Gouache Paint - What is It?
By: Anna Meenaghan
What is gouache paint and is it exactly the same as poster paints? Well, this really is a paint that is opaque. You can use this to reproduce materials and cards, because of this factor. I have known friends to actually scan prints to go on to make printed items.
I think it is fairly safe to say that many people are under the impression that poster paints are exactly the same, but this is not the case. Poster paint is a cheap paint consisting of proteins and a substantial amount of egg.
This creates a different type of surface and it is highly likely that you will end up with your paper wrinkling. You will find that it is very cheap, so maybe this is why it is used so much for craft projects.
It does not last all that well and often has a tendency to flake. However, it is definately a safe paint. Therefore it is used with children a lot, particularly in schools and nurseries. The fact that it is cheap makes this ideal and an added bonus in this instance.
Whereas gouache may appear similar, but this paint, as a medium, is water based. This is better than poster paint as a medium, because it gives you a better colour finish than poster paints would. Gouache paints are sold by the tube, whereas poster paints are sold in pots.
Gouache is deceiving when used, as we have all experienced, as you will find, that when they dry, they do not reflect the same colour they were when they were wet. Dark shades seem to dry lighter and light shades dry darker, in the main. They also have a matt finish.
This type of paint has, and can, be used on many surfaces and different types of papers. It is also ideal for collages and decoupage. Personally, I think, this is a good medium to use when doing landscapes on a cold pressed paper 140lb.
Paints too, are also available in permanent and extremely permanent colour, and you can see the type printed on the labels. Gum Arabic is mixed with the pigment which gives it a creamy sort of consistency which will add flow to your work. However, this depends entirely on how much chalk is in the pigment.
This is quite a useful paint to give the first wash to a picture, but you can add thicker layers at the late stages of your work. I tend to use a sable, or synthetic sable brush, on the whole with this medium. It is quite easy to get rid of mistakes and paint again.
If you apply fairly thick coats, you will not need many, or they may crack, but do not make the mistake of diluting the paint with too much water. You can also use mount board and you can preserve your paintings under glass, as long as you have a mat between the paint and the glass.
Different famous painters have used this medium, including Henri Matisse. His "Blue Nudes" being most notable. Commercial artists use this medium for posters, illustrating, advertising and general design work.
