How come? did it come out bad? lifted?
No, didn't lift, or at least I wouldn't call it that.. It scuffs pretty easy. Maybe I am expecting too much, but I was hoping it would be a little tougher.
I also thought there would be more solids content in it, some of the industrial epoxies out there put down a 1/4" thick or greater layer, but the U-coat It puts down barely a few thousands (0.006" IIRC) of material at the area coverage they rate at.
You get a 5 gallon bucket to mix all of the stuff, but really, you get 2 gallons of material, with another quart or so of hardener/activator (don't remember exactly what it was). Oh aluminum oxide flakes (I didn't use them).. and some rollers. Granted the industrial epoxies are twice the price of UCI, but there are lot more solids in there, and they fill voids and cracks very well, leaving a better surface on older concrete IMO.
For $80-$100 or so, the Rust Oleum and QuikCrete stuff is basically the same amount of stuff (2 gallons IIRC), is water based (there is a urethane based version for $20 more), and with the money difference, you can spend up on crack/chip filler to get a better looking finish. All of the crack filler stuff was not included in the UCI kit, and adding it in was another $100 or so.
Upsides: I tore down 3 engines, and built one already in there. The light is better (more light reflecting off the floor), the cleanup is a snap. Some Simple Green and a mop cleans up oil, grease and coolant droppings, the only downside is that the light grey color shows all the dirt, so I find myself mopping the floor often to keep the shop looking tidy. I should also note that the shop space is tied directly to the mud room, and we let the dogs out the shop door to the yard, so keeping the floor clean so that the dogs don't track grease into the house is important to marital bliss

.
But, based on the scuffing I got from the engine stand wheels,I'm just not sure it was worth the extra $$ over the other similar coatings out there.. I don't know how it's going to hold up to sliding a jack around, and I hope it holds up well when I actually get a car in there..
My $0.02.. HTH..
If I have time this fall, I plan to coat half of my garage with probably the Quikcrete stuff. That will give a pretty good A-B comparison.
