Select the use of 1mm tile spacers when embarking on the installation of large format tiles, particularly in scenarios where a narrow grout line is desired. This choice ensures precision and a sleek aesthetic 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.
