Over-washing is a result of an improper grout installation. Over-washing includes using too much water and excessive wiping of the grout lines, at the time of installation. Over-washing dilutes the liquid urethane and degrades the grout composition. This results in improper curing and produces a very course, rough finish on the grout surface; discoloration within the grout line; "peaking" of grout in the grout joints; and/or grout pulled out of the joints. Eventually, the top layer of the degraded grout will fleck, crumble, and crack.
Over-washed grout lines may be repaired by following the grout removal and repair process. The instructions are available on our website at: Grout Replacement
