Percolation Tests questions, answered by experts

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Professionals use specialized equipment and techniques to detect asbestos, radon, and VOCs.

You can tell if old flooring has asbestos if thick black flooring adhesive is underneath the tiles. However, homeowners should not cut into linoleum floors to look for this adhesive. Instead, hiring a specialist to test the floors is the only safe way to determine if old flooring has asbestos.

Through air sampling devices and surface swabs in key areas of concern.
