CrackWeld DIY Concrete Floor Repair Kit (4-Pack) - Repair Concrete Cracks in Basements, Driveways, Garages, Patios, & Pool Decks

When I removed my carpet I discovered a long crack in my concrete floor. The crack was so wide and had so many runners the floor "rocked" in a few places. I originally wanted to use ceramic tile on the floor. But you can't put ceramic tile on an unsteady foundation. I watched the video several times to make sure I was going to get it right. You have to work really fast because this stuff sets up fast. Make sure you're organized before you start applying this product. I used 4 cartridges to repair my floor. This product really worked well. The crack was repaired and no more "rocking" floor. The guy who installed my flooring was really impressed with the repair.

Works great for fixing basement floor cracks. Sets up pretty fast, so it's a two person job. Also, when it dries, it's hard as concrete and needs to be ground smooth; sandpaper is almost useless.

The product worked fine when you could get it of the tube. Mixed with the sand and made a nice seal of the crack on the floors that I was sealing. The mixing nozzles clog up quickly. I ran out of nozzles before I used two tubes out of 4 that I purchased. Most disconcerting was the fact that I called the company to purchase more mixing nozzles, the never called me back after I left a detail message stating that I wanted to purchase more nozzles. Pretty bad customer service if you ask me.

Old house, so many cracks in basement floor. This things work great. It fills almost hair line cracks also.

Used this product to repair some cracks and small holes in a Florida driveway. Initial impression is it does everything the manufacturer says it should. I did need significantly more sand than was included. Buy all purpose sand and screen it through a Dollar Store stainless strainer to solve this concern. It does set up hard in 15 minutes at 75 degrees F. I found that the best way to smooth it after hardening was to use an angle grinder with a diamond cup wheel. Highly recommend you have a helper - would have been really difficult to do alone. Follow the directions and it will hopefully work well for you. Cannot comment on longevity as the work was just completed. I am a 70+ year old DIYer - easy work even for me!

It needs more sand and a few extra mixing tubes. Otherwise it's a great product.

Application was very quck and simple to do. Great product to seal concrete radon issues.

Follow all instructions the next day most of the cracks where full of bubbles, the last tube only delivered two feet before it went dry this was money wasted
