When it comes to painting and sealing, there are a lot of options on the market. One of the most popular is polycrylic. Homeowners and professionals use it for years to seal and protect surfaces. But does polycrylic harden?

In this blog post, we will answer that question and discuss the benefits of using this product!

Does Polycrylic Harden?

Yes, polycrylic hardens as it dries. This is why it’s important to follow the directions on the can and to apply it in thin coats. When you put it too thickly, it will take forever to dry and will get difficult to sand smooth.

Once it’s dry, polycrylic is very durable and will protect your surfaces from scratches and wear. It’s also easy to clean – wipe it down with a damp cloth.

So when you’re looking for a tough and durable finish that’s easy to apply and clean, polycrylic is a great option.

What Is Polycrylic?

Polycrylic is a type of water-based polyurethane resin. It is most commonly used as a clear coating or sealant for wood, metal, and plastic surfaces.

Polycrylic is available in both aerosolized spray form and as a liquid that can apply with a brush or roller. It dries quickly, is non-toxic, and cleans up easily with soap and water.

Polycrylic can suit both indoors and outdoors.

Polycrylic provides a durable protective finish that resists abrasion, fading, yellowing, and other damage from UV rays and chemicals.

It is also moisture-resistant, and an ideal choice for protecting surfaces in damp or humid environments.

Polycrylic can use on a variety of surfaces, including wood, metal, plastic, and laminate. Put over paint, wallpaper, and other wall coverings.

When applying polycrylic, follow the manufacturer’s instructions carefully. In general,

-Lightly sand the surface for coating and then wipe it clean with a damp cloth.

-Once the surface is prepared, you can apply the polycrylic with a brush, roller, or sprayer.

-Put several thin coats, allowing each coat to dry completely before applying the next.

-Once the final coat is dry, you can buff it to a high shine with a soft cloth.

Polycrylic is an excellent choice for protecting surfaces in both indoor and outdoor environments. It is durable, moisture-resistant, and easy to apply. With proper preparation and care, polycrylic can keep surfaces looking like new for years to come.

How Does Polycrylic Harden?

Polycrylic hardens when it is exposed to air. The chemical reaction that causes the hardening is known as polymerization. Monomers in the polycrylic react with each other to form long chains of molecules, called polymers. The polymers are what give polycrylic its solid structure.

When you apply polycrylic to a surface, the monomers in the resin begin to react with each other and the oxygen in the air. This reaction starts slowly, but it accelerates as more oxygen exposes to the polycrylic. The entire curing process can take anywhere from 24 hours to a week. It depends on the thickness of the coating and the amount of oxygen that is present.

During the curing process, the polycrylic shrinks as it hardens. This can cause some problems when you’re not careful. Apply an even coat of polycrylic and avoid putting too much at once. When you do, the excess will pool in low areas and will dry there first. As the rest of the polycrylic around it hardens, the pooled area will shrink and pull away from the edges. This can cause cracks or bubbles in your finish.

Let each coat of polycrylic dry completely before adding another. The best way to do this is to let it cure for at least 24 hours. Since you can’t wait that long, you can use a hair dryer on the low setting to speed up the process. Do not get the polycrylic too hot, or it will start to cure too quickly and will become difficult to work with.

Once the polycrylic is completely cured, it will get hard and durable. It will turn waterproof, resist stains and scratches, and last for several years as you take care of it properly. Polycrylic is an excellent choice for protecting your surfaces.

Now that you know how polycrylic hardens, you can apply it with confidence. Follow the manufacturer’s instructions for the best results. Always test in a small area first to make sure you’re happy with the results. With a little practice, you’ll put polycrylic like a pro!

How Long Does Polycrylic Take To Harden?

Polycrylic is a water-based product, so it dries quickly. However, it can take up to 24 hours for the finish to completely harden. This is why allow ample time for the finish to dry before using or handling the piece.

When applying polycrylic, work in a well-ventilated area. The fumes can get strong, so open windows and doors to let the air circulate.

When Should You Use Polycrylic?

Polycrylic is a clear finish topcoat that goes on smoothly and dries quickly to a hard and durable finish. It’s specifically formulated to resist damage from water, scratches, and stains, suitable for both indoor and outdoor use. You can use polycrylic on almost any surface including wood, metal, glass, and plastic.

One of the advantages of polycrylic is that it can apply directly over bare wood or painted surfaces without sanding or priming first. It’s also easy to clean up with soap and water.

Polycrylic dries clear in about two to four hours, depending on temperature and humidity, so plan your project accordingly.

So when should you use polycrylic? Here are a few tips:

– When you want a clear finish that will resist water damage, scratches, and stains

– When you want an easy-to-apply finish that doesn’t require sanding or priming

– When you want a finish that dries quickly

Keep in mind that polycrylic is not recommended for surfaces that are subject to high temperatures, such as stovetops or fireplace surrounds.

Now that you know when to use polycrylic, put it to good use on your next project!

Is Polycrylic As Good As Polyurethane?

A lot of people ask if polycrylic is as good as polyurethane. Yes and no. They both have their pros and cons. Polycrylic is a water-based product so it’s easier to work with and clean-up is a breeze. It dries fast and doesn’t yellow over time like polyurethane can.

However, it doesn’t provide the same level of protection as polyurethane does. Polyurethane is oil based so it takes longer to dry and can get a pain to clean up. But, it’s more durable and provides a higher level of safeguarding from scratches, scuffs, and stains.

So, which should you use? It depends on the project. When you need something to protect your surfaces but don’t mind touch-ups now and then, go with polycrylic. But, since you want maximum protection with a little more hassle, go with polyurethane.

Will Polycrylic Hold Up To Water?

Polycrylic is a water-based product, so it is not recommended for use on surfaces that will expose to water or high humidity. However, use on surfaces that may come into contact with occasional spills, such as countertops and tabletops.

Polycrylic is also a good choice for protecting painted surfaces from wear and tear.

Tips For Using Polycrylic On Wood

When using polycrylic on wood,

-Always remember to sand the surface first. This will help the polycrylic to adhere better and create a smoother finish.

-Apply a thin layer of polycrylic and allow it to dry completely before adding another coat. When putting multiple coats, sanding in between each coat is recommended.

-Clean your brushes after each use. This will avoid brush strokes in the finish.

-Since you are looking for a glossy finish, wet sanding with progressively finer grit sandpaper can create a high shine.

-Put polycrylic with a foam brush, cloth, or a lint-free rag in long and even strokes. Work in the direction of the grain to avoid streaks.

-Wear gloves and work in a well-ventilated area when using polycrylic. The fumes can get harmful when inhaled.

When you are ready to use polycrylic on your wood project, keep these tips in mind for the best results.

I will always have a special place in my heart for woodworking. I have such fond memories working on projects with my parents on the weekends in the garage growing up. We built tables, shelves, a backyard shed, 10' base for a water slide into the pool, 2 story fort playhouse with a fire pole, and so much more. This woodworking blog allows me to write helpful articles so others can enjoy woodworking as much as we have.
