Grumbacher mediums thicken or thin paints without harming their adhesive, binding, or film-forming qualities, and allow artists to achieve increased flow and rapid or slow drying. Also proven to guard against yellowing and cracking.
Damar Liquid Varnish — This is a pure gum damar that is used to enrich dry oil paintings. Quick-drying and permanent, it provides a transparent high gloss finish that also protects oil paintings from dirt, moisture, and scuffs. When used properly, it will not “bloom” or cloud with age. Apply it when paintings are thoroughly dry (between 6-12 months). It cleans up easily with paint thinner or other mild solvents.
