I have just installed this product, and have a few hundred more yards to go in Newport Beach. I'm still not sold on my method, and I hope to perfect it by the end of the big job.
Here's what I've discovered: It needs clay adhesive, but any you let get on the seam areas WILL discolor the seams. It ain't going away after that. So I switched to Dynamite 234, whipped up with no water in it to preserve it's full tack. On the walls I rolled on a heavy coat of 111 clay at the seams, and around all woodwork where the paper ends, and let that dry. I tried it with 234 on the seams and still struggled with getting enough tack.
Here's where I'm not 100% sure yet, but my results looked pretty good (90%). I hand pasted it with 234, booked it, and trimmed it wet with my straight edge on the table. The seams went together really nice, but there was a slight creasing at the folds that was discernible in some light.
I'm hesitant to double cut this material due to how heavy it is. I'm afraid so much pressure is needed that I will risk cutting into the walls in places. There are products that help that, but fraying is also a problem if you don't cut cleanly. I'm not a big fan of the double cut in most cases.
In about a month I'm going to start the big job with it, and I think I'm going to pull it through my Pastewell 56" machine to speed up the pasting. Then I'm going to coat all the walls with caly to see if the creases go away upon drying. Tack might be the solution for that. I will also try putting a razor blade at the 2 ends of my straightedge to see if that helps reduce the creasing. If I'm not satisfied with my results I'm going to dry trim it and hand paste the whole lot, doing it the slow way. It has to be right.
I don't think the stuff is all that attractive, because it's just like sparkley white paint. It's a PITA to hang, and I can hardly wait to have it behind me.
