Grout Seal is a specially formulated sealer for sealing and protecting grout that is porous. In cases where glazed tiles have been applied to the floor, very often the grout has not been made waterproof and therefore the grout is porous and will get dirty from regular cleaning.
Grout Seal is designed to seal to seal floor grout mainly but may be used on wall grout. Sealing grout helps to make the area more hygienic as this prevents bacteria and mildew from growing in the grout lines.
For a 3mm grout gap, coverage is approximately 700 linear metres. For a 6mm grout gap, coverage is approximately 500 linear metres.
