Advice on repairing floor

[1320it]

This is the current condition of the garage floor in my house. I'd prefer to put epoxy on the ground than tiles.

What would be involved in repairing this?

Grind it well. See what it looks like post-grind. You are probably looking at some pre-patching and then go for a full-flake system.

Agree with LegacyIndustrial. Grinding it first will get the loose stuff out and then use some kind of patch. I use a cement based floor patch and then coat the floor. The problem with pitting like that is it can disintegrate if you don’t grind it out. You can’t just coat it or patch it.

What size is your garage? Depending on how big the garage is, you may be doing an awful lot of grinding. I am assuming you will want the floor to be level when you are done, so you will need to grind the entire floor down to the same level as you grind the pitted areas.

Grind, fill pits, grind filled area level.
You dont have to grind that low, could be grinding forever!!

You can grind the pits and then fill it in with a patch and the patch area will stick to the floor without flaking off? I am sure you know infinitely more about this than I do, I was not aware you could do that. I had thought the patch area would be really thin and consequently would have a tendency to flake off, obviously I would be wrong. I learned something new today.

Your going to grind the whole thing 1x. Make a slurry patch, trowel over the pitted areas. Once cured, grind the patch flush. The slurry patch is epoxy/sand. Not cement

Sorry to hijack but I have a warped floor with some low "ponds" and some high "humps" in my 2-car garage. I plan to grind down the high spots but would like to fill the low spots to bring it up as much as an inch to get the entire floor flat and level. Let's say I'm going to need a 1-2 cubic yards of epoxy patch/fill. Is there a better product than a bucket of patch? I plan to epoxy coat afterwards with flake and DIY.

These pictures actually look allot like the floor in my basement I want to fix. If you more forward with any of this please update on your success.

I like the idea of grinding, then patching, then grinding again but the rental is $170 a day from the local home depot so I can't imagine renting twice. Maybe a once over the entire floor with the pro rental grinder, patch, and then grind the patched areas with a handheld angle grinder?
