Main Content:
Acrylic paintings are versatile and durable, but they can still be prone to dust, dirt, and even fading if not protected properly. That’s why it’s important to seal them with a protective layer. Here are the steps:
Step 1: Wait Until the Painting is Completely Dry
Before sealing your acrylic painting, make sure it is completely dry. This usually takes around 24 hours, depending on the thickness of the paint and the humidity level. If you seal it before it’s dry, the paint may smear or become damaged.
Step 2: Choose the Right Sealant
There are different sealants available, such as varnish, spray fixative, or acrylic medium. The type of sealant you choose depends on your preference and the effect you want to achieve. Varnish gives a glossy finish, while spray fixative gives a matte finish. Acrylic medium can be mixed with the paint to create a protective layer.
Step 3: Apply the Sealant
Apply the sealant in thin, even coats using a brush, roller, or spray. Make sure to apply it in a well-ventilated area and follow the manufacturer’s instructions. Let each coat dry completely before applying another one. Usually, two to three coats are enough.
Step 4: Let the Painting Dry
After applying the last coat, let the painting dry completely for at least 24 hours before touching it or framing it. This will ensure that the sealant has fully cured and the painting is ready to be displayed or stored.
Step 5: Store the Painting Properly
After sealing your acrylic painting, make sure to store it properly. Keep it away from direct sunlight, extreme temperatures, and humidity. Use acid-free materials to frame it or store it in a protective sleeve or box.
