Hey Guys,

I wanted to reach out and see if any one has experience mounting a larger sized UART paper (~40"x60") and what their process was for a). mounting that size b). the substrate used.

I've been digging around and doing research on how to go about mounting paper this large but am a little confused. According to customer service at UART, they recommend 'Dry Mounting' with Graffix Double Track Mounting Film. However after looking into this it appears the largest size is 24" x 36".. So it would appear I would have to use multiple sheets. Does any one have experience doing this? Or would a Cold mounting method be more applicable? If so what do you recommend?

I am debating using either Dibond panel or Gatorfoam as a substrate.

Any information or feedback is greatly appreciated. Thanks!

If you have access to a heated dry mount press you can use various films that do not have a tissue carrier in them to mount a sheet that is larger than the dry mount film. They are pure adhesive and any overlapping of film will level out in the press. Beva 371 is one example that is also one of the more popular ones out there. Versamount is another. Some people have been successful using a regular home iron to mount surfaces with Beva 371 film, Lamin-All and others.

I started out trying spray mounting materials and brushed on liquids but was not happy with the results so I bought a used dry mount press. Had I tried the liquid brush on / heat activated adhesives I may have forgone the press purchase but I am glad I have it. Over the last few years I have had great success mounting pastel and watercolor papers, canvas and other surfaces to sealed hardboard and aluminum composite panels (Dibond) with heat activated dry mount films. I prefer aluminum composite to any available support surfaces but it costs more than hardboard and is heavier than Gatorboard.

Beva 371 film comes in 27" and 54" wide rolls.

Beva 371 solution is a liquid version of the film. As I recall, once it is dry it is essentially the same thing as the Beva 371 film. Another similar product is Lamin-All. It definitely won't be as easy as the film with a press but the link labeled Lamin-All makes it look fairly easy.

Some videos below mostly mounting linen but the process is the same for pastel papers.

contumacious- Thanks for sharing this information. I have been looking for something I could use for mounting Uart paper onto illustration board. The process sounds very easy. I like that the film isn't activated until you use heat.

I have two questions. Will the Beva film hold up to a watercolor under painting? Will it hold up to an under painting using rubbing alcohol?

Again, thanks for sharing the links. I see that they ship to Canada, so I am ready to place a order.:thumbsup:

Doug,

I use these materials to mount watercolor paper to various surfaces and they often get totally saturated with water, so yes, with pastel paper you shouldn't have any issues with water.

I would call the the Beva 371 people to see how well it holds up to alcohol. I have used alcohol in underpainting with EZMount and didn't have any problems, but I didn't keep the paper saturated for very long. The specs say it is soluble in hydrocarbon solvents such as naptha, VMP and toluene. Those are significantly more aggressive than alcohol.

I don't have any Beva 371 on hand right now to test with alcohol, but do have some EZMount and some Polymount removable. I put strips of each film into 70% isopropyl alcohol for 20 minutes and could not detect any softening or dissolving plus once dry they adhered as expected to some card stock with my tacking iron.

I have some strips soaking in OMS and will report back on that test.

contumacious- Thanks again for the info. I think I am going to order a roll of the Beva film and try it out. I also paint in watercolors and it sounds like fun to make my own watercolor boards.

Doug - You are welcome. I think you will be pleased with the results. I can't bring myself to do watercolors or pastels anymore on unmounted paper after experiencing the difference. The mounted sheets also make framing significantly faster and easier for me. Zero worries about the paper slipping in the frame, perfectly flat, no warping or cockling that shows up later and no backing board needed in the frame.

Just make sure your support board is resistant to whatever "solvent" you use, be it water, OMS or Alcohol. I coat all sides of tempered masonite with either gesso, XIM or PVA before I mount papers. Dibond doesn't need any preparation from my experience. I have never used any Gator board or foam core, but they are liked by many. Be sure to use a cover sheet if you are using a regular iron. In a press, the silicone release paper works great.
