Flat Stock Baseboard — Solid Wood, Square-Edge Primed Trim

Flat stock baseboard in finger-joint wood gives a room its plainest, most modern line — a square-edge board with no ogee, no curve, just a flat face that reads as Shaker, contemporary, or transitional depending on what's around it. It takes primer to a smooth, paint-ready face that needs only a top-coat to vanish into the wall, and the finger-joint body holds a brad without the crumbling that gives composite trim away on a job. Unlike the MDF flat stock most yards carry, this is real wood: it resists the denting that chips fiberboard in high-traffic halls and carries no urea-formaldehyde core to off-gas into the room. Three heights scale with the room — 4-1/2 inch for standard walls and apartments, 5-1/2 inch as the everyday workhorse, and 7-1/2 inch to anchor 9-foot ceilings and open-concept builds. Supplied in 10-foot lengths, it covers the floor's expansion gap and protects the wall base — cut it, cope or mitre the corners, caulk, and paint it like any premium wood trim.
