It's thicker so it stays put pretty good. Use rubbing alcohol on your finger to smooth it. It won't stick to your finger. **Q: My concrete deck is more of a red sandstone color. do you have self leveling for that?** A: I would suggest that you order the limestone color and purchase some brick colored concrete tint powder to mix with it prior to application. **Q: Is this paintable** A: I don't think so **Q: Did you have brown?** A: We do not have the Sikaflex 1A in brown. Thank you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best roof and siding sealant ever *by G***. on November 27, 2025* If you are doing roof work or siding work. This will seal forever. Best stuff I’ve ever found. ### ⭐⭐⭐⭐⭐ Dries very quickly *by D***N on January 9, 2026* Excellent product . ### ⭐⭐⭐⭐⭐ Best stuff ever! *by G***A on July 3, 2025* I’m giving a five star because the batch I received has a 8 month shelf life and the previous two batches also had a long shelf life, which seems to be rare when it comes to Sikaflex. Sikaflex 1a is the best stuff you can get. It works on everything.. Don’t use it on something you plan on taking apart later lol it’s permanent stuff. If you’ve never tried it, you must get some because every contractor and handyman should have this product in their arsenal. It works great on concrete, wood, roofs, and almost everything else. ## Frequently Bought Together - Sikaflex 1a Kit - One Component, Flexible, Non Sag, Polyurethane Concrete and Masonry Sealant for Vertical and Horizontal Surfaces, Sikaflex 1a 10 oz (Limestone, Pack of 12) - 3/4" Diameter x 100' Length Backer Rod Caulk Saver Foam Backer Rod for Gaps and Joints Backing Concrete Filler - Mutual Industries Standard Backer Rod, 1100 Linear Feet, 3/4" --- ## 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.pl/products/487956414-sikaflex-1a-kit-one-component-flexible-non-sag-polyurethane-concrete](https://www.desertcart.pl/products/487956414-sikaflex-1a-kit-one-component-flexible-non-sag-polyurethane-concrete) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
