Moisture Stop Fortifying Sealer

Rust-Oleum® Moisture Stop penetrates into concrete and reacts with the free calcium and water to form a gel in cracks, pores and capillaries to protect against the ingress of water and contaminants. This allows surfaces that were previously uncoatable, due to moisture, to be coated. 

  • For use on concrete prior to coating
  • Prevents moisture from coming through concrete floors
  • Strengthens and seals from the inside out

For Best Results

  • Always test for moisture prior to applying a coating. Perform the moisture test again after using Moisture Stop.
  • For use with all concrete coatings including Rust-Oleum, EPOXYSHIELD and RockSolid
