Concrete Slab Skim Coat for Garage

Disclaimer: First Posting. Hoping for success.
Question: I am contemplating a skim coat of concrete over my two car garage concrete floor. The existing floor is in good shape; however, water from snow melt does not flow to the floor drains and therefore create large puddles on the floor.
What is the absolute minimum thickness I could get away with and still have confidence it will not crumble under the weight of a couple standard passenger vehicles? Thanks, TCM.

It depends on what you're skimming it with. Whatever product you use will have instructions on the bag, including application thicknesses, etc. Don't just try to use a sand topping mix, because that will crack and flake away in short order. Whatever you use will have to be a polymer fortified concrete mix of some sort. It will most likely require an acid etch, and a primer coat before application. Good luck.
