3M Scotch-Weld Concrete Repair DP600, Gray, Self-Leveling, contains 2 Mix Nozzles, 8.4 fl oz Cartridge

Was easy to apply and worked as promised. I have patched a hole in my sidewalk multiple time just to have it break out after a few week. This product is holding strong. Not very much in the tube had to get a second to fill a hole 2in deep at the deepest and 4in across.

I have used this product before, and was okay with it. It is NOT self leveling to the extent that would be acceptable, and it is very difficult to work after it is applied. It sets up FAST. On the other hand, 3M Concrete Repair is very strong, and holds well. I will probably use something else next time.

We use all the time to patch concrete cracks. Lasts pretty much for ever. Great product. We have used for 10 plus years. Use to come in smaller applicator but these are good. Just need to do more and plan out. It does dry fast. And I do mean fast.

Easy to use!

So I had a job that needed to be filled this product seemed to fit the bill but when they set it sets in 5 min it sets fast too fast. If you don’t have forearms of steel you will run out of juice before you get it all out and the tube is deceiving it will only pump half way I cut the tube open and there is only a 3rd in the tube to start.

Take an 8 oz cup, look at it, if you think that's all you need, good to go. Stuff sets up super fast, super hard. My only issue was I didn't have enough to fill the void. Oh well, it's water tight. Crazy price. I think I'll try regular epoxy you mix, as the convenience and beauty of this stuff is hard to swallow when you look at the cost.

Dries in minutes to super-hard seal. Awesome!!

Item works as described and it very durable.
