Our Overall #1 Rated Pick

Updated On March 19, 2021

Fiberlock is the gold standard when it comes to covering up asbestos siding and preventing any potentially-harmful exposure to chemicals.


This product has been certified and tested by both the EPA and Underwriter’s Laboratories as a barrier solution for asbestos siding, making it one of the most-trusted names in the business.  


Additionally, it is designed to mimic many of the same qualities, including texture, flame retardancy, and insulation as the underlying asbestos, making it a nearly-indistinguishable covering for your walls.


PURCHASE NOTES:
1)  You won't see many reviews on Amazon because pros buy this from their paint stores with their corporate discounts. But, if you're like me, you prefer the ease and pricing of Amazon.


2) Note that this is a 5-gallon bucket, so the cost per gallon is quite reasonable.

What Are Paints for Asbestos Siding? 

Asbestos and mesothelioma are two terms people are becoming very familiar with.  

Asbestos is an older material that was commonly used in siding and insulation for houses.  It was a very effective insulation, but it has the unfortunate side effect of causing cancer.  It has also been used extensively in fiber cement siding, which can make applying a top coat of exterior paint a stressful event.

Fortunately, it will not harm you unless the asbestos dust is stirred and breathed in.  

Because of this, it’s important that all asbestos be treated carefully, especially when painting asbestos siding.

Instead of replacing asbestos siding on an old house, homeowners have the option of treating it with specialty paint that will prevent any exposure to the dangerous chemicals.  

These paints seal the asbestos and prevent it from spreading as dust particles.  

And that keeps your loved ones safe from harm and ensures that the siding will last for a while longer.  

Fortunately, asbestos paint is also useful for changing the color of your siding so that your house can be updated without having to go through all the expense of buying brand new siding.

Did you know: Asbestos siding was one of the most common materials used on homes from the 1920's through the 1980's.

What are the Different Types of Paint for Asbestos Siding?

There are a couple of different options when you are painting asbestos siding. The two main types are encapsulants and latex paints.  

Both types are latex-based, which is important because latex creates a permanent barrier that protects the asbestos from exposure and prevents it from releasing.  

When latex-based paint sets, it bonds to form a latex polymer layer that is impervious to water, air, and sun.

The main difference between the two types of asbestos paint is their strength.

An encapsulant is a heavy-duty latex paint that binds much more solidly to create a permanent barrier.  

Latex paint, on the other hand, typically requires a strong primer that helps create a more solid barrier.  

They are both effective, but an encapsulant will last significantly longer.

How Does Paint for Asbestos Siding Work? 

Paint for asbestos cement siding works by creating a permanent, polymer-based barrier between the asbestos and the elements.  

The danger of asbestos lies in the particles that escape and can be inhaled.   Untouched asbestos is just as safe as any other siding or insulation.

Unfortunately, asbestos never remains truly untouched because of nature.   Sunlight and rain can help break it down, while air will move it around, causing residents to breathe it in and become exposed.

Latex encapsulants and paint will create an impermeable barrier that prevents water, sunlight, and air from contacting the asbestos.  This prevents the siding from breaking down further and ensures that no more volatiles are released into the environment.  

Beyond that, it also acts to keep the asbestos contained.  By creating a barrier around the siding, it acts like a fence, preventing asbestos particles from escaping into the surrounding air.   This protects passersby and residents from accidental exposure.  Some of these paints can prevent asbestos release for decades.

And to state the obvious, refrain from sanding your asbestos siding before painting it. If you have any chipping, flaking, or loose paint particles to remove, scrape them lightly while wearing a respirator and other protective clothing.

Capture and dispose of the scraped paint in plastic that is then rolled up and taped shut before properly disposing in accordance with your localities' toxic waste regulations.

What to Look for in the Best Paint for Asbestos Siding  

When you’re looking to buy paint to seal your old asbestos siding, there are a few main things to look out for.  

First, you’ll want to buy a product that contains latex.  

Depending on your budget, you can buy a latex encapsulant (which is the strongest option), a latex-based paint and primer, or a latex primer with a regular water-based paint.  

It is vital that the first layer in contact with the asbestos siding is latex.

Another thing to consider is the longevity of the paint.  

A stronger paint will last longer, preventing you from being exposed to asbestos for a longer period of time.  

A heavy-duty encapsulant will provide the longest-lasting protection, potentially on the order of several decades depending on the exposure.  

A simple latex primer with regular paint will likely need to be reapplied in several years.

You want to make sure your paint will hold up to any potential sanding or other type of disturbance.  

Verify that the paint will not be damaged if you power wash it.  This will be important for the cleaning and caring for the paint job in the future.

Finally, consider your color.  Latex paint discolors differently than standard water-based paint.  

Make sure to keep this in mind when you’re looking for colors for your paint job.

Reviews Of The Best Paint For Asbestos Siding

Our #1 rated pick, Fiberset PM is the gold standard of paint for asbestos siding. 

Fiberset PM is a pre-mixed, lockdown sealing treatment for microscopic asbestos fibers.

It's water-based for easy cleanup.  

And it's not very expensive on a per-gallon basis.

It's what the pros use!

Pros

  • Performs all six types of asbestos abatement
  • Effective for 20 years, guaranteed
  • Maintains fire resistance

Cons

  • Limited color selection

If you’re looking for a high-end, powerful option for your asbestos covering needs, ABC Asbestos Binding Compound is one of the most potent coverings in the industry.  

It's designed to perfectly encapsulate all asbestos containing material and is rated as one of the best in prevention of exposure to asbestos fibers.  

While it's the best choice for highly-critical applications, it may be a step above what a homeowner needs.

Pros

  • Highest-rated for encapsulating asbestos
  • Most-penetrating product

Cons

  • Limited color selection
  • Most expensive option
  • Longer drying time

Pick #3: Cinder Block Semi-Gloss Exterior Paint

Cinder Block Semi-Gloss Exterior Paint is a base-level solution for asbestos abatement.  

It's a latex combination exterior paint that can be used on masonry and siding.  

Testing shows it should perform adequately to prevent exposure to asbestos during its rated lifetime, which is typically about 3-5 years.  

And because it's a standard latex paint as opposed to a specific encapsulant for asbestos, you can find a wider range of colors and finishes, as well as sizes for purchase.  

So when you want to paint asbestos siding a preferred color, this product is a great top coat.

Pros

  • Sold in smaller quantities
  • Best color selection

Cons

  • Minimal penetration
  • Must reapply every few years
  • Does not improve fire resistance

Lead and asbestos are different compounds, but they are dangerous in similar ways.

Because of this, an encapsulant like the ones offered by Child Guard is an excellent substitute for a specifically asbestos-blocking compound.  

Child Guard Encapsulating Paint is also known to hold up well to power washing, which makes it an extremely safe alternative.

Pros

  • Useful for lead and asbestos
  • Child-safe formulation

Cons

  • Not the longest lasting
  • Expensive
  • No improvement for fire resistance

Kilz latex paint and primer combination is another product that can be used for covering asbestos siding.

However, this affordable option has numerous limitations, and is one of the shortest-lasting products.

It's best as an effective short-term solution for those on a limited budget.

Pros

  • Affordable
  • Effective short term solution
  • Paint and primer in one

Cons

  • Very short life
  • May require multiple coats to ensure coverage

Fiberlock 7470 Fiberset PM Encapsulant is our top pick.

Final Thoughts On The Best Paint For Asbestos Siding

Asbestos is not something to mess around with.  The fibers and dust from asbestos siding or insulation can cause serious long-term health issues.

The best choice for those who are unable to remove and replace the siding on their house is to use a proven encapsulant or paint that will prevent exposure to the harmful chemicals.  

If you do it right, you will have lasting protection for over 20 years on your asbestos siding, which is potentially even longer than vinyl siding would have lasted.  

Whether or not it’s a true encapsulant, make sure to use something that is latex-based and is rated for use on asbestos siding.  Get it done right, and keep your family protected.
