A penetrating sealer for use on external concrete surfaces where a natural finish is desired. This sealer forms a cross-linked matrix below the concrete surface, minimising the ingression of surface water into the concrete, and it will reduce stain risk to a degree also.
As the sealer does not coat the surface, staining and marking of the concrete surface is possible. However, most common contaminants can be removed by treating with PFL Concrete Cleaner, or for tannin stains, the PFL stain remover.
It does not increase slip risk as it does not alter the slip resistance coefficient of the concrete.
