I have a rolled poster that is very fragile and I don’t want to potentially crease it. I also can’t use heat or water as its sharpie signed. It’s not super badly rolled but it’s certainly not flat.

So two questions, can I mount it to a mat in the current situation or do I need to flatten it perfectly? And if so, how do I mount it? I’m afraid any kind of tape may permanently damage it.

    Is "mounting to a mat" the only option you've considered? Are you open to other options, or have you ruled them out?

    You could have it professionally framed under glass (without mounting), using a frame shop with experience handling delicate items.

    It really sounds like you're starting from a point of zero knowledge; it's incredibly rare (largely unheard of) that a frame shop would frame anything directly touching the glass. I would strongly recommend talking to a professional shop about how to handle this, instead of trying to do it yourself.

    It is certainly not "too late" unless you damaged or destroyed the poster with your own efforts. Again, please consult with a professional, as your lack of knowledge of framing is a far greater threat to damaging your item than anything they would do.

    Why don't you want to dry-mount it? And I assume you intend to glue it to a backing board (and not a mat in the sense of a passe-partout)? If that is the case, it's even easier to not have it touch the glass. Also, again, what material is the poster made of?

1 Answer 1


I would glue it on a wood pannel (multiplex), because else I'm afraid it won't stay good (a mat will extend and shrink a lot with humidity)... To glue it, use for example upholsterer's glue, but it also depends on the kind of paper. I would try on a little corner before.

    Wood also expands and shrinks with humidity, and upholsterer's glue sounds like a great way to do significant damage to the item.
