Essential Checklist+−
Complete these critical checks before approving the work or proceeding to the next construction stage.
✓16 Inspection Points
✓4 Verification Categories
✓Area and Joint Dimensions+-
- Tile area was measured on site after tiling was complete — not calculated from room dimensions alone.
- Joint width was measured on the actual laid tiles — not assumed from the tile specification sheet.
- Tile thickness was measured from the actual tile — manufacturer's nominal thickness can vary by 0.5–1mm.
- Floor and wall areas with different joint widths or tile sizes were calculated separately.
- Dimensions were entered in consistent units.
✓Grout Type Selection+-
- Grout type is appropriate for the joint width — unsanded grout for joints under 3mm, sanded grout for joints 3–12mm.
- Epoxy grout is specified for wet areas, chemical exposure, food preparation areas, and joints under 3mm where high hygiene is required.
- Cement-based grout is not used in joints narrower than 1.5mm — it cannot be packed in and will crack.
- Movement joints (expansion joints) were specified at perimeter, columns, and over structural joints — these are not filled with grout.
✓Coverage and Mixing+-
- Coverage rate used in the calculation matches the grout manufacturer's data sheet for the specific joint width and tile size.
- Water ratio follows the manufacturer's specification — adding extra water weakens grout and causes colour variation.
- Tiles were cleaned of adhesive and dust from joints before grouting — residue prevents grout from bonding to joint edges.
- Tile adhesive was fully cured before grouting commenced — minimum 24 hours for standard adhesive, 48 hours in cold or humid conditions.
✓Wastage and Purchase+-
- Wastage of 10–15% was applied to the calculated grout quantity for mixing residue, application waste, and bag variation.
- All grout was ordered from the same production batch — different batches of the same colour can vary visibly.
- The final quantity including wastage was used for purchase.

✓Area and Joint Dimensions+-
- Tile area was measured on site after tiling was complete — not calculated from room dimensions alone.
- Joint width was measured on the actual laid tiles — not assumed from the tile specification sheet.
- Joint width is consistent across the floor or wall — variable joint widths were averaged or calculated in sections.
- Tile thickness was measured from the actual tile — manufacturer's nominal thickness can vary by 0.5–1mm.
- Floor and wall areas with different joint widths or tile sizes were calculated separately.
- Dimensions were entered in consistent units.
✓Grout Type Selection+-
- Grout type is appropriate for the joint width — unsanded grout for joints under 3mm, sanded grout for joints 3–12mm.
- Epoxy grout is specified for wet areas, chemical exposure, food preparation areas, and joints under 3mm where high hygiene is required.
- Cement-based grout is not used in joints narrower than 1.5mm — it cannot be packed in and will crack.
- Colour-matched grout was selected before tiling started — matching grout colour to existing laid tiles post-installation is unreliable.
- Anti-fungal grout is specified for bathrooms, wet rooms, and areas with persistent moisture.
- Movement joints (expansion joints) were specified at perimeter, columns, and over structural joints — these are not filled with grout.
✓Coverage and Mixing+-
- Coverage rate used in the calculation matches the grout manufacturer's data sheet for the specific joint width and tile size.
- Grout was mixed in small batches — only as much as can be applied and cleaned in 20–30 minutes.
- Water ratio follows the manufacturer's specification — adding extra water weakens grout and causes colour variation.
- Tiles were cleaned of adhesive and dust from joints before grouting — residue prevents grout from bonding to joint edges.
- Tile adhesive was fully cured before grouting commenced — minimum 24 hours for standard adhesive, 48 hours in cold or humid conditions.
✓Wastage and Purchase+-
- Wastage of 10–15% was applied to the calculated grout quantity for mixing residue, application waste, and bag variation.
- All grout was ordered from the same production batch — different batches of the same colour can vary visibly.
- Sufficient grout for a test area was set aside and cured before ordering the full quantity — confirms colour match.
- Grout sealer requirement was confirmed — unglazed tiles and natural stone need sealing before grouting to prevent staining.
- The final quantity including wastage was used for purchase.
