What is a tile spacer?
A tile spacer is a small cross-shaped piece of plastic placed between tiles to keep every joint the same width. Tile spacers come in different thicknesses, for example 2, 3, 4 and 5 mm. The thickness of the spacer determines the width of the joint.
Types
- Crosses: for the junctions of four tiles in a straight (stack or grid) layout.
- T-spacers: for brick-bond or random layouts where three tiles meet.
- Wedges: to take up small differences in height or size, for example under the bottom row of wall tiles.
- Levelling systems: clips with wedges or screw caps that not only space the tiles but also pull them flush with each other. Especially useful for large-format tiles, where lippage quickly shows.
Which joint width?
First of all, follow the tile manufacturer’s advice. As a rule of thumb:
- Rectified (precision-cut) tiles can be laid with a narrow joint.
- Non-rectified tiles have small size variations; a wider joint absorbs them.
- Floors usually get a slightly wider joint than walls.
Tips
- Spacers can be laid flat at the junction or upright (with one leg in the joint). Upright, they are easier to remove.
- Remove the spacers before grouting unless the manufacturer says they can stay in. Spacers left in give a thinner grout line and can show through.
- Despite the spacers, check every few rows with a level or laser: spacers control spacing, not alignment.
