Alder is a soft, fine-grained hardwood from the Pacific Northwest that has become extremely popular for cabinetry. Its even texture and warm tone make it an excellent canvas for staining, and it readily accepts finishes that mimic more expensive hardwoods like cherry.

Key Takeaways

  • Alder is a soft, fine-grained hardwood from the Pacific Northwest that has become extremely popular for cabinetry.
  • Its even texture and warm tone make it an excellent canvas for staining, and it readily accepts finishes that mimic more expensive hardwoods like cherry.
  • Stain and lacquer for cabinets; gel stain for controlled color; water-based poly for light color; oil-based poly for warmth; shellac as sealer.
  • Straight, fine, uniform grain.
  • Diffuse-porous with small pores.

Wood Characteristics

Straight, fine, uniform grain. Diffuse-porous with small pores. 590 Janka, soft. Light tan to reddish-brown, oxidizing to warmer tone with age. Very low tannin.

Recommended Finishes

Stain and lacquer for cabinets; gel stain for controlled color; water-based poly for light color; oil-based poly for warmth; shellac as sealer.

Preparation Steps

Sand through 120, 150, 180 grit. Alder sands very easily. Use pre-stain conditioner before staining to prevent blotching. Alder can blotch though less severely than maple or pine.

Application Steps

1. Apply conditioner. 2. Apply stain in desired color (cherry and walnut tones are popular). 3. Wipe excess evenly. 4. Dry 24 hours. 5. Apply topcoat in thin coats. 6. Sand 320 between coats. 7. Apply 2-3 coats.

Maintenance Schedule

Lacquer cabinets: 10-15 years before refinishing. Poly: recoat every 5-8 years. Oil: refresh every 6-12 months. Alder is soft and shows wear on high-use surfaces.

Common Mistakes

Staining without conditioner causing blotching; expecting alder's softness to withstand heavy use; not sanding evenly leaving visible marks; using alder for high-wear surfaces like floors.

Interior vs Exterior

Interior: Excellent for cabinetry, furniture, and trim. Stains beautifully to mimic cherry or walnut at lower cost. Exterior: Alder has very poor outdoor durability. Do not use for exterior applications.
