I've been working long and hard to turn my garage into a pleasant place to hang out and to work on projects. Its now neat and organized. The one thing I have not yet addressed is the floor. The concrete was probably poured in the early 70's and it had a rough life.
The pictures show what I am working with
The problems:
1) It has a major crack down the middle from the door opening to the back wall which is about 1/2 inch wide and vertically misaligned by about 3/8 inch at the door end and closes down to a level hairline at the rear wall. I've watched it over the last several years and it does not seem to be growing or moving at all..
2) It has a couple spots along this crack which have spalled out or have a loose piece down in the crack.
3) It has several smaller cracks which branch of of the major center crack. They are less than a 1/4 inch wide and level across them.
4) There are several areas where the concrete is permanenetly stained with oil that has soaked down into the concrete. The floor had been pressure washed and repeatedly cleaned with a concrete cleaner just prior to taking the pictures. From the appearance and the residue I scraped up off the surface of the floor I'd say used motor oil spiled in these areas years ago and was left without ever being cleaned up. Water doesn't bead on these spots and will soak in somewhat, but it takes longer than in the unstained parts. I don't think it can be made any cleaner.
My plan/expectations
I am not shooting for perfection on this. i'm just tired of looking at the stains and digging dirt and the occasional dropped screw out of the crack.
I do not intend to slab jack or grind the floor to level it at the crack in the door opening. Figure I'll simply try to "ramp" the repair in the big crack from one height to the other.
Right now I am leaning toward the epoxy-coat product in their standard grey color with a heavy application of their three color grey chip mix.
I have already purchased backer rod to place inthe big crack and a couple different concrete crack repair products which I've yet to apply, as I am not sure of their compatabilty with the epoxy products.
Looking at the pics and from the description, do you guys that have done this on less than pristine floors think this is do-able and likely to result in decent outcome?
