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It provides adhesion, flexibility and weatherability that far exceeds conventional polyurethane products such as NP1 or outdated polysulfide products.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.

    This is an excellent product used on new concrete steps. I would suggest taping each side of the joint and misting with denatured alcohol for tooling as it is very soft and sticky. If you mess up, let it dry for a day, then easily pull it out by loosening one end. This was my first attempt at caulking concrete and my results look like the picture! If I can do it, anyone can! I also appreciate the quick response from my question left on your website over the weekend and the fast delivery of the product within a few days.

    Excellent sealant for concrete expansion joints. Burned through 120 10oz tubes while completing my project. Consistent quality start to finish. No issues with tool ability. Excellent adhesion with a good match to new and old concrete.

    Concrete Joint selant -- Good stuff!

    It's a bit messy, but what caulk isn't? Seemed to seal well and then accept top sand appropriately. Rain arrived a day later and everything held tight!

    Concrete Expansion Joint Sealant

    Great product. Been using polyurethane sealants that would shrink and fail within 2 seasons. Expect must better performance from 100% silicone RTV. Taped joints and ended up with an excellent job. Very satisfied and great pricing.

    Great product. 1/3 +/- the cost of comparable "off the shelf" products. Just gotta' move fast because you can only tool it for a short period of time before it starts skinning over (having some denatured alcohol to "mist" on it is a big help).

    Concrete Elite expansion joint sealant

    Our contractor recommended this product. I placed an initial order, which arrived very quickly. It's easy to use, forgiving of the novice who's smoothing it out and dries in less than a day. Our application looks professional! One of their reps gave us hints on how to apply it so it would look professionally done. The second order arrived as quickly as the first, which we are grateful for as snow is coming quickly where we live and we needed this project completed before cold weather. Great product, highly recommend.
