Why Do Tiles Need Spacing? Is It Just for Grout Sealing?
Tile spacing (2-3mm gaps) is essential to prevent cracking from heat expansion, hide size/installation errors, and simplify repairs. While gaps exist regardless, grout sealing enhances aesthetics and durability.
Key Reasons for Tile Spacing:
Heat Expansion & Contraction
Tiles and cement expand/contract with temperature changes. Gaps prevent tiles from cracking or bulging (like buckling floorboards).
Tile Size Variations
Machine-made tiles have tiny size differences. Spacing hides uneven edges for a smooth look.
Installation Imperfections
Even skilled tilers can’t place tiles perfectly. Gaps avoid highlighting alignment issues.
Easy Repairs
Damaged tiles can be replaced without disturbing neighbors if gaps exist.
Grout Sealing: More Than Beauty
Gaps will exist—grout sealing makes them durable and attractive.
Use polymer-based grout to waterproof gaps and stop mold.
Pro tip: Request 2-3mm gaps during tiling for easier sealing later.
Summary:
Tile spacing (2-3mm gaps) is essential to prevent cracking from heat expansion, hide size/installation errors, and simplify repairs. While gaps exist regardless, grout sealing enhances aesthetics and durability.
