Good practice
- Old tiles come up so the new floor bonds to a sound base
- Large format: flat to 3 mm under 2 m, back-buttered, clips, and two people to lift
- Diagonal and herringbone waste about 15%
- Natural stone: white adhesive, back-butter, seal before grouting and again after
- Mosaic runs at 5–10 m² a day and uses about 1 kg/m² of grout
- Underfloor heating: S1 adhesive, decoupling and movement joints
- 600×600 and bigger: levelling clips stop lipping (about 11 per m²)
