Can you re-grout with LATICRETE SpectraLOCK PRO Grout?
Yes! For existing grout joints which have deteriorated or discolored, LATICRETE SpectraLOCK PRO Grout is excellent for regrouting. The old joint must be routed out 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 procedure.
