The original impregnating sealer designed for the protection of all medium to dense porous surfaces. 511 Impregnator forms an invisible barrier that is resistant to moisture and stains while allowing vapour to escape. 511 Impregnator is not a surface coating and will not alter the natural look. All surfaces treated are harder and less slippery. Independent laboratory tests show 511 Impregnator outperforms competitive products.
