What would you do with this garage floor?

[fastfredracing]

Besides bust it up, and pour new concrete?. This is in the upstairs of my building, it is an old place, and the concrete is in pretty bad shape. I want to do a makeover of this upper area this fall/winter, and the floor is by far the ugliest part of it.
Could it be floated out level? , or is it too far gone, and cracked? I'm not sure if the pictures show it, but it is very uneven in places, cracked, sunken, and then quick patched/ repaired. I have been here 11 years, and it seems stable, I can see no new cracks, and the patchwork seems to be holding good. I keep coming back to race deck garage floor tiles. Any other good suggestions?
I mostly will be storing cars here, but I would like to be able to use a jack, and jackstands on the floor, and do some light duty work

Not seeing any pictures.

I've worked in buildings with floors much worse than you describe.....machine shop
with soaked in oil to boot.

They brought in crews that cleaned, smoothed, and then coated the floor with a thick epoxy resin.......we were skeptical of the effectiveness.

They had just a few spots that didn't adhere and redid them. ....this was a large area. The rest looks great and lasted till I left.....5 years or so.

NOT CHEEP.....but looked great.

Since it is upstairs, I think you should have a structural engineer give you an opinion.

If it doesn't give you too much concern structurally, I'd just grind the worst parts and then refloat it. Finish it off with an epoxy coat. I mean, if you got 10 to 20 years out of it, would you care?

+1 to that.

Won't the existing paint cause problems with bonding any kind of float?

Skim coat and add a pretty errr, manly epoxy finished like was suggested.

I was going to epoxy coat my 22 year old garage floor (small chips, lots of oil stains) but have read far more horror stories than good ones, especially DIY. My epoxy floor kit is still sitting on the dirty oil stained floor. I'm considering going with one of the modular tile floor options so I just go over the old floor instead of messing with it. Food for thought, especially if you are considering hiring a pro to skim coat then epoxy.

Zeke - I think nowadays you could either mechanically or chemically prep it easy enough for a skim coat. Seems easier to me than an R & R.

Clean it up with TSP and pour a skim coat

Ardex. We have used their products with great result. I am not sure about the jack stand, but ask their engineers. easy and not too much prep. It is cheap enough compare to other methods. Many of the other methods fail over time.

Oh, Cjheck out utube on their stuff.

IMHO just throw race deck tiles down and be done with it. Not cheap, but a lot less hassle than pouring a new floor or painting it.
