What Are Wood Varnishes And Lacquers?
Varnish and lacquer are two common finishes used on wood products, providing a protective and glossy coating. Let’s take a closer look at each of these finishes and their characteristics.
Wood Varnishes
Varnish is a top coat or finish applied to wood projects, furniture, and porches. It is transparent, dries hard, and offers excellent protection against wear and tear. Varnish is typically made from a combination of resin, drying oil, and a thinner or solvent. The resin provides durability, while the drying oil enhances the drying process. The thinner or solvent helps the varnish to spread easily and evaporates as the varnish dries.
Wood Lacquers
Lacquer is another type of finish used on wood surfaces. It is a solvent-based product that creates a synthetic coating on the wood. Lacquer dries quickly and provides a high-gloss finish. One of the main components of lacquer is shellac, which is dissolved in alcohol to form a solution. The alcohol evaporates as the lacquer dries, leaving behind a protective layer on the wood.
Both varnish and lacquer have their own unique qualities and applications. While varnish offers exceptional durability and protection against physical damage and UV light, lacquer provides a quick-drying finish with a glossy appearance. The choice between varnish and lacquer ultimately depends on the desired look, durability requirements, and specific application of the wood product.

Chemical Effect of Varnish And Lacquer
When considering the use of varnish and lacquer on wood products, it is important to be aware of their potential chemical effects, especially when other materials are involved. The composition of varnish typically consists of a resin, drying oil, and a thinner or solvent. On the other hand, lacquer is a solvent-based product that contains shellac dissolved in alcohol.
One key consideration is the potential staining caused by chemical reactions between the finishes and other materials. For example, rubber handles or heads on tools may have a chemical effect with lacquer, causing unsightly stains on the wood. It is essential to be cautious when applying lacquer to wood products that come into contact with these types of materials.
Moreover, varnish and lacquer can also have different effects on the wood itself. Varnish provides a transparent and durable finish that offers protection against physical damage and UV light. In contrast, lacquer creates a synthetic coating on the wood and dries quickly to create a high-gloss surface. However, lacquer may be prone to discoloration and scratches over time.
Chemical Effect Summary:
- Varnish is composed of resin, drying oil, and a thinner or solvent.
- Lacquer contains shellac dissolved in alcohol.
- When using lacquer, be cautious of potential staining caused by chemical reactions with other materials.
