Trim Material Options: Bare Wood
With a trim project you’re going to have to decide what types of trim you want to use. A good place to learn the types of trim is Lowe’s glossary. They are bare wood, primed wood, medium-density fiberboard, polystyrene and PVC trim. You should use bare wood if you want to stain it or have a natural wood look. The type of wood you can choose from usually ranges from poplar to pine to fir to oak to aspen.

Primed wood trim is sometimes cheaper because you can use less expensive wood and use finger joints to join shorter lengths of trim. Some of the headaches of go away versus bare wood. Primed wood will cut the installation time since you won’t have to wait for the primer to dry. It’s easier to spot defects and nail holes on primed trim, so you can fill them before the final coats of paint. It’s even simpler to cope primed trim because the contrast between the raw wood and the painted surface gives you a crisp profile line to follow. So don’t buy raw wood if you’re going to paint.

Medium-density fiberboard is a popular option for trim because it’s typically the cheapest. It does come with its own set of issues, though. MDF won’t perform as well in wet, humid areas. MDF (medium-density fiberboard) is inexpensive and a great material for painted trim, but only if you’re installing it in a permanently dry place. Installing it near the floor or near windows where water or condensation sometimes collects is a recipe for disaster. The MDF will soak it up like a sponge, expand and shed paint in very short order. So avoid using MDF anywhere at risk for getting wet.
