Reduce the fatigue/stress of the installer. Almost no lip slip, flat surface. Reduce the need for grinding and polishing. Prevent the tiles from moving during curing. Use suggestions: 1. Lay the first tile, leaving a distance of more than 2mm (used with cross spacers). Close to the tiles. 2. Insert the T-shaped needle along the gap of the tile. 3. Then rotate 90 to clamp the T-shaped needle at the bottom of the two tiles. 4. Use your hand/special wrench to adjust the cover until both tiles are on the same level. 5.
