Norcros Rock-Tite Brush-In Grout is a cement-free brush in permeable jointing compound designed for filling joints from 3mm wide between concrete, natural stone
and porcelain paving slabs which have been laid onto a solid permeable base using Norcros Rock-Tite Mortar.
Easy to use and offering the ultimate in convenience, Norcros Rock-Tite Brush-In Grout has been specifically developed to match Norcros 4 into 1 and Flexible Wide Joint Grout colours to complement interior tiles and allow the creation a continuous aesthetic from indoor areas to exteriors. When used on a free-draining permeable sub-base, Norcros Rock-Tite Brush-In Grout can be applied in most weather conditions down to a temperature of 3C. Do not apply in heavy or prolonged rain as this will extend the curing process and may result in an uneven surface texture once the grout has cured. Any left-over grout can be poured back into the tub and stored by covering with water to at least 50mm above its surface. Watch Rock-Tite Installation Video
