What are the best adhesives for repairing fractures in aged teak figurative sculptures?

Repairing fractures in aged teak figurative sculptures requires adhesives that offer strong bonding, durability, and compatibility with the wood’s natural oils. Here are the top choices:

1. Epoxy Resin: Ideal for structural repairs, epoxy provides a strong, gap-filling bond resistant to moisture and aging. Opt for a slow-curing formula for better penetration.

2. PVA Wood Glue: A cost-effective option for minor cracks, PVA glues like Titebond III are waterproof and flexible, suitable for non-load-bearing repairs.

3. Cyanoacrylate (Super Glue): Best for small, precise fixes, especially in delicate areas. Use thin viscosity for tight cracks and accelerators for faster curing.

4. Polyurethane Glue: Expands to fill gaps and adheres well to oily teak. Requires clamping and moisture to cure fully.

5. Hide Glue: Traditional and reversible, hide glue is ideal for conservation-grade repairs but lacks water resistance.

For best results, clean the fracture surfaces, apply adhesive evenly, and clamp until fully cured. Test adhesives on scrap teak to ensure color and texture compatibility.
