I recently had a customer bring in a fairly large 44x68 map of Canada and wanted it wet mounted on foam core. We took the job and it seemed simple enough. I haven't done any wet mounting since college and when I did I used rubber cement or spray mount. My new employers use YES! paste... needless to say the map had wrinkles in it and the foam core bowed something awful. The customer didn't complain or call back but that doesn't mean he wasn't pissed.

I'm just looking for some tips on using pastes I guess to avoid any further problems. I did find out today that the paste they had was really old, he said maybe 3 years old, I don't know if that would have any effect on whether or not the print would do what it did. I am going to switch to Golden gel instead because I have been hearing rumors of YES! paste browning over time. Maybe this will fix my problem.

Thanks,

Welcome to the Grumble Tri-Dee Framer.
I have used Yes paste before, but only on canvases in certain situations.
Dry mounting would be the way to go on a map like that if you have a large enough press or can do it in sections, as long as there is no special value to the map.
 
Ya it is the standard now but we don't do enough mounting to warrant the purchase of such a machine! :shrug:
 
When I rarely get a piece to mount that is too large for the 40x60 heat vacuum press that we have (We can mount up to about 44x64 in it), I farm it out to a local graphics place and let them do it.
 
We are a a small shop in downtown MT. Vernon, we try not to send customers elsewhere but I wonder what the local print shop would charge if I brought them the mats.
 
When I have to outsource the mounting, I get a price from the graphics company which is sort of wholesale due to our relationship and bump it up to the client appropriately (and fairly) and when we frame the piece it's not really any more than if we mounted it ourselves.
I don't send the client there, I take in the work, pass it to the graphics company, get it back, and the client pays me.
They're not even aware that someone else did the mounting.
 
That sounds like a good idea. I'll have to get a quote from the print shop.

Thanks
 
Part of the bowing problem -probably all of it- is that only one side of the foam core got wet, while the other did not, so the paper on the wetted side distorted. Even if it were dried thoroughly under weight, the bowing effect would occur.

The same kind of warping will happen if you wet-mount to only one side of say, a piece of matboard, but if you paste a sheet on the back side at the same time, this can be avoided (the same holds true with wood, which is why veneers are always applied to both sides in good furniture).

These days most conservators say, "Say 'No' to YES paste."
