During tile bonding, the installer may encounter various problems, such as uneven "alpha-diasis" on the surface. This can occur either due to the nature of the surface or from an incorrect amount of adhesive applied to the tiles, resulting in some tiles being a few millimeters higher in certain areas. To prevent installation errors, there are specific products that are essential for proper tile alignment, especially for large-format tiles. - Joint Thickness: 3.0 mm - Tile Thickness: 8-14 mm They help the installer save time by adjusting the height of the tiles and keep their edges aligned during installation. They also allow for the placement of tiles with the same joint width across the entire surface, avoiding any discrepancies in a single joint. A Spacer for Alpha-diasis is required. Packaging: 100 pieces. They can be combined with crosses or T-shapes to create thicker joints.
