Can you restain wood panelling?

If the paneling is real wood, it can be restained easily. You would need to lightly sand it, and then stain it just as you would any other wooden surface. If the paneling is laminate, you would go about it in the same manner but may find that the stain does not penetrate the surface of the material as easily. So, for laminated paneling you might want to try a test area first.
