Review: Professional-Quality Self-Leveling Sealant That Makes Concrete Repairs Easy - Professional-Quality Self-Leveling Sealant That Makes Concrete Repairs Easy I've used several products for sealing concrete joints over the years, and Sikaflex continues to be one of the brands I trust. This self-leveling polyurethane sealant flows nicely into horizontal expansion joints, creating a smooth, professional-looking finish without having to spend time tooling the surface by hand. The sealant adheres well to properly prepared concrete and cures into a flexible, waterproof joint that should hold up well to changing weather conditions. I also like that it can be painted after it has fully cured, making it easier to blend repairs into the surrounding concrete if desired. Application is straightforward with a standard caulking gun, and the narrow nozzle allows for good control. Just be sure to thoroughly clean the joint before applying the sealant, as good surface preparation makes a big difference in the final result. One thing to keep in mind is that this is a self-leveling product, so it's intended for horizontal joints only. It's not suitable for vertical surfaces because it will flow before curing. Wearing disposable gloves is also a good idea since polyurethane sealants can be messy to clean off your hands. Bottom Line: This is a high-quality, professional-grade concrete joint sealant that's easy to apply, self-levels beautifully, and cures into a durable, flexible, waterproof seal. It's an excellent choice for driveways, sidewalks, garage floors, and other concrete joints, making it an easy 5-star recommendation. Review: Good stuff, very durable and better than the BB store prices - I have been using this product for many years. I think it is the best self leveling product on the market. I bought it this time for a long1/4in crack in my garage floor. I first blew out the crack, then inserted a pencil size, foam filler and pushed it down into the crack about 1/4-3/8in to seal the bottom of the crack. If you don't seal off the bottom of the crack or void....you will use/waste a lot of product. Fill the crack slowly keeping the material slightly proud and then be patient. It takes a couple of days to completely cure (depending on the thickness of the application). Good stuff, very durable and better than the BB store prices. ## Features - EASY VERSATILE APPLICATION — Apply self-leveling concrete sealant to expansion joints without concern for uneven surfacing.

I have long expansion joints running parallel to the slope, but it's not super steep.** A: I like the other answers, and read them before I did my project. My driveway has about a 5-10% grade, with perpendicular and parallel joints, 1" width. I used 1.25" backer rod from an Amazon seller, but I bought the Sika sealant locally so I could return the excess. My fill was 0.25" The perpendicular joints were no problem. I made a couple of passes once it was clear that they wouldn't flow over. The flow along the parallel joint was so slow that it never sagged significantly. I had to add a small amount at the top a couple of hours later. I used a heat gun in the beginning, thinking that it would speed the set. Wrong. Low heat actually softens the sealant. But the heat gun was helpful in bringing bubbles to the surface and making them pop. Rough or irregular spots responded well to the lowest heat (Wagner Furno 500). **Q: It says this product is paintable but it does not say that anywhere on the tube. Has anyone painted it with long term success?** A: I have never seen this product painted. It is a self-leveling caulk for wide joints in concrete primarily. Used around pools and in expansion joints. I always allow it to start to set then cover the surface with fine washed sand (no dust). This gives it a better appearance and extends the life years beyond what it would be without some UV protection. It should be used in a fairly thin application either with foam joint material or sand below it. Typically it is only 1/4 to 1/2" thick. **Q: In roadway, how long before heavy traffic can cross without damage to the caulking?** A: I put this on my concrete drive and now for 2 years I have not had any problem. Great stuff **Q: Will this stick to plastics such as vinyl?** A: It should ## Frequently Bought Together - Sikaflex Self Leveling Sealant, Gray, polyurethane with an accelerated curing capacity for sealing horizontal expansion joints in concrete, 10.1 fl. oz Cartridge - M-D Building Products - Versatile Gray Foam Backer Rod Set 1/2in x 20ft - Essential Caulk Saver for Sealing Concrete Gaps, Expansion Joints, and Crack Filling (71480) - M-D Building Products - Versatile Gray Foam Backer Rod - Essential Caulk Saver for Sealing Concrete Gaps, Expansion Joints, and Crack Filling, 3/8 by 20 Feet, (Pack of 2) (71464) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/2023067-sikaflex-self-leveling-concrete-expansion-joint-sealant-gray-10-1](https://www.desertcart.sn/products/2023067-sikaflex-self-leveling-concrete-expansion-joint-sealant-gray-10-1) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-23*
