During the mid 20th century, contractors used black mastics routinely as a glue-like flooring adhesive. If your house was built before 1989 – the year it was banned – the black mastic adhesive used is almost certain to contain asbestos due to how effective and cheap it was to make and use. Manufacturers at that time did not know about the potential health risks of asbestos and added it to their black mastic products.

In addition, once completed, the floors are left with an oily residue and cannot be painted.

Some people try to use mastic dissolvers such as Blue Bear or Fran Mar Been e Doo to remove black mastic from their floors. Unfortunately, these products cannot be safely or legally used by anyone who is not a certified abatement contractor wherever asbestos mastics are involved. Furthermore, once the mastics are dissolved using these products, it is almost impossible to paint or apply cements or epoxies to the floor, as the oil and residue left behind in the pores of concrete prevent any new coatings from bonding with the surface.

Mastics can also be removed by grinding or shotblasting, but only if done by asbestos abatement certified professionals who are proficient at grinding cutback glue and asbestos black mastic.
