In all the shops I've worked, we have always used foamboard to mount artwork. When we had conservation jobs we used conservation foamboard. Is there a right or wrong thing to use? What are "mounting boards" (as seen in the Larson catalog). Are they more like matboard? As, what is "needleart" board? and news board?

I have all of vivian's DVDs and books but I have not read/watch them all yet. Even so, I'd like to hear folks opinions. Thanks!
 
personally I prefer to mount on a mount board first, then back with foam core. I have found that foam core will sometimes break down in spots (from the heat) and leave slight impressions or divots, the odd time if you forget to run your hand over the board there will already be a divot in the foam core. it's hard to mask these marks too.
 
General mounting board is like Crescent 3x which is standard paper board. News board is also referred to as chip board and is carp. The junk at Wally World is mounted to chip board.

Conservation boards are designated as Alpha or acid free and of course rag.

P.S. Not all acid free boards are conservation quality
 
From "Conservation Framing" by Vivian Kistler

"The backing board ...

Use the same type of board that was used for the window mat to crate the backing board. If the window mat is made from 4-ply rag board, then the backing board must be made from 4-ply rag board. If the art is particularly heavy, it is appropriate to use 8-ply backing for more support.

Do not use filler board materials as backing boards.
Always use the same quality board immediately behind the artwork as was used for the window mat."

I always use 4-ply for hinged artwork even if not "necessarily" conservation for much the same reasons of quality and surface texture.
 
so, just for my knowledge....when do folks use foamcore? for drymounting posters? or do those who prefer mounting boards use them for everything? Would it be acceptable in a conservation job to mount it on the conservation "mounting" board, then use cotton rag foamboard as a extra protective filler?
 
I use foam (different kinds for different purposes) for drymounting, filler board, mat floating, shadowbox buildup ... that kind of stuff.

For conservation filler I usually use coroplast, but also use Artcare Foam at times. It's been a while since I checked the literature, but as I recall, some experts feel Foam still has potential problems, but the CCI (Canadian Conservation Institute?) considers A/F Foam an acceptable filler. But, never use clay coated (I forget why, but it's bad)

Click to expand...

Cliff and the others are correct in their discussion of mount boards, but foam center boards are also mount boards...just not acceptable mount boards for when doinf preservation (conservation) mounting. Chapter 2--Understanding Materials--in each of my mounting books fully all types of substrates--the boards items are mounted to--when to use, weight to use, et al. Everything from low end chip boards to aluminum composite are covered.

Also Hugh Phibbs had an excellent article in August PFM--Picture Framing Magazine--on backing and filler boards. FYI: foam center boards have been officially approved for use in framing enclosures as found in the newly passed ISO/ANSI standard ISO18902.

For additional information on books, ISO18902 or anything else feel free to email me directly.
