I'm thinking of coating the floor in my main garage. I spent way too long looking at information last night. There seems to be constant conflicting information. For reference I'm in the OKC area and the garage is a little over 1,100 square feet and it's for parking and some car cleaning. No real work happens in here. I just want it to look nice. Is there any definite answer to epoxy with polyaspartic topcoat vs polyurea with polyaspartic top coat? Seems like there are pluses and minuses to both. I'm starting think that the answer is best installer, but how do you really know. It's almost enough for me to say that my bare concrete looks amazing.

It's all about the existing slab and the installer. Manufacturers are not wanting a product to fail, but you need to pay for a good system that matches your needs.

If you need your garage floor done in one day, then the polyurea base coat will allow for that. An epoxy base coat will provide a thicker build, better moisture tolerance, and even better adhesion. The only drawback is that it takes an extra day to install and may amber (yellow tint) at some point if you are not doing a full color flake broadcast.I'm thinking of coating the floor in my main garage.

They both will perform well if applied by competent installers. The one issue that pops up from time to time with one-day coatings is an ongoing solvent smell when installers don't allow enough time for the base coat to off-gas. Don't trust installers who tell tall tales about epoxy base coats and make unwarranted claims about polyurea being 4x stronger and blah blah. They are just trying to talk you into what they do because they don't offer epoxy.
I’m not worried about having it done in one day. That’s nice, but durability and a nice looking finish are my main concerns. From my reading and searching, I’ve learned that epoxy can seep into the concrete capillaries and has a stronger bond to the Concrete, but is more rigid in comparison to the greater elasticity of polyurea. I guess there’s always a trade-off. I certainly won’t allow anyone to do the job without diamond grinding it to CSP 2-3 for epoxy basd and CSP 3 for polyurea base. It’s going to be 90s to 100 where I’m at for a while, which makes me a little bit nervous about polyurea
