Used to alter or enhance the characteristics of oil colour, Mediums are used to modify the rate of drying, increase gloss, improve flow or add texture. Based on the binders used in milling the colours (e.g. linseed oil, alkyd resin and modified oils for water mixable oils), mediums should be used in moderation as an additive to the colour; we also recommend avoiding adding multiple mediums to oil colour.

A slow drying, gloss medium, it reduces the viscosity of oil colours. Ideal for fine detail work, glazing and smoothly blending areas with no brush marks, it increases the durability of the paint.
