"String" grasscloth

[TimO]

Need some help on this one! I am hanging a Gramercy "Shay Swirl" (pattern #545010) paper. This pattern has random curved strings of grass on the front. When glued and booked, the back of the paper (which is NOT very thick) expands while the front cannot expand because the random strings of grass will not allow full expansion.
This is causing the expanding paper to have no place to go except to "pucker"/wrinkle off of the strings on the front.
I have also tried the manufacturer suggestion for dry-hanging ( sponge-dampening and booking the paper before applying to the wall), but the results are about the same. Even tried putting up the paper dry.
Schumacher says that this paper will NOT end up being flat, but their suggestion for using a blow-dryer and seam roller to take care of those wrinkles is just plain unrealistic. I have even hung a test piece where I misted the FRONT of the paper to try to get the grass itself to relax a bit (yes, I know it's not recommended).
Personally, I think that the paper itself is just not thick enough and doesn't have enough body to limit the amount of wrinkling, but I am open to any suggestions!

What adhesive are you using on the grass-cloth? I have had good success (and minimal puckering) using Romans 880. It's a pre mix and low moisture product. Your problem seems to be excess moisture.

Thanks for the suggestion!
Roman 880 is the glue I used (I like it because it has good holdout and is excellent for dry-hanging grasscloth). Even dry-hanging it, as soon as the paper hits the glue, it puckers almost instantly since the backing paper has no body to it
The only luck I had was when I misted down the front of the paper before dry-hanging, and misted it again after it had been on the wall a while, smoothing in all directions with a smoothing brush...gets most of the puckers (not all, since some of them are big enough that they "fold over" no matter what you do).
If Schumacher continues this type of paper, I hope they at least double the thickness of the backing paper so it can be dry-hung with a minimum of problems.

One additional suggestion...have you tried liner paper? The issue seems to be excess moisture. I have experienced similar troubles with Mylar. The moisture can't escape from a painted or primed surface but a layer of liner seems to do the trick. Just a thought. Look forward to your response;)
