Tech data sheet: broken link removed
1. Ensure that you have the appropriate tools andsufficient ARDEX WPC to cover the intended area.
For coverage information refer to the technical data
overleaf. The surface to be tiled must be dry, rigid, of
sufficient strength and free from dust, grease, dirt, etc.
Apply at temperatures above 5°C
2. Mix a small amount of ARDEX WPC
to a slump free consistency for filling
holes, gaps, joints etc. For application by spatula, pallet
knife or towel, mix approximately 1.75kg ARDEX WPC
liquid with 2.5kg ARDEX WPC powder per m2
at 3mm
thickness, i.e 4.25kg of Mix No.1 per m2
at 3mm.
The working time is approximately 45 minutes at 20°C.
3. Reinforce joints that tend to crack with the ARDEX
self adhesive mesh scrim. Apply the mixed ARDEX
WPC (MIX No.1) with a spatula, pallet knife or trowel to
seal joints in corners and fill holes and gaps around pipes,
etc. N.B. The mesh scrim should be applied prior to the
application of Mix No.1.
4. Mix approximately 0.75kg ARDEX WPC
liquid with 0.75kg ARDEX WPC powder
per m2
at 0.8mm thickness to obtain a flowing consistency.
Apply this Mix No.2 evenly with a brush or paint roller to
cover the surface with a uniform coat. A second coat
should be applied approximately 1 hour after the first to
obtain an effective waterproof protection layer of at least
0.8mm thickness. ARDEX WPC will dry to a dark brown
flexible coating
5. Ceramic tiles etc, can be fixed onto the second coat
of ARDEX WPC after approximately 2 hours
