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.
On new concrete each gallon will cover 200 square feet per gallon. On old concrete, each gallon will cover up to 150 square feet per gallon. Areas with crazing (fine cracks on the surface) may take two applications.
