Poplar

A hardwood that behaves like a painter's dream

Poplar is technically a hardwood, but it is one of the softer ones — which is exactly why it is the trim and millwork standard across the country. It is dense enough to hold a crisp milled edge and soft enough to cut, nail, and sand without fighting it.

The reason people specify it is the surface. Poplar has a fine, uniform texture with very little grain contrast, so a sprayed paint finish lays down dead flat. There is no earlywood-latewood telegraph coming through the film a year later, and no knots bleeding tannin through the primer. If you want a wall that reads as a single painted plane with only the profile's shadow line showing, poplar is the material.

Color, stability, and what to expect

Raw poplar runs creamy white through pale tan, often with green, gray, or purple mineral streaks in the heartwood. Those streaks are natural and completely covered by paint — which is the point, since almost nobody clear-finishes poplar.

It is dimensionally stable indoors, holds fasteners well, and does not move much once acclimated. Standard practice still applies: let it sit in the conditioned space for a few days before you hang it.

Poplar is an interior wood. It has no natural decay or insect resistance, so it should never be used on exposed exterior work. That is what cypress is for.
