M. Graham : Artists' Oil Medium : 237ml : Walnut Alkyd Oil Medium

M. Graham Walnut Alkyd Medium is a concentrated painting medium formulated to thin oil colour, accelerate drying, enhance adhesion between layers, and increase surface sheen and flexibility. Crafted from walnut oil and an alcohol-based alkyd resin, it remains essentially non-yellowing and completely solvent-free.

This non-toxic medium supports a more durable painting surface by improving the bond between paint layers and the painting surface. It is designed to be mixed directly with the paint and is fully compatible with all professional oil colours and mediums, especially M. Graham Artists' Oil Paints.
