Preparation Steps

Sand through 120, 150, 180, 220 grit. Fill open pores with paste grain filler tinted to match. Apply across grain, wipe when hazy. Sand flush with 320 when dry. No conditioner needed.

Application Steps

1. Apply tinted grain filler, wipe clean when hazy. 2. Dry 24 hours, sand 320 grit. 3. Washcoat of shellac. 4. Sand 400 grit. 5. Stain if desired. 6. Apply 3-4 thin topcoats. 7. Sand 400 between coats. 8. Rub out final coat with 0000 steel wool and paste wax.

Maintenance Schedule

Shellac/lacquer: refresh every 5-10 years. Marine varnish: recoat annually. Oil: reapply every 6-12 months. French polish: maintain with padding as needed.

Common Mistakes

Skipping grain filler leaves visible pores; mahogany darkens significantly over time; cold grain filler doesn't pack fully; staining too dark when wood will naturally deepen.

Interior vs Exterior

Interior: Premier furniture and trim wood. Shellac or lacquer ideal. Grain filler creates glass-smooth surface. Exterior: Moderate decay resistance. Marine spar varnish for boats. Exterior doors benefit from spar urethane with UV inhibitors.
