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.

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.

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.

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.

Did not cover much area

Item works as described and it very durable.

Followed direction precisely and this product did not create a seal from water and moisture seepage through the crack repair. Any water present inhibits it abilities.
