Rust-Oleum 1 gal. Moisture Stop Floor Coating

Rust-Oleum Moisture Stop penetrates deep into concrete and reacts with free calcium and water to form a gel inside cracks, pores, and capillaries. This specialized formula strengthens and seals from the inside out to protect against the ingress of water, moisture vapor, and contaminants. By preventing moisture from coming through concrete floors, this treatment prepares surfaces that were previously uncoatable due to excessive moisture, allowing for proper topcoat adhesion and long-lasting protection.
