Application guide

- Spread adhesive with a suitable notch trowel at about 60 degrees and comb in one direction.
- Press tiles firmly into the ribs and slide across the rib direction to collapse the ribs and remove voids.
- Back butter large format tiles if required to achieve full coverage.
- Clean excess adhesive from joints and tile faces with a damp sponge while wet.
