Ardex WPC Waterproof Protection Coat 10kg

Description ARDEX WPC Waterproof Protection Coat is a cement-based, rapid drying, waterproof coating that allows tiling to commence after just 90 minutes. With an adjustable mix ratio, ARDEX WPC Waterproof Protection Coat can be used to fill holes, gaps, and joints, as well as for general waterproofing application. ARDEX WPC Waterproof Protection Coat is used to waterproof backgrounds such as cement and sand render, gypsum plaster, or plasterboard prior to fixing tiles in domestic or commercial kitchens, showers, and bathrooms. Note: BS 5385-1 advises that plywood and other wood-based sheets or boards should not be used for direct tiling. Timber-based sheets should be replaced or oversheeted with plasterboard, or suitable tile backer board, prior to applying ARDEX WPC Waterproof Protection Coat. Once the mixed material begins to set and thicken, discard the material and do not add extra ARDEX WPC Waterproof Protection Coat Liquid. Concrete floors and cement screeds may also be protected from the ingress of surface water by the application of ARDEX WPC Waterproof Protection Coat. Application: Use Mix One for application with a spatula, pallet knife, or trowel for sealing joints in corners and filling holes and gaps around fixtures, pipes, etc., prior to applying two coats of Mix Two. Where joints tend to crack, they should be reinforced with ARDEX Mesh Scrim Tape prior to applying Mix One. To fill uneven areas with a trowel, a single application of Mix One, at least 3mm thick, is required to obtain an effective waterproof protection coat (no overcoating with Mix Two is necessary). Mix Two should be used to give a complete coating on the surface, applying it evenly with a paint brush or roller, and working the material well into the corners with a brush. To obtain an effective waterproof protection layer, a second coat will be necessary and the total thickness should be at least 0.8mm. The second coat of Mix Two can be applied approximately 30 minutes after the first coat. Ceramic tiles, mosaics, etc., can be fixed onto the second coat after approximately 1 hour at 20°C. The drying time will be shortened at high temperatures and extended at low temperatures. Do not apply ARDEX WPC Waterproof Protection Coat at temperatures below 5°C. Preparation: Surfaces must be dry, rigid, sound, and free of oil, dust, dirt, or other barriers to adhesion. Gypsum plaster must be dry and of adequate strength to support the weight of the tiling. Any boarded background must be able to support the tiles and be rigidly and securely fixed with closely spaced screws to comply with the appropriate BS 5385 requirement. Note: Moisture-sensitive backgrounds should be protected from moisture ingress from behind, i.e., external walls should be of a cavity type or suitably protected solid single skin construction. Mixing: Mix One: A slump-free, trowelable paste to seal internal corners between walls, fill holes, and plug joints and gaps around pipes, baths, and showers is produced by mixing the two components in the ratio of 0.7 parts ARDEX WPC Waterproof Protection Coat Liquid to 1 part ARDEX WPC Waterproof Protection Coat Powder by weight. Mix Two: A flowing consistency for application by brush or paint roller is produced by mixing the two components in the ratio of 1 part ARDEX WPC Waterproof Protection Coat Liquid to 1 part ARDEX WPC Waterproof Protection Coat Powder by weight. The mixed ARDEX WPC Waterproof Protection Coat has a pot life of approximately 45 minutes at 20°C. This time will be shortened at high temperatures and extended at low temperatures. Tile Fixing: Tiles can be fixed with an ARDEX Cement-Based Tile Adhesive e.g., ARDEX X 325 PTB, ARDEX MICROTEC X 77, or ARDEX MICROTEC X 78, and grouted with ARDEX-FLEX Flexible Tile Grout. Alternatively, for areas where chemical resistance and hygienic joints are required, ARDEX EG18 PLUS Easy to Apply and Clean Epoxy Tile Grout should be used. Packaging: ARDEX WPC Waterproof Protection Coat Liquid is packaged in polyethylene containers – net weight 5kg. ARDEX WPC Waterproof Protection Coat Powder is packaged in paper sacks incorporating a polyethylene liner – net weight 5kg.
