Medium-density fiberboard, or MDF, is a manufactured wood product composed of wood fibers that are mixed with resin and wax and pressed into flat panels under high temperature and pressure. It is used much like plywood as a building material. Unlike particleboard, with which it is sometimes confused, MDF cuts well and has a smooth surface that is ideal for painting.

It is best to cut MDF outdoors, as it creates a lot of dust. It is also smart to wear a respirator when cutting or sanding MDF. When exposed to moisture, unfinished MDF can swell and lose strength.
