residue. However, this does not always work. Sometimes the residue sticks to the wall so tightly that the paint comes off when you try to clean it. However, it is worth knowing how to remove smoke damage from painted walls. When a coat of paint is needed, cleaning a wall is the first step in making it look new again.

In this article, you’ll learn how to attempt a cleanse and what to do if your efforts aren’t working properly. Prepare for the worst, hope for the best, and restore your painted walls to perfection.

Smoke damage is like other stains

Even with the toughest of stains, there’s a good chance you can clean a wall so well you’ll forget where the stain was. There’s even a method to remove Sharpie from walls. Smoke damage is different from other stains.

Smoke is a mixture of tar and soot. When it’s stuck to a wall, it’s like a whole new coat of paint. It’s possible that your efforts aren’t cleaning the wall the way you hoped. However, if this is the case, at least your wall is primed for painting.

How to clean a smoke damaged wall

1. Clean the wall with a dry chemical sponge

The first thing to do is remove as much of the loose soot as possible. You do this with a dry chemical sponge. Never use a wet sponge. If you do this you will only spread the soot and make a bad smoke stain ten times worse.

When removing smoke damage from walls, make sure you open a window or door to ventilate the room and wear a dust mask to prevent soot inhalation.

2. Now clean with a detergent

After removing all loose parts you can now wash the walls with a strong detergent (Trisodium Phosphate (TSP) is one of the best). Mix one tablespoon of TSP in one gallon of warm water and apply to walls with a clean sponge. Wipe sponge, rub gently.

TSP can irritate eyes and skin, so it’s important to wear safety glasses and gloves. Also, protect floors, carpets, and furnishings by covering them with plastic.

3. After cleaning, spray your walls to fight the smoke smell

The smell of smoke lingers in a home and you will want to get rid of it. No need to use expensive cleaning products – smoke odor removal can only be done with vinegar or baking soda. In our article, 5 Easy Ways to Remove the Smell of Smoke from Your Home, we detail simple ways to get rid of the unpleasant, stale smell of smoke.

What if the smoke damage is still visible?

The smoke damage may not have been completely removed after cleaning. In this case, you will have to repaint the wall. Luckily, you’ve already done the hardest part of the job: cleaning and preparing the surface. Now there are only two steps left to make your walls look like new again:

1. Prime walls

If you try to paint directly over a remaining stain, the stain will eventually come through. You need to prime the walls first.

We recommend using a pigmented shellac primer, which will cover the stain and prevent odor leaching. This part of the process can be messy, so leave those protective covers in place. The primer is also very smelly, so once again make sure you’re working in a well-ventilated area.

2. Paint

Once the primer has dried, use your choice of paint – matte or vinyl – and paint like you would any other wall. You may need two coats to finish the job perfectly.

That’s it! Your wall is now as good as new (provided of course you’ve also taken care of fixing any holes, ridges or stains that need filling).

Step 1

Wipe the walls with a damp sponge to remove particles loosely attached to the wall. You can soak the sponge in a mild detergent or a weak dilution of TSP, but do not allow drywall surfaces to become soaked with water as this can damage the sheetrock. Unless the traces of soot are relatively minor and new, you will find it difficult to completely remove the stains as they have become embedded in the existing paint layer.

The devastation of a fire can wreak havoc on a building and requires significant work to restore. Fire damage restoration is designed to undo the destruction of a fire and restore structures to their former condition – and applying coatings to walls and surfaces is a crucial part of this process.

Smoke damage sealers are a special type of coating that adhere to damaged surfaces, blocking stains and preventing the noxious odors caused by smoke after a fire and protecting a building from the aftermath of the fire.

You may not realize how important sealers are to a successful fire remediation, but post-fire smoke sealant is an essential part of preparing the site for reuse, covering damage after cleaning and contaminant removal, and ensuring deodorization and maintenance Avoid additional damage. From choosing the right primer to distinguishing between sealers and painting over fire damaged walls, here’s everything you need to know about smoke smell sealers.

When to use a sealer

How useful can sealants be and when is the right time for fire rescuers to use them?

As more restoration companies have emerged over the years to repair damage from fire and other disasters, smoke sealers are often used in a variety of ways.

Smoke seals may only be used after all cleaning and contamination removals have been completed to the satisfaction of all parties involved. They are not intended to cover up poor restoration work. Where a sealer should be applied – and whether a sealer should be applied at all – depends on the individual scenario, with factors such as the type of fire that has occurred and the extent of the damage influencing the choice.

In 2016, fire departments across America responded to approximately 1,342,000 fires, 74 percent of which were building fires. With residential fires occurring on average every 90 seconds and non-residential fires every 66 seconds, the magnitude of national fire damage is significant and the need for recovery critical.

Since fires start for different reasons, the type of chemical and physical damage differs from structure to structure:

Cooking appliances cause about 47 percent of home fires

Heaters account for 15 percent

Electronic devices make up 9 percent

Tobacco products make up 5 percent

In addition to the presence of chemicals responsible for starting the fire, the fire itself produces a variety of toxins that contaminate the building – these can also affect the choice of when and whether to use a sealant.

Why use smoke sealant at all?

The heat, flames and uncontrolled combustion of fires result in the formation of a mixture of harmful chemicals, including gases, liquids, aerosols and partially oxidized particles, some of which adhere to surfaces and attack materials. Even after the fire is extinguished, toxic odors and fugitive emissions can continue to damage the structure and make the area dangerous.

Combined with effective cleaning and contamination removal techniques, sealers can be an effective means of preventing smoke odors or stains from reappearing and act as a primer by adhering to difficult surfaces to allow a final coat of paint to be applied.

Remember that sealers are not in themselves a cleaning product and should never be used to cover up odors or contaminants that should be treated and removed. Sealers serve to bond surfaces, seal pores, and prevent the recurrence of odors, stains, and additional damage. They should only be used after proper, thorough cleaning and removal of contaminants.

Sealer vs Encapsulant: What’s the Difference?

Even in the professional restoration industry, the terms “sealant” and “potting compound” are sometimes used interchangeably, but they shouldn’t be. The two types of coatings have very different purposes and confusing their uses could cause problems.

What is the difference? Encapsulation describes the process of enclosing or suppressing something, so it makes sense as a term for wall coatings and primers. Technically, sealants encapsulate porous surfaces and prevent odor and damage from returning. Investment compounds perform a similar function, being applied to walls to permanently control and reduce the presence of asbestos and lead paint in older buildings.

While these two types of coatings appear superficially to serve the same purpose of preventing further damage from odor and chemical release, they are fundamentally different in terms of process engineering, which creates the potential for confusion.

Encapsulation: A coating used to control exposure to underlying materials or contaminants. This term is often used when dealing with exposure to asbestos or lead-based paint.

A coating used to control exposure to underlying materials or contaminants. This term is often used when dealing with exposure to asbestos or lead-based paint. Sealer: A coating applied after all contaminants have been removed and the surfaces have been thoroughly cleaned to prevent damage such as stains or odors from recurring.

Sealers can only be applied to surfaces after thorough cleaning and removal of contaminants and will prevent damage from recurring. Encapsulants, on the other hand, are placed directly over the unwanted substance, covering it rather than removing it.

During restoration, removal of contaminants is always done prior to coating with a sealer, therefore potting compounds and sealers should not be confused or used interchangeably in the fire restoration industry.

Considerations when choosing a sealer for fire damage restoration

Now that you are familiar with the basic purpose and uses of sealers, how do you determine the best primer for smoke damage?

Each type of sealer has its own specific characteristics and limitations, so it’s important to choose the type that best suits your needs based on the individual project. Here are some questions to consider when evaluating the features, functions and benefits of a restoration sealant.

Does it stick?

The first step in evaluating the benefits of a particular sealer is to observe whether it will adequately adhere to the surface to be coated. If the sealer does not adhere well, it is not particularly suitable for the surface and is not a good choice to aid in the restoration.

Will it suppress lingering fire-related odors?

Half of a sealer’s job is preventing the return of unpleasant or noxious odors from smoke and fire-related chemicals. When choosing the right sealer, make sure it is effective at suppressing existing odors and preventing those odors from returning through the pores of the surface. If not, the coating is just for show – and that’s not useful for your purpose.

Can it reliably seal stains and residue?

The other half of a sealer’s functionality is to block the spread of stains and residue. The aim is to keep the decontaminated surface clean and attractive and to restore it to its former condition, so the risk of bleeding smoke stains should be reduced as much as possible. An effective seal must prevent unsightly and unwanted stains from spreading if at all possible.

Can water vapor breathe?

If the structure you are restoring has internal moisture of any kind due to its function, make sure the seal you choose allows some release of water vapor. Using an incompatible coating in an area where moisture will collect can cause other problems in your restoration work in the future, including water damage and wall warping.

Will using the sealer ease cleaning complications?

During your restoration process, consider where the use of sealant can be applied. If you were able to clean, decontaminate and deodorize without many remaining problems, sealing is one of the final steps to ensure recovery, so make sure it simplifies the process and doesn’t add unnecessary steps.

Sealer should be appropriate for the environment to streamline the process of restoring the structure to its pre-damage condition. If adding the sealer makes cleaning difficult, it may not be the right kind or it may not be needed at all.

Is the sealing sustainable for the future?

Finally, sealing smoke damage is a step designed to ensure the sustainability of the restored space. Make sure you choose a coating that will continue to serve its purpose and hold up over time, protect the structure from stains, odors and chemicals well into the future, and give the building a long second life.

Types of fire and smoke damage waterproofing

Now that you know the critical considerations when choosing a well-suited sealing device, you should familiarize yourself with the different categories of sealing devices along with their characteristics, capabilities and limitations.

Selecting the appropriate sealant for application in a specific task must balance capabilities and limitations with the project’s most pressing needs, and consider criteria based on preferences such as price, performance, personal protective equipment (PPE) requirements, and sustainability based.

Available sealants are primarily differentiated by chemical formulation and fall into four categories:

On a water basis

shellac

alkyd

fixer

Water based fire and smoke damage sealant

This type of sealer consists of acrylic polymer systems sometimes mixed with specialty resins in a water-based carrier. Some water-based solutions – like RECON Smoke Sealer – are specifically designed for fire damage restoration and tailored to your needs. Professionals typically use this category of sealer to seal stains, and it is available through professional restoration distribution centers at a similar or lower cost than shellac.

Water-based sealers are useful because they have the ability to seal in smoke odor while still offering moisture vapor transmission, meaning they don’t develop layers of condensation. They are also highly flexible and have minimal odor and low volatile organic content (VOC). Unlike other types of sealants, this category is relatively harmless to environments or occupants with high chemical sensitivity and does not require special treatment for disposal of excess waste. There are also no additional PPE requirements.

Water-based sealer is versatile and available in a variety of tints, colors and finishes from matte to gloss. It is also extremely safe and poses no flammability and combustibility hazards.

For all their excellent qualities, water-based sealers have some limitations, including:

A greater preparation time requirement

A softness for your cured film

A variability in drying time

Variable stain protection performance – while some sealers are effective with just one coat, others may require two or more applications

They are also sensitive to material types, meaning solvent-rich topcoats can damage them, and they can be repelled by high levels of silicone in surfaces.

You can’t use this type of sealer in surface and air temperatures below 45 degrees Fahrenheit, and not all water-based solutions apply equally, meaning some require brushes or rollers, while others are available as airless sprays.

Shellac fire and smoke damage sealers

Consisting primarily of processed lacquer resin secreted by insects native to Indonesia and India, this sealant is made by suspension in alcohol. Historically, shellac was the most commonly used sealant in fire damage restoration due to its primary ability to control burnt odor. In fact, it has a decades-long history of successfully sealing smoke odors in treated surfaces. This sealer is available at almost all paint centers and paint retail stores and is the most expensive type.

Shellac possesses several useful properties, including its ability to be cured and applied at much lower temperatures than other sealer formulations – down to 10 degrees Fahrenheit. It can also:

Stick to hard or difficult surface conditions

Accept almost any type of top coat as a primer

Dry in under 30 minutes for maximum recovery efficiency

Once dry, the cured surface is extra hard compared to other sealers and is ideal for stopping stains.

In addition to its laudable properties, shellac has some limitations, so make sure its properties match your project.

This special seal is moisture vapor impermeable, meaning it can trap moisture and create a barrier to condensation. It can also become brittle when subjected to direct impact, making it an unsuitable choice for outdoor use. Remember that shellac requires special attention when cleaning with denatured alcohol and exposing its vapors to ignition can be dangerous.

Shellac also requires special treatment – in the form of solvent recycling – for the disposal of excess material. While it prevents smoke odours, it also leaves an unpleasant paint smell for up to a week which may require carbon filtration to eliminate completely. It also requires PPE for the application, such as B. Respirators to make it safe to inhale and you should be aware of regulations regarding maximum VOC levels which may make it unavailable in certain areas.

Alkyd based fire and smoke damage sealant

Alkyd primers are oil based and are typically more commonly used to seal water stains. None are technically intended for fire remediation, but they can serve these types of applications. Waterborne alkyds and other hybrid coatings are emerging within this category. Alkyds are typically available at hardware and retail paint stores and are among the most inexpensive sealer formulations.

Alkyds have a number of positive properties including their tolerance of difficult or imperfect surface conditions, excellent stain blocking abilities and fast drying abilities. This sealer is also easy to sand and, once thoroughly cured, will accept almost any oil or water based top coat as a primer.

Limitations of alkyd based sealers include:

Uncertain permeability or lack of permeability

Expected VOC Restrictions

PPE Requirements

flammability and combustibility

Persistent smell

Special requirements for waste treatment

Alkyds also require extensive mixing before application, and they involve a lengthy cleaning process with mineral spirits, which can increase exposure to solvents and cost more labor and productivity.

Fixative fire and smoke damage seals

Fixative sealant formulations are particularly low in solids, helping residual particles adhere to surfaces and prevent them from contaminating the air and becoming respirable. This can be useful for isolating and eliminating toxins to stop further circulation after fire damage cleanup, but is not particularly useful for preventing further surface damage or preventing smoke stain penetration as it does not form a tactile film.

The Do’s and Don’ts of Smoke Damage Sealers

With the details of sealant uses, categories and considerations, you are almost ready to properly incorporate them into your fire damage restoration projects. Just make sure you follow these crucial do’s and don’ts with any smoke damage sealing procedure.

Do:

Consider the needs of each project. This can include environment, exposure, extent of damage and future function of the structure. Being careless in choosing your sealer can prevent the site from reaching its full recovery potential in the future and can lead to problems later. Use a product intended for fire or smoke damage. Take extra care to select a sealer that you know will counteract smoke damage and odors, especially in a structure with extensive damage or in a sensitive environment. As the categories above show, some sealers – like alkyds – are meant for other purposes, so handle them with care and always choose the product that’s specifically designed to do the right job. Pay attention to the preparation of your seal. Some sealants require extensive mixing or safety preparation before use, and failure to meet these requirements or misuse can result in damage or a hazardous condition. Before you choose your sealant, find out exactly how it is prepared and used.

Carry out proper cleaning and waste disposal. Some sealants are safer while others are flammable, hazardous, high in VOCs and specific to PPE and toxic waste requirements. To ensure health, safety and effectiveness, make sure you are familiar with the proper handling and disposal of any materials you use.

Do not:

Use seals to cover up bad work. It is imperative that a structure be fully cleaned, deodorized and decontaminated before applying a smoke damage sealant. Sealers cannot cover up remaining contamination or incomplete cleaning work – they can only serve to prevent additional stain spread and odor escape. Just use any paint primer. Specially designed for damage treatment, sealers are the only coatings you can use to cover smoke damage and block smoke odors. Using an ordinary paint primer on smoke and fire damaged surfaces will create an incompatible situation and will only result in further damage to the surface.

Use sealers alternately. Each seal has unique traits, properties, and limitations that make it better suited to specific environments and situations. Never assume that two different types of sealant will do the same thing or that you don’t need to research their use in relation to the specific project. Choose the most suitable seal and do not mix types.

Each seal has unique traits, properties, and limitations that make it better suited to specific environments and situations. Never assume that two different types of sealant will do the same thing or that you don’t need to research their use in relation to the specific project. Choose the most suitable seal and do not mix types. Be carefree when using and cleaning. Just as each sealer has different properties, the procedures for preparing, applying and disposing of the coating vary depending on the type of formulation. Pay close attention to the handling instructions for your particular sealer to ensure the coating is effective, the process is safe, and dry cleaning is performed properly.

Always use fireproofing with care and consideration and wish you the best of luck in your fire damage restoration projects.

Can I paint over smoke damage?

Catastrophic events such as fires can cause smoke damage. To restore your property to its natural state, you might consider painting over the affected areas.

Before you do, you should be aware that smoke damage to your home or business is more than just smelling and looking bad. It is also uncomfortable and harmful to your health. If you don’t take care of it quickly, your walls can get permanent stains.

So what should you do?

It is best to remove the soot and quickly paint over the smoke damage. If you’re wondering how to paint over smoke damage, check out our step-by-step guide below.

1. Dry cleaning

Soot removal from a wall is necessary before painting begins. This process is called dry cleaning and is essential to neutralize the damage caused by smoke and fire.

Before you start dry cleaning, you need to remove all loose dirt, grime, and debris from the walls. This will give you a smooth painting surface.

Then you need a dry cleaning sponge. These are special sponges that you can buy at hardware stores that are made to remove soot. Use the sponge to gently wipe down all smoke damaged walls and ceilings. You may need to change your sponge if it becomes too saturated with soot, so have several backups on hand.

Once you’ve cleaned all the walls and ceilings with the dry sponge, you can move on to the next step.

2. Wet cleaning

You will immediately see the difference in the cleanliness of the walls after the dry cleaning process. For this next step, you should wear protective clothing to avoid getting cleaning liquid on your personal clothing. A mask is also required to prevent inhalation of cleaning products.

Which cleaning agent should I use? We recommend phosphate-based full-cleaners in powder form. These are best for blocking stubborn stains so you can prime them.

Here are the steps for the wet cleaning process:

Mix the cleaning powder with water and apply the mixture to your walls and ceilings. Use the sponge and wipe away the smoke damage with long strokes. After you’ve cleaned all the smoke-damaged surfaces, use another sponge to rinse the walls and ceiling with clean water. Wait for it to dry completely.

3. Prime

You must also apply a primer to walls that are not smoky before painting. For smoke-damaged walls, before applying the primer, you need to make sure there are no stains left on the walls.

Double check that your walls are completely clean, then start priming. Priming the walls is easier than painting because while it should be perfectly level, it doesn’t have to be perfect. Just make sure you cover the spots and you’re good to go.

When priming, we recommend using two coats to ensure full coverage and stain blocking. You must allow the primer to dry for two hours before attempting to paint over it. Also, be sure to observe the following safety precautions:

Primers often have a very strong chemical smell, so make sure to keep your windows open to allow air to circulate.

You should also wear a mask during this step so you don’t inhale the fumes from the primer.

4. Paint

We’ve come to the final step in the process: painting! At this point you should not see any stains through the primer. If stains are still visible through the primer, you may be able to see them through the paint as well.

One of the decisions you need to make is whether to paint just the damaged area or the entire wall. Although it’s entirely up to you, we recommend painting the entire wall to avoid weird overlapping streaks.

Be sure to apply a few coats to ensure you get the color payoff you expect from your paint. When you’re done painting, you can redecorate your walls, hang photos, or whatever else you want to add to your solid walls!

Do I need to replace the drywall if there was a very small fire and the drywall didn’t burn? It has smoke stains. One portion reached 140 degrees F, according to firefighters, but it was a fairly contained dryer fire and smoke remained in the small laundry room. If I patch it (after testing all the wires) it would be temporary until I pay for the 1000 other things that just happened at my house this week (30 year old stove replaced. Same goes for the water heater and of course the washer and dryer)

oh patch needed where FD cut the wall to check spread where there wasn’t.

Step 1

Wipe the walls with a damp sponge to remove particles loosely attached to the wall. You can soak the sponge in a mild detergent or a weak dilution of TSP, but do not allow drywall surfaces to become soaked with water as this can damage the sheetrock. Unless the traces of soot are relatively minor and new, you will find it difficult to completely remove the stains as they have become embedded in the existing paint layer.

The devastation of a fire can wreak havoc on a building and requires significant work to restore. Fire damage restoration is designed to undo the destruction of a fire and restore structures to their former condition – and applying coatings to walls and surfaces is a crucial part of this process.

Smoke damage sealers are a special type of coating that adhere to damaged surfaces, blocking stains and preventing the noxious odors caused by smoke after a fire and protecting a building from the aftermath of the fire.

You may not realize how important sealers are to a successful fire remediation, but post-fire smoke sealant is an essential part of preparing the site for reuse, covering damage after cleaning and contaminant removal, and ensuring deodorization and maintenance Avoid additional damage. From choosing the right primer to distinguishing between sealers and painting over fire damaged walls, here’s everything you need to know about smoke smell sealers.

When to use a sealer

How useful can sealants be and when is the right time for fire rescuers to use them?

As more restoration companies have emerged over the years to repair damage from fire and other disasters, smoke sealers are often used in a variety of ways.

Smoke seals may only be used after all cleaning and contamination removals have been completed to the satisfaction of all parties involved. They are not intended to cover up poor restoration work. Where a sealer should be applied – and whether a sealer should be applied at all – depends on the individual scenario, with factors such as the type of fire that has occurred and the extent of the damage influencing the choice.

In 2016, fire departments across America responded to approximately 1,342,000 fires, 74 percent of which were building fires. With residential fires occurring on average every 90 seconds and non-residential fires every 66 seconds, the magnitude of national fire damage is significant and the need for recovery critical.

Since fires start for different reasons, the type of chemical and physical damage differs from structure to structure:

Cooking appliances cause about 47 percent of home fires

Heaters account for 15 percent

Electronic devices make up 9 percent

Tobacco products make up 5 percent

In addition to the presence of chemicals responsible for starting the fire, the fire itself produces a variety of toxins that contaminate the building – these can also affect the choice of when and whether to use a sealant.

Why use smoke sealant at all?

The heat, flames and uncontrolled combustion of fires result in the formation of a mixture of harmful chemicals, including gases, liquids, aerosols and partially oxidized particles, some of which adhere to surfaces and attack materials. Even after the fire is extinguished, toxic odors and fugitive emissions can continue to damage the structure and make the area dangerous.

Combined with effective cleaning and contamination removal techniques, sealers can be an effective means of preventing smoke odors or stains from reappearing and act as a primer by adhering to difficult surfaces to allow a final coat of paint to be applied.

Remember that sealers are not in themselves a cleaning product and should never be used to cover up odors or contaminants that should be treated and removed. Sealers serve to bond surfaces, seal pores, and prevent the recurrence of odors, stains, and additional damage. They should only be used after proper, thorough cleaning and removal of contaminants.

Sealer vs Encapsulant: What’s the Difference?

Even in the professional restoration industry, the terms “sealant” and “potting compound” are sometimes used interchangeably, but they shouldn’t be. The two types of coatings have very different purposes and confusing their uses could cause problems.

What is the difference? Encapsulation describes the process of enclosing or suppressing something, so it makes sense as a term for wall coatings and primers. Technically, sealants encapsulate porous surfaces and prevent odor and damage from returning. Investment compounds perform a similar function, being applied to walls to permanently control and reduce the presence of asbestos and lead paint in older buildings.

While these two types of coatings appear superficially to serve the same purpose of preventing further damage from odor and chemical release, they are fundamentally different in terms of process engineering, which creates the potential for confusion.

Encapsulation: A coating used to control exposure to underlying materials or contaminants. This term is often used when dealing with exposure to asbestos or lead-based paint.

A coating used to control exposure to underlying materials or contaminants. This term is often used when dealing with exposure to asbestos or lead-based paint. Sealer: A coating applied after all contaminants have been removed and the surfaces have been thoroughly cleaned to prevent damage such as stains or odors from recurring.

Sealers can only be applied to surfaces after thorough cleaning and removal of contaminants and will prevent damage from recurring. Encapsulants, on the other hand, are placed directly over the unwanted substance, covering it rather than removing it.

During restoration, removal of contaminants is always done prior to coating with a sealer, therefore potting compounds and sealers should not be confused or used interchangeably in the fire restoration industry.

Considerations when choosing a sealer for fire damage restoration

Now that you are familiar with the basic purpose and uses of sealers, how do you determine the best primer for smoke damage?

Each type of sealer has its own specific characteristics and limitations, so it’s important to choose the type that best suits your needs based on the individual project. Here are some questions to consider when evaluating the features, functions and benefits of a restoration sealant.

Does it stick?

The first step in evaluating the benefits of a particular sealer is to observe whether it will adequately adhere to the surface to be coated. If the sealer does not adhere well, it is not particularly suitable for the surface and is not a good choice to aid in the restoration.

Will it suppress lingering fire-related odors?

Half of a sealer’s job is preventing the return of unpleasant or noxious odors from smoke and fire-related chemicals. When choosing the right sealer, make sure it is effective at suppressing existing odors and preventing those odors from returning through the pores of the surface. If not, the coating is just for show – and that’s not useful for your purpose.

Can it reliably seal stains and residue?

The other half of a sealer’s functionality is to block the spread of stains and residue. The aim is to keep the decontaminated surface clean and attractive and to restore it to its former condition, so the risk of bleeding smoke stains should be reduced as much as possible. An effective seal must prevent unsightly and unwanted stains from spreading if at all possible.

Can water vapor breathe?

If the structure you are restoring has internal moisture of any kind due to its function, make sure the seal you choose allows some release of water vapor. Using an incompatible coating in an area where moisture will collect can cause other problems in your restoration work in the future, including water damage and wall warping.

Will using the sealer ease cleaning complications?

During your restoration process, consider where the use of sealant can be applied. If you were able to clean, decontaminate and deodorize without many remaining problems, sealing is one of the final steps to ensure recovery, so make sure it simplifies the process and doesn’t add unnecessary steps.

Sealer should be appropriate for the environment to streamline the process of restoring the structure to its pre-damage condition. If adding the sealer makes cleaning difficult, it may not be the right kind or it may not be needed at all.

Is the sealing sustainable for the future?

Finally, sealing smoke damage is a step designed to ensure the sustainability of the restored space. Make sure you choose a coating that will continue to serve its purpose and hold up over time, protect the structure from stains, odors and chemicals well into the future, and give the building a long second life.

Types of fire and smoke damage waterproofing

Now that you know the critical considerations when choosing a well-suited sealing device, you should familiarize yourself with the different categories of sealing devices along with their characteristics, capabilities and limitations.

Selecting the appropriate sealant for application in a specific task must balance capabilities and limitations with the project’s most pressing needs, and consider criteria based on preferences such as price, performance, personal protective equipment (PPE) requirements, and sustainability based.

Available sealants are primarily differentiated by chemical formulation and fall into four categories:

On a water basis

shellac

alkyd

fixer

Water based fire and smoke damage sealant

This type of sealer consists of acrylic polymer systems sometimes mixed with specialty resins in a water-based carrier. Some water-based solutions – like RECON Smoke Sealer – are specifically designed for fire damage restoration and tailored to your needs. Professionals typically use this category of sealer to seal stains, and it is available through professional restoration distribution centers at a similar or lower cost than shellac.

Water-based sealers are useful because they have the ability to seal in smoke odor while still offering moisture vapor transmission, meaning they don’t develop layers of condensation. They are also highly flexible and have minimal odor and low volatile organic content (VOC). Unlike other types of sealants, this category is relatively harmless to environments or occupants with high chemical sensitivity and does not require special treatment for disposal of excess waste. There are also no additional PPE requirements.

Water-based sealer is versatile and available in a variety of tints, colors and finishes from matte to gloss. It is also extremely safe and poses no flammability and combustibility hazards.

For all their excellent qualities, water-based sealers have some limitations, including:

A greater preparation time requirement

A softness for your cured film

A variability in drying time

Variable stain protection performance – while some sealers are effective with just one coat, others may require two or more applications

They are also sensitive to material types, meaning solvent-rich topcoats can damage them, and they can be repelled by high levels of silicone in surfaces.

You can’t use this type of sealer in surface and air temperatures below 45 degrees Fahrenheit, and not all water-based solutions apply equally, meaning some require brushes or rollers, while others are available as airless sprays.

Shellac fire and smoke damage sealers

Consisting primarily of processed lacquer resin secreted by insects native to Indonesia and India, this sealant is made by suspension in alcohol. Historically, shellac was the most commonly used sealant in fire damage restoration due to its primary ability to control burnt odor. In fact, it has a decades-long history of successfully sealing smoke odors in treated surfaces. This sealer is available at almost all paint centers and paint retail stores and is the most expensive type.

Shellac possesses several useful properties, including its ability to be cured and applied at much lower temperatures than other sealer formulations – down to 10 degrees Fahrenheit. It can also:

Stick to hard or difficult surface conditions

Accept almost any type of top coat as a primer

Dry in under 30 minutes for maximum recovery efficiency

Once dry, the cured surface is extra hard compared to other sealers and is ideal for stopping stains.

In addition to its laudable properties, shellac has some limitations, so make sure its properties match your project.

This special seal is moisture vapor impermeable, meaning it can trap moisture and create a barrier to condensation. It can also become brittle when subjected to direct impact, making it an unsuitable choice for outdoor use. Remember that shellac requires special attention when cleaning with denatured alcohol and exposing its vapors to ignition can be dangerous.

Shellac also requires special treatment – in the form of solvent recycling – for the disposal of excess material. While it prevents smoke odours, it also leaves an unpleasant paint smell for up to a week which may require carbon filtration to eliminate completely. It also requires PPE for the application, such as B. Respirators to make it safe to inhale and you should be aware of regulations regarding maximum VOC levels which may make it unavailable in certain areas.

Alkyd based fire and smoke damage sealant

Alkyd primers are oil based and are typically more commonly used to seal water stains. None are technically intended for fire remediation, but they can serve these types of applications. Waterborne alkyds and other hybrid coatings are emerging within this category. Alkyds are typically available at hardware and retail paint stores and are among the most inexpensive sealer formulations.

Alkyds have a number of positive properties including their tolerance of difficult or imperfect surface conditions, excellent stain blocking abilities and fast drying abilities. This sealer is also easy to sand and, once thoroughly cured, will accept almost any oil or water based top coat as a primer.

Limitations of alkyd based sealers include:

Uncertain permeability or lack of permeability

Expected VOC Restrictions

PPE Requirements

flammability and combustibility

Persistent smell

Special requirements for waste treatment

Alkyds also require extensive mixing before application, and they involve a lengthy cleaning process with mineral spirits, which can increase exposure to solvents and cost more labor and productivity.

Fixative fire and smoke damage seals

Fixative sealant formulations are particularly low in solids, helping residual particles adhere to surfaces and prevent them from contaminating the air and becoming respirable. This can be useful for isolating and eliminating toxins to stop further circulation after fire damage cleanup, but is not particularly useful for preventing further surface damage or preventing smoke stain penetration as it does not form a tactile film.

The Do’s and Don’ts of Smoke Damage Sealers

With the details of sealant uses, categories and considerations, you are almost ready to properly incorporate them into your fire damage restoration projects. Just make sure you follow these crucial do’s and don’ts with any smoke damage sealing procedure.

Do:

Consider the needs of each project. This can include environment, exposure, extent of damage and future function of the structure. Being careless in choosing your sealer can prevent the site from reaching its full recovery potential in the future and can lead to problems later. Use a product intended for fire or smoke damage. Take extra care to select a sealer that you know will counteract smoke damage and odors, especially in a structure with extensive damage or in a sensitive environment. As the categories above show, some sealers – like alkyds – are meant for other purposes, so handle them with care and always choose the product that’s specifically designed to do the right job. Pay attention to the preparation of your seal. Some sealants require extensive mixing or safety preparation before use, and failure to meet these requirements or misuse can result in damage or a hazardous condition. Before you choose your sealant, find out exactly how it is prepared and used.

Carry out proper cleaning and waste disposal. Some sealants are safer while others are flammable, hazardous, high in VOCs and specific to PPE and toxic waste requirements. To ensure health, safety and effectiveness, make sure you are familiar with the proper handling and disposal of any materials you use.

Do not:

Use seals to cover up bad work. It is imperative that a structure be fully cleaned, deodorized and decontaminated before applying a smoke damage sealant. Sealers cannot cover up remaining contamination or incomplete cleaning work – they can only serve to prevent additional stain spread and odor escape. Just use any paint primer. Specially designed for damage treatment, sealers are the only coatings you can use to cover smoke damage and block smoke odors. Using an ordinary paint primer on smoke and fire damaged surfaces will create an incompatible situation and will only result in further damage to the surface.

Use sealers alternately. Each seal has unique traits, properties, and limitations that make it better suited to specific environments and situations. Never assume that two different types of sealant will do the same thing or that you don’t need to research their use in relation to the specific project. Choose the most suitable seal and do not mix types.

Never assume that two different types of sealant will do the same thing or that you don’t need to research their use in relation to the specific project. Choose the most suitable seal and do not mix types. Be carefree when using and cleaning. Just as each sealer has different properties, the procedures for preparing, applying and disposing of the coating vary depending on the type of formulation. Pay close attention to the handling instructions for your particular sealer to ensure the coating is effective, the process is safe, and dry cleaning is performed properly.

Always use fireproofing with care and consideration and wish you the best of luck in your fire damage restoration projects.
