I installed the coin flooring yesterday only to turn around and uninstall it. After repeated calls to the manufacturer with no replies I opted for weld wood contact cement,since I'm familiar with it and have always had good results.
The install went great no bubbles in the flooring and it laid down really nice. But when I came back a couple hours later there were bubbles all in the floor and it was almost like it had softened the floor or melted it somewhat.
I rolled it back out again but it was no use the bubbles kept reappearing so I stripped the whole sheet out and laid it out to dry.
This morning I called the manufacturer and I was able to talk to tech first thing without having to leave a message (go figure). He advised that the weld wood wasn't compatible with the flooring and I should use wf Taylor 2091 adhesive.
So what I'm thinking now is cover the existing plywood up with maybe Luan and try this again.
Not real sure why I didn't do a test piece first
