Our Review
The USG Durock Liquid Waterproofing and Crack Isolation Membrane is designed to handle demanding wet environments, including showers and steam rooms. Its acrylic polymer-based formula is versatile enough to be applied by rolling, brushing, troweling, or even spraying, making it adaptable to different project needs. It is compatible with a wide array of substrates like concrete, masonry, and cement backerboard.
What sets this product apart is its low permeance rating of 0.38 perms at 20 mils, which qualifies it for use in continuous-use steam showers without needing extra vapor retarders. It is a solid choice for both commercial and residential installers who need a heavy-duty product that changes color as it cures, helping you verify when the area is ready for the next step.
Standout Features
The membrane is notable for its anti-fracture protection, which covers non-structural cracks up to 1/8 inch. It is specifically engineered to meet strict industry standards for steam rooms, providing peace of mind for moisture-prone areas.
What We Like
We appreciate the user-friendly color-changing feature, which makes it easy to monitor the curing process visually. The versatility in application methods is also a huge plus, allowing you to choose the best tool for your specific wall or floor layout.
