Key Takeaways

Garapa, sometimes called Brazilian ash, is a dense tropical hardwood prized for its light golden-blonde color that sets it apart from darker tropical species.
It offers excellent durability at a more moderate price than ipe or cumaru.
UV-protective penetrating oil with lightfast pigments; tropical hardwood oil; water-based exterior finish for maximum UV protection.
Avoid film-forming products.
Straight to slightly interlocked grain with fine to medium texture.

Wood Characteristics

Straight to slightly interlocked grain with fine to medium texture. Diffuse-porous with medium pores. 1610 Janka, very hard. Light golden-yellow to honey-blonde. Moderate tannin.

Recommended Finishes

UV-protective penetrating oil with lightfast pigments; tropical hardwood oil; water-based exterior finish for maximum UV protection. Avoid film-forming products.

Preparation Steps

Sand with 80-120 grit to open grain. More receptive than ipe or cumaru. Clean with acetone or wood cleaner. Apply finish soon after sanding.

Application Steps

1. Sand 80-120 grit. 2. Clean with acetone. 3. Apply tropical hardwood oil or UV-protective oil. 4. Penetrate 10-15 min. 5. Wipe excess thoroughly. 6. Dry 24-48 hours. 7. Second coat for optimal UV protection. 8. 48 hours before foot traffic.

Maintenance Schedule

Oil: reapply every 6-12 months. UV protection critical as garapa darkens to amber without it. Brighten before re-oiling. Unfinished remains durable but color changes.

Common Mistakes

Inadequate UV protection allows rapid darkening; standard deck stain instead of tropical products; expecting blonde color without regular maintenance; over-applying oil.

Interior vs Exterior

Interior: Attractive light-colored flooring. Use hardwax oil or water-based poly to maintain blonde tone. Exterior: Excellent for decking when lighter color desired. UV-protective oil essential to slow color change.
