View Full Version : Oil/Damar ratio

What is an appropriate ratio of damar to stand oil in a medium? I've tried several and have noticed that too much damar makes the paint film stay soluble a year later, whereas too little makes the paint too slippery under the brush. What is your experience with this?

i'd add some turp to this medium and you'll find that all your troubles will subside.

classic medium:

1 part damar (1 ounce)
1 part stand oil (1 ounce)
5 parts turp (5 ounces)

*cobalt drier, if you'd like (15 drops for above ratio)

a little more damar for a tackier feel, a little less for an oiler feel. up to you. but this will help with your problems of drying. its a good all around medium (if there is such a thing)...

Another "All Purposes & For Glazes Medium":
By Volume:

2 Parts Stand Oil
1 Part Canada Balsam (or Strasbourg Turpentine or Venice Turpentine
4 Parts Damar Varnish (5 pound cut)
4 Parts Pure Gum Turpentine

Mix all the ingredients and shake well. You may need to heat the Canada Balsam (or Strasbourg Turps or Venice Turps) in a double-boiler just slightly to reduce its viscosity.
This is a good medium amd dries well. You can play with the volume of turpentine. Less turps makes it more viscous and resin rich, more turps makes it obviously less rich and less viscous.
