All You Need To Know About Homemade Varnish For Acrylic Paintings

Varnishing acrylic paintings is essential. Varnish protects your artwork from UV radiation and dust.

It also adds a luster to the painting, making it seem even more impressive and bringing out the beautiful colors.

Varnish comes in gloss, satin and matte finishes. People love the glossy look of gloss varnish, but you can choose a different finish.

Mixing any of these varnishes can be done to create the desired finish. However, it may take some experimentation.

We want to make it clear that you should not photograph your painting after it has been varnished. Photography will be difficult if the varnish shines in the sunlight.

Painting an Acrylic Painting

Before varnishing the artwork, make sure it is dry. The varnish will run on the canvas if it becomes too wet.

This is not the best way to achieve your desired outcome. You should also ensure that your surface is free of dirt, grime, and any other undesirable elements, such as lint.

Varnishing should be done in a separate glass container or plastic cup.

When you are painting, don't use the same jar that you used to dip your paintbrush!

This is because paint splatters will be everywhere on the inside, outside, and lip of the jar. If they get onto your varnish or your varnishing brush, these will stick to your painting.

How to Make Varnish at Your Home

You can create a basic varnish suitable for children's crafts.

Varnish can't be made at home. However, varnish purchased from an art shop can sometimes be quite expensive. It is more economical for you and your wallet.


  1. Place the furniture. Cover the work surface with newspaper or other covering to preserve it.
  2. A two-thirds glue-to-one-third water ratio is recommended. The exact amount required will depend on the size of your creative creation.
  3. Put two-thirds of the cup of PVA glue in a bowl.
  4. Add one-third of the water.
  5. Combine them well.
  6. Apply to the craft object. When dry, the varnish will be transparent. The varnish will protect artwork, decoupage and sketches as well as ornamental parts that are part of a craft project. Use a large artist's brush to apply the PVA glue varnish.
  7. Your homemade varnish is ready.

Varnish Protects Acrylic Paintings and Enhances Their Quality

Acrylics can become very flat and difficult to penetrate after drying. There may be uneven areas of shine or matte due to the use of retarders, paints, or other media.

Varnishes make colors brighter and more vivid by uniformizing the surface of the paint.

However, depending on what the artist wanted, some pieces might lose their character if they are coated with the same varnish. Artists make the final decision.

A final varnish layer is another benefit. It seals the porous acrylic painting, keeping debris from adhering.

Is Dry Acrylic Paint Porous?

After drying acrylic paints are strong and water-resistant. After drying , acrylic paints become more durable and water-resistant. However, small pores in the paint can cause dirt and dust accumulation over time.

Even if you clean and dust your artwork regularly, dirt can still get on the surface of the paint and cause permanent damage. If you hang the artwork without glass, it will also discolor over time. Sealer protects the paint surface and makes it easier to clean.

Varnish is also UV protected, which prevents paint from yellowing or fading.

Varnishing Tip

These are some things to remember when varnishing your paintings.


Allow acrylic paint to dry fully for at least a day before you apply the isolation layer (optional). Then, wait another day before varnishing.

If the acrylic paint has a thick layer, such as impasto, it is a good idea to wait for a few weeks before applying the varnish or insulating layer.


Ideal temperatures should range from 65 to 75 degrees Fahrenheit and humidity between 50 and 75 percent.

If there is too much humidity, or too low temperature, moisture can get trapped between varnish and paint layers. This can lead to whiteness or opacity.


Acrylic varnishes can be applied by spraying or brushing. Be aware of foaming, uneven coverage, particles escaping from the applicator, etc.

Let them dry flat on a clean surface, free from leaves or dust.

The Advantages of Varnishing Acrylic Paintings

  • The varnish layer provides UV protection, which prevents the pigments from fading.
  • Varnish can easily clean dirt and dust, but they are not trapped in the acrylic layer.
  • Many artist varnishes can be removed with an ammonia solution. You can use ammonia to remove a stubborn stain or to reapply varnish if it yellows over time.
  • Varnishes can be used to bring out the shine and bring together the whole painting.
  • Varnished artwork is more resistant against shipping damage and handling.

Final Verdict

It is easy to make acrylic paint waterproof. I recommend that you practice varnishing small paintings and those that have not turned out well.

You'll be able to varnish more and discover what works for you.

As long as you apply a uniform coat of varnish to your work and let it dry between each application, there is nothing to be concerned about. Good luck with your work!
