How do you flatten out the "bumps" caused by water on mdf? I have an end table that I bought that has water damage and even sanding it does not remove the "bumps."

Personally I dont think you can. I have tried steaming mine then clamping it between two pieces of wood for a few days and it just bounced back to bumpy. I have also tried putting it through a thickness planer which did not work. I have had some success when I have used it on a shelf and i have been able to nail it flat all the way around. You might be better off just getting some new pieces.
Not possible, when MDF gets wet and expands there is no way to shrink it back again.
That's what I was afraid of. Thank you! I won't waste any more time on it.
Its not reversible, but depending on what kind of furniture it is —and where it has swoolen you might consider resurfacing it with a thin layer of wood veneer or maybe tile. Could you post a photo?
