Frequently Asked Questions About Everflex WPUV
Q: Is Everflex WPUV suitable for external use?
A: Yes, Everflex WPUV is specifically formulated for UV exposed applications and is suitable for both internal and external use.
Q: Do I need to prime the surface before applying Everflex WPUV?
A: Priming is always recommended, especially on porous and warm surfaces. Use Everflex WBP for internal applications and Everflex VBS for external applications.
Q: What is the minimum dry film thickness required?
A: A minimum of two coats is required to achieve a minimum dry film thickness (DFT) of 1mm.
Q: How long does Everflex WPUV take to cure?
A: Allow approximately 48 hours of cure time at 25°C and 50% humidity before tiling. Cure times vary depending on atmospheric conditions and substrate porosity.
Q: Can I tile directly over Everflex WPUV?
A: Yes, Everflex WPUV is a tile adhesive friendly membrane. RLA and Gripset have confirmed suitability of specific adhesives. Confirm suitability with the adhesive manufacturer.
Q: What are the limitations of Everflex WPUV?
A: Do not apply below 10°C or above 35°C, on damp or contaminated surfaces, or in areas subject to negative hydrostatic pressure or rising damp. It is designed for maintenance foot traffic only.
