What’s the Difference Between Polyurethane and Lacquer?

Polyurethane and Lacquer are popular choices for finishing wood furniture. While both provide a protective coating, they have significant differences in their application, appearance, durability, and maintenance. In this article, we’ll explore the differences between polyurethane and lacquer to help you choose the best finish for your woodworking project.

Understanding Polyurethane  and Lacquer

What is Polyurethane?

Polyurethane is a type of synthetic resin that is commonly used as a finish for wood furniture. It is a clear or tinted liquid that dries into a hard, durable coating. Polyurethane is a popular choice for high traffic areas because it resists scratches, heat, and water.

Types of Polyurethane

There are two types of polyurethane: oil-based and water-based. Oil-based polyurethane provides a warm, amber tone that enhances the natural beauty of the wood. It takes longer to dry and has a strong odor, but it provides a more durable finish. Water-based polyurethane dries faster, has a clear finish, and emits less odor. It is easier to clean up with soap and water, but it is less durable than oil-based polyurethane.

What is Lacquer?

Lacquer is a clear or colored coating made from nitrocellulose or acrylic resins. It dries quickly and forms a hard, glossy finish that enhances the wood’s natural beauty. Lacquer is popular for use on furniture, musical instruments, and automobiles.

Types of Lacquer

There are two types of lacquer: nitrocellulose and acrylic. Nitrocellulose lacquer is a traditional finish that dries quickly and has a hard, durable finish. It provides a warm, amber tone that enhances the natural beauty of the wood. Acrylic lacquer is a modern finish that dries quickly, has a clear finish, and is more durable than nitrocellulose lacquer. It is also easier to clean up with soap and water.

Differences between Polyurethane and Lacquer

Application

Polyurethane and lacquer have different application methods. Polyurethane is applied with a brush, roller, or sprayer, and it requires multiple coats to achieve the desired finish. Each coat must be sanded before applying the next coat. Lacquer is also applied with a brush, roller, or sprayer, but it dries faster and requires fewer coats than polyurethane.

Appearance

Polyurethane and lacquer have different appearances. Polyurethane has a clear or amber tone that enhances the natural beauty of the wood. It provides a glossy or satin finish, depending on the sheen level. Lacquer has a hard, glossy finish that also enhances the natural beauty of the wood. It provides a high-gloss finish that can be tinted with colors or pigments.

Durability

Polyurethane and lacquer also have different levels of durability. Polyurethane is highly durable and resistant to scratches, heat, and water. It is a popular choice for high-traffic areas and outdoor furniture. Lacquer is also durable, but it is more prone to scratches and damage from heat and water. It is best used on indoor furniture that does not get as much wear and tear.

Maintenance

Polyurethane and lacquer require different levels of maintenance. Polyurethane is easy to clean with soap and water, and it does not require much maintenance once it is applied. Lacquer, on the other hand, requires more maintenance. It can be easily scratched, so it needs to be cleaned with a soft cloth and maintained with regular applications of wax or polish.

Polyurethane and Lacquer where is Best for Your Project?

Choosing the right finish for your project depends on several factors, including the type of wood, the desired appearance, and the level of durability required. Polyurethane is a good choice for high-traffic areas and outdoor furniture because of its durability and resistance to scratches, heat, and water. Lacquer is a good choice for indoor furniture that does not get as much wear and tear because of its high-gloss finish and quick drying time.
