Old Master's penetrating sealer

Old Masters® Penetrating Sealer is a clear, penetrating oil formulated with natural Tung oil to protect and seal a variety of surfaces including wood, masonry and concrete. This product seals surfaces to resist weather, mold and mildew. Suitable for both interior and exterior applications, this product can be used as a seal coat under clear finishes or paint. On wood surfaces, this product seals out moisture to enhance the life and natural appearance of wood while preventing staining and checking. On masonry and concrete it will produce a moisture seal that reduces concrete dusting, staining and efflorescence of masonry and brick surfaces. Sealer also hardens masonry and natural rock surfaces and reduces frost damage
