Conclusion
- Varnish is ideal for wooden surfaces needing both protection and a glossy finish.
- Lacquer is best for quick-drying, high-gloss applications like musical instruments.
- Shellac offers a natural, historical alternative but is less durable than modern options.
- Polyurethane is superior for high-traffic areas due to its toughness.
- Glaze works well for artistic or decorative finishes rather than pure protection.
- Sealant should be chosen when waterproofing is the primary concern over aesthetics.
