Custom lengths are often available. The above are typical data for the testing sample rolls.

Physical performance

Code compliance：ANSI A118.10, American National Standard Specification for Load Bearing, Bonded, Waterproof Membrane for Thin-Set Ceramic Tile and Dimension Stone Installation.

Installation Instructions

Surface preparation:

Ensure the substrate is clean, even, loading bearing and free from debris. The surface should be level and smooth to ensure proper adhesion.

Apply thin-set mortar and membrane:

The GardMem membrane is adhered to the substrate with thin-set mortar. Apply the thin-set mortar to the substrate with a 1/4" x 3/16" (6×5mm) V-notched trowel, then press the membrane onto the mortar with the flat side of trowel to eliminate air pockets.

Seaming & overlaps:

Seams should be constructed by overlapping the edges of at least 2" (5 cm) using ANSI A118.4 compliant thin-set mortar, or by abutting the edges and covering the joints with GardMem-BAND.

For inside and outside corners, adhere preformed corner sections (GardMem-IC, GardMem-OC).

For wall and floor connections, use GardMem-BAND.

Install GardMem-PS pipe seals at showerhead, body spray, and GardMem-VS at the mixing valve.

GardMem membrane should be separated at existing expansion, structural and flexible edge joints. Cover the joints with GardMem-FlexBAND. To allow for greater movement, the center section of the GardMem-FlexBAND can be tucked into the cavity of the expansion joints.

Flood testing of the waterproofing system: Prior to setting tile, wait for 24 hours to allow for final set of the mortar before testing to ensure waterproofing performance of the whole system.

Tile Installation: Once the membrane is installed, tiles can be applied directly to the exposed membrane surface with thin-set mortar.

Storage

Follow a two-year shelf life and use it on a first-in, first-out basis.

Store in a well-ventilated, dry area, away from sunlight and rain. The storage temperature should not exceed 120℉.

Keep off the ground under tarps or other protective coverings to prevent exposure to rain and ground moisture.

Avoid prolonged exposure to direct sunlight.
