Winsor and Newton Flexible Modelling Paste is a fine texture paste with, yet thick, sculptural consistency. It’s a lighter-weight modelling paste for use on canvas to minimize sagging. Depth can be built up in layers by allowing it to dry. Suitable for building multiple layers with matt finish. May be over- painted. Colour may be added directly to modelling paste, but colour will become lighter and more chalky and the resulting paste will have reduced body.
