How to Recognize Asbestos in Home Paint

How to Recognize Asbestos in Home Paint

Prior to the 1980s, asbestos, the ideal construction material, was used in almost every residential, commercial, industrial and public building in the U.S. Its excellent thermal transfer properties made it suitable for use in thousands of products from floor tiles to fireproof adhesives. At that time, asbestos was commonly used as an ingredient in paints and could potentially be present in any home constructed in the 1970s or before.

Before discovering the hazardous effects of asbestos on people's health, using it in paint seemed like a revolutionary idea for the industry. This idea relied on the mineral's availability, which made it very cheap, as well as on its excellent properties. Asbestos is a lightweight, chemically stable, non-corrosive material which does not conduct electricity and increases the holding power of paint products.

Some types of paint in which asbestos was often included are:

  • Textured ceiling paints
  • Paint patching compounds
  • Joint compounds

When renovating an older house, homeowners need to know whether or not asbestos was used in the paint or building components. Asbestos detection should be performed to make sure that remodeling doesn't release harmful asbestos fibers into the air.

Asbestos Inspection Is Important Before Refurbishment and Demolition Projects

Asbestos spray coating was commonly used to insulate a roof and sometimes the sides of buildings between the 1940s and 1980s. It looks like a rough layer of either white or gray paint. For example, if you check the underside of your roof in your attic, you will see a layer that looks like it was sprayed on.

Manufacturers of texture paint containing asbestos include:

  • Kelly-Moore Paint Company
  • U. S. Gypsum Company
  • Bondex International, Inc.
  • Proko Industries Inc.
  • Sherwin-Williams Paint Company
  • W.R. Grace & Co

Because they are particularly friable and highly susceptible to damage either by impact or water, asbestos sprayed coatings are considered one of the most dangerous forms of asbestos-containing materials. Containing as much as 80 percent asbestos, asbestos sprayed coatings were manufactured using 3 asbestos fibers types: chrysotile, amosite, and crocidolite.

Asbestos-containing texture material was produced and used as a surfacing material on walls and ceilings and finished with paint coatings. Asbestos filler was commonly found in many paints throughout the twentieth century and used to add dimension to walls and ceilings. It has become a desirable filler to also add flame resistance to structures. Additionally, manufacturers observed that asbestos materials allowed liquid paint to flow well and stay stable in hot and cold environments. Asbestos additives have also been developed in order to enhance the color of the paint.

When Damaged, the Risk of Fibers Becoming Airborne Is Considerable

Asbestos-containing paint doesn't pose a danger when it goes undisturbed, but when the paint starts breaking down and flaking, the microscopic asbestos particles become airborne being easily inhaled or ingested without even being aware of it.

Understanding the basics about asbestos and its health risks is key to avoiding contact and protecting yourself against unwanted asbestos contamination. Careful remediation and transport must be performed when handling the dangerous substance and ensuring you have sufficient protection is an absolute must.

Why Should I Test Products in My Home for Asbestos?

It is often impossible to tell whether asbestos is embedded in a material, as the fibers are too small to be observed with the naked eye. Exposure to asbestos is responsible for serious respiratory conditions, so thorough testing is required to ensure your home is asbestos-free.
