Schmincke Mediums Retarder is a professional-grade additive formulated to extend the working time of oil paints, allowing artists to maintain wet, blendable surfaces for longer periods.
This 250ml bottle of retarder slows the natural drying process, giving painters greater control over color transitions, glazing techniques, and detailed blending work.
Ideal for artists who prefer a leisurely pace or work on complex compositions requiring extended manipulation time, this medium is compatible with all traditional oil painting methods.
The retarder maintains paint consistency and transparency while preventing premature skin formation on the palette.
A small amount mixed into your paint goes a long way, making this essential tool economical for both professional studios and serious hobbyists seeking superior working flexibility.
