Introduction
Acrylic paintings on canvas are a popular choice for artists because of their versatility, durability, and affordability. However, without proper sealing, acrylic paintings can be vulnerable to damage from moisture, dust, and UV light. In this article, we’ll guide you through the process of sealing acrylic paintings on canvas to ensure they last for years to come.
Choosing the Right Sealer
Before you begin sealing your acrylic painting, it’s important to choose the right sealer. There are two main types of sealers: spray sealers and brush-on sealers. Spray sealers are convenient and easy to use, but may not provide as even of a coating as brush-on sealers. Brush-on sealers require more time and effort, but can provide a more consistent and protective finish.
Types of Spray Sealers
There are two main types of spray sealers: matte and gloss. Matte sealers provide a flat, non-reflective finish, while gloss sealers provide a shiny, reflective finish. Choose the type of sealer that best suits the look and feel of your painting.
Types of Brush-On Sealers
Brush-on sealers come in a variety of finishes, including matte, satin, and gloss. Matte finishes provide a flat, non-reflective finish, while satin and gloss finishes provide varying levels of shine. Choose the finish that best complements your painting.
Preparing Your Painting for Sealing
Before you begin sealing your painting, you’ll need to make sure it’s clean and free of any dust, debris, or oils. Use a soft, lint-free cloth to gently wipe down the surface of your painting. If there are any areas of your painting that have become dirty or stained, use a damp cloth to gently clean them.
Applying the Sealer
If you’re using a spray sealer, hold the can about 6-8 inches away from your painting and spray in a sweeping motion, making sure to cover the entire surface of the painting. For brush-on sealers, use a soft-bristled brush to apply a thin, even coat of sealer over the entire surface of the painting. Be sure to follow the manufacturer’s instructions for drying time and number of coats.
Drying and Curing
After applying the sealer, allow your painting to dry completely before handling or framing. Drying times will vary depending on the type of sealer you use and the humidity levels in your environment. Once the sealer is dry, it’s important to allow your painting to cure for at least 24-48 hours before handling or framing.
Caring for Your Sealed Painting
Once your painting is sealed, it’s important to take proper care of it to ensure it lasts for years to come. Avoid exposing your painting to direct sunlight or extreme temperatures, as this can cause fading or cracking. If your painting becomes dirty or dusty, gently wipe it down with a soft, lint-free cloth.
Conclusion
Sealing your acrylic painting on canvas is an essential step in ensuring its longevity and protection from the elements. By choosing the right sealer, preparing your painting properly, and applying the sealer carefully, you can ensure that your painting will last for years to come. Remember to take proper care of your painting after sealing it to ensure it stays in pristine condition.
