LUKAS Medium 4 is a slightly reddish oil painting medium designed to produce alkyd paint from traditional oil colours. It enhances adhesion, elasticity, and flow, making it particularly effective for upper layers and glazing on dry surfaces.

This medium increases gloss and translucency while drying to a durable, turpentine-resistant finish. It remains non-yellowing over time – even in dark storage – ensuring lasting visual quality and colour integrity.
