A. Clean out the crack of any loose dust and debris using a stiff bristle brush or by blowing air into the crack.
B. Blend the resin materials to match the color matrix, adding pigment as required.
C. Following manufacturer's instructions, force mixed resin into the void using re-pointing tools or a caulking gun, making sure it is pressured into the crack as deep as possible. Fill until flush with the surface. Sometimes, the supplier will instruct using a primer for their materials.
D. Touch-up repaired surface with enamel to match color of tile.
E. Do not extend patch material into the grout or mortar joint. Crack repairs should be limited to individual tiles.
