Wear-resistant, Recyclable. Easy to use in DIY operation. Balance tiles in the same horizontal position. Improve the installation speed of tile. Reduce the fatigue/pressure of installers. There is hardly any crackless, flat surface. It reduces the need for grinding and polishing. Prevent tiles from moving during solidification. Scope of application: masonry Applicable Brick space: 2-6mm/0.08-0.24inch Applicable Tile Thickness: 3-16mm/0.12-0.63inch Use Tips: Lay the first tile, leaving more than 2mm (with gaskets). Close to tile. Insert T-pins along the space between tiles. Then rotate 180 degrees and the T-needle is stuck at the bottom of the two tiles. Adjust the lid with a hand/special wrench until the two tiles are on the same level.
