How to Paint with Gouache
Gouache is one of my favorite paints to paint with. It has the fluid qualities of watercolor, but the opacity of acrylic paint. What sets it apart is its lovely matte finish.
It's easy to fall in love with gouache, but there are a few things to know first.
- Gouache can be painted on colored papers since it's more opaque than watercolors.
- You can use it with watercolor paper, but it can be used on other surfaces, such as canvas, mixed media paper, and even cardstock.
Supplies Needed for Painting with Gouache
- Good quality gouache
- Palette for mixing
- Watercolor paper (or desired surface)
- Eye dropper
- Paint brush
- Water cup
- Paper towel
- Scrap paper
- Squeeze the tube onto a palette. You'll need a little more paint than if it was watercolor paint.
- Get your brush wet and mix it with the paint.
- Test the consistency on scrap paper, adding water or paint until you reach the desired consistency.
- Your first layers of paint should be thin. Let them dry thoroughly before the next layer.
Gouache Painting Tips
- Use less water than you think, especially if you're used to watercolor paint. Your brush should be wet, but there shouldn't be a puddle of water. You want the consistency of milk.
- Don't buy cheap paint. Nicer paint is easier to use. Read more about my favorite gouache paint.
- Gouache is forgiving because it's opaque. If you make a mistake, it's easy to cover up with more paint. Just let it dry before adding the new layer.
- You can paint from light to dark or dark to light. Light colors over dark colors may need more than one coat of paint or a thicker application.
- If you're going to paint in layers, the first layer should be very light so that the next layer doesn't pick up the color under it. Since gouache is water-based, it's easy to reactivate the color beneath it.
- Gouache doesn't bleed (unless it's too wet), so you can paint next to wet areas without problems.
- Gouache can be painted on top of watercolor. (I used white gouache to create stars on my galaxy painting.)
- If your painting looks too flat, try adding layers to create highlights and shadows.
- You will need tons of white gouache when mixing colors.
- If your paint color is too transparent, add a bit of white gouache to make it more opaque.

Gouache Paint FAQs
Why is gouache so expensive?
Gouache is contains a lot of pigment to give it a nice vibrant, opaque quality. Pigments cost more, so the paint will cost more. Inexpensive paint will not contain as much pigment and will not be as vibrant or opaque.
What paper do you use for gouache?
How is gouache different than watercolor?
Watercolor is translucent and uses a lot more water. Gouache is opaque and uses less water. While gouache can be used in a translucent manner, it will never be as translucent as watercolor.
For a full breakdown, see my post on gouache vs watercolors.
Can you put gouache in pans?
Yes, it's possible to put gouache in pans for portability or convenience's sake.
Squeeze the tube into each half pan and fill it halfway. Help the paint settle to the bottom by tapping it lightly. Then fill it to the top.
Not all gouaches reconstitute the same. You may find that you prefer fresh gouache out of the tube instead.
Be sure to use an empty pan set with a lid, not a mixing palette. An air-tight container is your best bet.

Can gouache be reactivated?
Regular gouache can be reactivated with water. To minimize reactivation between layers, apply a thin layer first, and let it dry thoroughly before the second layer. Then apply a thicker layer on top in the next color.
The alternative is to use acrylic gouache, which cannot be reactivated once dry.
Can I mix watercolor with gouache?
You can! They mix very well. It's a fun way to make new colors or experiment with gouache without buying a whole set. Just mix watercolors with white gouache.
How long does gouache take to dry?
Unlike watercolor, which is notorious for taking forever to dry, gouache dries very quickly. It's generally dry after 20 minutes, but of course, this depends on room temperature, humidity levels, and how much water you mixed with the gouache.
