What s an additive?
Additives are used to adjust the chemistry of acrylic paints, and they don t include a significant proportion of acrylic resin. The last part of that sentence is important because it means that additives should be used only in the amount needed to achieve the desired effect; adding too much can affect the stability of the paint film. They can be used to adjust the flow, or drying time of the color. Additives are labeled with a large letter A. As with all products, the directions should be read before use.
