Please help!!! Over the winter, we decided to redo our living room. We took out all of the old paneling, put in a new ceiling, etc. Anyway, we bought primered fiber board, painted it and put it up, attaching it to the studs. We bought beautiful crown molding and stained it and installed it. It looked just beautiful!! Welllll, the fiberboard has now waffled, it is all uneven and looks terrible. We are both just sick about it. We spent quite a lot of money and now it looks like it was all for nothing. What can we do???? Can anyone help?
