How to use

Prepare the area. Surface must be clean, dry, sound, and free of dust, oils, and loose material. Prime as required by your chosen waterproofing membrane system.
Measure and cut lengths to suit corners, junctions, and penetrations. Pre fit to check placement.
Bed the tape into the first wet coat of compatible membrane or approved adhesive. Press firmly to remove air pockets and ensure full contact.
Overlap joins by at least 50 mm. At corners, mitre or fold neatly so the tape remains flat without creases that could trap water.
Topcoat with additional coats of membrane to fully encapsulate the tape, observing required dry times between coats.
Cure the membrane system as directed before tiling or finishing.

Good to know

Cover the tape with a compatible liquid membrane. Do not leave exposed to prolonged UV.
Always follow the membrane manufacturer instructions for primers, coat thickness, and cure times.
If in doubt about compatibility, perform a small adhesion test on your substrate and membrane.

Storage and safety

Store in a cool, dry place away from direct sunlight.
Wear gloves and eye protection during surface prep and membrane application.
Dispose of offcuts and packaging according to local regulations.
