Oil Painting Mediums

Mediums are additives which alter or enhance the characteristics of the colour. They are used to change the rate of drying, increase gloss, improve flow, provide texture etc. Mediums are based on the binders used in milling the colours: linseed oil, alkyd resin and modified oils for water mixable oils.

All mediums should be used in moderation; they are intended only as an additive to the colour. In addition, you should avoid adding multiple mediums to the colour. The most stable film is likely to contain a single medium.

Artists' Painting Medium (Winsor & Newton)

 

This is a prepared medium that thins the colour consistency, improves flow and wetting, slows drying, increases the durability of the film and is resistant to yellowing. Artists' Painting Medium is well suited for 'oiling out'.

 

 

Liquin Original (Winsor & Newton)

This reliable favourite (formerly known as just "Liquin") continues to be a popular liquid alkyd medium. A general purpose low gloss medium which improves flow and transparency. It mixes easily with the brush or knife and smooth’s brushwork. Liquin Original also suits a textured oil technique.

 

 

Liquin Impasto Medium (Winsor & Newton)

A semi-gloss, quick drying, non-yellowing impasto medium.  It retains crisp textures and brush strokes without any visible levelling and extends tube colour and provides bulk. It also allows more blending time.

When dry, it forms a flexible, tough film that can be varnished in the normal way. Liquin Impasto and Liquin Oleopasto are the only mediums that safely thicken oil colour.

 

Liquin Fine Detail Medium (Winsor & Newton)

 

The most fluid of the Liquin family of products, this gloss medium is ideal for fine detailed work. It is also perfect for producing a smooth surface picture or in smoothly blended areas where you do not want brush marks.

 

 

Liquin Light Gel Medium (Winsor & Newton)

This Liquin formulation offers a slight gel that breaks down on brushing and flows out to give a non-drip effect when mixed with colour. It is ideal for glazing. It dries to a gloss film that has an increased resistance to yellowing and looser handling while painting.

 

 

Liquin Oleopasto Medium (Winsor & Newton)

 

Liquin Oleopasto Medium is a semi-matt, quick drying, non-yellowing impasto medium. It has a soft gel consistency with some brush drag, levels crisp brush marks, extends tube colour and provides bulk.  This stiff, translucent gel is specifically for impasto and texture work. It dries to a crack-resistant and virtually non-yellowing film; it retains knife and brush strokes and will not level out.

 

Artisan Water Mixable Fast Drying Medium (Winsor & Newton)

 

This is a fast drying medium that improves the flow and speeds the drying of Artisan oil colours, smoothes brushwork and increases gloss and transparency. It is excellent for glazing and producing fine detail and is resistant to yellowing.This is a very popular medium as it speeds the drying of oil colour by about 50%, allowing further layers to be applied more quickly.

 

Artisan Water Mixable Painting Medium (Winsor & Newton)

 

This medium thins the consistency of Artisan oil colours and aids fine detail work. It also improves the flow and wetting of the colour. It dries slowly to a flexible film and is good for "oiling out."

 

 

Artisan Water Mixable Impasto Medium (Winsor & Newton)

 

This is an impasto and texturing medium for use with Artisan oil colours.

This medium also helps to speed the drying of the colours.

 

Poppy Oil Refined (Old Holland)

Obtained from the first pressing of poppy oil and is used to increases the fluidity of the paint. This makes it possible to remove the brushstrokes. Increases the gloss, but lengthens the drying time. Can be diluted with turpentine and white spirit.

Yellows less than linseed oil, but dries slower.

Alkyd Flow Medium (Daler Rowney)

 

Slightly thinner than Alkyd Gel, it increases the transparency and flow of oil colour, allowing paint to be brushed out more smoothly. Reduces drying time.

 

Painting Medium (Daler Rowney)

An ideal all-purpose painting medium made of Linseed Stand Oil, White Spirit and Oil of Spike Lavender, which dries to a tough elastic film. Easy to handle it’s a perfect oil painting medium for beginners, and creates an excellent glaze.

Stand Oil (Old Holland)

Boiled, polymerised linseed oil. This is used to increases the fluidity of the paint and makes it possible to remove the brushstrokes. Increases the gloss, is elastic, but lengthens the drying time. Can be diluted with turpentine and white spirit.
 
Yellows less than linseed oil, but dries slower. Can be used in the glacis technique.

Cold pressed Windmill Linseed Oil (Old Holland)

Oil from linseed cold-pressed in a windmill.  Increases fluidity and makes it possible to remove the brushstrokes. Increases the gloss, but lengthens the drying time.
