Application Instructions:
Preparation:
The substrate must be clean and dust-free. All contaminants such as friable material, grease, and oil should be completely removed. Pre-soak the substrate but ensure that no standing water remains.
Mixing:
SpECtite WTA is a one-component cementitious adhesive. Pour the measured volume of water into an appropriately sized plastic or metal drum. The powder should be added to the water slowly whilst mixing with a spiral paddle attached to a slow-speed electric drill. Mixing should continue for a minimum of 5 minutes until a uniform, lump-free consistency is produced. Allow the product to stand for 15 minutes, then remix for 1 – 2 minutes prior to using.
Application:
Apply SpECtite WTA at a depth of 3 – 6mm into a working area not exceeding 1m². For ceramic floor tiles, decorative stone cladding, and in wet conditions in general, solid-bed fixing is recommended. In other situations, the adhesive may be combed with a notched trowel prior to fixing.
Tile Placement:
Press the dry tiles into place using a twisting action to ensure good contact with the adhesive. Tapping with a rubber hammer ensures good contact with the adhesive. Remove any excess adhesive from the surface of the tiles with a damp cloth prior to the material setting.
Curing:
Allow the SpECtite WTA to cure for a minimum of 24 hours before attempting further grouting of joints between ceramic wall/floor tiles. After fixing ceramic floor tiles, no traffic should be allowed for a minimum of 4 days at 25°C.
