This is a semi-gloss, quick-drying, non-yellowing impasto medium that retains crisp textures and brush strokes without any visible leveling. It also extends tube color, provides bulk, and allows more blending time. When dry, it forms a flexible, tough film that can be varnished in the normal way. Use it for heavier brush work or palette knives. It is not recommended for use as a varnish or final coat.
