Acrylic paint is a versatile medium, popular for its vibrant colors and quick drying time. To ensure your artwork lasts, it’s crucial to seal acrylic paint properly. Sealing protects the paint from dust, UV rays, and moisture, preserving its beauty for years. Here’s a comprehensive guide on what to put over acrylic paint to seal it effectively.

Why Seal Acrylic Paint?

Sealing acrylic paint is essential to protect your artwork from environmental damage. It enhances durability, prevents fading, and can even add a desired finish, whether matte, satin, or glossy. Sealing your acrylic paint ensures that your artwork remains vibrant and intact over time.

What Can You Use to Seal Acrylic Paint?

Several products can be used to seal acrylic paint, each offering different benefits. Here’s a look at some popular options:

1. Acrylic Varnish

Acrylic varnish is a top choice for sealing acrylic paint. It comes in various finishes, including matte, satin, and gloss, allowing you to choose the look you prefer.

• Application: Apply with a soft brush in thin, even layers.
• Benefits: Provides UV protection and enhances color vibrancy.
• Example: Liquitex Acrylic Varnish is a well-regarded option.

2. Polyurethane

Polyurethane is another effective sealant, particularly for items that require extra durability, like furniture or outdoor pieces.

• Application: Available in both spray and liquid forms; apply in thin coats.
• Benefits: Offers strong protection against scratches and water.
• Example: Minwax Polycrylic is a popular choice for clear finishes.

3. Resin

For a high-gloss, glass-like finish, consider using resin. This option is excellent for achieving a professional look.

• Application: Mix resin and hardener, then pour over the surface.
• Benefits: Provides a thick, durable coat that enhances depth and vibrancy.
• Example: ArtResin is a trusted brand for artists.

4. Spray Sealants

Spray sealants are convenient for quick applications and are available in various finishes.

• Application: Hold the can 12 inches away and spray evenly.
• Benefits: Easy to apply and ideal for large surfaces.
• Example: Krylon UV-Resistant Clear Acrylic Coating is a favorite among artists.

How to Apply Sealer Over Acrylic Paint

Applying a sealer over acrylic paint is straightforward, but following the right steps ensures the best results.

1. Clean the Surface: Ensure your painting is dry and free from dust.
2. Choose the Right Sealer: Select a sealer based on the desired finish and protection level.
3. Test First: Always test the sealer on a small area to ensure compatibility.
4. Apply Evenly: Use a soft brush or spray evenly, avoiding drips.
5. Allow to Dry: Let each coat dry completely before adding another.

Tips for Sealing Acrylic Paint

• Temperature and Humidity: Work in a well-ventilated area with moderate temperature and low humidity.
