USG Durockā¢ Liquid Waterproofing & Crack Isolation Membrane
USG Durockā¢ Liquid Waterproofing & Crack Isolation Membrane provides liquid-applied waterproofing and crack isolation beneath compatible ceramic tile, porcelain tile, natural stone, and other finished surfaces. Once cured, the membrane forms a continuous waterproof barrier over approved substrates while helping isolate minor in-plane substrate cracks that could otherwise transfer through the finished tile assembly.
USG Durockā¢ Waterproofing & Crack Isolation
Liquid-Applied Waterproofing Membrane
The liquid-applied formulation can be rolled, brushed, or troweled onto approved substrates, providing coverage across walls, floors, corners, transitions, and irregular surfaces. It is suitable for compatible moisture-prone tile installations where continuous waterproofing beneath the finished surface is required.
Crack Isolation for Tile Installations
In addition to waterproofing, the membrane provides crack isolation to help accommodate minor in-plane substrate movement beneath compatible tile and stone assemblies. This combination allows a single membrane to address both moisture protection and applicable crack-isolation requirements.
Choosing USG Durockā¢ Waterproofing Membrane
Consider USG Durockā¢ waterproofing membrane according to the substrate, installation environment, finished tile or stone, and required waterproofing and crack-isolation performance. It can be used in compatible showers, tub surrounds, bathroom floors, kitchens, laundry rooms, and other interior or exterior tile applications where liquid-applied membrane protection is appropriate.
