Once you've completed your acrylic painting, it's important to seal it so that the colors remain vibrant and the paint doesn't crack or peel. Sealing your painting will also protect it from dust and dirt. There are a few different ways that you can seal your painting, and the best method will depend on the type of paint that you used and the surface that you're sealing. In this blog post, we'll cover the three most common methods for sealing an acrylic painting.
3 Pro tips before you start sealing your painting:
-
Make sure your varnish or sealer is the same temperature as your acrylic painting. Best is to have both in the same room for over 24 hours.
-
Wipe your artwork with a cloth-free towel to clean it from any dust or hairs.
-
Clean your environment, or cover your painting after the sealing process, so again dust won’t stand a chance.
- Wait until the paint is 100% cured & dry, for at least over 1 á 2 weeks. This prevents the varnish from mixing with the acrylic paint particles and to have a beautiful long term effect.
Method 1: Use Spray Varnish
If you want to evenly distribute the sealer over your entire painting, then a spray-on varnish is the way to go. Just be sure to use a sealer that is specifically designed for use with acrylic paints. First, lay down some old newspapers or anything else to protect surfaces around your work area. Next, hold the can about 12 inches away from the painting and evenly spray the surface. Allow the first coat of sealer to dry completely before applying a second coat.
Method 2: Use Brush-On Varnish
A brush-on sealer is a good option if you want more control over where the sealer is applied. Again, be sure to use a sealer that is specifically designed for use with acrylic paints. Apply the sealer to a small area at a time and then use a soft brush to spread it evenly over the surface of the painting. You can use a flat soft brush for the best results.
I am a big fan of the varnish by Amsterdam, This varnish is super soft, clear and very easy to spread. NO brushstreakes visible when applying their varnish, which I love! Amsterdam varnish comes in High Gloss, Gloss, Satin and Matt, and 3 different sizes.
Method 3: Use Resin Epoxy
Resin epoxy is a clear liquid plastic that cures into a hard, glossy finish. It is often used as a coating for wood or metal surfaces, but it can also be used to seal paintings. When applied correctly, resin epoxy will not yellow or fade over time, and it will protect your painting from scratches, UV light, and water damage. Make sure you take all safety procutions before you start.
Sealing your acrylic painting is an important step in protecting your investment and ensuring that it lasts for years to come.
