How to choose between gouache and acrylic paint

How to choose between gouache and acrylic paint for beginners?

Both are good for beginners, they seem to be less intimidating than oil painting, but which one to choose?

What they have in common

Both are opaque medium, meaning that you have white paint covering a colored background (unless watercolor where the white is the paper itself).

Both are diluted with water.

Both are water washable.

Both have bright colors and can be found easily in art stores.

Binder, what holds the pigments together


A polymer is used, kind of magic if you think about it. In the tube it’s fresh and creamy, and once on the paper it’s solid and waterproof.



Arabic gum is used in gouache, as in watercolor. It’s a binder that allows the paint to be reactivated once dry.

You can also use a drop or two of arabic gum in your dry gouache to make it creamy again.

Water resistance


Once it’s dry, it’s forever! Either on paper, on the palette or inside the brushes. 

So you’d better be quick when cleaning your stuff.


It can be reactivated once dry. Good for fixing mistakes on the paper for example, or cleaning your brushes and palette. 

But it’s also fragile, as any drop of water on the finished painting will leave a mark.

Dust resistance


The acrylic binder makes a protective surface on the paper. You can hang your acrylic painting without a glass, it will be okay for a long time. 


Due to the matte finish and the lack of polymer in the mix, the surface is subject to hold dust.

You’d better frame your art behind a glass to protect it.



You can get different thickness, add medium and gels for more texture. It can go from very thin, transparent to impasto, with strong brushstrokes.


You can dilute with water until you get watercolor. You can go thick.

But too thick and the paint will crackle.

Surface sheen


Anything, really.

The classic acrylic is between shiny and glossy, depending on the brands.

You can get matte finish too, this is called Acryla Gouache. A bit confusing as this is acrylic with a matte finish, not gouache!


Matte finish. This is great to take pictures of the finished painting as you won’t have any reflections on it.

You can apply a varnish on top to get a shiny effect though.

Substrates to paint on


Virtually anything: paper, cardboard, wood, glass, metal… it’s really endless.


Paper of all kind.

Cardboard, wood with a layer of gesso behind and it will be fine.
