I have a piece that i did some painting on and yup it curled pretty bad towards the paint side, anyway to straighten it out?
 
Lay it face down with a weight on it for a week or two, then use non stretch duct tape across the back in a cross from diagonal corners. Been there lol

In future ‘brace’ the back with the tape first.
 
When using canvas boards i heard that painting an X on the back stops them bending never tried it myself but a similar thing.
