Sealing basement slab before installing carpet tiles?

Posted by bert76 (My Page) on

My husband thinks we need to seal our basement floor before laying down carpet tiles (either FLOR commercial closeouts or Milliken Legato tiles).

I've looked into RedGard and RadonSeal, but I'm stumped with what to do next. I want to do it right, but I also don't have a ton of money to spend on this space, which primarily will be a playroom for our four young children.

The house is 40 years old and had previously had wall-to-wall carpeting with pad, which we ripped out after a sink overflowed. Then we discovered the floor had been laid previously with some sort of tile because we can see the old black adhesive on the concrete in the shape of tiles (I'm guessing it was vinyl tiles).

When we moved in a year and half ago, we passed the radon test, but we do live in the Midwest with thick clay soil, so radon is always a risk.

I did tape down two one-foot sheets of plastic in different areas and had no condensation (although both were done over the black adhesive residue). But the basement does feel damp in the summer, and we do have a sump pump on the other (unfinished) side of the basement.

Any guidance is greatly appreciated.

With Milliken Legato you do not need to seal unless you have an apparent water problem.

We put 12x12 self stick carpet tiles in our basement directly over concrete. They adhered well, and we have not had any problems.
