Clear Waterproofing Sealer is a transparent sealer that penetrates the surface of dry, porous materials to help prevent moisture penetration and water damage. This can be used on wood, concrete, brick, masonry, canvas, stucco and other substrates. It dries clear and allows the surface to age naturally. This product will protect against salt water. For new construction, prevent weathering and water damage by applying Clear Waterproofing Sealer immediately after installation.
