Gamblin Galkyd Painting Medium for Oil Colours

If you work with oil paints and want to adjust their flow, transparency and finish, Gamblin Galkyd offers a practical way to modify how your colours behave. It helps thin oil colours, increase gloss and create more transparent paint layers without relying on oil alone to change the consistency.

Galkyd is especially useful for glazing and smooth, controlled applications. When used in greater proportions with oil colour, it helps level brushstrokes and create an enamel-like finish. Its fast-drying properties also make it useful when you want to move through painting stages more quickly.

Whether you are working on detailed paintings, layered compositions or smooth passages of colour, Galkyd gives you another level of control over your oil painting process.
