What to know about Asbestos Drywall
Asbestos can be found in older drywall, particularly in the joint compound, also known as "mud," that is used to seal seams between drywall sheets. This compound was commonly mixed with asbestos fibers to improve its durability and performance, especially in homes built before the 1980s. Asbestos in the joint compound poses a risk if the drywall is disturbed during renovations or repairs, as the fibers can become airborne and be inhaled. It’s important to note that the presence of asbestos drywall joint compound is more likely in homes built before asbestos was banned in many building materials, so if you’re working in an older property, it’s essential to have the material tested before disturbing it.
When Did They Put Asbestos Drywall
​Asbestos was commonly used in drywall joint compound, or "mud," from the 1950s through the late 1970s due to its beneficial properties, such as durability, strength, and heat resistance. Builders added asbestos to the compound to enhance its performance, making it more resistant to cracking and providing a smoother finish for drywall seams. This widespread use of asbestos continued until the late 1970s when its health risks, particularly the link to serious respiratory diseases and cancers, became more widely understood. As a result, regulations were introduced to limit and eventually ban the use of asbestos in building materials, including joint compound. However, many older homes and buildings still contain asbestos in their drywall, which remains a risk if disturbed during renovations.
How to tell if you have asbestos drywall
Identifying asbestos drywall joint compound can be tricky since it often looks like regular compound, and there are no visible signs of asbestos. If your home was built before the 1980s, there’s a higher chance that the compound may contain asbestos, as it was commonly used during that time. However, the only definitive way to know if asbestos is present in your drywall joint compound is through professional testing. Attempting to check for asbestos yourself can be dangerous, as disturbing the compound could release harmful fibers.

What if you have asbestos in plaster
Asbestos was commonly added to plaster in homes built before the 1980s due to its fire-resistant properties, durability, and ability to improve the overall strength of the material. It was particularly used in the base coat of plaster, which was applied over lath (wooden slats or metal mesh) to create a solid, smooth surface. Asbestos-enhanced plaster helped improve the material’s resistance to cracking, thermal insulation, and soundproofing. It was popular in the construction of homes, schools, and commercial buildings. However, as awareness grew about the severe health risks associated with asbestos exposure, regulations were put in place to limit its use in construction materials by the late 1970s.
If you live in an older home, it’s possible that your plaster contains asbestos, particularly if it was installed before the 1980s. Common signs that plaster may contain asbestos include the texture of the plaster, which could have a rough, fibrous appearance, or if it's part of the original construction in a building built before asbestos was regulated. However, these visual cues aren’t a guarantee, as asbestos fibers aren’t visible to the naked eye. The only sure way to determine whether your plaster contains asbestos is to have it professionally tested. If you're uncertain, it’s best to consult an expert to ensure your safety before attempting any renovations or repairs.
What to do if you have asbestos drywall
If you identify asbestos in your drywall, it’s important to take immediate precautions to prevent exposure. First, avoid disturbing the area—do not touch, scrape, or drill into the asbestos drywall, as this can release harmful asbestos fibers into the air. Seal off the room if possible to prevent the spread of any fibers and keep the area well-ventilated. It's crucial to contact a professional asbestos mitigation company who can safely assess the situation, take samples for testing, and develop a plan for mitigation. These experts have the proper equipment and knowledge to handle asbestos safely, minimizing the risk to your health and the environment. Never attempt to remove or handle asbestos-containing materials yourself; always leave it to trained professionals.
