Drylok 1 gal. Natural Look Masonry Sealer

Drylok 1 gal. Natural Look Masonry Sealer is a non-yellowing protective coating designed for use as a penetrating sealer or concrete curing membrane. It penetrates deep into masonry surfaces to provide strong protection against acids, alkalis, road salts, de-icing compounds, household cleaners, gasoline, oil, and weathering while preventing dusting, staining, and spalling. When applied to freshly poured concrete after the surface has set for 24 hours and excess water has been removed, this sealer acts as a concrete hardener by controlling water evaporation to maximize concrete hardness. Suitable for both interior and exterior vertical and horizontal surfaces, it creates a moisture vapor barrier with easy warm water and soap cleanup.
