Atelier Moulding Paste is a very thick, textural paste can be used to create exaggerated structure within artwork. Atelier Moulding Paste offers the same flexibility as Atelier paints, and can be used at any stage in the painting process. You will see that then the paste dries white. Atelier Moulding Paste can be mixed with paint for a coloured ground, or paint over it after it dries.
