I have a house built in 1968 and in the basement the floor is covered with 12X12 vinyl tile.

I had sent the sample for asbestos testing and it came back negative for tile itself however the black mastic on the tile has 6% asbestos.

My questions are

  1. What are my option to cover the floor?(I am thinking of putting floating vinyl planks) - the floor is in good condition overall except few tile which are chipped and cracked.
  2. Should I paint the floor (so that it encapsulates the material) and then cover it with floating vinyl floor or some other product?
  3. If I were to go for floating floor then I will face problem with slop since there is a drain in the center, how would I deal with slop for laying a floating floor?

    Asbestos is very bad if you start doing stuff like sanding it, if left alone it is almost safe. Most hard material flooring wants/needs a floor surface to be flat. Does not need to be level, slope if floor is flat it can have a slope in one direction only. If slope is in multiple directions, will need to use soft type flooring(carpet, vinyl) or small size hard type flooring(12x12 inch).

    "Best" and "should" are opinion based. "What are my options" isn't, but it's pretty broad. "I'm considering A and B what are the pros and cons" is objective and the kind of question we can answer and is on topic here. Please edit your question to make it more on topic.

The mastic is encapsulated by the tile, if there is any mastic showing paint that piece.

If you want a new floor covering that will work with the floor drain well drop the floating floor idea or add a hydroponic heating system this reduces the ceiling clearance so it’s not for everyone but it can make a nice warm difference.

I have also tiled directly over those tiles and that worked out well so there are many options but I have not had good experience with floating flooring on sloped surfaces and worse where it was wet.
