The paints need to be thinned before using. the precise ratio of thinner to paint depends on brand and also what type of paint it is. for example mr colour (flat/gloss) paint to thinner is 1:2, whereas mr colour metallic is 1:3. knowing how much thinner to put can be a bit difficult but there are ways of testing it to be sure.
