UltraTileFix ProSuper Grip has been specially formulated for its non- slip, high grab properties, which allow the speedy application of standard and large format wall tiles. The product is suitable for intermittently wet conditions i.e. domestic showers, kitchens and bathrooms. It contains an antifungal additive, which prevents the build up of mould. NB: Porous natural stone tiles need to be checked for compatibility to avoid staining.
