Project 1™ 9000 SERIES 100% RTV Concrete Expansion Joint Sealant is a high quality, single-component, neutral cure, 100% silicone sealant designed to provide superior performance when used in concrete expansion joint applications. It provides adhesion, flexibility and weatherability that far exceeds conventional polyurethane products such as NP1 or outdated polysulfide products. It will withstand UV exposure and continue to perform years after other sealants have failed. It will not yellow or discolor even after years of outdoor exposure. This product is custom formulated for us by the nation’s leader in silicone sealants so you can count on consistent quality. Our pricing is similar to inferior products on the market so the decision is easy to make the upgrade to this superior, long lasting sealant.
