Stop Mould Flexible Wall Grout


Stop Mould is a fine, smooth finish grouting material for internal and external tiling joints up to 5 mm wide. Stop Mould contains Rock-Tite polymeric binders, making it ideal for use with all types of tile including glass where it has excellent adhesion characteristics. The product needs only the addition of water, high flexural strength makes it ideal for dry lined walls and surfaces subject to vibration and durability, such as power showers. Stop Mould grout contains Norcros Stop Mould Anti Bacterial Fortification to protect against the build up of mould and the discolouration of grouting. The grout is water resistant but not impervious to the passage of water. In areas of potential water ingress, preparation of the surface with Norcross Wet Seal should be considered. Where an impervious joint is required Norcros Super Epoxy Grout should be used.
