Dayton Superior – Weather Worker™ 40% J29

Weather Worker 40% is a one-part silane molecule that 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. Ideal for; Cast-In-Place Concrete, Precast Concrete, Exposed Aggregate, Mortar, and Stucco.

• Small silane molecules result in deep penetration
• Outstanding protection against deicing salts and chloride ions (over a 90% reduction)
• Passes the N.C.H.R.P Report 244
• Will not change the traction or skid resistance of a surface
• No color change/will not darken surface
• Strong chemical bond to the substrate
• Can be applied down to 32°F (0°C)
• Dries quickly, can be reopened to traffic within 1 hour
• Improves adhesion for solvent based paints
