Weather Worker™ 40% J29 is a proprietary 40% silane that penetrates into concrete or masonry and provides long term weatherproofing protection. Weather Worker™ 40% J29 is a single component product that is ready to use and typically requires only one application.
The silane molecule can penetrate deeper into the substrate than conventional sealers and even deeper than a typical siloxane sealer. Once the silane molecule penetrates the surface it chemically reacts with, and bonds to, the concrete or masonry substrate. As a result of the strong chemical bond, silane waterproof protection will last many times longer than conventional coatings.
Weather Worker 40% J29 will not darken the surface or leave a visible surface film. It is ideal for aesthetic/architectural surfaces.
