Grout Renu is a specially formulated chemical to clean old and dirty grout. Grout Renu is a blend of detergents, acids and thickeners that allow the product to cling to walls and floors and thereby giving the chemical time to purge dirt form the grout.
The original colour of the grout will be restored. It is recommended that the grout be sealed with Grout Seal once it is clean.
For a 3mm grout gap, coverage is approximately 700 linear metres. For a 6mm grout gap, coverage is approximately 500 linear metres.
