Asbestos in Caulking

Caulking is used for the sealing of joints and seams in construction structures. It is also used in making some types of piping systems. Asbestos materials were popularly used in the making of caulking products as they were highly resistant to heat, water and weather changes. In many cases, the fibres were used to make 100 percent of the caulks.

It is highly dangerous if the fibres are released into the air. This only happens when the caulk is damaged by force, drilling, age or even water. That is why you should never attempt to remove the parts just because you suspect they have carcinogenic asbestos components. Instead, you should carry out asbestos surveys and contact a removal company for a safe process. Leaving dangerous caulking in your house or construction project is also not advisable.


We provide a range of Asbestos Management Survey, Asbestos Refurbishment & Demolition Surveys and Asbestos Sampling Services for all types of Asbestos Containing Materials (ACM’s) including Caulking, Sealers and Mastics.

Asbestos in Sealers

Sealers are used to prevent the passage of fluids through openings in buildings. Once exposed to air, sealers solidify and make it impossible for fluids to go through the parts of a construction project. Usually, sealers are used to block openings in roofing, cement and floor tiles.

Some buildings in the 1980’s were constructed using sealers that contain asbestos fibres, but their use has ceased because of government regulations and increased awareness of their effects to health.

Asbestos in Mastic

Mastic is an organic-based adhesive used in flooring.  Asbestos was primarily used in the making of some of these mastic adhesives because of its durability and its capacity to resist fires making it an ideal choice at the time for use a flooring adhesive.

Most homes and building that were put up in the late 20th century are likely to some for of asbestos containing materials (ACM’s). These mastics were, especially popular in the 1980’s.
