Duromastic ACS-2

Duromastic™ACS-2 is a two part high solids liquid / cement copolymer membrane with fibre reinforcement. Duromastic™ACS-2 cures rapidly to form a flexible waterproof lining for showers and other wet areas as described in Australian Standard AS3740:2004 “Waterproofing wet areas within residential buildings”. It complies with AS4858:2004 “Wet Area Membranes”. ACS-2 is particularly suitable for applications where polymer modified render will be applied or in conditions where other waterbased waterproofing products have difficulty in drying due to excesive humidity and coolness.
DUROMASTIC™ACS-2 forms a waterproof lining to most building materials including reinforced concrete, cement render, water resistant plaster board, and compressed cement sheeting etc. The surface must be fixed according to manufacturers directions and must be clean and dry. DUROMASTIC™ACS-2 is suitable for external use on light pedestrian trafficable decks, parapets and flashings. Top coat with Duroarmor™ for UV resistance.
