Acrylic paints are a popular medium for artists and hobbyists alike. They are versatile, easy to use, and come in a wide range of colors. However, one common issue with acrylic paints is their tendency to peel, crack, or fade over time. This is where spray sealers come in. In this article, we will explore the benefits of using a spray sealer for acrylic paint and provide you with some tips on how to choose and use one.

What is a Spray Sealer?

A spray sealer is a clear, protective coating that is applied to a surface to protect it from damage or wear. In the case of acrylic paint, a spray sealer is used to protect the paint from UV rays, moisture, and other external factors that can cause it to deteriorate over time. Spray sealers come in different finishes, such as matte, satin, or gloss.

Types of Spray Sealers

There are two main types of spray sealers: solvent-based and water-based. Solvent-based sealers are more durable and provide better protection, but they are also more toxic and require proper ventilation when used. Water-based sealers, on the other hand, are less toxic and easier to clean up, but they may not be as durable as their solvent-based counterparts.

Choosing the Right Spray Sealer

When choosing a spray sealer for acrylic paint, consider the type of project you are working on and the finish you want to achieve. If you are working on a piece that will be exposed to the elements, such as an outdoor sculpture, a solvent-based sealer may be the best choice. If you want a more environmentally friendly option, a water-based sealer may be a better fit. Additionally, consider the finish you want to achieve. A matte sealer will provide a more subtle finish, while a gloss sealer will give your project a shiny, polished look.

How to Apply a Spray Sealer

Before applying a spray sealer, make sure that your acrylic paint is fully dry. Shake the can well and hold it about 8-10 inches away from the surface you want to seal. Spray in a sweeping motion, overlapping each pass slightly. Apply two or three light coats, rather than one heavy coat, to avoid drips and ensure even coverage. Allow the sealer to dry completely before handling your project.

Benefits of Using a Spray Sealer

Using a spray sealer for acrylic paint has several benefits. First and foremost, it protects your artwork from damage and fading, allowing it to last longer. Additionally, it can provide a more professional-looking finish, enhancing the overall appearance of your project. Finally, a spray sealer can make your artwork easier to clean and maintain, saving you time and effort in the long run.

Tips for Using a Spray Sealer

Here are some tips to keep in mind when using a spray sealer for acrylic paint:

  • Always use a spray sealer in a well-ventilated area to avoid inhaling fumes.
  • Apply multiple light coats, rather than one heavy coat, to avoid drips and ensure even coverage.
  • Test the sealer on a small, inconspicuous area before applying it to your entire project, to ensure that it doesn’t cause any discoloration or other issues.
  • Store your spray sealer in a cool, dry place to prevent it from drying out or becoming clogged.


Using a spray sealer for acrylic paint is a simple and effective way to protect your artwork and achieve a professional-looking finish. By choosing the right type of sealer and following the proper application techniques, you can ensure that your artwork will last for years to come. Remember to always take proper safety precautions when using spray sealers, and test them on a small area before applying them to your entire project. Happy sealing!
