Frequently asked questions
-
What substrates does ACTFLEX 101 UV bond to?
Compatibility101 UV bonds to concrete, render, fibre-cement, plasterboard, and masonry over an appropriate primer. Designed for exposed roofs, gutters, and exterior walls where UV resistance is required.
-
How is it different from other ACTFLEX membranes?
Performance101 UV is a UV-stabilised copolymer formulated specifically for permanent UV exposure - it resists chalking and re-emulsification that affects standard membranes under sun exposure. 450% elongation, low VOC.
-
How many coats and thickness?
InstallationApply three coats at approximately 1.2mm total DFT. Use 0.8mm DFT on walls and 1.2mm DFT on roof areas. Coverage is 8-10 m² per 15L. Trafficable in 24 hours.
-
Standards compliance?
ComplianceClass III certified per AS/NZS 4858 and meets AS4654.1 for external waterproofing. The UV stability makes it the recommended membrane where direct sun exposure cannot be avoided.
-
What's the application temperature range?
PerformanceApply between 10°C and 26°C ambient. Tack-free in 6 hours, full cure in 14 days. Avoid application in direct sun on hot substrates - schedule for cool morning or shaded conditions.
