Atelier Modelling Compound (previously known as Moulding Paste) is a thick paste made from calcite grit, used for exaggerated structure and textural effects. Dries fast and waterproof with a white, matt finish. Remains flexible. Can be used with Atelier and other artists' acrylics. Water based and non toxic.
Mix with paint as an economical paint extender or to increase body by applying directly on top of paint layer for textural effect. When mixed with paint it will reduce colour intensity and gloss levels.
For more textural effects, sawdust, sand, pumice, marble dust etc. may be added.
