Acrylic gouache, unlike traditional gouache, is an opaque, matte acrylic paint. It is truly the best of both worlds in that it is waterproof once dried, whereas gouache paints are not. Acrylic gouache painting lasts longer than a typical gouache painted piece and, like acrylic paints, dry quickly.
Gouache is more delicate than acrylics and it's prone to water damage. But that can also be an advantage when you need to rework an area. In a way, it's a little more traditional than acrylics because you're basically limited to working on paper or illustration board.
Acrylic has a tendency to have a glossy or satin finish, whereas gouache is matte. Acrylic gouache is essentially acrylic paint which contains an additive givivg it a matte finish similar to gouache. It still has sort of a plastic look, however, and it is somewhat water resistant when dry, unlike true gouache.
When dry, acrylics have a shiny, glossy appearance, while gouache is soft and flat. Acrylic paint can be applied thickly enough to create interesting surface textures, while gouache paint dries flat and matte.
Acrylic paints can be displayed more easily as it is more durable than gouache, which is more delicate and offers more of a matte, velvet finish. Gouache is expensive but is more natural than acrylics and is easy to work with. This paint also only needs some water to clean up.
Why is gouache unpopular? Gouache is not as popular as acrylic because it is more expensive to purchase, and is less water-soluble. However, many artists prefer to use gouache because of its unique properties and attractive matte finish.
Professional artists favor gouache for its versatility. It can mimic the look and feel of acrylic, watercolor, and even oil paints! So how do artists work with gouache paint to create beautiful paintings? Let's explore and see!
Gouache is workable and reworkable unlike any other paint. Because it is water-soluble, a wet brush can go back to soften edges or lift colour even after the paint dries . It is important to note that new layers reactivate previous layers of paint.
Happily, gouache is versatile and works well on both paper and canvas which is ideal if you have a preference towards one or the other. For gouache painting on paper, Reeves watercolour paper is perfect; it is designed to take water-media already and is robust enough to handle this heavier type of paint.
You can mix acrylic paints with gouache on the same canvas or even fabric, and the proper way to do that is by using a hybrid of the two kinds of paint. The result is called acrylic or acryl gouache, and a matte finish characterizes it. Also, it is smoothly applied, giving you the best out of the two paint types.
Gouache (pronounced “gwash”) is a water-soluble paint that combines the best aspects of both watercolors and acrylics for a paint that's versatile and easy to use. Because it can become transparent when thinned with water, it acts like watercolor paint.
Both gouache and watercolour are known as great beginner mediums. So when you are starting with painting you might have been introduced to both.
The gouache definition is simply a technique of painting with opaque watercolors. Gouache is known as opaque watercolor paint because it's typically mixed with water in the same way the watercolors are, but it provides a flat, matte wash of bold color.
Varnishing a gouache painting should be avoided, because the varnish drastically affects the depth, darkness and finish of the work. And should anyone want to retouch the painting again at some point in the future, perhaps for restoration purposes, the varnish will not come off.
Paper or other surface to paint: Gouache works well on watercolor paper, but you could also use some thick drawing paper. While you can use canvas, that's typically better suited for acrylic.
When painting with Gouache, a synthetic brush is ideal - meaning the bristles are soft and smooth, versus course and stiff (bristles that feel like horse hair).
Once the paint surface of your gouache painting is sealed with watercolor varnish, you can apply an isolation coat to it. This coat will create a permanent barrier. Any varnish added after this coat can be removed safely. Most removable varnishes can be removed with turpentine or mineral spirit.
You can use gouache straight from a tube or mix it on a palette. It can be watered down to look like watercolour or be applied opaque like acrylics.
The disadvantages of working with gouache are that the wet colors do not match the dry colors (the colors brighten as they dry, so you have to paint the picture as though it was really dark), and you cannot overpaint.
Gouache is absolutely perfect for this because it dries to a super matte finish. This means that you never get a glare or any light reflecting off the paint surface, so the colour always looks so vivid in photos.
After the masking fluid is completely dry, the masked picture areas can be painted over using water-colours, gouache colours or AERO COLOR® Professional.
The Mannerist Paolo Pino (1525—1587) was the first to use the technique of combining gouache and watercolours in creating paintings.
Gouache dries very fast and has the ability to become transparent enough to be used in a technique called glazing. By thinning the paint with water, you can layer it on top of painted areas that are dry to enrich an existing color or create a new one.
If you've never heard of it, Gouache (pronounced gwaash) is the slightly misunderstood paint that essentially works as an opaque watercolor.
