Weather Worker™ 100% J29A is a proprietary 100% silane that penetrates into concrete or masonry and provides long term weatherproofing protection. Weather Worker 100% J29A 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 100% J29A will not darken the surface or leave a visible surface film. It is ideal for aesthetic / architectural surfaces.
