What Are the Types of Varnish for An Acrylic Painting?

1. Acrylic Resin Varnish vs. Acrylic Polymer Varnish

a). Acrylic Resin Varnish

Acrylic resin varnishes are typically glossier, clearer, and stronger than acrylic polymer varnishes. Therefore, if you want your acrylic painting to have a high-gloss finish, use the acrylic resin varnish.

One thing to note is that you should always use an isolation coat over your acrylic painting before putting on the varnish. This protects your beautiful work of art from getting altered. Also, the isolation coat is extremely important when you're applying a satin or matte varnish.

You can make the isolation coat using two parts of your varnish of choice and one part of water. Once the isolation coat is well-dried, you can start applying the varnish. If you don't apply this coating and then apply a satin or matte varnish, you may get a slightly cloudy finish.

A disadvantage of using acrylic resin varnishes is that they are harmful if inhaled. Therefore, always ensure that you are working in a properly ventilated area. Use mineral spirits to clean your brush once you're done to thin the varnish and clean it off.

b). Acrylic Polymer Varnish

The best thing about these varnishes is that they are non-toxic. So you don't have to worry about inhaling toxic fumes as you work. Just as with the resin varnish above, apply the isolation coat if you intend to use a satin or matte varnish.

Another perk of acrylic polymer varnishes is that you can easily wash your brushes using soap and water.

2. Gloss, Satin, or Matte Varnish

a). Gloss Varnish

If you want your finished painting to have a shiny and glossy finish, go with this varnish. This glossy finish brings out the colors in your painting and makes your whole piece brighten up. Also, you'll notice the reflections from light hitting the surface.

b). Satin Varnish

You could say that the satin finish is the middle ground between the glossy finish and the matte finish. When you apply varnish to your acrylic painting, you'll notice that it gains a satiny appearance.

It won't be as glossy as the one above but not flat either. Both the satin varnish and matte varnish soften the colors on your painting. Use satin varnishes for a clean and cool satin finish.

c). Matte Varnish

Matte finishes are flat and the opposite of the gloss varnishes. Your acrylic painting canvas won't have the same shine as the glossy finish, but it won't be dull either. It will just look flat. If you have a bright color painting and you want to give it a softer effect, use this varnish.

If you don't want either of these finishes, in particular, you can always layer them or mix up the varnishes to get the look you want. For example, satin and matte varnishes can go well together.

What Are Advantages of Varnishing An Acrylic Painting?

1. Saturates the Colors

Deepening the colors on the painting is a major reason why varnishing acrylic paintings is important. For example, using a varnish that leaves a glossy surface can make your colors look brighter and your painting pop.

Your painting will have a permanent enrichment of its colors. The truth is that most paintings end up looking dull after the wet surface dries. A good resin-based varnish or another varnish can keep this from happening.

2. Gives an Even Gloss/Satin/Matte Finish

We looked at the various types of varnishes and their effect on your artwork. You can also mix up these different finishes to get one that suits you best. You can also choose to apply different varnishes in various areas.

If you have bright colors and don't want them to pop too much, you can use the matte varnishes. Remember to apply the isolation coat first. This allows you to easily remove and replace your varnish when the time comes without ruining your painting.

Nonetheless, if you have an oil painting, you don't have to apply an isolation coat before your resin or polymer varnish.

3. Protects Your Painting

Last but not least, we have one of the major reasons you should apply a layer of varnish. If you have used acrylic or oil paint, you know that acrylic paint is quite soft. Therefore, if the surface of your painting is not completely dry and you dab it with your finger, you risk disturbing it.

Therefore, protecting this surface with a good water-resistant varnish will add an extra layer of protection. You also get to protect your painting from ultraviolet light, dust, heat, humidity, dirt, and other environmental factors.

Frequently Asked Questions (FAQs)

1. What does an isolation coat do?

An isolation coat physically separates your painted surface from the varnish you're applying. It keeps the varnish and paint layers separate. The advantage of applying this coating is that your acrylic painting will remain protected if you wish to remove the varnish down the line.

The isolation coat also protects your acrylic painting from the solvents you'll use to remove the varnish.

2. How long does acrylic varnish last?

Depending on the type and quality of varnish, it lasts about 12 months. Nonetheless, if you feel the need to add another coating for protection, you can always do that. You can apply another coat every 8-12 months, depending on the state of the previous coating.
