I think the push for epoxy floors in every garage is overkill

Last week I spent three days grinding my concrete slab in my Charlotte garage, just to put down a $700 epoxy kit. It looked great for about 48 hours. Then I dropped a wrench from my workbench and it chipped right down to the gray concrete. Everyone online acts like it's the only way to go, but my experience says it's not tough enough for real shop work. Has anyone else had epoxy fail on them and gone back to just sealed concrete?

Read that epoxy needs a thick top coat, unlike quinn958's chip.

Yeah I totally feel that, I had a similar issue with a chip in my garage floor epoxy from dropping a heavy toolbox. What ended up working for me was using a two-part epoxy repair kit from the hardware store, the kind that comes in a syringe. I cleaned the area really good with acetone first, then I built it up in thin layers letting each one dry for like an hour before adding more. Took a few coats but once I sanded it flat with 400 grit and polished it you could barely see the spot. Just be patient with the drying time because if you rush it the repair turns cloudy and stands out worse than the chip did.

That "looked great for 48 hours" line hits hard. I had the same thing happen with a dropped socket set, just a little chip that shows all the gray underneath and drives me nuts. I ended up just putting down those interlocking garage tiles over the epoxy mess.
