Why does the (painted) MDF covering of a stage bulge and warp?
Posted by Brian Fairchild You should have left an expansion gap. Any wooden floor will grow and shrink as the humidity changes. If using 4 foot square panels something around 3mm gap will be needed. Posted byOwen Jones MDF absorbs paint, if that paint is of the sort that contracts to give a tighter cover or is water based then the MDF can bend and curve. Specify when you buy the paint that you want paint for MDF or cover then MDF in a sealant.
