4. Usage Mix with clean water approx 7 to 8 litre , apply the adhesive adhesive at a minimum thickness thickness of of 9mm, use a suitable 12mm half round notched trowel; for minimum thickness 6mm, use a suitable 9mm notched trowel or minimum thickness 3mm use a suitable 6mm notched trowel. Do not spread more than 1 sq. meter at a time. IMPORTANT: Due to atmospheric condition, the skinover of the adhesive will occur after 5-10 minutes, therefore special attention have to be taken. So it is important that adhesive is applied in a small area that can be covered with tiles within this period of time.

To break the skin re-trowels in opposite direction. Fix stone, ceramic glazed tiles, ceramic vitrified tiles, mosaic within 15 minutes of applying adhesive and check coverage by occasionally lifting stone, ceramic glazed tiles, ceramic vitrified tiles, mosaic. Allow 24 hours before grouting. 5. Coverage A- Approx 10 m² to receive receive ceramic tile / mosaic on flat surface at 3mm bed thickness using using notched trowel B- Approx 5m² to receive ceramic tile on flat surface surface at 6mm bed thickness using notched trowel C- Approx 2.5m² to receive stone / ceramic tile on flat surface at at 9mm bed thickness thickness using notched trowel 6. Surface / Preparations All surfaces must be structurally sound, clean, and free of dust, grease, oil, compound and any foreign material which will inhibit proper bond. Concrete should have a surface to the similar to a light broom finish.
