About USG Durockâ„¢ Liquid-Applied Waterproofing Membrane
USG manufactures building materials used across construction and tile installation applications. USG Durockâ„¢ Liquid-Applied Waterproofing Membrane is designed for waterproofing and crack isolation in tile and stone installations where moisture management and substrate protection are required.
This liquid-applied membrane is installed prior to tile installation to help protect substrates from water penetration and to accommodate minor in-plane movement. It is commonly used in residential and commercial environments where wet conditions are present.
Primary Functions
- Waterproofing: Creates a continuous barrier to help prevent moisture from reaching the substrate.
- Crack Isolation: Helps manage minor substrate movement to reduce the transfer of cracks to the tile surface.
- Surface Protection: Protects approved substrates prior to tile or stone installation.
Where It Is Used
- Showers and tub surrounds
- Bathrooms and restrooms
- Kitchens and laundry rooms
- Floors and walls in wet or damp areas
- Interior and exterior tile installations
How to Choose
- Installation Environment: Confirm the membrane is rated for interior or exterior use.
- Substrate Type: Verify compatibility with cement board, concrete, masonry, or other approved surfaces.
- Application Method: Liquid-applied membranes are typically applied by roller, brush, or trowel.
- System Compatibility: Ensure compatibility with thin-set mortars and tile systems being used.
Performance Benefits
Using a liquid-applied waterproofing and crack isolation membrane helps extend the life of tile installations by reducing moisture-related damage and minimizing the impact of minor substrate movement. USG Durockâ„¢ Liquid-Applied Waterproofing Membrane supports consistent installation performance in demanding environments.
