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.4.75 to 6.0 litres of water are required for each 25kg bag of SpECtite WTA depending on the consistency required.

Generally, the lower water addition would be used for vertical application and the higher water addition for horizontal application.

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. 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.

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.

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 @ 25°C.

SpECtite WTA is supplied in 25kg packs, each pack produces approximately 15.5 litres of mixed material, but will depend on the water addition used.
