Natural wetting agent for water-colours and gouache colours. Decreases the surface tension of the colours diluted with water. Use sparingly. Dissolved oxgall tends to flocculate during a long period of torage. This has no influence on the product`s handling.

Impasto can be mixed with any pigment to obtain any watercolor color. It also acts as a thickener for tubed watercolor paints. It limits color flow and improves gloss. It increases the adhesion of lightweight collage materials such as textiles, silk, paper, pigments, and sand. The collage effect weakens with greater dilution. Impasto remains water-soluble.
