What is Gouache Paint?
Definition
Gouache paint, also known as opaque watercolor, is a type of paint that is widely used in various art applications. It is similar to traditional watercolor paint but has a higher pigment concentration, resulting in a more vibrant and opaque finish. Gouache paint consists of a pigment, a binder, and a white filler material. It is known for its quick-drying properties and ability to create smooth, flat surfaces with bold colors.
Composition
The composition of gouache paint can vary depending on the brand and formulation, but generally, it contains the following components:
- Pigments: These are the colored particles that give the paint its hue. Gouache paints typically use high-quality pigments to achieve vibrant and long-lasting colors.
- Binder: The binder holds the pigment particles together and helps them adhere to the painting surface. Common binders used in gouache paint include gum arabic, a natural resin extracted from the acacia tree, and polymer-based binders.
- Filler Material: Gouache paint often contains a white filler material, such as chalk or blanc fixe, to increase opacity and create a more solid finish.
