Buying Guide
What to consider when choosing wood molding putty:
- Project type: Outdoor vs. indoor, small cosmetic fixes vs. structural repairs.

- Setting and cure time: Quick fixes for urgency vs. longer cure for durability.
- Bond strength and shrinkage: Low shrinkage and high adhesion for trim and molding.
- Material compatibility: Epoxy putties for metal or ceramic edges; latex fillers for wood only.
Practical selection tips:
- Choose water-resistant options for exterior moldings or damp environments.
- For furniture and trim, prioritize sandability and stainability to blend with surrounding wood.
- Smaller repairs benefit from fast-set KwikWood or similar putties; larger projects may use epoxy putties for strength.
