Frequently Asked Questions
What is a liquid membrane?
A liquid membrane is a coating applied by brush, roller, or trowel that cures into a continuous waterproof barrier. Most products in this range are Class III with more than 300 percent elongation. Apply them to concrete, masonry, fibre cement sheeting, and approved substrates.
Which liquid membrane can I tile over the fastest?
Ardex WPM 155 Rapid Plus and Gripset 38FC both allow tiling after four hours. Most other water-based membranes need 24 to 48 hours before tiling. Duram Multithane two-part systems accept foot traffic in 12 to 24 hours.
Can a liquid membrane be left exposed to sunlight?
Yes. Eight products in this range offer UV stability. Everflex WPUV and HVUV resist UV without a topcoat. Gripset P39 and Gripset Xpress Multi Pro are UV stable and accept light foot traffic. Two-part systems need a compatible topcoat for UV.
Which liquid membrane supports vehicle traffic?
Duram Multithane 2P-A80, Duram Multithane Standard, and GCP Silcor 580 support heavy foot and light vehicle traffic with their matching topcoat systems. These are the only trafficable liquid membranes. All three need a protective topcoat.
Which liquid membrane has the lowest VOC?
Everflex Aqua-Ban has less than 1 g/L VOC. Ardex WPM 130 and Gripset 38FC are water-based with low emissions. RLA Safe2O is a silyl modified polymer with Green Tag certification and is isocyanate-free. Check individual data sheets.
What is the thinnest liquid membrane I can apply?
Ardex WPM 155 Rapid Plus builds at 0.5 mm dry film thickness, the thinnest in this range. Most water-based membranes need 1.0 mm. Two-part polyurethane systems need 1.5 mm or more. Always follow the manufacturer specified thickness.
