Factors to Consider When Choosing a Sealer
Selecting the best sealer for acrylic paint involves considering several factors, including the type of artwork, the desired finish, and the environment in which the artwork will be displayed.
Type of Artwork
The type of artwork you’re sealing will influence your choice of sealer. For example, a delicate watercolor painting may require a different sealer than a heavily textured acrylic painting on canvas.
Desired Finish
Sealers are available in a range of sheens, from matte to high gloss. Consider the desired aesthetic of your artwork when selecting a sealer. A matte finish will reduce glare and provide a subtle, natural look, while a glossy finish will enhance color vibrancy and create a more dramatic effect.
Environment
The environment in which your artwork will be displayed is another important consideration. If your artwork will be exposed to high humidity or UV rays, you’ll need a sealer that offers adequate protection against these elements. The best sealer for acrylic paint in this case will be one with UV inhibitors.
Application Method
Consider your preferred application method when choosing a sealer. Liquid sealers can be applied with a brush, roller, or sponge, while spray sealers offer a convenient, even application. Choose a method that you are comfortable with and that is appropriate for the size and complexity of your artwork.
How to Apply Sealer to Acrylic Paint
Proper application is crucial to achieving the desired results with your sealer. Follow these steps for a flawless finish:
- Prepare the Surface: Ensure the acrylic paint is completely dry and free of dust, dirt, and debris.
- Choose Your Application Method: Select a brush, roller, sponge, or spray can, depending on the type of sealer and your personal preference.
- Apply the Sealer: Apply a thin, even coat of sealer, working in smooth, overlapping strokes. Avoid applying too much sealer at once, as this can lead to drips and uneven coverage.
- Allow to Dry: Allow the sealer to dry completely according to the manufacturer’s instructions. This may take several hours or even overnight.
- Apply Additional Coats (Optional): For added protection, apply a second or third coat of sealer, allowing each coat to dry completely before applying the next.

Troubleshooting Common Sealer Problems
Even with careful application, you may encounter some common problems when sealing acrylic paint. Here are some tips for troubleshooting these issues:
- Bubbles: Bubbles can occur if the sealer is applied too thickly or if the surface is not properly prepared. To prevent bubbles, apply thin, even coats of sealer and ensure the surface is clean and dry. If bubbles do occur, you can try gently popping them with a pin or needle while the sealer is still wet.
- Streaks: Streaks can occur if the sealer is not applied evenly or if the brush or roller is not properly cleaned. To prevent streaks, use a high-quality brush or roller and apply the sealer in smooth, overlapping strokes. Clean your brush or roller thoroughly after each use.
- Yellowing: Yellowing can occur if the sealer is not UV-resistant or if it is exposed to direct sunlight for extended periods. To prevent yellowing, choose a sealer that is specifically formulated to resist UV damage and avoid displaying your artwork in direct sunlight.
- Cracking: Cracking can occur if the sealer is not flexible enough for the surface it is applied to. To prevent cracking, choose a sealer that is specifically designed for acrylic paint and that is flexible enough to accommodate the expansion and contraction of the surface.
