In Reply to: Question About MDF and Humidity... posted by ArthurPrince on October 14, 2005 at 04:46:59:

MDF is usually OK if it isn't exposed to liquid water. It may swell a very slight amount in high humidity, but it won't become weak. But if you put a veneer on it, the slight swelling is sometimes just enough to see a ridge forming under the veneer at the seam of butt joints after a period of time. This can be solved using mitered joints so that the only seam is at the corner.
