Why large tiles need a specialist
The bigger the tile, the less forgiving it is. A floor that's slightly uneven is invisible under a 12×24 tile but shows up as lippage (one edge higher than the next) under a 24×48. Large tiles are also heavier, can bow slightly, and need full contact with the mortar to avoid hollow spots and cracks.
How we install large-format tile
- Flat substrate first. Floors are checked with a long straightedge and corrected with self-levelling compound where needed. Walls are straightened before board goes up.
- The right mortar. Large and heavy tile (LHT) mortar, mixed to the right consistency.
- Full coverage. Mortar on the floor and back-buttering on the tile, so there are no hollow spots under the corners.
- Levelling systems. Clips and wedges hold neighbouring tiles flush while the mortar sets.
- Planned layout. With big tiles, a bad cut is very visible. The layout is set out before the first tile goes down.
- Careful handling. Large tiles are moved and set with suction cups and the right tools to avoid cracks.
Where large-format works well
Open-plan floors, hallways, kitchens, shower walls with fewer joints, feature walls and fireplace surrounds. Marble-look and concrete-look porcelain in 24×48 is one of the most requested finishes in GTA bathrooms right now.
Price
Large-format floors typically run from $13 to $20 per sq ft in labour, more on walls and where heavy levelling is needed. See the price guide for details.
