Medium-density fiberboard—most often known by its initials, MDF—rivals the affordability and versatility of plywood and similar engineered wood products. In certain situations, MDF even trumps all the others, because it’s so wonderfully easy to work with. Unlike real wood, MDF has no knots, grain, or warping, and its smooth surface gives way easily to the saw, leaving no splinters, burns, or tear-outs. For light carpentry projects, such as shelving and trim, MDF can be excellent.
MDF starts as sawdust and shavings—all the little bits and pieces of wood that are created as a byproduct of industrial milling. Once dehydrated, those wood fibers are then mixed with resin and wax and formed into panels. Under high heat and intense pressure, those panels are compressed and become rigid, with a hard shell. In the final stage of manufacturing, giant machines sand the panels down, giving them a silky smooth finish before cutting them to fixed dimensions.
MDF boards are typically tan or a darker brown and are sold primarily in either 1/2-inch-thick or 3/4-inch-thick sheets. Depending on where you live, the largest- and thickest-available sheets should cost you no more than $50. Also, important to note is that an MDF board may be marked or stamped to indicate a particular property. For instance, blue or red marking means that a board is fire retardant; a green marking indicates that it’s resistant to moisture.
Working with MDF is the same as working with real wood. You don’t need any new skills or special tools. In fact, you are likely to find that, compared with sawing and attempting detail work with solid lumber, MDF is much more pliant. For smaller projects, such as bookcases or cabinetry, it’s user- and budget-friendly. Plus, its surface accepts paint well and also provides a welcoming base for a thin veneer layer.
