Compare lacquer vs polyurethane
Do you know the difference between lacquer vs polyurethane for your furniture varnish?

Lacquer and Polyurethane are two types of finishes commonly used in woodworking and furniture-making. They both serve to protect the wood and enhance its natural beauty, but they differ in many ways:

1. Appearance: Lacquer typically gives a more glossy and smooth finish as compared to polyurethane. Polyurethane tends to be more satin or semi-gloss.

2. Durability: Polyurethane is considered to be more durable and resistant to damage than lacquer. It's more capable of resisting scratches, heat, grease, and chemicals, making it suitable for surfaces that get heavy use or exposure, such as kitchen tables or flooring. Lacquer, while not as strong, still offers a decent degree of protection.

3. Application: Lacquer dries extremely quickly and is often sprayed on. Because it dries so quickly, it can be difficult to work with, especially for novices. Polyurethane, on the other hand, takes longer to dry but can be applied with a brush or a cloth, which some find easier to work with.

4. Repair: Lacquer is easier to repair because a new coat of lacquer will meld with the existing coats, effectively healing any scratches or flaws. Polyurethane doesn’t merge with previous layers so it's more difficult to repair if damaged or scratched.

5. Environmental Impact: Traditional, solvent-based lacquers are generally more harmful for the environment and the user compared to polyurethane, due to their high levels of volatile organic compounds (VOCs). However, water-based versions of both finishes are available that are lower in VOCs.

In general, the choice between lacquer vs polyurethane will depend on the specific needs and requirements of the project, including factors like durability, appearance preferences, application method, and environmental concerns.
