Gouache spreads easier on hot pressed paper, but the texture of this cold pressed paper is really nice. Arches 100% cotton, 300 gsm cold pressed paper has never worked for me.
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.
Traditional gouache paints may be reactivated with water after they dry, but note that those made with acrylic binders cannot. All gouache paints work best on premium watercolor papers; because they are opaque, they also work well on colored papers.
Increase the opacity of the paint by adding less water to the gouache, creating a rich pigmented colour that will cover any pencil outlines. This technique is best for painting smaller details. Dry brushing – Dry brushing is a technique which enables you to add texture to your artwork.
You have total freedom to experiment with different brush types (like natural hair), but synthetic watercolor brushes are great for painting with gouache. The softer texture allows fluidity with the paint and the ability to create delicate detail. Pro Tip: Always carefully wash your brushes after painting with gouache.
Too much water makes it look like watercolor, and too [little] water can lead to cracking on the paint surface after it dries out.” The consistency of the paint is very important, Shah says, and that it should be “like cream that easily flows from the brush.” Not sure you've got the hang of it?
Add a small, airtight plastic container of fresh, titanium white gouache to your painting bag, in addition to the pans in your palette. Spray it with distilled water from time to time as needed to keep the fresh consistency inside the container.
As you saw in the Direct Color Mixing technique, the consistency of gouache makes it extremely blendable. Whenever you are trying to get subtle gradients of color, either on the palette or on the painting, you can achieve a wide range of colors by simply picking up a little of one color and blending it with another.
Professional artists favor gouache for its versatility. It can mimic the look and feel of acrylic, watercolor, and even oil paints!
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.
I also enjoy painting with gouache on hot-pressed watercolor paper. Gouache spreads wonderfully on its smooth surface, and the texture of the paper doesn't dominate the texture of the painting.
Why You Should Use Gouache By Itself
The paint has a lot of power when you use it alone, though. Imagine using an undercolor as your first stroke on the canvas. If you aren't careful with your watercolors, they won't stick. It will absorb right into the paper, bleed, or disappear when you add another stroke.
Cold press is absorbent and dries quickly. Hot press is less absorbent and allows for more time to adjust the paint while drying.
Honey has several known purposes as a paint additive and undoubtedly adds more desirable qualities to paint than we know. Most importantly in the case of gouache paint, honey allows the paint mixture to accept higher loads of pigment. This give gouache paint it's intense saturated color.
Cracking can usually be attributed to one of two things when using gouache: If insufficient water is used to dilute the colour, the thicker film may crack as the paint dries on the paper (note that the amount of water needed will differ with each colour).
Sarah, yes, you want the priming to be a receptive surface for the gouache. If it dries too thick and glossy, the gouache will bead up.
If you are working on heavyweight paper and do not intend to use large washes, or you are using gouache or acrylic, then you do not have to stretch the paper. But the benefit of stretching your paper is the freedom to use as much water as you want, when you want.
Is Gouache Easier Than Watercolor? While watercolor is perhaps more well known, both gouache and watercolor are common beginner mediums. Unlike oil or acrylic paints, they leave more room for error, because if you are unhappy with your initial work, you can simply rewet the paint and rework it to your liking.
If the gouache is streaky, it is too dry. If the gouache is transparent, it has too much water. You are looking for the gouache to be opaque, dark and not streaky! Pro Tip: Never let paint or water hit the metal part of your paintbrush!
Gouache is a water-based medium, so you can water down to react and move around like watercolour. Blooms can be used to add in a base of colour you can then paint on top of. I load my brush with lots of water and a little pigment then I apply it to the paper.
You can use your watercolor brushes with gouache without fear of ruining them (looking at you acrylics!), and you won't need to buy any special chemicals for clean up because, like watercolor, gouache is water soluble and can be cleaned up with water.
