ABOUT GOUACHE:

• Gouache paint is similar to watercolour, but it is opaque & a versatile medium. It is often described as an “opaque watercolour”. 
• Gouache is made up of natural pigment, water and a binding agent (like gum arabic or dextrin). 
• Gouache can also be used as ‘watercolours’ if diluted with water but will not look very vibrant.
• Gouache when mixed with a little and the right amount of water gives a very vibrant, rich and opaque finish to the final painting.
• Gouache is thick and dries quickly. However, even if the paint dries, it is easier to re-wet the paint, unlike acrylics, by spraying or adding little drops of water.
• When gouache dries it gives a matte finish. It is non-shiny and non-reflective. 
• The main advantage of gouache is that it can be layered and reworked, unlike watercolours. 
• If there is a small mistake in the painting, it will be very difficult to correct when using watercolours because of its transparent nature.
• However, Gouache, when it dries, becomes opaque and hence it is easier to correct mistakes in gouache paintings as you can layer a darker colour over a lighter colour and vice-versa when using gouache.
• The base layer needs to be dry before you apply the next layer of paint.
• Gouache, being a versatile medium, works well on any watercolour paper with a fine texture, drawing papers (140 GSM & above), stretched canvas, MDF board, cardboard, wood & toned colour paper.
