Polycrylic and polyurethane are two common wood sealers that are often used by experienced woodworkers to finish their projects. However, the similar name and purpose can cause some confusion, especially for new DIYers.

In general, polycrylic can be best understood as a light-duty sealant that dries quickly with a clear or slightly milky hue. It's low in flammability and volatile organic compounds (VOCs).

Polyurethane is better for high traffic areas, though it does take longer to dry. Oil-based polyurethane is a flammable product with a high level of VOCs. Water-based polyurethane still has a higher level of VOCs than polycrylic.

Use this guide to find out more about the differences and similarities of polycrylic vs. polyurethane, so you can feel confident knowing the benefits and drawbacks of each when you start your next woodworking project.

Polycrylic vs. Polyurethane: Major Differences

While the main purpose of polycrylic and polyurethane is essentially the same, there are some significant differences that set these products apart. Polycrylic is a water-based product that tends to dry quickly with a clear or slight milky white hue, and will last about three years before needing to be retouched. Polyurethane can be either water-based or oil-based. It doesn't dry as quickly as polycrylic, but polyurethane tends to be easier to apply and has a higher resistance to water, heat, and physical damage.

Typically, polycrylic costs about $20 to $30 per quart and it's relatively safe to use because it is non-flammable and has a low level of VOCs. Water-based polyurethane can be cleaned up with soap and warm water, like polycrylic, but oil-based polyurethane needs to be cleaned with mineral spirits or paint thinner. Additionally, polyurethane tends to cost more, at about $20 to $50 per quart. It dries with a clear or slight yellow hue, and generally lasts three years before needing to be refinished.

When you are looking for a polycrylic product to seal your woodworking project, you can find satin, gloss, high gloss, and matte finishes. Select the best option based on how you want your finished project to look. Keep in mind that polycrylic tends to appear milky white during application, though it is typically clear when it dries. If you apply the polycrylic in thick coats, it may retain a slight milky white hue.


Polyurethane users can find both water-based and oil-based versions in satin, gloss, and high gloss finishes. The appearance of the polyurethane sealant depends on whether it is water-based or oil-based. A water-based polyurethane product will generally dry completely clear, but an oil-based product typically retains a slight, yellow hue.

Best for Appearance: Tie

There isn't a significant difference between these products. Both can dry clear or have slight tinges of residual color, though polycrylic has a slight edge over polyurethane due to a higher number of finish options.

Water and Heat Resistance


A sealant is designed to protect the object it is applied to from moisture, heat, and physical damage. Polycrylic performs this function, keeping wooden furniture safe from spills and mild burns, though it is not suitable for outdoor application. This is because polycrylic only has a mild to moderate resistance against water and heat. Rain, snow, sleet, hail, and long periods spent in direct sunlight would inevitably damage the wood.


For a more water and heat resistant option, use polyurethane to protect your woodworking projects and fine furniture. Oil-based polyurethane has a high level of resistance against moisture, UV radiation, and heat, ensuring that the wood remains protected. However, it should be mentioned that water-based polyurethane does not have the same resistances as oil-based polyurethane, and only polyurethanes, of either type, labeled specifically for outdoor protection should be used for exterior projects or on items that will spend much of their time outdoors.

Best for Water and Heat Resistance: Polyurethane

A primary reason to use a sealant to finish your woodworking project is to keep the wood safe. In this regard, oil-based polyurethane is the best choice. It has a high level of resistance against water, heat, and UV radiation, making it a great option for sealing high-traffic floors or furniture that sees heavy use.

Care and Cleaning


After applying polycrylic to a piece of wooden furniture, you may be left with a bit of a mess to clean up. Fortunately, polycrylic can be cleaned with nothing more than soap, warm water, and little physical effort on your part. Once the polycrylic layer on the furniture or woodworking project is dry and fully cured, it can be washed with a damp cloth, without worrying about water damage.


When your woodworking project has been finished with a water-based polyurethane coat, you can clean up any drip or spills with warm water and soap. However, oil-based polyurethane needs to be cleaned with mineral spirits or paint thinner. After allowing the polyurethane to dry, you can keep the woodworking project clean by wiping it down or scrubbing it with a damp cloth to remove dust, dirt, or grime.

Best for Care and Cleaning: Polycrylic

All you need to clean up after using polycrylic is soap and warm water. You can also clean water-based polyurethane with soap and warm water, but the drawback to using oil-based polyurethane is that you need to rely on mineral spirits or even paint thinner to clean up any drips or spills.

Durability and Maintenance


Protecting the wood against water and heat is only part of a sealant's job. This finish is also supposed to keep the object safe from physical damage, like scratches or dents. Polycrylic is a durable choice that can provide moderate protection to wooden furniture or floors. It acts as a thin barrier, preventing direct damage to the wood, though polycrylic does not hold up as well as polyurethane.


If you are planning on applying a protective finish to a high-traffic area of wooden floor or to a commonly used piece of furniture, like a chair, then polyurethane is the best option. It is a high durability product that can protect the wood from scratches, dents, chips, nicks, and the usual wear-and-tear to which high-traffic locations and objects are often subjected. Specifically, oil-based polyurethane is the most durable choice to keep your wooden furniture, floors, or woodworking projects safe.

Best for Durability and Maintenance: Polyurethane

Oil-based polyurethane is made to hold up against physical abrasion, scratches, dents, chips, nicks, and more. This durable finish protects the underlying wood to keep the object in good condition, even in high-traffic areas. However, water-based polyurethane is not as durable as the oil-based product, so it's recommended to invest in an oil-based polyurethane to increase the durability of your floors, furniture, or any other wooden objects.



One of the drawbacks of polycrylic is that it has a loose, runny consistency that can be difficult to apply to vertical surfaces. It dries very quickly, making it a great choice for small woodworking projects. However, due to the speed at which the product dries, it's hard to get smooth, even coats on larger woodworking projects. Polycrylic should be applied with a brush or sprayer in about three thin coats.


Make sure you are working in a well-ventilated space and that you are wearing a respirator that is designed to filter out VOCs. Polyurethane is generally easier to apply than polycrylic because it has a thicker consistency. Use a brush or sprayer to apply polyurethane in about three coats. It's recommended to lightly sand each coat after it has had time to dry to give the next coat better surface adhesion.

Polyurethane is a better option for finishing large woodworking projects. Just be careful not to shake, swish, or otherwise the churn the polyurethane, as this can create bubbles that will stick to the surface of the wood and need to be sanded before a second or third coat can be applied.

Best for Installation: Tie

Generally, polyurethane tends to be easier to apply to large projects and to vertical surfaces because the product is thicker, so it doesn't run during application. However, polycrylic is a non-flammable, low VOC option, that is easier to use indoors than polyurethane. It also dries at a noticeably faster rate, making it a good choice for small woodworking projects.



If the cost of the finish is a deciding factor, then polycrylic is the way to go. On average, it costs about $20 to $30 per quart. Though, it's necessary to point out that this is about the same price as a water-based polyurethane product.


When it comes to the price, polycrylic and water-based polyurethane are about the same. Oil-based polyurethane is slightly higher in cost, ranging from about $20 to upwards of $50 per quart.

Best for Cost: Polycrylic

Polycrylic has a slight advantage over polyurethane due to the higher cost of oil-based polyurethane products. However, you can get a water-based polyurethane product for about the same price as a polycrylic product.



The lifespan of a sealant refers to the length of time between the initial application and when it next needs to be retouched or refinished. On average, polycrylic will last about three years before it should be refinished to ensure the continued safety of the floor, furniture, or other wooden object.


Polyurethane has essentially the same lifespan as polycrylic. You should plan to refinish or retouch the polyurethane sealant on a woodworking project, piece of furniture, or wooden floor about once every three years.

Best for Lifespan: Tie

In this category, both polycrylic and polyurethane are completely equal. After applying either of these finishes, it's a good idea to reapply or retouch the finish about once every three years.

Environmental Impact


The environment and anyone nearby while you are working will thank you for using polycrylic over polyurethane. Polycrylic is a non-flammable sealant that doesn't have a strong chemical odor. It also has lower VOCs, though it's still recommended to work in a well-ventilated space with an appropriate mask.


Polyurethane is not an environmentally friendly option. It's a combustible substance that gives off powerful chemical odors, and it is high in volatile organic chemicals (VOCs). Water-based polyurethane isn't as bad as oil-based polyurethane, but the VOC count is still relatively high. Always make sure to work in a well-ventilated area when you are applying polyurethane.

Best for Environmental Impact: Polycrylic

Not only is polycrylic a non-flammable substance, but it also has lower VOCs and does not produce the same chemical odor as polyurethane. Water-based polyurethane is better than oil-based polyurethane, but it still isn't as environmentally friendly as polycrylic.

The Verdict

After weighing the benefits and drawbacks of polycrylic vs. polyurethane it starts to become clear where and when to use each product. Polycrylic is a great finish option for small woodworking projects that will remain indoors and receive relatively limited interaction, like cabinets, trim, or seldom-used wooden furniture.

Water-based polyurethane should mostly be used on indoor furniture, wood floors, and other wooden objects that experience moderate use. It has a higher durability than polycrylic, allowing it to hold up better than polycrylic. Oil-based polyurethane is the best option for finishing high-traffic wood flooring or commonly used indoor furniture. Use only polyurethane products labeled for outdoor use on exterior projects, regardless of whether they're water or oil based.
