What is Lacquer?

Lacquer is the most preferred choice among woodworkers for centuries. Initially obtained from the secretions of the lac bug, lacquer remains a popular finish for cabinets and high-end wood furniture, even though its formula has changed drastically. Despite being a very thin finish, this finishing dries hard and is very durable. However, in order to get the desired finish, skills of an expert are needed. The best way to apply lacquer is with a high-volume, low-pressure (HVLP) sprayer.

Lacquer is made using the combination of different solvents and resins. Based on the combination, the kinds of lacquer differ from each other.

What is Polyurethane?

Detailed Comparison of Lacquer and Polyurethane Finishes


Lacquer- Lacquer is a traditional style finishing that has been used for centuries. It is typically composed of nitrocellulose, which is dissolved in a solvent like acetone or lacquer thinner. When applied to a wood surface, the solvent evaporates, leaving behind a thin film of solidified lacquer.

Polyurethane (PU)- Polyurethane finishes, on the other hand, is a modern invention which is made combining polyurethane resins with various additives and solvents. The resulting mixture forms a protective coating when applied to wood.

Application Methods

Lacquer- Lacquer is known for its ease of application and can easily be sprayed using a spray gun or applied with a brush. The fast-drying time of lacquer allows for quick recoating, making it a favourite among professional woodworkers for its efficiency. Lacquer dries to the within a few minutes only and you can do another coat in half an hour.

Polyurethane (PU)- Polyurethane finishes can be applied using various methods, including brushing, spraying, or wiping on with a cloth. However, PU finishes tend to have a longer drying time compared to lacquer, which can be a drawback for those who require a fast turnaround.

PU takes an hour to fry and is not ready for another coat for a minimum 12-24 hours. Given that most projects require a minimum 3 coats, it might take up to three days as well to apply water-based polyurethane alone.


Lacquer: Lacquer offers good durability for indoor applications. It forms a hard and glossy finish that resists moisture, chemicals, and moderate wear. However, it can be prone to chipping and scratching, making it less suitable for high-impact areas or outdoor use.

Polyurethane (PU): Polyurethane finishes are renowned for their exceptional durability. They create a tough and resilient surface that withstands abrasion, impacts, moisture, and chemicals. This makes PU ideal for high-traffic areas and outdoor projects where longevity is a key concern.


Lacquer: Lacquer provides a high-gloss, clear finish that enhances the natural beauty of the wood. Its transparency allows the wood's grain and color to shine through, giving a classic and elegant look. Lacquer also tends to age gracefully, developing a beautiful patina over time.

Polyurethane (PU): Polyurethane finishes come in various sheen levels, from high-gloss to satin and matte. They can be customised to achieve the desired level of shine. PU finishes have a more plastic-like appearance compared to lacquer, which can make the wood appear slightly less natural. However, this is a matter of personal preference.

Environmental Considerations

Lacquer: Traditional nitrocellulose lacquers contain volatile organic compounds (VOCs), which can contribute to air pollution and pose health risks during application. However, there are low-VOC and water-based lacquer alternatives available that are more environmentally friendly.

Polyurethane (PU): PU finishes also contain VOCs, especially the solvent-based versions. However, water-based polyurethane finishes have significantly lower VOC levels, making them a greener option. Water-based PUs are also easier to clean up and emit fewer harmful fumes during application.

Repair and Maintenance

Lacquer: One of the advantages of lacquer is its ease of repair. Scratches and small damages can often be fixed by simply applying a new layer of lacquer and buffing the surface. This makes it a practical choice for furniture that may experience wear and tear.

Polyurethane (PU): Polyurethane finishes can also be repaired, but the process can be more involved. Sanding and recoating are often necessary to address scratches or damage. While PU is durable, it may require more effort to maintain its appearance over time.


Lacquer: Lacquer is generally more affordable than polyurethane, making it an attractive choice for budget-conscious woodworkers. However, the lower cost may be offset by the need for more frequent maintenance and reapplication in high-wear areas.

PU: Polyurethane finishes tend to be more expensive upfront, but their durability can result in long-term cost savings since they require less frequent recoating and maintenance.

Use Cases

Lacquer/Polyurethane for Table Top

Lacquer is an ideal choice for table tops as compared to polyurethane. Table top polyurethane is more prone to scratching, on the other hand lacquer is less likely to scratch. Moreover, lacquer helps enhance the overall appearance of wood grain, while polyurethane dulls the appearance of wood grain. Lacquer polish dries quickly as compared to polyurethane.

Lacquer/Polyurethane for Kitchen Cabinets

Lacquer improves the overall protection for your cabinets as it forms a hard, glossy finish making it more durable. By applying just two coats of lacquer, you can keep your cabinets protected.

On the other hand, Polyurethane can also keep your cabinets protected but it will not be so easy to clean as compared to lacquer. With time, polyurethane can yellow, and might make the furniture look dull. So if you look for a finishing that remains colorfast over the years, then lacquer is an ideal option.

How To Choose A Right Finish: Lacquer Vs Polyurethane 

Selecting between lacquer and polyurethane for your finishing project is based on your priorities and project requirements. Lacquer offers a high-gloss, clear finish that enhances wood's natural beauty but is less durable and susceptible to damage from moisture and chemicals. It dries quickly and is easier to repair, making it suitable for those seeking a glossy appearance with a fast turnaround.

On the other hand, polyurethane offers excellent durability and resistance to wear, moisture, and chemicals. It comes in various types and is more versatile in terms of finish customization. However, it takes longer to dry between coats and can be challenging to repair, often requiring extensive refinishing.

Based on your project's specific needs, like appearance, durability, and application time, you need to make the final selection. If you give priority to a glossy finish and quick drying, then lacquer is an ideal option. If durability and versatility are key, polyurethane is a better choice. Additionally, factor in your skill level and environmental concerns, as water-based options for both finishes are more eco-friendly and easier to work with for beginners.


In summary, the choice between lacquer and polyurethane finishes depends on your specific project requirements, preferences, and environmental considerations. Lacquer offers a classic, high-gloss look with easy application and repair but may be less durable and have higher VOC content. Polyurethane provides exceptional durability, a range of sheen options, and environmental-friendly choices but may require more effort during application and repairs.

Ultimately, the decision comes down to balancing aesthetics, durability, ease of maintenance, and environmental concerns. Whichever finish you choose, proper preparation, application, and maintenance are essential for achieving a long-lasting and attractive wood surface.
