Winsor & Newton Liquin Original is a reliable favourite, formerly known simply as 'Liquin'. It is a general purpose semi gloss medium which speeds drying, improves flow & transparency. Reduces brush stroke retention. It is also suitable for textured oil techniques. Liquin Original halves the drying time of conventional oil colours, resulting in a touch dry time of 1 to 6 days depending on climate, colours used & film thickness. It resists yellowing. It is not suitable as a varnish or final coat.
