Thanks for directing a comment at me, but you think I'm right only 99% of the time?
Yes in the past many years ago I did some tub surounds with GB when the customer didn't want to put down the right amount of $$$. I always told them that it wasn't the best way, but that was the method the other guys were doing. I don't think I've ever done a shower with GB, if I did, it was the old double wall method with a CBU over the GB. That's the way many jobs were done around here. Even today, most setters that do mudwork float 1/2" of fat-mud over GB. It's really not allowed by IBC code since Jan of 2006, but our State and city building department doesn't care about that.
Today knowing a lot more and having the choice of doing a truly good job by using the Kerdi Membrane and Kerdi Drain for example, I go in and try to sell them on having me do the job the right way. By this I mean the total shower package done the way it's supposed to be done. Almost every shower here is done wrong, and I tell the people. Some believe me and care enough to let me do the work. Others only want to know the price. Those people wouldn't hire me anyway no matter how I was doing it.
I'm trying to do good work and run this small business legitimately. The way things are going right now, I can say there aren't very many legitimate contractors around these parts. Many are not licensed, some use GB and mastic is wet areas, almost no one knows what a pre-slope is. Many work cheap and for cash which is not claimed. We also have an immigrant problem, these nice people come mostly from Eastern Europe, were brought here by their cousin, live with them and get little $$ for their labor. They can't even read the directions on the products.
Well.....what was the question again???
