In the realm of floor tile installation, adhering to the industry norm of employing 3mm tile spacers ensures a standardized approach that contributes to a well-balanced and expertly executed outcome.
Tiles undergo contraction and expansion even after being installed. Without spacing, tiles would exert pressure against each other, leading to cracks and loosening. Tile spacers ensure uniform gaps and lend a polished appearance to the completed setup. While the choice of spacer width is subjective, historically 2mm was preferred for walls and 3mm for floors.
