Merkrete Hydro Guard 1 Waterproofing Membrane, 3-1/2 Gallon

Merkrete Hydro Guard 1 is a load-bearing membrane made of a modified elastomeric copolymer that is thin and flexible. Hydro Guard 1 delivers a 100 percent waterproof membrane covering while preventing the transfer of substrate cracks to the finished overlay thanks to its exceptional elongation capabilities and strong strength. The membrane is implanted in a liquid condition and can be used to create almost any shape or form (i.e., base flashings, parapets, walls, etc.).
