A medium and varnish rolled into one. This medium does nearly all the techniques that you need if you are painting in fast quick layers. However, if you want Heavy Impasto you will still need to use Heavy Gel or Moulding paste. It gives the colour saturation and enhancement of a good solvent based varnish. Varying levels of sheen can be achieved by adding water to the concentrate. To apply, place your painting in a sloping position so that you can pick up the runs or dribbles. You can work back and forth while the varnish is wet because it does not catch on the brush.
