FAQ:

Q: Where to buy radonseal?

A: Mastic removers are also sold in stores. But avoid filling the pores in concrete with diluted adhesive or mastic, which could make the concrete unsealable! We recommend our Lightning Strip Paint & Mastic Remover, particularly for the old, thick, black mastic. Test it on a small area first.

Q: Does radonseal work?

A: Their sealers do block a certain amount of moisture from the sub-base from coming up through the concrete. But like any moisture mitigation product, they are only rated for blocking a certain amount of moisture. If you just have a damp, musty smell in the basement, then you should be just fine using Radonseal’s sealer.
