We’ll look at different types of varnishes and their benefits, as well as discuss some common misconceptions about using varnish on acrylic paintings. So grab your brushes and let’s get started!

What is acrylic paint?

Acrylic paint is a type of water-based paint that contains pigment particles suspended in an acrylic polymer emulsion. The polymer acts as a binder, holding the pigment particles together and allowing them to adhere to surfaces like canvas, paper, or wood. Acrylic paints are known for their quick-drying time and versatility, making them a popular choice among artists of all skill levels.

Acrylic paints were first developed in the 1940s by several companies, including Liquitex and Rohm and Haas. They quickly gained popularity among artists due to their fast drying time, water resistance, and ability to be used on a wide variety of surfaces. Today, acrylic paint is available in many different colors and consistencies, from thin washes to thick impasto textures.

Composition of Acrylic Paint

Acrylic paint consists of three main components: pigment particles, a binder medium, and solvents. The pigment particles are responsible for giving the paint its color and opacity. The binder medium is typically an acrylic polymer emulsion that holds the pigments together after they are mixed with water or other solvents. Solvents such as water or alcohol are used to thin the paint or clean brushes.

Uses of Acrylic Paint

Acrylic paints can be used on a variety of surfaces including canvas, paper, wood, metal and plastic. They can be thinned with water or specialized mediums to create washes or glazes or applied directly out of the tube for thick impasto effects. Acrylics dry quickly which allows layers to be built up quickly without waiting for previous layers to dry completely.

How does acrylic paint differ from other types of paint?

Acrylic paints differ from other types of paint in several ways:

Drying Time

One significant difference between acrylic paint and other types of paint is the drying time. Acrylics dry much more quickly than oil paints, allowing artists to build up layers of paint faster without having to wait for each layer to dry. Watercolors also dry quickly, but they have a less opaque finish than acrylic paints.

Water Resistance

Acrylic paints are water-resistant once they dry, which makes them ideal for outdoor use or in areas with high humidity. This feature also allows artists to create mixed media pieces that include both wet and dry media.

Versatility

Acrylic paints can be used on a wide variety of surfaces, including canvas, paper, wood, metal, and plastic. They can be thinned with water or specialized mediums to create many different effects, from thin washes to thick impasto textures.

Clean-Up

Acrylic paints are easy to clean up with soap and water while still wet. Once dried, however, they become difficult to remove from surfaces such as clothing or furniture.

What are the benefits of using acrylic paint?

There are several benefits of using acrylic paint:

Drying Time

One significant advantage of using acrylic paint is its quick-drying time. This allows artists to work faster and build up layers of paint more quickly without having to wait for each layer to dry completely.

Water Resistance

Acrylic paints are water-resistant once they dry. This makes them ideal for outdoor use or in areas with high humidity. It also allows artists to create mixed media pieces that include both wet and dry media.

Easy Clean-Up

Acrylic paints are easy to clean up with soap and water while still wet. This reduces the need for toxic solvents such as turpentine that are required when working with oil-based paints.

Colorfastness

Acrylic paints are highly resistant to fading over time, making them a great choice for creating artwork that will be displayed in areas with lots of light exposure.

Versatility

Acrylic paints can be used on a wide variety of surfaces, including canvas, paper, wood, metal, and plastic. They can be thinned with water or specialized mediums to create many different effects, from thin washes to thick impasto textures.

What is varnish and what does it do?

Varnish is a clear protective coating that is applied over a finished painting. It is typically made from either resin or synthetic materials and can be either glossy or matte in appearance. Varnish serves several purposes:

Protection

One of the primary purposes of varnish is to protect the surface of the painting from dust, dirt, and other environmental pollutants. It also helps to prevent damage from UV light exposure.

Enhancement

Varnish can help to enhance the colors in a painting by providing a more even finish that reflects light uniformly across the painted surface.

Durability

Varnish helps to increase the durability of a painting by preventing scratches and other damage that can occur during handling or transport.

Gloss vs Matte Varnish

Gloss varnish provides a shiny finish that enhances the vibrancy of colors while matte varnish provides a more subdued finish that reduces glare and reflections.

Is it necessary to apply varnish to acrylic paint?

It is not strictly necessary to apply varnish to acrylic paint. However, there are several reasons why an artist might choose to do so:

Protection

As with any artwork, acrylic paintings are subject to damage from environmental pollutants, UV light exposure, and handling. Applying a varnish can help to protect the surface of the painting from these factors.

Enhancement

Varnish can help to enhance the colors in an acrylic painting by providing a more even finish that reflects light uniformly across the painted surface.

Durability

Varnish helps to increase the durability of an acrylic painting by preventing scratches and other damage that can occur during handling or transport.

Longevity

Applying a varnish to an acrylic painting can help to extend its lifespan by creating a barrier between the paint and the environment.

What are the potential consequences of not applying varnish to acrylic paint?

There are several potential consequences of not applying varnish to an acrylic painting:

Fading

Acrylic paints are highly resistant to fading over time, but they are still subject to damage from UV light exposure. Without a protective coating like varnish, an acrylic painting may fade or discolor over time.

Dirt and Dust Accumulation

Unvarnished paintings are vulnerable to dust and dirt accumulation. Over time, this buildup can become difficult or impossible to remove without damaging the paint layer underneath.

Damage from Handling

Paintings that are not protected by a varnish coating are more vulnerable to damage from handling or transport. Scratches, smudges, and other blemishes may be difficult or impossible to remove without damaging the underlying paint layer.

Reduced Longevity

Without protection from UV rays and other environmental pollutants, an unvarnished acrylic painting is likely to have a shorter lifespan than one that is properly coated with varnish.

How do you apply varnish to acrylic paint?

Here are some steps to follow when applying varnish to an acrylic painting:

Step 1: Prepare the Painting

Make sure that the painting is completely dry before applying varnish. If necessary, clean the surface of the painting with a soft brush or lint-free cloth.

Step 2: Choose a Varnish

Select a varnish that is compatible with acrylic paint. Matte or glossy finishes are available, depending on your preference.

Step 3: Apply the Varnish

Using a clean brush or spray bottle, apply a thin layer of varnish to the surface of the painting. Work in long, even strokes and be careful not to overapply.

Step 4: Allow to Dry

Allow the first coat of varnish to dry completely before applying additional layers. Follow the manufacturer’s instructions for drying time.

Step 5: Apply Additional Coats (Optional)

If desired, apply additional coats of varnish until you achieve the desired level of protection and finish.

Step 6: Let Dry Completely

Allow the final coat of varnish to dry completely before handling or framing the painting.

Are there different types of varnish that work better with acrylic paint?

There are several types of varnish that work well with acrylic paint:

Solvent-Based Varnish

Solvent-based varnishes are typically made from resins dissolved in solvents such as turpentine or mineral spirits. They provide a durable finish that is ideal for protecting large paintings or outdoor installations.

Water-Based Varnish

Water-based varnishes are made from synthetic materials and can be thinned with water for easy application. They provide good protection for smaller paintings and indoor installations.

Spray Varnish

Spray varnish can be applied in thin, even coats with minimal brushstrokes. This makes it an ideal choice for artists who want to achieve a uniform finish without visible brush marks.

UV-Protective Varnish

UV-protective varnish contains additives that help to protect the painting from damage caused by UV light exposure. This is especially important for acrylic paintings that will be displayed in areas with high levels of natural or artificial light.

In conclusion, while it is not necessary to varnish acrylic paint, doing so can enhance its overall appearance and provide additional protection against wear and tear.
