This was sent to me by Decor E-tips. Is this right Hugh and Rebecca or what? I thought we said it was good to cover the back of paintings. As long as it is dry? Tell me what I am forgetting...Hugh forgive me, the notes from the framing class are around , but not under my nose at the moment.
7. The back of a framed oil painting should not be sealed with paper. It should be open to air circulation, but at the same time be protected against possible damage. Corrugated cardboard is not strong enough and hard fiberboard, such as Masonite, has been found to be too brittle to afford good protection. For small and medium-size paintings, a sheet of heavy chipboard may be used, providing the board has been sealed with varnish or shellac to prevent moisture absorption. For larger paintings, a thick plywood called doorskin makes an ideal protection. It is light and extremely resilient. Several holes of about ¼" in diameter may be drilled into the board near the top and near the bottom to ensure adequate air circulation behind the painting. These holes may also be covered on the inside with some gauze or cheesecloth to act as an air filter and to prevent dust from seeping in. Hard rubber bump-ons placed at the bottom behind the frame will also contribute to better conservation in allowing free access to air between the painting and the wall
