Wood Characteristics

Prominent ring-porous grain similar to oak, straight and coarse. 1320 Janka. Light cream to pale brown. Low tannin, much less reactive than oak.

Recommended Finishes

Oil-based poly for warm tone and durability; water-based poly for clean contemporary look; Danish oil for natural hand-rubbed finish; lacquer for furniture-grade clarity.

Preparation Steps

Sand through 80, 120, 150, 180 grit. Fill with paste grain filler for smooth finish or leave natural. No conditioner needed. Vacuum and tack cloth thoroughly.

Application Steps

1. Apply grain filler if desired, wipe excess, dry. 2. Sand flush 220 grit. 3. Apply stain if desired. 4. Dry 24 hours. 5. Apply topcoat thinly. 6. Sand 320 between coats. 7. Apply 3 coats for floors, 2-3 for furniture.

Maintenance Schedule

Poly floors: screen and recoat every 3-5 years. Furniture: recoat every 5-8 years. Oil: refresh every 6-12 months. Full refinish every 10-15 years.

Common Mistakes

Not filling grain for smooth furniture finish; sanding against grain very visible in ash; too much stain obscures attractive grain; wrong grit sequence leaves scratches.

Interior vs Exterior

Interior: Excellent for flooring, furniture, cabinetry. Bold grain provides visual interest. Exterior: Poor natural decay resistance. Thermally modified ash available for exterior.
