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 that have been laid onto a solid permeable base using Rock-Tite Mortar. 

Rock-Tite Brush In Grout has been specifically developed to match 4 into 1 and Flexible Wide Joint Grout colours to complement interior tiles and allow the creation of a continuous aesthetic from indoor areas to exteriors. When used on a free-draining permeable sub-base, Rock-Tite Brush In Grout can be applied in most weather conditions down to a temperature of 3°C. 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.
