Review: Much better than I expected. - This sounded too good to be true, but it's actually easy to use, and does a nice job filling little cracks and holes. I'm a renter, and have found that if I complain about little problems I might get an increase in my monthly bill. But, I was afraid bugs would make winter homes in the cracks around my door way. This isn't an elegant fix by any means (probably could be if someone wanted to take a lot more time), but it fills in openings in just a second or two, and I found it very easy to use. Review: Great Product! - this patch works really well, applying it in small layers works best, I had 2 cracks on a vertical surface and it stayed in place, it didn't develop cracks when drying, and you can push it into the crack easily ## Features - REPAIRS CRACKS AND BREAKS IN CONCRETE: Premixed formula makes repairs easy - DRIES A LIGHT TO MEDIUM GRAY COLOR: Ideal for lighter shades of concrete - WON'T SHRINK OR CRACK: Provides maximum flexibility for a permanent repair - INTERIOR OR EXTERIOR USE: Can be used inside or outside - WATER CLEAN UP: Cleans up easily with soap and water.

I'm a renter, and have found that if I complain about little problems I might get an increase in my monthly bill. But, I was afraid bugs would make winter homes in the cracks around my door way. This isn't an elegant fix by any means (probably could be if someone wanted to take a lot more time), but it fills in openings in just a second or two, and I found it very easy to use. ### ⭐⭐⭐⭐⭐ Great Product! *by A***N on July 12, 2026* this patch works really well, applying it in small layers works best, I had 2 cracks on a vertical surface and it stayed in place, it didn't develop cracks when drying, and you can push it into the crack easily ### ⭐⭐⭐⭐ So far, so good *by S***E on September 2, 2022* Used this to patch a moderately large chip in a sidewalk. Wish they sold a smaller pint size since I didn't need this much. This is the smallest size you can get as far as I know, which is 1 quart or 4 cups. It comes in a plastic tub container with instructions to use a screwdriver to help you open and a hammer to close it. You can open and close it by hand, but I get why it might sometimes arrive open by mail since the plastic lid is easy to deform if something lifts it up. My plastic tub arrived fine and the material was not open or dried out. I got the package with the plastic knife set. You could probably buy this cheaper in a big-box store, so you're paying extra for the convenience of delivery. It's a lot lighter in texture than I was expecting. Other reviews call it "fluffy," which I would agree is the best description of it. I thought it would be denser, but it has the texture of cake mousse. I do wish it was a little denser so it would be easier to scoop and pack into deeper cracks. It does have a tendency to stick a little to gloves and spreading implements. I used the plastic knife set, but maybe it's easier to spread with a metal knife. I was worried it wouldn't set due to the texture, but it seemed pretty hard and dry 24 hours after the patch. I did apply it on a summer day where temps were between 70s and 80s. Didn't shrink, but it seemed to sink down a bit and "level" into the crack after 24 hours. I could probably do another layer, but I'm waiting to see how it holds up to rain and whether it will "melt off" like some negative reviews mentioned. So far, so good though. ## Frequently Bought Together - Red Devil 0644 Concrete Repair Patch, Cement Crack Fillter, Pre-Mixed, 1 Quart, Pack of 1, Gray, Made in USA - 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 7079860500 Concrete Crack Filler, 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.sk/products/44551961-red-devil-0644-concrete-repair-patch-cement-crack-fillter-pre](https://www.desertcart.sk/products/44551961-red-devil-0644-concrete-repair-patch-cement-crack-fillter-pre) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-01*
