Crack Isolation, Waterproof Membrane Liquid, 3.5 Gallon Merkrete Hydro Guard 1

Hydro Guard 1 is a single component waterproof membrane used for residential and light commercial applications that does not require fabric reinforcement. Easy to use liquid that can be applied to nearly any job situations, as well as the low VOC make this waterproofing/crack isolation a solid choice.

Technical Data: Merkrete Hydro Guard 1 is a thin, load bearing membrane composed of a modified elastomeric copolymer. With excellent elongation properties and high strength, Hydro Guard 1 provides a 100% waterproof membrane coating while 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.).

Where to use: Hydro Guard 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.
