MDF has many advantages over plank wood， particleboard， or high density fiberboard. Its very smooth because the wood fibers used in its manufacture are uniform and fine. This makes it have low tear out， which means that when sawed， the end has a smooth cut instead of a jagged edge. This also means that a coat of primer and a couple of coats of paint take well， leaving an attractive， finished surface unlike other composite wood products.
Can be nailed， glued， screwed， or stapled， making it as versatile as plank wood
Medium density fiberboard or MDF， is a composite wood product similar to particleboard， its made out of wood waster fibers glued together with resin heat and pressure， MDF is appropriate for many applications， from cabinetry to molding to shelving
Builders value MDF because it can be nailed， glued， screwed， stapled， or attached with dowels， wood fibers used in its manufacture are uniform and fine， which makes it very smooth， does not warp or split， and does not expand and contract like natural wood
Oil-base or latex paints can be used when finishing MDF boards
Excellent for interior use trimming windows， doors and cased openings
