Hi,

I have two questions relating to dry mounting.

1. A customer brought me 16 small oil paintings. These are too small to stretch and I don't think a hinge would hold them. Dry mounting them came to mind. I have done it before, but the oil paint wasn't as think as this one. Has anyone done this or can anyone offer advice on this?
(I know not to dry mount original art, but these were relatively cheap and the customer just wants it to be permanent.)

2. I am having problems with the dry mount press leaving pressure marks. Its not indentions from something on the board. It looks more like its changing the surface of the paper inconsistently. The paper is a fiber based pearl surface used in pigment printing.
I used to use release paper between the board and the art, but that was leaving similar marks. Our previous framer told me he never used release paper and that using just the release board would remedy this.
What is the best way to dry mount in order to alleviate this problem.

Thanks
 
The word small is not very defining.

So what size did you say they were?
 
A PVA adhesive such as Franks or LaminAll would be very easy used wet rather than heat activated.
 
To address the OP question number two:

I solved the denting problem by using release paper under a sheet of flaw board (or something thin, 4-ply and smooth) - solves the problem especially when multiple bites are needed.

Just make sure your item to be mounted is completely covered by the cover sheets. Or you will really see some marks!

I would use Frank's to adhere canvas to something like gator board to prevent warping. I used Frank's on a painting that was 24x48 - worked like a charm! Just had to let it dry under weight.

(Not compensated by Frank's - ;) )
 
I would use PVA and put them between two solid boards with a few books on top and leave overnight.
Release paper on top, but a foam blanket on top of the release paper will even out the pressure.
 
Jeff and Prospero have both offered suggestions I would favor.

1. Use a water-borne adhesive instead of heat activated or pressure sensitive adhesive. Fabric adhesive, YES! Paste, Laminall, Mighty Muck, etc. would all work, and so would PVA. However, if chemical stability is an issue, I would use acrylic gel medium or Lascaux 360 conservation-grade adhesive.

2. Set up under padded weight for a couple of hours, then remove weight and allow to dry in open air overnight. The reason for removing the weight is to avoid trapping moisture from the adhesive, which could penetrate the substrate and possibly foul the paint layers' bond with the fabric substrate.

I once left a glued canvas giclee under weight overnight. Next morning, the adhesive was still not dry, and moisture had penetrated the entire thickness of the giclee. When I removed the weight and white paper overlay, a slight ghost of the image had transferred to the paper. The image was still intact, but I felt lucky to learn that lesson without having to replace the giclee. It would have been easily replaceable -- in our shop we would not permanently mount items that are rare or valuable.
 
To clarify the size of the oil paintings, they are about 10x15".

Thanks for all the responses.

I will look into wet mounting. I also have a highly tacky tape used to mount needle points. Has anyone ever used it before on a canvas??

As for the dry mounting press leaving pressure marks, I will return to using release paper between the release board and see if that helps....

Thanks again and anymore advice is always welcome!!!!
 
Doesn't anyone use Yes paste anymore?
