I've been working on a game table for a while now. and I was gluing down the pieces of foam core poster board to a big ol' 48" by 38" masonite board and the moisture from the glue caused the masonite to warp into having a big lump in the board. And I was wondering if anyone had ideas on how to try to unwarp it? at the moment it's just sitting on my garage floor covered in weights :P
Too late now, but next time paint the masonite first. Painting it makes a moisture barrier to prevent absorption and expansion. I recommend painting the bottom as well.
If you trowel on a thin coat of Liquid Nail there is no need to paint the MDF. The liquid nail wont permeate it. You can also use LN as a barrier for foam, so you can paint it - but it has to dry thoroughly.Originally Posted by RealGenius
Then ya' got any tips on getting the foam core stuff off it with minimal damage?
What kind of glue did you use?
Water will soften White/PVA glue other than that you're stuck with the damage. Good news is you can probably save the masonite. What you will do is strip the foam core off and build a frame on that side. On the flip slide use wood putty and smooth the the remaining warp out. Prime and then you'll be good to go.

Does anybody else find it odd, by the way, that the information age has led to language becoming an oblique and imprecise tool where even the most straightforward phrasing is pored over with chicken entrails and bone tossing to divine the true meaning?
Yeah I used just pva glue, but I can't seem to get the foam off. And I really don't want to just trash what I have so I was wondering if attaching the whole thing to like another layer of masonite/particleboard would work to straighten it out?
Your at a loss now. You could try building a frame on the other side but I doubt it will pull the warp out.

I second the frame idea, use screws to attach it. Maybe a frame of 1x2's.
And use wood glue to hold.
