When you’re new to woodworking, choosing the right finish can be time-consuming and costly. Deciding what gets the upper hand in lacquer vs poly is even more complicated.

Given their similarities in look and feel, many people erroneously refer to them as the same thing. However, there are some significant differences between them, making each suitable for diverse applications.

So, to prevent further confusion, we are going to clear the air once and for all.

Let’s dive right in;

What is Lacquer?

Lacquer has been a fan-favorite of woodworkers for centuries. Initially derived 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, it dries hard and is very durable. However, to get that finish, you require a fair bit of skill. The best way to apply lacquer is with a high-volume, low-pressure (HVLP) sprayer.

There are four main types of lacquer, which we will discuss in detail further down.

Lacquer is made by combining different solvents and resins. Depending on the combination, one type of lacquer could be drastically different. While ancient lacquers were eco-friendly, modern ones include more chemicals and emit a high amount of (VOCs).

However, manufacturers are increasingly making the less toxic, water-based lacquers, although there is some debate about whether they should be classified as true lacquers.

What is Polyurethane?

Does Polyurethane Go Bad

Polyurethane is a durable, water-resistant finish that dries very hard. It can be used on a wide range of wood furniture but mainly on floors, tables, fences, and other surfaces that need protection from water and scratches.

Given how thick polyurethane can be, it is rarely used for high-end furniture.

The two main types of polyurethane are:

1. Oil-based polyurethane

It’s long-lasting but takes more time to dry. Because it’s slow drying, expert woodworkers generally prefer lacquer or water-based polyurethane over oil-based polyurethane.

However, water-based poly is less durable than oil-based ones. Even better, it’s heat resistant, so it doesn’t burn or blister. Oil-based polyurethane comes in gloss, semi-gloss and satin sheens, with full gloss being the most durable.

2. Water-based polyurethane

Water-based polyurethane is a type of polyurethane paint that uses water as the main carrier. In addition to promoting a safe environment for painters, it also has many benefits in terms of reducing waste and producing high-quality results on surfaces such as wood, metal or plastic.

It dries quickly, leaves no odors and is easy to clean up. Since it cannot withstand high temperatures, it is ideal for interior use only.

While oil and water-based polyurethane do the same thing, each one has its unique advantages and disadvantages. For example, oil-based polyurethane gives a warm glow to wood, and it yellows over time. On the other hand, water-based poly dries very clear and remains clear.

Both types of polyurethane can be used to protect wooden surfaces for over a decade when applied and maintained correctly.

Lacquer vs polyurethane

Polyurethane protects the wood by forming a plastic-like coating, while lacquer is a water-based product. Polyurethane is more durable and less likely to chip or flake than lacquer. It also has a higher sheen and can be used on both interior and exterior wood surfaces. Lacquer is more affordable, but it’s also less durable and doesn’t hold up as well to wear and tear.

Lacquer Finish vs Polyurethane Pros and Cons

Lacquer Pros and Cons

Polyurethane vs Lacquer: In-Depth Feature Comparison

Maybe I’m an old-timer, but I love wooden projects. But after working for days or weeks on a project, it can be heart-breaking to watch it wilt away in a matter of weeks.

That is why choosing the right finish is critical, most especially when it is a project you were paid to execute.

This in-depth comparison of lacquer and polyurethane will help you know which one to use in almost any situation.

1. Spray lacquer vs polyurethane – Ease of Application

One of the determining factors when choosing a wood finish is how easy it is to apply. After all, it’s better to have an excellent finish with an inferior product than a terrible one with a better product.

Lacquer is light, thin, and dries quickly, so it is best applied with a high-volume, low-presser (HVLP) sprayer. This yields a smooth finish. While lacquer can also be applied with other tools, that is only recommended for much smaller jobs when hiring or buying a sprayer is impractical.

On the other hand, polyurethane is thick, so it is best to apply it with a brush. Of course, you can also apply it with an HVLP sprayer, roller, and cloth depending on the type of polyurethane, but the brush is the recommended tool.

The problem with this is you will often see brush marks and streaks. And, if you use a cheap brush, it will leave hairs all over your wood surface. Other things to watch out for are bubbles, which are very common, and dust nibs.

Another problem when applying polyurethane is the need to sand between coats. Lacquer is its own solvent, so each thin coat melts into the previous one, thus eliminating the need for sanding unless there is a problem with an underlying coat.

All of these make applying polyurethane, as a beginner, a bit challenging to use.

Verdict: Lacquer is the clear winner

2. Polyurethane or lacquer – Safety and Toxicity

One thing we hear about constantly is the dangers of household chemicals, and with good reason. Lacquer and polyurethane emit high quantities of volatile organic compounds (VOCs), making them unsafe for people with breathing difficulties.

The bulk of the danger is during the application process. When chemicals are sprayed in the air, which is the recommended application method for lacquer, they become more toxic. That is why you should always use a respirator when applying any chemicals.

The good thing about the VOCs in these products is that they are no longer dangerous when they dry.

To combat these problems, manufacturers have developed water-based lacquer and water-based polyurethane. Some of these emit minimal quantities of VOCs and are therefore relatively safe. Besides these

Given that water-based polyurethane is more commonly used, the VOCs from lacquer is a more pressing threat.

Besides the invisible threat, there is the issue of flammability.

Lacquer is highly flammable. Therefore, you must never apply it near any open flame source, and you should only use it in a well-ventilated area.

Polyurethane is also highly flammable, but it is not as sensitive. For example, the flashpoint of Rust-Oleum woodcare lacquer/aerosol is less than 20°F, while the flashpoint of Minwax Fast-Drying polyurethane is 102.2°F, which is typical for polyurethanes.

Verdict – Polyurethane is safer and less toxic.

3. Lacquer vs polyurethane durability

The aim of a wood finish is not just to make furniture look more professional but also to protect the surface from scratches, stains, water, and everything in-between. Both lacquer and polyurethane do this excellently.

Lacquer is water-resistant, durable, and provides decent protection from scratches. However, nitrocellulose lacquer does not handle scratches properly.

Besides that, all lacquers offer little protection from heat and chemicals.

On the other hand, polyurethane is scratch and scuff-resistant, water-resistant, stain-resistant, and even heat-resistant. When it comes to outdoor polyurethane, you can also add UV-resistant to that list.

Given the many things polyurethane protects your wood from, it is not surprising that it can handle more abuse than lacquer. But, of course, it also helps that it is thicker than lacquer.

Instead of penetrating the wood, it stays on the surface, making it a lot harder to damage the project, even after several years.

However, if there is no physical or chemical damage, lacquer can last as long as or even longer than polyurethane. But then again, what are the chances of that happening?

Verdict – Polyurethane wins this round.

4. Poly vs lacquer – Drying Time

Here is one category that is overwhelmingly one-sided.

Despite how durable, versatile, and rich polyurethane is, the one thing people despise is the long drying time. It is so bad that it has almost single-handedly caused most woodworkers to switch to water-based polyurethane.

Oil-based polyurethane dries to the touch in about 4 to 6 hours but isn’t ready for the next coat in 12 to 24 hours. Given that most projects require at least 3 coats, it could take you three days just to apply water-based polyurethane alone.

Water-based polyurethane does a much better job, as it can be recoated in as little as two hours. However, as impressive as this is, it is nowhere close to lacquer.

Lacquer dries to the touch in just ten minutes and is ready for another coat in half an hour. So, you could apply 4 to five coats before you would’ve applied the second one of even the fastest drying polyurethane.

Verdict – Lacquer hands down

5. Lacquer or polyurethane – Versatility

Finally, we come to what is probably the most important factor when it comes to picking lacquer or polyurethane.

As mentioned earlier, lacquer is very common for high-end furniture or any wooden surface that won’t see much action. On the other hand, polyurethane is best for high-traffic areas such as floors, tables, countertops, and bars.

Another factor to consider is the size of the project. Given how quickly lacquer dries, it is not suitable for large projects. So, even though you could technically use lacquer on hardwood floors, the drying time makes it impractical.

Polyurethane does not have that problem. Ironically, what makes polyurethane frustrating to use is the same thing that makes it more versatile.

Verdict – Polyurethane wins again.

6. Brushing lacquer vs polyurethane – Yellowing

Oil-based finishes have a notorious habit of yellowing or ambering over time. While this can add a nice pop of color to oak and many other types of wood, not everybody is a fan, which is understandable.

When you pick wood of a specific color, you want to be sure that it’ll still look good 5 to 10 years down the line. Unfortunately, neither polyurethane nor lacquer stands the test of time.

Both of these products will yellow, though polyurethane yellows much quicker. However, water-based lacquer and water-based polyurethane will not yellow over time. They dry clear and remain transparent.

Given that water-based lacquers are not as common, and some argue they shouldn’t be referred to as lacquer, it is tempting to give polyurethane the edge.

Verdict – Tie

Different Types of Lacquer

Far removed from its eco-friendly beginnings, modern lacquers are made by dissolving synthetic polymers in lacquer thinner.

Although all lacquer finishes share some of the qualities mentioned above, significant variances give some edge over polyurethane. Learn how to put polyurethane over lacquer.

1. Nitrocellulose lacquer 

This is the most common type of lacquer and the one with the most defects. It possesses all of the unsavory characteristics above: it is not heat resistant, is highly flammable, yellows, and is highly toxic.

As a result, it is gradually being phased out of the market in favor of more efficient options.

2. Acrylic Lacquer

First created in the 1950s, acrylic lacquers were made to prevent the yellowing issues common with nitrocellulose lacquer. They are also more durable and scratch-resistant, thus boosting their advantages versus polyurethane.

These added benefits of acrylic lacquer come with the downside of being more expensive than nitrocellulose lacquer.

3. Water-Based Lacquer

Water-based lacquer is another step in the evolution process. While acrylic lacquer solved the yellowing issue, water-based lacquer tackles the toxicity problem. These emit significantly fewer VOCs and are not as flammable. 

While this is an improvement in many ways, it is not as durable as catalyzed or acrylic lacquers.

4. Catalyzed Lacquer

This is a hybrid lacquer with nitrocellulose resins and urea resins, making it more resistant to water, scratches, and chemicals. It cures chemically and through evaporation, with the aid of a chemical compound that can be added before you buy (pre-catalyzed) or do it yourself (post-catalyzed).

Despite the advancements in durability, it will still yellow over time, and the VOC count is still high.

Use Cases

Lacquer or polyurethane for table top

Lacquer is a better choice for table tops than polyurethane. Polyurethane is more prone to scratching, while lacquer is less likely to scratch. Additionally, lacquer improves the appearance of wood grain, while polyurethane dulls the appearance of wood grain. Finally, lacquer dries faster than polyurethane, so it’s less likely to cause bubbles or streaks in the finish.

Lacquer or polyurethane for kitchen cabinets

Lacquer will give you the best protection for your cabinets. It forms a hard, glossy finish that is durable and easy to clean. With just two coats of lacquer, your cabinets will be fully protected.

Polyurethane, on the other hand, will also give your cabinets good protection but it won’t be as easy to clean as lacquer. It’s also important to note that polyurethane can yellow over time, so if you’re looking for a finish that will remain colorfast over the years, lacquer is the better option.


What’s the Difference Between Lacquer and Polyurethane?

The difference between polyurethane and lacquer is that Polyurethane is a thicker and more durable sealant that takes longer to dry. Lacquer is a thin and quick-drying finish that penetrates into the wood but it can also chip and crack easily. In short, polyurethane is a curing finish, while lacquer is a drying finish.

What does lacquer do to wood?

Lacquer provides a high gloss finish to your wood furniture or floors. Lacquer also seals and protects the wood from moisture and other environmental factors that could damage the surface or cause it to warp. Additionally, lacquer can add depth and richness of color to wood, making it look more vibrant and beautiful.

Is lacquer the same as polyurethane?

No, lacquer and polyurethane are not the same. Polyurethane is more like a protective plastic that coats wood surfaces, while lacquer behaves like water as it penetrates the wood. Lacquer is thin and dries quickly but is not as durable as polyurethane and isn’t recommended for highly trafficked areas.

Is lacquer better than polyurethane?

Depends on what you’re looking for in a finish. Lacquer is a classic choice for furniture and cabinets, and it has a beautiful, glossy sheen. It’s also quite durable and easy to clean. Polyurethane offers excellent protection against scratches and wears and is best used on floors as they get lots of traffic.

What is lacquer used for?

Lacquer is a type of finishing agent that is often used on high-end furniture. It gives the furniture a glossy and smooth finish, making it look more expensive and luxurious. Lacquer is also very durable, so it can help protect your furniture from scratches and other damage. If you’re looking to add a bit of extra luxury to your home, choosing pieces of furniture that are lacquered is a great way to do it.

Is lacquer oil-based?

It can be, but it doesn’t have to be. It all depends on the ingredients used in the lacquer. Some lacquers are oil-based while others are water-based. So it really depends on the specific product you’re using.

5 thoughts on “Lacquer vs Polyurethane Finish – Which is Better for You?”

  1. Hi , I am working on a chalk painted coffee table . What works well with it ? A high build lacquer spray or polyurethane spray like rust oleum?

  2. I want to preserve a horseshoe crab shell. I have seen sites that recommend lacquer spray, polyurethane spray, and modge Podge. I think that lacquer would work from what I have read but would love your thoughts.

  3. Hello! I’ve heard that polyurethane and lacquer sprays can be applied to paper in order to give it a protective coat. I’m actually looking for something that could give my paper drawings and inkjet images a plasticky feel to it. Almost like the non-adhesive side of scotch tape, for instance. Anyways, it doesnt have to feel exactly like scotch tape but simple more of a plastic like texture than what paper normally feels like! When applied to paper, would polyurethane and lacquer sprays give that plasticky feel to paper?

    Thank you very much!
