Rust-Oleum 301012 Concrete Patch & Repair, 24 oz, Gray

Very expensive for the small amount of product but works excellent. Not intended for large projects unless you can afford it. Gasoline will dissolve it even after its cured if it's spread too thin over a patch.

This product was great. It was rather easy to mix, fill, and level out. I used it before doing my rock solid garage concrete flooring, and it did a great job filling cracks. I would recommend picking up some quikrete concrete repair and filling large holes or cracks first, once they cure, grind them smooth, and then go over the top of them with this. This rustoleum crack filler was great for sealing in the quickrete, and filling in cracks. It sanded down nicely and easily to get rid of the raised edge from application. I used a soft applicator, an old auto body filler type one to mix, and apply. That worked well for scraping most access off and also being flexible around areas that weren’t exactly level. After sanding this product down, and applying the rock solid polycuramine floor coat, I couldn’t see this product through it. In reviews, and videos that you can, I think they either didn’t sand it or maybe didn’t apply the floor coat thick enough. I used the light gray floor coat kit, this stuff applies gray, so could also be part of why you can’t see it. Overall I am very satisfied. I have plenty left over also so I can help friends with their garages now that they have seen how mine turned out. I recommend only mixing a little at a time. If you run out you can just simply mix more. I used 1 popsicle sticks per container to grab it out and the soft applicator to mix and finally apply it. I wouldn’t recommend using a hard putty knife and grabbing some out of one can, and dipping into the next with a dirty knife and mixing it like that. I saw that on several videos. When you go back to use it in the future I’d imagine there will be rocks or something of activated material mixed in. The packaging says this can also be used to help anchor in screws into masonry, so I will be saving this as a future tool/ trick to help get a job done. Take care of your product and Itl be there to serve again!

I used 3 kits on my two car garage. My garage floor had several cracks and dips. The patch kit worked really well. It made the epoxy look nice and smooth.

This is the only product that stays put on my basement floor. It is a bit hard to work with, but can be sanded if you need to smooth it out once dried. My basement floor continually had issues with any product I used as a filler. So far this product is working the best of anything I tried. It takes a bit longer to dry than expected, but it is worth the wait.

I have used this product in a couple ways and I love it. If you have a cement statue of something it is wonderful to patch up chips and flaws as I have used it many times for this. Now I have a wall in my basement that is giving me a problem with moisture so I'm using this product to cover these blocks as this is harder than cement when it drys and it is paintable

I decided to clean, patch and stain my boring front porch when I re- made my porch this summer. It had a lot of cracks. I took all the concrete patch products in Lowes, chose a nice patio furniture display to sit and I read them all. I chose the Rustoleum. It's easy to work with and it dries rock hard. I mixed it in small batches because it dries in about 20 minutes. Once it's dry it's harder than the concrete. I sanded the seams down flat using a grinder with a sanding disc. I am really happy with how it turned out. I ended up painting the seams, they are now part of the final result. I wanted a turquoise stone look. So I used the patched seams in the design. I was then asked to repair the cracks in a neighbors very large, very cracked front porch floor. That also came out great, and those were bad cracks. I've used 3 boxes of this concrete patch, it's well worth the cost.

Wow what a very Amazing product. First let me say that I am Not a professional contractor. I am just your everyday handyman and so over the decades I have used a few products that would promise you the world but this is one of the few times that the products has exceeded the marketing department. Hats off to,those brilliant engineers that are responsible for creating this product. In fact I personally think that Rust-Oleum should at least triple the pay of all of those very intelligent men and women that worked on developing this. I used it for some crack repairs but a lot of it and I used 5. - 24 oz batches of it to put a skim coat on some existing painted concrete the was in doors. The deepest repair I had was no more than 1/4 inch deep and within 4 to 6 hours it was very hard and and after 24 hours it was hard as a rock. I decided to sand it a little bit so the floor paint that I put over it had a little something to hold on to and now it is still looking great. Thanks so much again for such a great product
