USE
ARDEX WPC and ARDEX WPC W are used to waterproof backgrounds such as cement or gypsum plaster, plasterboard or wood-based materials prior to fixing tiles in domestic or commercial kitchens, showers and bathrooms.
NOTE: The use of timber-based sheets and boards should be avoided if at all possible in wet locations. Ideally, they should be replaced or oversheeted with plasterboard prior to applying ARDEX WPC or ARDEX WPC W. Timber-based sheets or boards are not recommended for use in commercial showers etc.
NOTE: Concrete floors and cement/sand screeds may also be protected from the ingress of surface water by the application of ARDEX WPC.
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 or ARDEX WPC W Liquid to 1 part ARDEX WPC or ARDEX WPC W 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 or ARDEX WPC W Liquid to 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 be shortened at high temperatures and extended at low temperatures.
Once the mixed material begins to set and thicken, discard the material and do not add extra ARDEX WPC Liquid.
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.
