Grouts are porous &, as a result, they easily absorb grease, dirt & lime scale. Spillages such as wine, lemonades or greasy substances will cause marks & patches in the joints in the floor. Grouts between wall-tiles, particularly in damp areas like bathrooms, will become dirty & unattractive as a result of mould & lime scale. Equally when such areas are being cleaned, the cleaning water (containing dirt originating from the wall or the floor) will gradually be deposited on the joints between the tiles. The grouts will become dirty & difficult to clean. The solution for this problem is: HG super protector for wall & floor grout.
