Topic tags/keywords: question frame backing hardboard

I’ve got a question about what everyone uses for backing on frames, shadow boxes, etc. When I built my first shadow box, I used foam board for the mounting and just cut out some hardboard for the actual backing. I made some more frames to put awards in and continued with the hardboard. Is there likely to be an issue with this? Should I be using some type of acid free backing or barrier between the two or something besides hardboard? I have a friend who wants some frames for Blue Angel pictures but want to make sure I’m not going to use something that will eventually ruin the pic. Thanks in advance for your help.

For shadow boxes I use 1/4” Luan. My wife use a type of foam board with adhesive to mount her counted cross stitch to so I can mount them into frames. You can get this at Hobby Lobby or any crafts store. Don’t know if that helps any.

I’d pose that question to a frame shop or maybe there is the LJ equivalent in that realm. It will feel good to know for sure.

For picture frames, I use acid free foam board. For larger shadow boxes, a piece of 1/4” plywood/luan as the actual back but add a piece of acid free foam board or acid free mat as a separator between the articles and the wood..

For regular frames, I don’t understand why you need any backing other than the foam board. That’s all I use.

For smaller stuff I use foam board. For the larger stuff, I use multiple layers of foam board primarily to keep it from warping. So far, it’s worked OK. Check back with my grandkids in about 30 years. ;)

Since you’re talking about mounting actual pictures, you should seriously consider useing acid-free mat board to keep the glazing (glass or acrylic) from contacting the picture or they will likely, at some time, become one. I understand this has nothing to do with the backer board but it will definitely ruin the picture.
