Frequently Asked Questions
What do I need to waterproof a wet area?
Use a compatible primer, waterproof membrane, detail parts for corners and junctions, and a floor waste or linear drain. Prepare the substrate first. Follow the membrane maker's system instructions for each layer.
Is waterproofing the same as tanking?
Tanking is the waterproof layer installed under tiles in a shower or bathroom. Waterproofing also covers roofs, basements and retaining walls. The membrane must suit the exposure and the substrate.
Do I prime before applying a waterproof membrane?
Yes, when the membrane system requires it. Use a primer for the substrate, such as porous, non-porous or moisture-barrier grade. Check the membrane maker's primer schedule before application.
What is the difference between a liquid and a sheet membrane?
Liquid membranes cure in place and suit complex shapes, corners and penetrations. Sheet membranes are pre-formed and bonded or welded to the substrate. Choose the system for the substrate, exposure and site details.
Can I tile over a wet waterproof membrane?
No. Let the membrane cure fully before you install the approved tile adhesive. Tiling over a wet or tacky membrane can weaken the bond and damage the waterproof layer.
