The Miracle Sealants Levolution Flat Spacer is a tile spacer designed to provide precise spacing and leveling for your tile installation. The flat spacers are to be used along the perimeter/wall of the installation. These spacers are available in 3 sizes ( 1/16", 1/8", 3/16") and are compatible any tile up to 1/2" thick. Once the mortar is dry the spacer can be completely removed so nothing is left behind in the grout joint. Spacers are sold 50 pieces per bag.
