AbatronAbocrete Kit - Self-Leveling Concrete Epoxy Patching and Filling Compound - Concrete Repair and Cement Crack Filler 1.25 Gallon Kit - Without Sand - Light Gray

I have a 48ft x 6ft concrete porch that I discovered had a bad long crack after I removed old carpeting from it. I had no prior experience with fixing concrete before this. I followed YouTube videos and bought a grinder, a concrete cutting wheel called crack chaser (I highly recommend), foam backer-rod, sand and chose Abocrete as the repair filler.I widened the crack to 0.5" and about 1.5" to 2" deep with the grinder and then tucked the foam rod into the crack as deep as possible with popsicle sticks so that the Abocrete epoxy would fill the crack and not leak underneath.Then came time for the Abocrete. I have some tips and lessons learned that hopefully will help others when using Abocrete. The instructions say to mix some of the resin and hardener without sand first and then paint the inside of the crack before mixing in sand and attempting to fill the crack completely.So I mixed the can of resin and hardener in a bucket, and then I painted the inside of the crack. I immediately went to mix in the sand, and to my dismay, the Abocrete was rock hard. After reading lot of factors caused the Abocrete to harden. One factor is the temperature was very hot over 90° F outside which shortened the working time. I also mixed the full amount of resin and hardener in the bucket. Apparently to more you mix together faster it hardens. So you want to mix a small amount at a time.My first batch was wasted since it hardened before I could fill the crack. But the little bit that I did get to paint the inside of the crack with was rock hard and very promising. So I ordered a 2nd batch and filled in the crack a few days later. This time I used a smaller amount and not the entire contents. I also added sand to the mix until it was thick enough to fill the crack like hot peanut butter but still thin enough to seep into every crevice. I could not be happier. The expoy is super hard and self-leveled nearly perfectly. I'm going to sand down an excess, but other than that I feel confident that this is a solid repair. I was worried about the condition of my porch when I saw the crack, but now I can sleep again without worrying about the crack in my porch. Worth every penny, just make sure you read the instructions thoroughly and don't make the mistakes I made which caused it to harden to fast. My second attempt went perfectly.

Very hard to work with. Does not level as easily as expected.Does seem to be extremely hard.Big concern tiny air bubbles came up as it set up, requiring some sanding to take down ridges.Not sure what happened followed instructions to the letter

You must mix the 2. Exactly proportional. liked it but thought it was a little expensive for what you get.

Had some areas where the concrete was eroded by salt in the garage. Mixed with sand and it was more difficult to work with. I ended up grinding the surface to blend it in. The color is slightly off. The big thing is it filled the erosion and looks like it will be there forever. Not the most easy stuff to work with without experience but I’m still happy with the outcome.
