Merkrete Hydro Guard 2000 is a heavy duty, thin, load-bearing membrane composed of a modified elastomeric copolymer. With excellent elongation properties and high strength, Hydro Guard 2000 provides a 100% waterproof membrane coating in addition to performing as a crack isolation membrane, limiting the transfer of substrate cracks to the finished overlay. The membrane is installed in a liquid state and can be applied to practically any form or irregular shape (i.e. base flashings, parapets, walls, etc.).

Hydro Guard 2000 is ideal for use in commercial buildings, residential housing and other areas requiring positive waterproofing like pools, fountains, steam rooms, 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.
