Application guidance
Ensure the substrate is sound, clean and free from dust, loose particles, oil, grease and other contaminants that may affect adhesion. Mix one 25 kg bag with approximately 7.25–7.5 litres of clean water using a low-speed electric mixer at a maximum of 500 rpm until a smooth, lump-free consistency is achieved. Allow the mixed adhesive to stand for approximately 5 minutes, then briefly remix before application. Apply at 1.5–5 mm thickness using an appropriate notched trowel. Spread only as much adhesive as can be tiled within the available open time. Press tiles firmly into the fresh adhesive with a twisting action. For tiles larger than 300 × 300 mm or applications requiring higher performance, use the back-buttering technique.
Coverage
Approx. 5–7 m² per 25 kg bag, depending on substrate profile, surface roughness, tile size and application technique.
