Rosa Gallery Polymerised Linseed Oil

Rosa Gallery Polymerised Linseed Oil is a professional-quality oil painting medium designed for fine art use, ideal for paint dilution, glazing and creating custom oil painting mediums. Made specifically for artists working in oil, this thick, dense polymerised linseed oil increases transparency, improves flow and extends drying time without compromising the structure of your paint.
Used to modify oil colour for glazing techniques and layered work, polymerised linseed oil enhances the optical depth and luminosity of transparent areas. Unlike traditional solvents, it dilutes paint without dissolving the binder, helping to maintain the integrity and body of the colour while improving handling and blendability.
ROSA Gallery Polymerised Linseed Oil has a noticeably heavier, more viscous consistency than standard refined oils. This makes it particularly well suited to artists who want greater control in glazing and medium formulation. Once dry, it forms a durable, waterproof film, contributing to the long-term stability of the paint layer.
