Another thing to consider is the labor savings using the HCT product over conventional poly. From the IF website:
"The result is TRUE Green Poly™, a substitute for conventional polyurethane and epoxies that is hundreds of times less toxic, has superior properties, and may provide up to 30-60% in reduced application costs."
This product can usually be applied with only one coat, as opposed to a primer, base coat and top coat.
I work for a large construction contractor and any product that states there could be a 30-60% savings in labor is definitely getting my attention. If a job turns to crap, it's usually always because of labor over runs, not material. We pay more for certain products because we know that in the long run, they are going to save us labor. The old saying is true...time is money! This especially true for projects that can't be shut down for long periods of time and that operate 24/7.
So, just saying that this product is really expensive isn't being objective, nor is it looking at the whole picture. IMHO GLTA Longs
