Gouache can be used on canvas or paper, although I would say most artists use it on paper. Gouache and watercolors and acrylics are very similar; the primary difference between gouache and watercolors are that gouache paints are opaque and most watercolors are tansparent / translucent. This is not entirely accurate, however, because highly-diluted gouache paints are translucent as well.
Watercolor is pigment with just enough binder to retain its cake shape until reconstituted with a wet brush. It is for the most part transparent.
Gouache is pigment mixed with gum arabic as a binder and some chalk. It is essentially an opaque watercolor, but get this: You can take a gouache painting out of storage after 85 years, wet the tip of a sable brush and go back into the painting and continue blending and painting with the paint that is already there.
Gouache has this gorgeous, deep, rich, velvety texture that you will not find in any other medium. It's just nuts.
Latex or emulsion.
The ideal surface for gouache is cold-press illustration board. It is stiff and unyielding, as opposed to stretched canvas,* and has a perfect tooth. *You don't want the paint to crack and flake off when dried.
In interior or exterior house paints.... Acrylics, emulsions and latex are, oils, lacquers and shellacs are not. In artists' paints... acrylic, watercolour, gouache, and some water based airbrush paints are, oils are not..
"GOUACHE", paints, (pronounced 'g-wash') are water soluble paints in the watercolor family. Unlike traditional watercolor paint, which is translucent, gouache is an opaque medium, with a matte finish as opposed to a lustre. It can be mixed with traditional watercolor, and painted OVER watercolor, for interesting effect.
Gouache is thinned with water to the consistency of condensed milk, then applied with a natural hair (sable...) brush to illustration board. Building up layers isn't a good technique with gouache because any wet paint will interact with existing layers of already dried paint.
An aquarellist is an artist who paints aquarelles, a variety of watercolour painting.
Latex or emulsion.
Gouache
You certainly can. It absorbs very evenly into the wood. However, you will have to seal it, as the gouache could reactive or fade. I would suggest a spray clear coat.
There is little difference between many acrylics and latex paints.
The difference between a matte paint and a gloss paint are the shine once they are painted on. Gloss paints are really shiny, and matte are finishes with no glare.

Bridget Riley uses acrylics and oil paints, gouache and screenprint.
