Acrylic paint is a popular medium for artists and crafters alike. It’s versatile, dries quickly, and can be used on a variety of surfaces. However, once the paint is dry, it can be prone to chipping or flaking off. That’s where spray sealers come in. In this article, we’ll explore everything you need to know about using spray to seal acrylic paint.

What is a Spray Sealer?
A spray sealer is a clear, protective coat that is applied over dry acrylic paint. It helps to protect the paint from fading, chipping, or peeling off. Spray sealers come in various finishes, including matte, satin, and gloss. They can be used on a variety of surfaces, such as canvas, paper, wood, and more.
Why Use a Spray Sealer?
There are several reasons why you should use a spray sealer on your acrylic paint projects. Firstly, it helps to protect the paint from the elements. If your painting is going to be displayed outdoors or in an area with high humidity, a spray sealer can help to prevent the paint from cracking or peeling off. Additionally, a spray sealer can help to enhance the colors in your painting and give it a finished, professional look.
How to Use a Spray Sealer
Before using a spray sealer, make sure that your acrylic paint is completely dry. If the paint is still wet, the sealer can cause it to smear or run. Once the paint is dry, shake the can of spray sealer well and spray it evenly over the surface of your painting. You may want to do a test spray on a piece of scrap paper to get a feel for the spray pattern and pressure.
Hold the can of sealer about 8-10 inches away from the surface of your painting and spray in a sweeping motion. Be sure to overlap your sprays to ensure even coverage. You may need to apply multiple coats of sealer, depending on the surface and the level of protection you require.
Types of Spray Sealers
There are several types of spray sealers available, each with their own unique properties. Some sealers are water-based, while others are solvent-based. Water-based sealers are generally more eco-friendly and easier to clean up, but they may not be as durable as solvent-based sealers. Solvent-based sealers, on the other hand, are more durable and long-lasting, but they can be more toxic and require special cleanup.
Matte vs. Glossy Finish
When choosing a spray sealer, you’ll need to decide whether you want a matte or glossy finish. Matte sealers provide a flat, non-reflective finish that can be ideal for certain types of paintings or surfaces. Glossy sealers, on the other hand, provide a shiny, reflective finish that can help to enhance the colors in your painting.
Precautions When Using Spray Sealers
When using spray sealers, it’s important to take the necessary precautions. Always use them in a well-ventilated area and wear a mask to avoid inhaling the fumes. Additionally, make sure to protect your work surface and surrounding area from overspray by covering them with newspaper or a drop cloth.
Storage and Shelf Life
Once opened, spray sealers can last anywhere from six months to a year, depending on the brand and type. To extend the shelf life of your sealer, be sure to store it in a cool, dry place, away from direct sunlight or heat sources. Make sure the can is tightly sealed after each use to prevent the sealer from drying out.
Conclusion
Spray sealers are an essential tool for anyone who works with acrylic paint. They provide a protective coating that can help to prolong the life of your artwork and enhance its appearance. When using spray sealers, be sure to follow the instructions carefully and take the necessary precautions. With the right sealer and technique, you can create beautiful, long-lasting acrylic paint projects that will stand the test of time.
