Ensure all surfaces to be coated are clean, sound and free of dust. The surface to be coated should be reasonably even so a uniform thickness can be applied. Westox CR-25/ Cement can be used to even the surface prior to the application of the Wet Area Membrane.
Westox Wet Area Membrane can be applied to damp substrates provide there is no free water present. If in doubt, pre prime with Westox CR-25 / Cement or Westox WB30 Epoxy allowing a minimum of 4 hours drying before applying the Westox Wet Area Membrane. Consult our Technical Department if you require further advice.
Apply Wet Area Membrane in 2 coats at approximately 500ml/600g per m2 (600 micro WFT) Allow a minimum of 4 hours and a maximum of 24 hours between coats. The finishing dry firm thickness (DFT) should not be less than 600microns. Reinforcement with Westox Polymesh is recommended at wall and floor junction. Allow a minimum of 4 days cure carrying out ponding tests or tiling. (Longer at low temperatures).
- Westox Wet Area Membrane is not suitable for use over expanded Polystyrene.
- Do not apply at surface or air temperature below 7ºc.
- Do not apply externally if wet weather is imminent.
CLEAN UP & PACKAGING
Wash all tools and containers in water immediately after use.
Container Size: 15 Litre containers.
The Westox Area Membrane contains no solvents and is considered non toxic, however normal hygiene practice should be observed and protective clothing should be worn to prevent prolonged skin contact.
