Painting a dresser is an easy way to transform a piece of furniture and make it look new. While there are many types of paint to choose from, latex paint is not recommended as it will peel and will not hold up well. A popular topcoat option is polyacrylic, a water-based polyurethane that is known for its durability and easy application. Applying polyacrylic to painted furniture can protect and enhance the beauty of your work.

Prepare the dresser surface
Preparing the dresser surface before applying a coat of polyacrylic is crucial for achieving a smooth and durable finish. Here is a step-by-step guide to help you through the process:
Firstly, assess the condition of your dresser. If the existing finish is in good shape, without any peeling or chipping, you may not need to strip or sand it. However, if it was previously finished with polyurethane, it is advisable to prime it, as polyurethane tends to yellow over time and may bleed through light-coloured paints.
If there are rough or peeling spots on your dresser, sand those areas specifically. For a shiny and smooth dresser, lightly sand the entire piece to create a uniform surface. This process should be quick and should not take more than a few minutes. You can use fine-grit sandpaper, such as 220-grit, to smooth out the finish. Remember to wipe away any dust with a damp cloth after sanding.
Next, ensure that your dresser is clean and free from dust or debris. You can use a damp cloth to give it a good wipe-down, making sure to clean all surfaces, including the corners and handles. If there is any hardware, such as handles or knobs, that you do not want to paint, remove them or tape them off as needed.
Once the dresser is clean and smooth, you can apply a coat of primer. A shellac-based primer, such as BIN Shellac-Based Primer, is recommended for its high quality and fast-drying properties. Make sure to follow the directions on the primer and allow it to dry completely before proceeding to the next step.
After priming, you may want to lightly sand the surface again to ensure an even smoother base for the polyacrylic to adhere to. This step will also help the polyacrylic adhere better. Remember to wipe away any dust with a damp cloth after sanding.
Finally, before applying the polyacrylic, ensure that the primer or the previous paint coat is completely dry and cured. The drying time can vary depending on the type of paint used, ranging from a few days to a couple of weeks. It is crucial to wait for the surface to be fully ready to ensure the best results.

Choose the right polyacrylic finish
Polyacrylic is a water-based formula that is more environmentally friendly than other options. It is easy to clean up with soap and water, and its VOC (volatile organic compound) levels are much lower, so it doesn't emit the noxious fumes of solvent-based finishes. Polyacrylic is meant to be used only on interior surfaces such as cabinets, furniture, and trim. It is not suitable for exterior applications or surfaces that are subject to a lot of wear and tear, such as floors, or that are exposed to water.
When choosing the right polyacrylic finish, consider the type of surface you are working with. Polyacrylic is generally safe to use on a wide range of surfaces, including wood, painted surfaces, and even paper or fabric-based projects. However, it is important to test a small, inconspicuous area first to ensure proper adhesion and to prevent any damage. If you are sealing something that isn't a flat surface, such as a chair, polyacrylic is also available in a spray can, making it a convenient option.
Another factor to consider is the desired finish characteristics. Polyacrylic comes in various sheen options, including gloss, semi-gloss, satin, matte, and ultra-flat. You can also mix some paint with the polyacrylic, especially if you are using a dark paint, to create a tinted finish. Keep in mind that the drying time for polyacrylic can vary depending on factors such as humidity, temperature, and the number of coats applied.
Additionally, the application method is an important consideration. Polyacrylic can be applied by brushing, rolling, or spraying. It is recommended to apply a minimum of three coats, with light sanding between coats to promote adhesion and a smoother finish. Make sure to use a nylon scrubby-type abrasive instead of steel wool to avoid rust particles in the finish.
Finally, take into account the exposure to moisture, chemicals, abrasions, and other wear and tear factors. While polyacrylic provides protection and durability, it is not rated as waterproof. Over time, it may degrade faster than an oil-based finish. Therefore, if your project is likely to be exposed to high levels of moisture or wear and tear, you may need to consider an alternative finish or additional protective measures.

Mix the polyacrylic
Before mixing the polyacrylic, ensure that the paint on the dresser is completely dry. The drying time varies depending on the type of paint used, but at least two hours of drying time is recommended before applying the polyacrylic. Four to six hours of drying time would be ideal if you want to be cautious.
When mixing the polyacrylic, it is important to follow the manufacturer's instructions. In general, it is recommended to mix the polyacrylic thoroughly, especially if it is a water-based product. One way to mix it is to use a stir stick to combine the ingredients and ensure the topcoat works properly. If you are using a dark paint, you can add a small amount of paint to the polyacrylic to tint it slightly. This will help hide any streaks that may occur when applying the topcoat by hand or with a brush.
It is important to note that the type of tools used to apply the polyacrylic can affect the final result. For example, a foam brush may be preferred over a regular brush as it can help reduce brush strokes and marks. Additionally, using a roller is not recommended as it can introduce air bubbles that will need to be sanded out.
When applying the polyacrylic, it is recommended to use thin, even coats. Three coats are suggested for maximum durability. If you desire a smoother finish, lightly sand the surface between coats. After the final coat, allow the dresser to dry for at least 24 hours to give the finish time to cure and harden.
Some additional tips to consider when working with polyacrylic include:
- If you are using a paint sprayer, there is no need to thin the polyacrylic as it is already thin.
- If you are applying polyacrylic to raw wood, you can prevent the grain from raising by wiping the surface with a damp rag before sanding and applying the finish.
- If you are using a water-based polyacrylic over acrylic paint, it is recommended to test a small area first as it can make the colour milkier.

Apply the polyacrylic
Applying polyacrylic to a painted dresser is an excellent way to protect and enhance the beauty of your furniture. Here is a detailed, step-by-step guide on how to apply polyacrylic to a painted dresser:
Prepare the Dresser:
Before applying polyacrylic, ensure that your painted dresser is completely dry and cured. The drying time can vary from a few days to a couple of weeks, depending on the type of paint used. It is crucial to let the paint dry completely to prevent the polyacrylic from cracking or rubbing off.
Select the Right Polyacrylic:
You can choose between water-based and oil-based polyacrylic finishes. Water-based polyacrylic is a popular choice for indoor projects as it dries clear and has minimal odour. Oil-based options take longer to dry but may provide a more durable finish.
Mix the Polyacrylic:
Stir the water-based polyacrylic well with a stir stick. If you used a dark paint colour, you can add a small amount of paint to the polyacrylic to tint it slightly. This step ensures a consistent finish.
Work in a well-ventilated area to minimise fumes. Using a foam sponge, apply a thin coat of the tinted polyacrylic in the direction of the wood grain. Work in small sections to avoid overworking the area, which can cause cloudiness. Let the first coat dry for about 2-3 hours.
Sand and Apply Additional Coats:
Once the first coat is dry, lightly sand the surface with fine-grit sandpaper to smooth out any imperfections. Wipe away the dust and apply a second coat of polyacrylic, repeating the same application process. Depending on the desired finish, you may apply up to three coats.
Final Curing:
After applying the final coat, let the furniture cure for at least 24 hours before using it. The polyacrylic will continue to harden over several days, so patience is essential for achieving a durable finish.
Remember, it is better to apply several thin coats than one thick coat to prevent bubbles and drips. Always test the polyacrylic on a small area first to ensure compatibility with your paint.

Allow the polyacrylic to dry and cure
Once you have applied the polyacrylic to your painted dresser, it is important to let it dry and cure properly. The drying time for polyacrylic can vary depending on factors such as humidity, temperature, and the number of coats applied. Generally, it takes about 2-4 hours for polyacrylic to dry to the touch. However, it is recommended to wait at least 24 hours for it to fully cure. During this time, the polyacrylic will harden, resulting in a durable finish that can withstand regular use and cleaning without showing signs of wear or damage.
While you wait for the polyacrylic to dry, you can wrap your plastic glove around the foam brush or sponge to prevent it from drying out. This is especially useful if you plan to apply multiple coats, as you can quickly recoat after 2 hours. If you are using a Minwax Polycrylic Protective Finish, they recommend waiting only 2 hours between coats and then sanding with very fine sandpaper (220 grit) to ensure an even finish and proper adhesion for additional coats.
It is important to note that the curing process takes time, and you should avoid placing anything on the surface for at least 24 hours. For best results, consider waiting 48 hours before using the dresser, especially if you have used a high-sheen finish as this may show water spots from glasses or cups.
Once the polyacrylic has fully cured, you can expect a hard, durable finish that will protect your painted dresser from scratches, spills, and regular wear and tear. This clear finish will not yellow over time, allowing the colour and beauty of your painted dresser to shine through.
