Engelmann spruce

Overview

A very light, pale mountain spruce from the Rockies. It is the western SPF spruce, with small knots common, and is occasionally used in place of Sitka for guitar tops (Wood Database). For furniture it is a cheap, clean painted-wood option.

Pros

• Easy to work as long as no knots are present; glues and finishes well.
• Very light (385 kg/m3) with fine, even straight grain.
• Cheap as construction lumber.
• Used occasionally in instrument tops.

Cons

• Soft (390 lbf).
• Small knots are common, which can chip.
• Slightly resistant to non-resistant to decay.
• Blotchy under stain.

Variants and subspecies

• Western cousin of Eastern and northern spruces; the premium western spruce is Sitka spruce.
• Sold in SPF lumber with Lodgepole pine and True firs.

Working and finishing

Easy to cut and plane, but small knots can be hard. Keep edges sharp. Pre-drill in thin stock; glues well.

Staining and finishing colour

Closed pores make spruce stain blotchy and inconsistent; the Wood Database recommends a sanding sealer, gel stain or toner when colouring it. Clear finishes and paint are the easy routes.

Sustainability and handling

Not CITES-listed (Wood Database; checked 2026-09-30); IUCN Least Concern as of 2026-09-30. The Wood Database reports that spruce (Picea) has been reported as a sensitizer, with skin irritation and respiratory problems the usual reactions, although severe reactions are uncommon.

Popular projects

Shelves, shop cabinets, painted furniture and crates; occasionally guitar and other instrument soundboards.

Buying notes

Sold as construction lumber in the West. No retail listing was opened for this species, so the range shown is an estimate. Quartersawn clear and instrument-grade pieces cost much more (Wood Database).
