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 concrete.

AVAILABLE SIZES

• 1 Gallon (Case of 4)

For use with all concrete coatings including Rust-Oleum, EPOXYSHIELD and RockSolid
