Installation Guidance
-
Surface Prep:
Ensure all surfaces are clean, dry, dust-free, and primed if required. For porous substrates (e.g. plasterboard), we recommend using AquaTank Pro-Tile Primer beforehand. -
Apply Tape:
Peel off the release liner progressively and press the tape firmly into place along corners, joints, or penetrations. Smooth out with a roller or flat edge to eliminate air bubbles. -
Overlap Joints:
When using multiple lengths, ensure a minimum 50mm overlap to maintain waterproof integrity. -
Finish With Membrane:
Overcoat with AquaTank Neo-Flex Membrane, ensuring full coverage over the tape and surrounding area.
