I am making an extension wing for a tablsaw using MDF. I gluing Formica to the surface using contact cement. It will be screwed to a frame made of 3/4" x 2 1/2" maple boards. If I don't seal the bottom of the MDF, will it warp? My basement shop keeps pretty dry. I know the MDF will absorb moisture faster on the unsealed bottom making it warp, but the question is, will the frame boards be stiff enough to overcome that tendency?
Thanks,
Bill
