That's right. Or real urethanes, or MMA. They're made to survive food manufacturing, chemical plants, airplane fuel, etc., so a little booze won't do a thing. Surface prep and humidity matter a lot,and materials costs might be $5/square foot, or more for small areas, which turns off someone who has in mind that you're going to mop on some garage floor paint overnight and they'll be slinging beers the next day. MMA if you want a quick turn-around.
I can't pretend to have a long track record with this - I have only one MMA project under my belt, and a couple more in the pipeline. I did a lot of research, though, and have been looking in every restaurant kitchen possible, to see what's on the floor. It appears to me that these coatings are taking over commercial and institutional kitchens - no more quarry tile.
Not that you asked, but the way to sell these is on durability. If it's installed right, they won't be paying some guy $500 to scrape the paint and crud off the bar floor every few months, and repaint with another coating that will fail. Cleanable as anything.
What with the quartz and other color additives, some of these are very attractive, too.
Buy the REAL DEAL of epoxy coating and you will be fine. Buy a gallon or two from a Big Box and it WILL fail.
