Application
Surface preparation
Ensure the surface is solid, clean and stable, free from oil, grease, paint, mould release agents or curing compounds. Dampen the surface a few hours before applying the adhesive for optimal results.
Mixing
Mix each 25 kg bag of CASTECH Tile GP with 4 – 5 litres of clean water until a smooth, lump-free consistency is achieved. Allow the mixture to rest for 10 minutes, then stir again before application. A low-speed electric drill with a paddle attachment is recommended.
Application
Spread the adhesive evenly on the surface to a thickness of 3 – 4 mm, then comb it horizontally. Press each tile firmly into the adhesive bed with a slight twisting motion to ensure good contact. Apply the adhesive to no more than one square metre at a time to avoid premature drying. Joint spacing: leave a minimum spacing of 2 mm around each ceramic tile for improved flexibility and stability. Finishing: wipe away excess adhesive with a damp cloth before it sets. Grouting can be carried out after 24 hours.
Curing
24 hours with clean water.
Packaging & storage
