Gamblin, founded in 1980, is a paint, medium, ink, and solvent producer from Portland, Oregon with a popular line of products intended for professional artists. The company is revered by oil painters, who appreciate Gamblin for its commitment to quality and safety. The enthusiastic demand for Gamblin oil painting mediums is one of the main reasons Jackson’s carries their range of products. The mediums pair perfectly with Gamblin Artist Oil Colour and are suitable for all oil paint. Artist David Schroeter has used Gamblin mediums for many years.
Gamblin Oil Painting Mediums by David Schroeter
I’ve been using Gamblin oil painting mediums for ten years and consistently utilise them in my studio. My first experience working with a Gamblin product was trying their Galkyd alkyd resin which dried my brush marks quickly and allowed me to layer prodigiously. The Galkyd Lite allows me to paint quickly with thin, translucent layers while the Cold Wax Medium gives the paint a soft matte texture.
Galkyd Lite increases fluidity and transparency and reduces drying time.
Galkyd Lite has a thin, runny consistency – similar to more traditional mixed glazing mediums. It is composed of Gamblin Galkyd alkyd resin, and can be further thinned with their odourless mineral spirit, Gamsol. Compared to the regular Galkyd medium, Galkyd Lite feels less thick and resin-like and more like linseed oil. A similar product is Winsor & Newton Liquin Fine Detail.
When mixed with oils, Galkyd Lite increases fluidity, transparency, and gloss. A little can go a long way because of its strong thinning properties. On the painted surface, the resin allows for clarity and refraction as well as creates a glossy lustre. These properties make it excellent as a glazing medium. Using small amounts will allow you to retain brush strokes.
The alkyd resin also dramatically reduces drying time. Thin layers will be touch-dry in 24 to 30 hours. This gives you all the more opportunity to quickly build up thin, transparent layers of paint – like faster traditional glazing.
The drying properties of the resin means Galkyd Lite could require some maintenance to make sure it doesn’t thicken or dry in the bottle. Make sure to keep the paper liner in the Gamblin bottle cap as this keeps the bottle airtight. Adding small amounts of Gamsol after each use will allow the medium to keep its consistency. Decanting only small amounts at a time will prevent a resin skin from forming over the pots.
Gamblin Cold Wax Medium
Gamblin Cold Wax Medium increases thickness and reduces gloss.
Gamblin Cold Wax Medium is a thick, white painting medium with the buttery consistency of wet wax. The medium is made from naturally white beeswax combined with Gamblin’s odourless mineral spirit, Gamsol. It can be further thinned with Gamsol or combined with Galkyd or Galkyd Lite for greater paint flexibility.
The cold wax medium mixes nicely with oil paint, giving it a full, thick texture while only affecting the colour with a certain softness. The fullness of the paint allows for expressive impasto work. The surface of the dried paint will reach the consistency of a wax candle so if you’re using more than 1/3 medium to 2/3 paint, rigid supports are recommended to avoid cracking.
The medium also has the unique property of increasing the matte quality of paint. Mixing the cold wax medium (up to 1/4) into another Gamblin oil painting medium like Galkyd Lite makes it act like a matting agent, reducing natural glossy effects. To mix with fluid mediums, thin the cold wax medium with Gamsol until it becomes a wet paste and combine thoroughly. For thicker mediums like Galkyd Gel, simply blend it in with a palette knife. It can also be brushed onto a dried painting as a waxy varnish.
