Concrete floor sealer recommendations
I recently stripped the paint off my basement floor with a diamond grinder attached to a floor buffer.

While the floor still had paint on it, I had it covered for a couple months with a roll of dimpled plastic to be used as a subfloor. I lifted it one day to see mold covering 1/6 of the 420 sq' floor and the paint in those areas was easily scraped off.

i think the problem is with grading around the house which I will address with added dirt.

Can anyone recommend a good concrete sealer?
