What are the professional ceramic and porcelain spacers? They are divided into two parts: 1- The white spacer: used only once 2- The red wedge: can be used an unlimited number of times. The spacers come packed in separate bags according to color. White spacer bag packing: 100 pieces in the bag. Method of use: During installation, the white spacers are placed at the corners of the tiles and on their edges under the tiles at the end of the tile, and the second piece is placed beside it, then the wedge is pressed with the dedicated tool until the edges are equal and the curvature is reduced, and the process is repeated for all pieces. Leave until the second day, then the wedges are removed by striking them with a wooden or rubber hammer. The white part separated from inside the red wedge is removed so it can be used again.
