Lacquer Wood Finish Advantages And Disadvantages

Lacquer Wood Finish Advantages And Disadvantages

When it comes to finishing wood, lacquer is a popular choice for its fast drying time, durability, and wide range of sheen options. However, like any other finish, it has its advantages and disadvantages.

Here are the advantages and disadvantages of lacquer wood finish:

Advantages of Lacquer Wood Finish:

• Dries Quickly: Lacquer dries very fast, usually within 15 minutes at room temperature, allowing for the application of multiple coats in a short time.
• Easy to Apply: Lacquer comes ready to use out of the can and does not require thinning. It can be easily sprayed with basic equipment.
• Durable and Tough Finish: Lacquer cures to a hard, durable finish that is comparable or better than varnish or polyurethane. It is resistant to chipping and flaking.
• Resistant to Water and Liquids: Once cured, lacquer forms an impervious seal that protects the wood from water damage.
• Clarity and Lack of Yellowing: Lacquer remains crystal clear as it ages and does not get cloudy or yellow over time like some other finishes.
• Low Maintenance: Lacquer requires very little upkeep once applied and does not need refinishing for years in most cases.

Disadvantages of Lacquer Wood Finish:

• Susceptible to Scratches/Dents: Lacquer is less scratch-resistant than some finishes, and any sharp object can scratch through the surface.
• Difficult to Repair: Fixing scratches or dents in lacquer involves extensive sanding and recoating, and the repair may be visible.
• Toxic Fumes When Spraying: The lacquer solvents emit strong fumes during application, requiring proper ventilation.
• Risk of Blushing: Excess moisture can cause a white haze called blushing, which requires sanding and reapplication.
• Requires Spraying: Lacquer is difficult to brush on, and proper spray equipment is needed to achieve good results.

Key Takeaways:

• Lacquer wood finish offers fast drying time, making it ideal for projects with tight deadlines.
• It provides a durable and long-lasting finish, protecting the wood from scratches and everyday wear-and-tear.
• There are different types of lacquer wood finishes, including nitrocellulose, acrylic, catalyzed, waterborne, and urushiol-based lacquer.
• Each type of lacquer has its own characteristics and suitability for different applications.
• While lacquer wood finish has many advantages, it is important to be aware of potential issues such as blushing, fish-eye, orange peel, and bubbles during application.
• Additionally, lacquer is flammable and can pose health risks, so proper safety precautions should always be followed.

Nitrocellulose Lacquer

Nitrocellulose lacquer has been widely used as a finish for musical instruments and metal coatings since the 1920s. It offers a smooth, high-gloss finish that enhances the natural beauty of wood. However, there are certain characteristics and drawbacks to consider when using nitrocellulose lacquer.

Characteristics of Nitrocellulose Lacquer:

• Dries to a reddish-amber tint as it ages
• Tends to yellow over time, making it unsuitable for lighter woods like maple or ash
• Can be prone to cracking or “crazing” as it ages
• Offers limited protection against liquids, chemicals, and abrasions

Drawbacks of Nitrocellulose Lacquer:

• Yellowing and cracking can affect the appearance and durability of the finish
• Less resistant to wear and tear compared to other lacquer finishes
• Not recommended for applications that require strong protection against liquids and abrasions

“Nitrocellulose lacquer is a classic choice for achieving a glossy finish on musical instruments, but it’s important to consider its limitations when selecting a finish for wood furniture or other applications.”

Despite its drawbacks, nitrocellulose lacquer remains a popular choice for achieving a classic, glossy finish on musical instruments and metal coatings. However, for applications that require stronger protection against liquids and abrasions, other lacquer finishes such as acrylic lacquer or catalyzed lacquer may be more suitable choices.

Acrylic Lacquer

When it comes to lacquer wood finishes, acrylic lacquer is a popular choice due to its unique characteristics and numerous benefits. Unlike nitrocellulose lacquer, acrylic lacquer does not yellow over time, making it an ideal option for lighter woods like maple, birch, and ash. Its water-white finish ensures a clean and bright appearance that enhances the natural beauty of the wood.

One of the key advantages of acrylic lacquer is its exceptional durability and scratch resistance. It provides a protective layer that helps to guard against daily wear and tear, ensuring that your furniture or woodworking projects stand the test of time. This durability makes it particularly suitable for high-traffic areas or items that are frequently handled.

Moreover, acrylic lacquers offer a wide range of sheen options to suit your preferences. Whether you prefer a glossy shine or a matte finish, acrylic lacquer allows you to achieve the desired look for your project. This versatility is especially valuable when it comes to customization and design choices.

Characteristics of Acrylic Lacquer

Acrylic lacquer is formulated with synthetic acrylic polymers, which provide its unique properties. These characteristics include:

• Water-white finish
• Excellent durability and scratch resistance
• Wide range of sheen options

Thanks to these qualities, acrylic lacquer has become a favored choice for professionals and DIY enthusiasts alike, offering a reliable and visually appealing finish for various woodworking projects.

Catalyzed Lacquer

When it comes to lacquer finishes, catalyzed lacquer stands out for its exceptional durability and performance. This type of lacquer contains special drying chemicals that result in a harder and more durable finish compared to traditional nitrocellulose and acrylic lacquers.

There are two main types of catalyzed lacquer: pre-catalyzed and post-catalyzed. In pre-catalyzed lacquers, the drying chemicals are added by the manufacturer, ensuring consistent and reliable results. On the other hand, post-catalyzed lacquers, often known as conversion varnishes, allow craftsmen to add the drying chemicals themselves, offering greater control over the curing process.

The advantages of catalyzed lacquer are numerous. Its increased durability makes it an excellent choice for furniture and other woodworking projects that require long-lasting protection. Additionally, catalyzed lacquers are known for their resistance to common finishing issues, such as blushing, fish-eye, and orange peel. This makes application easier and results in a high-quality finish.

It’s no wonder that catalyzed lacquers have gained popularity in recent years. Their exceptional durability, performance, and ease of application make them a top choice for professional woodworking projects. When you need a finish that can stand up to the demands of everyday use, catalyzed lacquer is a reliable and effective option.
