Sennelier Gouache Binding Medium provides a matte, opaque paint that can later be reworked with water if desired.
This medium is a ready-to-use product made from natural gum, glycerin, water, and a preservative. If the resulting paste is too thick, it can be thinned with small quantities of water without modifying the paint's opacity or matte finish. For permanent colours, coat your painting with gouache varnish to protect the dry paint films.
