You want to make sure you make an informed decision when buying paint to cover your asbestos siding. To do so, it’s important to know what options you have and how they work. Read on...
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.
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.

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