ARDEX WPC is designed for waterproofing various backgrounds, including cement and sand render, gypsum plaster, and plasterboard, before tiling in both domestic and commercial settings such as kitchens, showers, and bathrooms.

Surface Preparation

Ensure surfaces are dry, solid, and free from oil, dust, dirt, or any other materials that could impede adhesion. Gypsum plaster must be fully dry and strong enough to support the weight of the tiling. Any boarded surfaces should be capable of bearing the tiles and must be securely fixed with closely spaced screws, adhering to the relevant BS 5385 standards.

Note: Moisture-sensitive backgrounds should be protected from moisture ingress. External walls should either be of cavity construction or have appropriate protection to prevent moisture from penetrating through.

Mixing

Mix One: For a trowelable paste used to seal internal corners, fill holes, and plug joints around pipes, baths, and showers, mix 0.7 parts ARDEX WPC or ARDEX WPC W Liquid with 1 part ARDEX WPC or ARDEX WPC W Powder by weight.

Mix Two: For a flowing consistency suitable for application with a brush or roller, mix 1 part ARDEX WPC or ARDEX WPC W Liquid with 1 part ARDEX WPC or ARDEX WPC W Powder by weight. The mixed ARDEX WPC or ARDEX WPC W has a pot life of approximately 45 minutes at 20°C; this time will vary with temperature, being shorter in higher temperatures and longer in lower ones.

Technical Data: Once the mixed material starts to set and thicken, discard it and do not add more ARDEX WPC Liquid to it.

Application

• Mix One: Apply using a spatula, pallet knife, or trowel to seal joints in corners and fill gaps around fixtures, pipes, etc. For areas prone to cracking, reinforce with ARDEX Mesh Scrim Tape before applying Mix One. To fill uneven areas, apply a single layer of Mix One, at least 3mm thick, to achieve effective waterproofing; no additional overcoating with Mix Two is necessary.
• Mix Two: Use for complete surface coating. Apply evenly with a brush or roller, ensuring thorough coverage, especially in corners. A second coat is needed to achieve effective waterproofing, with a total thickness of at least 0.8mm. Apply the second coat about 30 minutes after the first. Ceramic tiles or mosaics can be fixed onto the second coat after approximately 1 hour at 20°C; drying times will vary with temperature. Do not apply ARDEX WPC or ARDEX WPC W at temperatures below 5°C.
