Can I re-grout with LATICRETE SpectraLOCK PRO Grout?
Yes! For existing grout joints which have deteriorated or discolored, LATICRETE SpectraLOCK PRO Grout is excellent for re-grouting. The existing grout must be removed mechanically to a minimum of half the depth of the tile. Use a grout removal tool, saw, or high-pressure water jet, then re-grout following the LATICRETE SpectraLOCK PRO Grout installation instructions.
