Ricette: Gouache

The main difference between gouache and watercolor is that all gouache is opaque. To achieve a higher hiding power, the gouache needs a higher viscosity and an increased layer/coat thickness. Since gouache usually contains more fillers the dry color appears lighter than the wet color. Gouache is less flexible and contains less binding medium than watercolours.

Lavorazione

Mix the pigments with a pallet knife with the binding agent Polyvinyl Alcohol. Passo 1: Mix the pigments with a pallet knife with the binding agent Polyvinyl Alcohol.
Grind pigment and binding medium with a muller until a soft paste is achieved. If you grind the pigments only with Polyvinyl Alcohol without additional water, it should be possible to achieve a thick, viscous paint with a good long-term stability. Passo 2: Grind pigment and binding medium with a muller until a soft paste is achieved. If you grind the pigments only with Polyvinyl Alcohol without additional water, it should be possible to achieve a thick, viscous paint with a good long-term stability.
If the paint is not sufficiently opaque, it helps to add some Chalk from Champagne (#58000) and/or Titanium White (#46200). Passo 3: If the paint is not sufficiently opaque, it helps to add some Chalk from Champagne (#58000) and/or Titanium White (#46200).

Nota

Almost all pigments are suitable for use in gouache paint. Only very coarse pigments, sands and verdigris are not recommended. Some pigments can settle during storage. If the pigments do not mix well with the Polyvinyl Alcohol, it may help to add a small amount of 1-2% Orotan (#78032) as a wetting agent. Since pigments vary as to the amount of binding medium they need to make a workable paint on a small area or to apply a test coat: If the paint shows chalking (that is the formation of fine powder on the surface of the paint film) when it is dry, it is necessary to add more binding medium. When you are ready to paint, add water as needed.
