Waterproofing Membrane - Blanke Aqua Shield

Size *


Blanke Aqua Shield Waterproofing Membrane is a fabric tile underlayment that can be installed with thinset to most dry, flat, and structurally sound surfaces using a 4 millimeter notched trowel. Blanke Aqua Shield's high tensile strength provides a vapor barrier to protect consistently wet areas such as steam rooms, saunas, showers, and bathrooms. The material is made up of a blend of fibers that resists mold, mildew, and break down from strong chemicals and UV destabilization. After the Aqua Shield is installed the tile is installed directly on top of the membrane using a modified- thinset mortar.

One a flat, dry, and structurally sound surface, using a 4 mm notched trowel, spread your thinset adhesive on an area approximately 3/8" wider than the fabric being laid down. With the fabric cut to your desired length, flatten the material over the adhesive like you would when applying wallpaper. Then, smooth out the fabric with a wide, flat blade trowel. This will embed the fabric into the thinset, ensuring there are no air pockets behind the membrane. Overlap different sheets of Aqua Shield by at least 1/4".
