Damaged garage floor

We have available a concrete based patching material called Top and Bond.
It works well and can fill thin voids.
You may be able to find a similar product where you are.

zemonti, I didn't say patch it with concrete. I said saw cut first. If I were going to try to patch it, I would use a mortar mix with a bonding agent or the product that Greg mentioned.

Just a thought, but it looks to me like the original surface was worked a bit too much. As you trowel and trowel the surface you push the larger stones (the aggregate) further down and bring the cement, water, and finer materials to the surface. This is how they get a smooth surface out of a concrete mix that is full of stones. But, if they work it too much, the surface is all fines and water not as durable.
I'm sure the concrete pros can clean up (or throw out) what I'm trying to say.

As Bud said, the pix show what appears to be surface failure caused by overworking and/or too high a water-cement ratio. A simple patch job will do nothing to improve things, as there's just too much unsound and debonded concrete to (economically) repair. All of the questionable material should be removed and completely replaced, full-depth, with a new slab. A less extensive (and less expensive) alternative would be a thin-bonded concrete overlay, performed by someone familiar with the process.

Side note of no use other than to point out that this is a commercial parking garage from the picture, not a residential pour. So in many ways it probably is an over pour on top of a reinforced substructure.

zemonti, your main concern is to use something that will bond. Forget about shiny. Going back to my original response, I would saw cut a square section about 2 to 3 inches deep & fill it with a concrete mix.
Is that the parking garage to an apartment building?

I agree with Greg, Top and Bond is the most inexpensive albeit temporary solution. I have a similar problem in my garage and I do a T & P about once every two years. It holds up to salt and water and freezing temps along with oil and gas spills.

It seems you can do smooth temporary patching of your floor.

I'm sure there are similar products but I unsure what they would be.
Top and Bond is a highly unknown and underused product .
Even though it is a temporary repair product if properly applied sticks like heck and lasts a long time!
