Well, I decided to have the floor done. Originally I was leaning towards epoxy, but you can't weld on it, and I really didn't want to have to use welding blankets every time I want to drag the welder out.
So I had the concrete polished. It took 2 guys from preferred concrete polishing about 12 hours to polish the garage, then they filled in the saw joints in the slab.
All in all, it looks great! I can't believe how smooth it is. Also, the floor had several uneven spots from when the slab was poured (which was obvious when I was watering it during the curing stage). Those are all gone now. Because of the unevenness of the floor, and the minor amount of bullfloating that the concrete sub did during the pour, you can see a fair amount of aggregate in the floor finish, but I rather like it.
Now the pics! :
During: This makes an incredible mess and generates a lot of concrete dust slurry when they're polishing/sanding with 50 and 100 grit "pads"
Finished:
notice the reflection of the lift. It's decently glossy, and not slippery at all, even when wet.
And a close-up showing some of the finished product with no and some aggregate showing:
I'm really pleased with it. It turned out awesome, and I get all the benefits of epoxy (spill resistant, no hot tire pick up, super durable) and I can weld on it. And It won't flake off! All for virtually the same price as epoxy professionally installed...
