Roger, the guys on the forums tell me that hot mops are still king in socal. I've never seen one in person. I did tear out a few showers from the 1950's that were nothing more than a few layers of roofing paper :yikes:. I'm amazed that they lasted as long as they did.
I don't know anything about the poultry netting. Again, that must be a East Coast/West Coast thing. The only times I have seen it have been in books and videos by Michael Byrne.
I agree with you about Hydroban-we go with three coats and usually with fabric in the corners, even though Laticrete says otherwise.
