I didn't know Ucoatit sold commercial product or to the trade for that matter. Do they sell you the same DIY formulas or a different system?
Also, what type of work do you do? Is it mainly garages? Where can we see some of your work? Thanks
WARNING...WARNING...Thread Hi-jack in progress......
I don't want this to sound like a plug for me, the company I work for or the products I use, but I'll answer as thoroughly as I can.
Ucoatit told me that the same products they sell in their DIY kit are the same products they use commercially, no variation in formulas. Thats what kinda sold me. They do offer more types of products to contractors or repeat users than they do with the average home owner, and the system is based on what type of use the coating will see. The basic is two coats of a low build, with a high gloss urethane option. This seems to be the standard and is comparable to other products, although in my personal experience I think it works better and lasts longer. I get a contractor discount through them, and since they're local, I can get product easier and bend their ear when needed. I also can get high build (100% solids), and aggregate or trowel down systems as well for more custom work.
I'm a partner (junior) in a small home home improvement business. We do do more residential than commercial, but over the years or so have expanded more into this area. I mainly do residential garages and basements for customers our company has worked with before, although I have done and continue to do commercial areas as they come along. I guess the biggest I've personally Installed was about 6K s/f for a print/sign shop on there mfg. floor. High build, high gloss. When there is a floor that needs installing I usually get the call. At first this was done because I drew the short straw, and nobody really wanted to work with the chemicals in epoxy application, but now I enjoy it more.
I live and work in metro Detroit area. We've never printed advertising and all work has been referalls- no bull! I will canvass a neighborhood we're working in, but that's about it. Word of mouth is the best advertising! I may seem like a dinosaur but don't have a portfolio or anything really, I usually just use the mfg. marketing materials. I
KNOW I need to start taking pictures of every job in detail for such a thing, but we just finally came to agreement that we should put up a website! I'm trying to get out of the stoneage and into the 21st century. Since it's winter I'm working it out and this year when business rev's back up I plan on detailing our jobs a lot more in photos to show.
I'm also not as comfortable showcasing my work in detail- not because I have anything to hide or its quality, I just don't like tooting my own horn or seeking praise, I try to remain humble. (That and silly me really doesn't have all that documented well!

My buddy gave me some photos of the job we did at his motorcycle clubs polebarn a few years ago, so maybe I'll post a picture or thread of that install. I scanned the pictures so they're not great, but may help.
Thanks
P.S. Garageguy, I think you do excellent work and could learn a few things from you, plus you have that New Jersey no bull attitude!
