Using dragon skin anti fracture membrane under your tile or stone can make all the difference in a lasting installation.

Installing an anti fracture membrane and waterproofing skin over your sub floor can make all the difference in the world to a lasting tile floor installation.

At California Flooring Service we use Dragon Skin from Siena. Below I will discuss a little bit about the anti fracture/waterproofing product.

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).

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.

So, before having your tile or stone installed ask your contractor about this product. this can really make a difference to promoting the integrity of the installation.
