Alternative to mdf for pva mounting artwork
Hi all,
I'm currently pva mounting canvas prints onto 6mm/9mm mdf ready for painting over with acrylics,
having the odd issue with slight warping on the 6mm - 9mm seems better but I'm wondering if there
is a cheap enough alternative to swap to eg, dibond or similar sort of core material I could buy cut to
standard frame sizes and that will firstly alleviate bowing and ssecondly allow me to use frames with
a more shallow rebate??

Have you tried sealing the backs of the panels with PVA?
What size are the panels?
I would tend to go with 2.5 MDF. If it does bow you can flatten it more easily.

Re: Alternative to mdf for pva mounting artwork
pva mounted onto 9mm mdf then painted over and sealed with matt medium. Wanted to leave the back clean to avoid needing a backboard as it wont fit the rebate otherwise. Are you saying use thinner material then use a backboard to pull it back into the frame flat as I hadn't considered that?
At the moment my largest size is 20 x 26 aperture (want to go larger on occasion but for the moment this is enough of a problem)
Thanks

Re: Alternative to mdf for pva mounting artwork
Strictly speaking the backing board is now part of the artwork after the canvas has been glued on to it and if the backing board latdr get wrecked, that's now part of the artwork. Condition can be very important to the future value of the artwork. I think that a separate backing board has some merit, in many cases.

The board will bow if you only seal one side. It is shrinking as it dries on the sealed side. I think that is what Prospero was inferring.
Rather than fixing your work to an acidic substrate, having you considered learning how to stretch canvas onto stretcher bars?? Alternatively you could paint directly onto Dibond. This would give you many contemporary framing options, both hand finished and prefinished.
Assuming that you are an artist not a picture framer, have you had a look at Alan's (Geospectrum) website? He can supply ready made frames at a very reasonable price, bearing in mind that you would be buying from an experienced bespoke framer rather than supporting a mass production overseas factory.

Re: Alternative to mdf for pva mounting artwork
Yes I get that the board will bow if only one side is sealed but is it not the canvas mounted to it that's pulling it in a certain direction?
Stretched canvas not an option I don't like working on a flimsy surface and I've spent a long time perfecting my technique.
Its not bowing to the point that its much of an issue, question would be would it be better on 3mm mdf, pva coating both sides then using the backing board to push it into shape?

Yes. Why put unnecessary pressure on the frame by forcing the backboard to serve as a lever? That pressure will probably reappear as gaps in your corners eventually.
I would look at Dibond, like i said there any some great new options for float mounting dibond using high bond tapes onto metal subframes, st ives style frames or very slim prefinished mouldings from Lions.
