Repair water damage from composite wood/particle board?
I just bought a used wooden bedframe. It looks to be made from particle board or composite wood. When it was delivered by the owner, it was raining so a small part of the headboard got pretty wet and soaked up some water. The wood in a small section has swelled slightly and the corner piece looks like I could just pull it off. Im wondering how I can save/fix this? After letting it air dry, would I be able to maybe add some wood glue underneath the parts that are swelling/curling up put use some weight on it until the glue sets? Since its only a couple of small areas with damage and its not a spot that will need to support any weight, I'm just looking for a quick and easy solution to "hold it together". Plan on painting the entire bed frame with white chalk paint. Any suggestions or advice would be greatly appreciated! Thank you!
