Its premixed, acrylic latex formula offers easy application, fast curing, and eco-friendly low VOC compliance, making it the go-to solution for professional-grade concrete repairs on a variety of surfaces. ## Description No garage or tool shed is quite complete without a supply of this Sikacryl ready-mix concrete and cement patch. It's the premiere solution for unsightly cracks and spalls in foundations, patios, balconies, steps, masonry, driveways, sidewalks and more. You only need a putty knife or trowel to apply it and some water to clean up afterwards. In a few hours your patch will set, and in a day or so, it will cure (the exact timing depends on factors like atmospheric temperature and humidity). It works on both vertical and horizontal surfaces. For cracks and spalls deeper than 1/4-in., two or more applications should be made. Review: Crack Fixing Made Easy—A Ready‑Mix Patch That Works While You Relax! - The Sika Sikacryl Ready‑Mix Concrete Patch is one of those rare repair products that actually makes home maintenance feel straightforward. Because it’s premixed, there’s no messy blending, no guessing at ratios, and no rushing before it sets. You literally open the container and start applying it directly to cracks, spalls, and small holes, which makes quick fixes around the driveway, patio, or garage feel almost effortless. The texture spreads smoothly and fills gaps cleanly, giving you a neat finish without needing professional tools or experience. Once applied, it begins curing right away, and while it firms up on the surface fairly quickly, it takes about 24–48 hours to fully harden, ensuring a solid, durable repair that holds up over time. If you want a concrete patch that’s simple, reliable, and refreshingly user‑friendly, this one delivers exactly what a DIYer hopes for. Review: Works great and is very affordable! - ★★★★★ Easy to use and works great! This concrete patch was easy to use and came ready to go right out of the container.

It is too thin to support itself in a quantity large enough to fill a basketball size hole. **Q: Is this waterproof and can be used to repair fountains? Im afraid water will soften it.** A: I’m sure it’s waterproof. I have it holding up my driveway wall **Q: Does this dry hard like concrete? I need to patch a 1 1/2 inch hole in a concrete block wall around an exterior faucet.** A: Yes, it does. I used it to patch up my exterior brick when I had to replace my outside water spigot. **Q: Would this be good for repairing cracked or broken fiber cement roofing shingles--would it serve as adhesive to hold the shingles to roofing felt?** A: I would not use this to repair fiber cement roofing shingles. I do not know if or how well it would stick to roofing felt. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Crack Fixing Made Easy—A Ready‑Mix Patch That Works While You Relax! *by K***H on September 5, 2026* The Sika Sikacryl Ready‑Mix Concrete Patch is one of those rare repair products that actually makes home maintenance feel straightforward.

This concrete patch was easy to use and came ready to go right out of the container. It spread smoothly and worked well for filling and repairing cracks and small damaged areas.

Great product for small concrete repairs around the house! ### ⭐⭐⭐⭐ Birdbath *by B***M on July 23, 2026* UPDATE: Might not have been the best idea for inside of the bird bath. Noticed the birds don’t frequent it as much. Will try to pressure wash off the inside or coat with something else. Purchased this concrete patch to repair a couple of small cracks in my concrete birdbath. Prepped the birdbath, cleaned, bleached and scrubbed. Took the air compressor and blew at the cracks to make sure nothing was left. Very easy to apply and appears to have done the trick. I let it cure for 48 hours to be on the safe side. I had planned to sand down a few rough edges, but hey it doesn’t have to be perfect for the birds and squirrels, so I skipped that. As other reviewers have mentioned the container leaks. First one I ordered had leaked out of the seal. On the replacement order they sent, same thing, but not as bad. So I made a judgement call and decided to use it. Product would probably benefit from having an inter foil seal on the container. ## Frequently Bought Together - Sika - Sikacryl - Gray - Ready-Mix Concrete Patch - for Repairing spalls and Cracks in Concrete and Masonry - Textured - 1 qt - Putty Knife, 4Pcs Spackle Knife Set (2, 3, 4, 5 in), Stainless Steel Paint Scraper, Taping Knife Tool for Repairing Drywall, Removing Wallpaper, Applying Putty, Plaster, Cement, Adhesive - DAP 37584 Liquid Cement Crack Filler, 1 quart, Gray --- ## 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.hr/products/68611715-sika-closed-cell-foam-backer-rod-gray-3-4-diameter](https://www.desertcart.hr/products/68611715-sika-closed-cell-foam-backer-rod-gray-3-4-diameter) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-20*
