Knotty pine

Overview

"Knotty pine" is a look, not a species: any soft pine milled to a common (non-clear) grade so that knots remain visible. It is the traditional wood for cabin panelling, country cabinets and ranch-style furniture, valued as much for its character as its low cost.

Pros

• Cheapest decent-looking solid wood; readily available as boards and T&G panelling.
• Soft and easy to work; glues and finishes well.
• Knots give a warm, rustic character that suits cabins and country kitchens.
• Light weight.

Cons

• Soft: dents easily.
• Knots can fall out, split or ooze resin; they also dull tools.
• Knots bleed through paint without a shellac-based primer.
• Orange when finished with oil-based varnish; yellows with age.

Variants and subspecies

• Usually eastern white pine (Eastern white pine), ponderosa (Ponderosa pine) or lodgepole (Lodgepole pine).
• Western grades: "Select knotty" has smaller, tighter knots than "common".
• Southern "knotty" stock can be harder yellow pine (Southern yellow pine).

Working and finishing

Work knots with sharp cutters; tear-out and chipped knots are common. Sand carefully; knots are harder than the wood around them. Seal pitchy knots with dewaxed shellac to stop resin bleeding through the finish. Pre-drill fastener holes.

Staining and finishing colour

Seal knots with shellac; apply a pre-stain conditioner, then a gel stain, or use a clear satin finish to keep the look. Oil-based varnish turns the wood orange-yellow, and the traditional shellac finish ages to amber, so expect the colour to deepen.

Sustainability and handling

Species varies; see the species entries for IUCN status. The Wood Database notes that working pine has been reported to cause allergic skin reactions and asthma-like symptoms in some people. Keep dust in check, and note that resinous knots can gum up blades.

Popular projects
