Acrylic paint is a popular choice for many DIY projects because it is affordable and easy to use. However, you may be wondering if you can use polyurethane over acrylic paint. Yes, you can! But a few things you need to know before you get started.
Polyurethane is a clear coating that can be applied over paint to protect it from scratches, stains, and fading. It is available in both water-based and oil-based formulas. Water-based polyurethane is easier to apply and cleanup, but it will not provide as much protection as oil-based polyurethane.
Before you apply polyurethane, make sure the paint is completely dry and free of any dust or debris. Apply a thin, even coat of polyurethane with a brush or roller, and allow it to dry completely.
How to apply Polyurethane Over Acrylic Paint? A step-by-step guide
If you’re looking for a durable finish for your painted surface, you may want to consider applying a layer of polyurethane over the top. Polyurethane is a clear, synthetic resin that can be applied as a protective coating to almost any surface. It dries to a hard, glossy finish and will help to protect your paint from scratches, scuffs, and other damage.
Applying polyurethane clear coat over acrylic paint is a fairly simple process. Here’s a step-by-step guide to help you get the job done:
Step 1: Wash the painted surface
You should always start by washing the painted surface to which you will apply the polyurethane. This will ensure that the surface is clean and free of any dirt or debris that could potentially cause problems later on. Use a mild soap and water solution to do this.
Step 2: Sand the painted surface
Once the surface is clean, you will need to sand it down in order to create a smooth surface for the polyurethane to adhere to. It would be best if you used fine-grit sandpaper for this purpose. Sanding will also help to remove any glossy finish that might be present on the paint.
Step 3: Apply the polyurethane
You can finally apply the polyurethane. Use a brush or roller to apply it evenly to the surface. Be sure to work in small sections so that the polyurethane does not dry before you have a chance to spread it out.
Step 4: Let the polyurethane dry
After you have applied the polyurethane, you will need to let it dry. This usually takes around 24 hours.
Step 5: scuff before the next coat
Once the first coat of polyurethane has dried, you must scuff the surface with fine-grit sandpaper lightly. This will help to create a smooth surface for the second coat of polyurethane to adhere to.
Step 6: Apply the second coat of polyurethane
After you have scuffed the surface, you can then apply the second coat of polyurethane.
Step 7: Let the second coat of polyurethane dry
You will need to let the second coat of polyurethane dry for around 12 hours.
Step 8: Apply a third coat of polyurethane (optional)
If you feel that the first two coats of polyurethane are not enough, you can apply a third coat. Be sure to follow the same steps as you did for the first two coats.
And that’s it! You should now have a beautifully protected paint finish that will last for years to come.
What do you need to know about using Water Based Polyurethane over acrylic paint?
If you’re looking for a top-quality paint job that will last for years, you can’t go wrong with water-based polyurethane over acrylic paint. While it’s more expensive than other types of paint, polyurethane’s durability and long-lasting nature make it worth the investment. Here’s what you need to know about using this type of paint.
Water-based polyurethane is incredibly tough and durable, making it ideal for high-traffic areas or surfaces that are subject to wear and tear. It also has a beautiful glossy finish that really brings out the colors in your paint job. Acrylic paint is less durable than polyurethane, but it’s much cheaper and easier to work with.
For this reason, many people choose to use acrylic paint as a base coat before applying a top coat of polyurethane. Applying water-based polyurethane is pretty straightforward – just ensure you follow the can’s instructions carefully. You’ll need to apply several thin coats, allowing each one to dry completely before moving on to the next.
The key is to take your time and be patient – rushing through the process will only result in an inferior finished product. Once your final coat of water-based polyurethane is dry, enjoy your beautiful new paint job knowing that it’s built to last!
Can You Put Oil-Based Polyurethane Over Acrylic Paint?
It is often thought that oil-based polyurethane and acrylic paint cannot be used together, but this is not the case. You can use oil-based polyurethane over acrylic paint as long as you follow a few simple steps. Before applying the polyurethane, ensure that the paint is completely dry and free of dust or debris.
Once the surface is prepped, you can begin applying the polyurethane. Start by applying a thin layer and then build up to a thicker layer if needed. Be sure to evenly distribute the product over the surface of the paint.
After applying the polyurethane, allow it to dry for at least 24 hours before using or touching the surface. When it has fully cured, you will have a durable and long-lasting finish that will protect your painted surfaces from wear and tear.
What Kind of Clear Coat you should Use Over Acrylic Paint?
There are a few different types of clear coat that can be used over acrylic paint, each with its own advantages and disadvantages. The most common type of clear coat is polyurethane, which is available in both water-based and oil-based formulas. Water-based polyurethane has less odor and dries more quickly than oil-based polyurethane, but it can raise the grain of the wood and may not be as durable.
Oil-based polyurethane takes longer to dry but produces a harder, more durable finish. Another option is lacquer, which dries very quickly but can be difficult to apply evenly.
Can you Use Polycrylic Over Acrylic Paint?
Polycrylic is a clear acrylic sealer that can be used over water-based and oil-based paints. It dries quickly and provides a durable, protective finish. It can be applied with a brush, roller, or sprayer.
It is an ideal sealer for painted surfaces because it does not turn yellow over time and resists scratches and stains. It can be used on various surfaces, including wood, metal, and glass.
There are a few things to remember when using polycrylic over acrylic paint.
- Make sure the paint is completely dry before applying it. Otherwise, the two products may not adhere properly.
- Apply the polycrylic in thin coats. Too much use can cause the paint to crack or peel.
- Be sure to follow the manufacturer’s instructions for both the paint and the polycrylic. Each product may have different application and drying times.
Following these simple tips, you can use polycrylic to protect your acrylic paint and extend its life.

Conclusion
You can use both oil-based and water based polyurethane over acrylic paint as long as you take the necessary precautions. Make sure you use a clear coat that is compatible with the paint you are using and always test a small area first to ensure that you are happy with the results.
Always wait until the paint is completely dry before applying any topcoat, and never apply polyurethane over wet paint. After applying the first coat of polyurethane, let it dry for 24 hours before applying the second coat. It would be best if you scruffed up in between coats with 220-grit sandpaper.
Now you know all there is to know about using polyurethane clear coat over acrylic paint – so go forth and create something beautiful!
