How To Seal Acrylic Paint on Wood

To seal acrylic paint on wood, you have several options. The most common methods include applying a polycrylic finish, varnish, Mod Podge, spray sealant, or water-based polyurethane. Each of these sealants can provide protection and enhance the durability of the acrylic paint on your wood surface.

When applying sealant, be sure to use even, smooth strokes and allow each layer to dry completely before applying additional coats.

Polycrylic Finish

A polycrylic finish is a popular choice for sealing acrylic paint on wood. It is a low odor, nonflammable, protective topcoat that can be applied over bare wood or oil or water-based paints. Polycrylic finishes like Minwax Clear offer protection and add a beautiful finish to your painted wood. They are easy to apply with a brush and dry quickly, allowing for multiple coats if needed.

Varnish

Varnish is a transparent protective coating that dries clear and hard. It can effectively seal acrylic paint on wood surfaces, providing durability and longevity to your artwork. Liquitex is a recommended varnish brand that offers options for both glossy and matte finishes. To apply varnish, ensure the painted surface is completely dry, and gently brush on long, even strokes in a horizontal direction. Wait for each coat to dry before applying additional coats.

Mod Podge

Mod Podge is a versatile decoupage medium that can be used as a glue, sealant, and varnish. It is commonly used for sealing acrylic paint on wood and is available in matte and gloss finishes. The Mod Podge Complete Kit includes both matte and gloss finishes, providing options for different aesthetic preferences. Apply Mod Podge in even layers with a foam brush, allowing each layer to dry before applying additional coats.

Spray Sealant

Spray sealants, such as Krylon Crystal Clear, provide a quick and easy way to seal acrylic paint on wood surfaces. Spray sealants offer a protective gloss coating and can cover a large area with an even coating. When using a spray sealant, shake the can thoroughly, spray evenly over the wooden surface from a distance of at least 30 centimeters, and allow it to dry completely. It is important to work in a well-ventilated area and use protective gear.

Water-Based Polyurethane

Water-based polyurethane is a popular choice for sealing acrylic paint on wood surfaces. Varathane Water-Based Ultimate Polyurethane, for example, offers a satin finish and is scratch and stain-resistant. To apply water-based polyurethane, use a thick bristle brush and apply smooth, even strokes in one direction. Allow each coat to dry for the recommended time before applying additional coats.

Apply a Polycrylic Finish

When it comes to sealing acrylic paint on wood, a polycrylic finish is a popular and efficient choice. A polycrylic finish acts as a protective topcoat that can be applied over bare wood or oil or water-based paints. Not only does it provide essential durability and protection for your painted wood, but it also adds a beautiful finish that enhances the overall appearance.

One highly recommended polycrylic finish option is Minwax Clear, which offers excellent protection while maintaining the natural beauty of the wood. With its low odor and nonflammable properties, Minwax Clear is a reliable choice for sealing acrylic paint on wood surfaces.

Applying a polycrylic finish is a straightforward process that can yield great results. You will need a brush suitable for the size of your project and ensure that the paint is completely dry before starting.

How to Apply a Polycrylic Finish

  1. Start by stirring the polycrylic finish well to ensure an even consistency.
  2. Using the brush, apply a thin and even layer of polycrylic finish to the painted wood surface. Be careful not to overload the brush, as this can lead to drips and uneven coverage.
  3. Work in long, smooth strokes, moving with the grain of the wood for a seamless application.
  4. Allow the polycrylic finish to dry completely according to the manufacturer’s instructions. This usually takes about two hours.
  5. If desired, you can lightly sand the surface with fine-grit sandpaper after the first coat has dried. This helps create a smoother finish and promotes adhesion for subsequent coats.
  6. Apply additional coats of polycrylic finish as needed, following the same application and drying process.

It is best to apply varnish in multiple thin coats rather than one thick coat. This allows each layer to dry properly and ensures a smoother, more even finish. Wait for each coat to dry completely before applying additional coats. Depending on the desired level of protection, you may need to apply two or more coats of varnish.

Using varnish to seal acrylic paint on wood surfaces offers several advantages. Firstly, it protects the paint from fading, yellowing, and damage caused by light exposure.

Apply Water-Based Polyurethane

When it comes to sealing acrylic paint on wood surfaces, water-based polyurethane is a popular and effective choice. One highly recommended option is Varathane Water-Based Ultimate Polyurethane, which offers a smooth satin finish and is known for its scratch and stain resistance.

It’s important to allow each coat of polyurethane to dry completely before applying additional coats. Refer to the manufacturer’s instructions for the recommended drying time, as it may vary depending on the specific product you’re using.

By applying multiple coats of water-based polyurethane, you can achieve a more durable and long-lasting seal. This will provide added protection to your acrylic paint on wood, guarding it against moisture, UV exposure, and everyday wear and tear.

Remember to work in a well-ventilated area when applying polyurethane and wear appropriate protective gear, such as gloves and a mask, to ensure your safety. Taking these precautions will help you create a beautiful and protected finish for your acrylic paint on wood.

Things To Consider Before Choosing a Sealant

Before selecting a sealant for your acrylic paint on wood, there are several factors to consider that will ensure you choose the right one. These include:

  1. The Desired Finish: Determine whether you prefer a glossy, matte, or satin finish for your painted wood object. Different sealants offer different finishes, so it’s important to choose one that aligns with your aesthetic preference.
  2. The Intended Location: Consider whether the painted object will be placed indoors or outdoors. Sealants designed for outdoor use typically offer better resistance to weather conditions and UV exposure. On the other hand, if the object will be kept indoors, you may have a wider range of sealants to choose from.
  3. Level of Protection Required: Evaluate the level of protection needed for your wooden surface. Some sealants provide enhanced protection against scratches, moisture, and other external factors. Assess the intended use of the painted object and select a sealant that offers the appropriate level of durability and protection.

Additionally, it is crucial to properly prepare your wood surface and ensure that the acrylic paint is completely dry before applying the sealant. This will help ensure optimal adhesion and prevent any issues with the final result.

Tip: When choosing a sealant for acrylic paint on wood, take into account the specific requirements of your project, and select a sealant that fits both your functional needs and desired aesthetic outcome.

Tips When Sealing Acrylic Paint on Wood Surfaces

When sealing acrylic paint on wood surfaces, it’s important to follow these tips to ensure a successful and long-lasting finish:

  1. Apply thin, even coats of sealant: To achieve the best results, apply a thin layer of sealant using a brush or spray. This helps to prevent drips, bubbles, and uneven coverage, ensuring a smooth and professional-looking finish.

  2. Allow each layer to dry completely: Before applying additional coats of sealant, make sure that each layer is completely dry. This ensures proper adhesion and prevents smudging or smearing of the acrylic paint.

  3. Use smooth, even brush strokes: When using a brush to apply sealant, use smooth and even strokes in the same direction. Avoid applying too much pressure or dragging the brush over the painted surface, as this can disturb the paint and create an uneven finish.

  4. Consider using spray sealants: For a more convenient and even application, consider using spray sealants. These can provide a seamless finish and are ideal for covering larger areas. Make sure to work in a well-ventilated area and use appropriate protective gear when using spray sealants.

  5. Avoid common mistakes: Be mindful of common mistakes when sealing wood surfaces, such as applying too much sealant, not allowing proper drying time between coats, or neglecting to clean and prepare the wood surface beforehand. Taking these precautions can help you avoid potential issues and ensure a successful sealing process.

By following these tips, you can achieve a professional and durable seal on your acrylic paint projects on wood surfaces.
