This reliable favourite is a general-purpose semi-gloss medium that speeds drying, improves flow and reduces brush stroke retention.


Halves the drying time of conventional oil colour (touch dry in 1-6 days depending on colour & film thickness).


Resists yellowing.


NOTE: Not suitable as a varnish or final coat.


Liquin is a durable, non-yellowing medium for thinning oil and alkyd colours and speeding drying time.


Alkyd resin medium for artists was first invented in the 1970s by Arthur DeCosta, a longtime professor at The Pennsylvania Academy of the Fine Arts in Philadelphia. DeCosta's medium, Turco Classic, was sold only locally at the Academy's school store, the Philadelphia Utrecht Linen art supply store, and one or two other privately-owned art supply stores. DeCosta believed his medium had similar qualities to Maroger medium (Jacques Maroger), the fast-drying, supposed medium of the Old Masters. Because Maroger medium must be cooked with lead, Turco lacked its inherent danger and had a similar, if not faster, drying time.


"The Kid," as DeCosta called the young man responsible for the manufacture of Turco, often made poor batches of the product and DeCosta, being a full-time professor as well as a prominent Philadelphia painter (notable for his portrait of former mayor Frank Rizzo), gave up on the enterprise sometime in the early 1980s. Since then many companies have produced similar products, Liquin being the most popular.




Liquin Oleopasto — A semi-matte, quick-drying medium, Winsor & Newton Liquin Oleopasto has a soft gel consistency with some brush drag, ideal for levelling crisp brushmarks and providing bulk in impasto and texture work. When added to paint, Liquin Oleopasto extends tube colour. When dry, it retains a knife and brushstrokes and won't level out. It dries to a crack-resistant, virtually non-yellowing film.


Liquin Fine Detail — The most fluid of the Liquin family of products, this gloss medium is ideal for fine detailed work, for producing a smooth surface picture, or in smoothly blended areas where brushmarks are not desired. The modern alternative to traditional copal mediums that were based on natural resins and offered fast-drying properties to artists, Fine Detail approximately halves the drying time of oil colour, depending on the proportions added. It is touch-dry in one to five days, depending on the climate, colours used, and film weight. It is not recommended for use as a varnish or final coat.


Liquin Impasto — This is a semi-gloss, quick-drying, non-yellowing impasto medium that retains crisp textures and brush strokes without any visible levelling. It also extends tube colour, provides bulk, and allows more blending time. When dry, it forms a flexible, tough film that can be varnished in the normal way. Use it for heavier brushwork or palette knives. It is not recommended for use as a varnish or final coat.


Liquin Light Gel — This Liquin formulation is a slight gel that breaks down on brushing (thixotropic) and flows out to give a non-drip effect when mixed with colour. It is ideal for glazing and dries to a glossy film that has increased resistance to yellowing.


Liquin Light Gel offers all the handling properties traditionally seen with the historic Meglip mediums but without the tendencies to crack and yellow that are normally associated with mastic mediums. It is not recommended for use as a varnish or final coat.


Liquin Original — This reliable favourite (formerly known simply as "Liquin") is a general-purpose low gloss medium that improves flow and transparency. It mixes easily with the brush or knife, smoothes brushwork, and is also suitable for textured oil techniques. Liquin Original approximately halves the drying time of oil colours, resulting in a drying time of anywhere from one to five days, depending on climate, colours used, and film weight. It is not recommended as a varnish or final coat.
