Black Mastic Asbestos: Identification, Risks, and Removal

What is Black Mastic Asbestos?

Black mastic is a type of adhesive used to install flooring in homes built before the late 1980s. It is made of asphalt, cement, and sometimes asbestos. Asbestos is a mineral fiber that was added to mastic to make it stronger and more durable.

Health Risks of Asbestos Exposure

Asbestos is a known carcinogen, and exposure to asbestos fibers can cause serious health problems, including:

  • Mesothelioma, a rare and aggressive type of cancer that affects the lining of the lungs, chest, or abdomen
  • Lung cancer
  • Asbestosis, a scarring of the lungs that can lead to shortness of breath and other respiratory problems

Identifying Black Mastic Asbestos

Black mastic is typically black or dark brown in color. It is often found under old flooring materials, such as linoleum or vinyl. However, not all black mastic contains asbestos. To determine if your mastic contains asbestos, you should have it tested by a qualified professional.

Manufacturers and Brands of Black Mastic Asbestos

Several manufacturers and brands produced black mastic adhesives containing asbestos. Some of the most common include:

  • Armstrong
  • Johns-Manville
  • Congoleum
  • GAF
  • CertainTeed

What to Do if You Find Black Mastic Asbestos

If you find black mastic in your home, it is important to take the following steps:

  • Do not disturb the mastic. Abrading or sanding the mastic can release asbestos fibers into the air, which can be harmful to your health.
  • Test the mastic for asbestos. You can purchase a DIY asbestos testing kit or hire a professional to test the mastic for you.
  • If the mastic tests positive for asbestos, have it removed by a qualified professional. Asbestos removal is a specialized process that should only be performed by trained and certified professionals.

Removal and Encapsulation of Black Mastic Asbestos

The safest way to deal with black mastic asbestos is to leave it undisturbed and encapsulated. This means covering it with a new layer of flooring or other material to prevent the release of asbestos fibers.

If removal is necessary, it is important to follow all safety precautions to avoid exposure to asbestos fibers. This includes wearing a respirator, gloves, and protective clothing.

Importance of Professional Asbestos Removal

Asbestos removal is a complex and dangerous process that should only be performed by trained and certified professionals. Attempting to remove asbestos yourself can put you and your family at risk of exposure to harmful asbestos fibers.

Preventive Measures

The best way to protect yourself from asbestos exposure is to avoid contact with asbestos-containing materials. If you are unsure whether a material contains asbestos, have it tested by a qualified professional. You can also take the following steps to reduce your risk of exposure:

  • Wear a respirator when working with or around asbestos-containing materials.
  • Wet down asbestos-containing materials before disturbing them.
  • Seal off areas where asbestos-containing materials are present.
  • Have asbestos-containing materials removed by a qualified professional.

Understanding Cutback and Water-Based Mastic Adhesives

Cutback mastic is a type of adhesive that is made with asphalt and is not water-sensitive. Water-based mastic, on the other hand, is made with latex and can be softened with water. Cutback mastic adhesives are more likely to contain asbestos than water-based mastic adhesives.

DIY Asbestos Testing Kits

DIY asbestos testing kits are available for purchase online and at home improvement stores. These kits allow you to collect a sample of the suspected material and send it to a laboratory for testing. However, it is important to note that DIY asbestos testing kits are not always accurate. If you are concerned about the accuracy of a DIY test, you should have the material tested by a qualified professional.
