Henkel Polybit Watertite WA11

Watertite WA 11 system is a composite waterproofing membrane and tile finish system, which is designed for rigid concrete surfaces in indoor conditions and which are exposed to moderate water splashes without hydrostatic pressure. Designed to be used in concrete floors and walls in domestic showers, toilets and kitchens classified as rigid surfaces, which are subjected to occasional or brief exposures to water splashes. The water exposure of such areas is categorized as moderate without hydrostatic pressure in indoor conditions.

Fields of application: indoor concrete floors and walls in domestic showers, toilets and kitchens classified as rigid surfaces, which are are subjected to occasional or brief exposures to water splashes.

สเปคสินค้า

Characteristics:
- Good flexibility
- Thermal co-efficient of expansion similar to that of concrete
- Good adhesion to both porous and non-porous surfaces
- Good mechanical properties
- For ceramic tiles (glazed & terracotta), vitrified tiles, porcelain tiles, mosaic tiles and natural stones like granite, sandstone
- Easy workability
- Crack resistance
- Smooth surface finish
- Anti fungal/Anti bacterial
Components:
1. Polyflex - A two component polymer mortar composite flexible water proofing slurry is applied at a minimum thickness of 2mm in two coats on the concrete surface to protect the underlying screed against moisture penetration.
2. Watertite CL 252 - Non-woven sealing tape applied in all corners, joints, edges, floor drains and other penetrations.
3. Ceresit CM11 - Universal polymer modified cementitious tile adhesive with very low emissions for indoor and outdoor areas.
4. Ceresit CE33 - cement-based tile grout for filling joints in floor & wall of ceramic, porcelain, mosaic, natural stone, marble & granite indoor and outdoor areas. For joints between 1 and 8mm wide.
