Unbranded 0.591 in. x 6.000 in. x 8 ft. Primed MDF Shiplap Siding

MDF has many advantages over plank wood, particleboard or high density fiberboard. It's 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.
