Why won't finish stick to cocobolo?

Extremely high natural oil content prevents most finishes from bonding. Wipe with acetone immediately before applying shellac or CA glue finish.

Is cocobolo an allergen?

Yes, cocobolo is one of the strongest wood allergens. Wear gloves and a respirator. Sensitization is cumulative and permanent.

Can cocobolo be left unfinished?

Yes. Its natural oils provide excellent protection. Hand oils from handling maintain the luster. Many knife handles and pens are left unfinished.

Wipe-on polyurethane after solvent degreasing; CA (cyanoacrylate) glue finish for turned objects; shellac (the one finish that bonds well to oily woods); friction polish for turnings.
Straight to interlocked grain with fine texture.

Wood Characteristics

Straight to interlocked grain with fine texture. Diffuse-porous with very fine pores. 2960 Janka, extremely hard. Orange, red, purple, and brown with dramatic color variation. Extremely high natural oil content. Known allergen.

Recommended Finishes

Wipe-on polyurethane after solvent degreasing; CA (cyanoacrylate) glue finish for turned objects; shellac (the one finish that bonds well to oily woods); friction polish for turnings.

Preparation Steps

Sand through 150, 220, 320, 400+ grit. Cocobolo polishes to a beautiful sheen from sanding alone. CRITICAL: wipe thoroughly with acetone or naphtha immediately before finishing to remove surface oils. Wear gloves, cocobolo is a strong sensitizer.

Application Steps

1. Sand to 400+ grit for high sheen. 2. Wipe thoroughly with acetone, let dry 5 min. 3. Apply finish immediately before oils resurface. 4. For shellac: thin coats by hand or pad. 5. For CA finish on turnings: apply with paper towel on spinning lathe. 6. Multiple thin coats. 7. Buff to high gloss.

Maintenance Schedule

Shellac: refresh every 3-5 years. CA finish: extremely durable, rarely needs maintenance. Oil: cocobolo's own oils provide natural protection. Many pieces are left unfinished to be maintained by hand oils.

Common Mistakes

Not degreasing before finishing causing complete adhesion failure; not wearing gloves (strong allergen); trying to use polyurethane without proper surface prep; using water-based finishes that won't bond to oily surface.

Interior vs Exterior

Interior: Exceptional for handles, pens, jewelry boxes, guitar backs, and small turned objects. Its natural oils make it very durable unfinished for handled items. Exterior: Not used outdoors due to expense and limited sizes.
