Waterproofing Membrane - Blanke Aqua Shield

Size *

Blanke Aqua Shield is a fabric membrane, used for tile showers, that is 100% waterproof. Aqua Shield is applied to the surface substrate with a thin bed of a modified thinset. Ceramic or natural stone tiles can then be directly installed onto the Aqua Shield using the same modified thinset. Once installed, Aqua Shield provides a vapor barrier that makes it ideal for steam rooms and showers. The high tensile strength of the Blanke Aqua Shield ensures a long lasting protection from moisture penetration in continuous wet areas such as shower stalls and bathrooms. In addition to waterproofing, the Blanke AQUA SHIELD engineered blend of fibers also provide exceptional resistance to mold build-up; break-down from strong chemicals; and UV destabilization.


Check substrate to ensure that it is dry, even and sound. Apply a setting adhesive suitable for the application to the wall or floor substrate with a 4 mm notched trowel. Apply the adhesive on an area approximately 3/8“ wider than the Aqua Shield fabric. Cut the fabric to the desired length and place on the substrate in the same manner as when hanging wall paper and smooth out with a wall paper brush (tampico brush). Use a wide flat trowel to carefully embed the fabric into the adhesive ensuring there are no air pockets. Allow at least a 1/4“ fabric overlap. The tiles can then be installed immediately onto the Aqua Shield in the normal manner.

Aqua Shield can be installed using a 1/4" x 3/16" V-notched trowel.
