Got to frame 2 original paintings... acrylic on mountboard... and they are so wavy. A good 3" curl and i'm having a nightmare getting them to lay flat without gapping around the cutout.

Using 2.5mm mdf as a backing and still NBG! Also tried 2 layers of backing ..



Help appreciated.

Sounds like they have been painted on a totally inappropriate surface.

When will artists learn there is nothing to be gained by trying to save a few bob.

I have first hand experience, being married to an artist!

It's gapping about 4mm all round so short of backing it with 6mm mdf I'm not sure what else to do.

If it won't flatten, can the wavy nature of the board be made into a feature - float mounted with an inner frame around / or sink mounted?

I've seen them curl round so much they are cylindrical.


One way is to paint a similar thickness of the same paint on the back and leave it for a few days.

It does work, but not something I would do without permission from the artist.


(better still, tell the artist to do it. If they are still at large)

Sorted... found a scrap sheet of 4000mic board. Held it flat to glass and no bulging.

That's terrible. I agree with Gus.
