A shower only stays a shower if the water stays where it belongs. Blanke Aqua Shield is a thin bonded-fabric waterproofing membrane and vapor barrier that you apply with thinset to dry, flat, structurally sound surfaces, and then tile the same day.
This tile waterproofing membrane is designed for demanding wet-area installations, including shower stalls, bathrooms, spas, and steam rooms. Its vapor barrier properties make it suitable for steam-room applications, while its high tensile strength provides long-term protection in continuous wet areas. The German-engineered fiber blend also resists mold, strong chemicals, and UV exposure for a durable waterproofing layer behind the tile.
Aqua Shield is a system, not just a sheet. Tie the field waterproofing membrane together with the matching accessories, including Aqua DB banding for seams and movement joints, preformed inside corners and outside corners, the WM pipe collar, and Aqua Seal adhesive to create a continuous waterproofing assembly.
Blanke Aqua Shield is designed for waterproofing tile installations where moisture and vapor protection are critical. Common applications include:
Because the membrane is bonded with thinset, installers can create the waterproofing layer and move forward with tile installation the same day without waiting for a liquid waterproofing product to cure.
Pro tip: Full thinset coverage is critical when installing the waterproofing membrane. Avoid voids behind the membrane and embed it fully so there are no air pockets or wrinkles. Properly treat every seam, corner, transition, and penetration with the appropriate matching system accessories according to Blanke installation requirements.
