Title: Glass?
Post by: ArtByG on April 08, 2011, 01:25:54 AM
Should an acrylic painting be framed under glass? I don't put glass over mine, but someone asked me for advice. I want to give the correct answer. I would guess that if it is matted then glass would be ok. Please advise.

An acrylic painting that has been painted on normal canvas does not need to be framed under glass at all. It is treated similar to an oil painting as far as framing is concerned.

However, if the painting is on paper and is slightly flimsy then it can be pasted onto a strong board that is acid-free. This has to be done with special glue and by a professional with a vacuum press. You don't want the paper cockling at this stage and ruining the artwork. Otherwise it, because if its fragile nature, needs to be framed similar to a watercolor painting under glass for protection. One needs to keep oxygen from the back of the paper so that it does not oxidize and become brittle and become yellow with age. That's why watercolor paintings are sealed at the back of the frame.

I  have done it, as well a lot of other artists, and framed an oil or acrylic painting behind glass, not for protection, but for the expensive presentation it gives to the painting itself.

Would it be correct then to assume that a watercolour painting (back) should be sealed as well as put under glass? How would one go about sealing the backside?

Val you would use the paper tape or even packaging tape to seal the back. You would overlap the frame and the backing board when applying the tape.
