C2 Guard for Masonry is a non-toxic product designed for unsealed concrete and masonry surfaces. C2 Guard is absorbed deep into the surface, forming a polymer barrier and becoming part of the masonry’s structure. This enhanced structure resists water penetration and helps prevent corrosion, cracks, and mold/mildew.
Best of all it helps protect concrete and masonry from de-icing salts and pool chemicals.
👍 This is our top pick for preserving concrete and masonry.
