Everbuild 507 Rendagrip is an extra grip render bonding agent that contains a fine aggregate to provide an improved key before applying render on external surfaces e.g. concrete, lightweight blockwork, brick etc. The fine aggregates are suspended in a unique waterproof polymer to ensure easy application by roller or brush and an even spread of aggregate avoiding any weak spots in the key coat and preventing the aggregate particles coming loose during application.
507 Rendagrip reduces the porosity/suction of the base substrate and provides a mechanical key from the fine aggregate suspended within the product.
