Winsor & Newton Liquin Original Medium 500ml - Faster Drying Oil

In this review of the Winsor & Newton Liquin Original Medium 500ml the bottom line is simple: this product is for oil painters who need reliable faster drying without compromising long-term color stability. The reviewer found Liquin Original halves the drying time of conventional oil color, becoming touch dry in as little as one day depending on pigment and film thickness, which speeds layering and reduces waiting between glazes. It is not a varnish or final coat, but as a studio medium it delivers consistent handling and helps resist yellowing in finished work.

Key Features

• Speeds drying: Halves the drying time of conventional oil color so painters can rework or glaze sooner and complete layered work faster.
• Touch dry window: Paint films can be touch dry in 1 to 6 days depending on color and film thickness, allowing for flexible workflow planning.
• Color stability: The formula resists yellowing compared with some traditional oils, preserving midtones and highlights over time.
• Studio medium: Designed for mixing into oil paint rather than as a final protective coat, so it alters handling without replacing varnish.
• Generous bottle size: The 500ml bottle offers plenty of medium for regular studio use and reduces the need for frequent repurchasing.

Who It's For

The Liquin Original 500ml is aimed at dedicated oil painters, illustrators and fine art students who use glazing, scumbling or layered techniques and want to shorten drying intervals between layers. Those who produce commissioned work on deadline or who prefer working alla prima but need occasional faster set times will also find it useful.

It is less suitable for artists seeking a non-yellowing final varnish or a medium marketed as a permanent topcoat; Liquin Original is explicitly not a varnish and should not be used as the final protective layer on finished paintings.

Pros & Cons

Pros

• Speeds drying substantially so artists can work in more frequent layers or finish paintings faster.
• Helps resist yellowing compared with untreated oil films, aiding long-term appearance.
• Large 500ml bottle provides good value for regular studio use.

Cons

• Not suitable as a varnish or final coat, so a separate final varnish is still required for protection.
