Merkrete Hydro Guard SP-1 is a fast-drying thin, load-bearing waterproof and crack isolation membrane composed of modified elastomeric copolymers. With excellent elongation, adhesion and high strength properties, Hydro Guard SP-1 provides a 100% waterproof membrane that limits the transfer of substrate cracks to the finished ceramic or stone tile surface. Hydro Guard SP-1 is installed in a liquid state and can be applied to practically any form or irregular shape forming a monolithic waterproof barrier.
Hydro Guard SP-1 is for use in commercial buildings, residential housing and other areas requiring positive waterproofing like pools, fountains, spas, hot tubs, kitchens, countertops, balconies, tub surrounds, shower stalls and pans, under terrazzo, quarry, ceramic and stone tile. This membrane can be installed over any sound substrate, vertically or horizontally, interior and exterior.
