Tile spacers are small pieces of plastic that are placed in between tiles when laying a tile floor, to provide proper spacing for grouting. Tile spacers come in a range of sizes, depending on the width you want for your grout lines. These spacers help you achieve 2mm space in between tiles. They are like a plus sign 3mm and come with a pack of 250 pcs. Additional spacers can be used in conjunction with tiles if you wish to increase the spacing between tiles.
