Siena Dragon Skin is a premium, ready to use waterproofing and anti-fracture membrane, manufactured with a mixture of latex polymers and other proprietary additives to produce a high quality elastomeric barrier. Dragon Skin is easily applied using a trowel, a roller, paint brush or a sprayer. Dragon Skin is a light purple color when wet, and changes to a dark purple color to indicate when it is dry. Dragon Skin bonds to most surfaces, dries quickly and is ready to flood test in as little as 24 hours. Dragon Skin exceeds the requirements for ANSI A118.10 for waterproofing membranes and ANSI A118.12 for crack isolation. It can be use in residential, commercial, interior and exterior tile and stone installations. IAPMO has listed Siena Dragon Skin for use as a shower pan liner (IAPMO R&T, File # 6892).
Basic Uses
Dragon Skin is used on recommended substrates as a barrier to water migration for load bearing thin set tile and stone installation, and as a crack isolation membrane used to prevent shrinkage or on-structural cracks up to 1/8” transmitting from the substrate through to the finished goods. Use polymer modified mortars meeting ANSI A118.4 or A118.11 for tile or stone installation over membrane.
