Hey Tom, great write up in the paper. You'd better get a wholesale deal on candy for next Halloween though!! Kinda funny, we left our "city" neighborhood home to come out to the suburbs. Our halloween count went from 7 in 2001 to about 80 here in the "country".

As for the epoxy floor. Mine's only been down about two months, but so far so good. It had a full 3 weeks to cure before I put anything on it (cabinets, tools, car). I've drug my table saw across it, some of the cabinet units, and rolled some steel wheeled tools over it, and no signs of lifting. Some light surface scratches that rubbed out fine (I'm not that anal, just curious if it would make a difference or not). The U-Coat-It isn't your only choice. I got the Rustoleum kit at Lowe's. Home Depot sells it too. They claim about 250 sq. ft. per kit (one gallon), but I actually got close to 300 coverage, perhaps because my concrete was "fresh" and somewhat smooth. They include a floor washing material that contains citric acid for a mild etch, and don't recommend a muratic acid wash. They don't include, and therefore don't charge for, the bucket, googles, gloves, etc. that U-Coat-It does, but I had that stuff anyway. The cost here was $55.00 per kit, so that works out to less than .20 per foot! Of course I provided my labor, which some say is worth just what I pay for it. The clean up prep is the big part of the job. I ended up with essentially four washes of the floor prior to coating. Like the U-Coat-It, the Rustoleum cleans up with water......until it kicks, then it's tough stuff. Pot life, including the 1 hour induction time, is only 3 hours, so, doing it with a roller means you can't delay too much. With as much area as you have, spraying might be better, but you'd need to be mindfull of the pot life so that the material would still be water soluble for clean up. As for the prep, that might be a good place to have a pro with a high pressure washer do that messy part to cut down your labor, plus that would get rid of most, if not all, of the grundge you indicated was there.
