MAPEI Flexcolor CQ is a ready-to-use grout that dries harder than cement-based grout. The residue that is left behind, when not properly removed during the grouting process, can appear as a clear film that can become tacky. This residue can easily be removed using MAPEI’s UltraCare Heavy-Duty Stone, Tile & Grout Cleaner.
