Description

What is Cold Wax Medium?
Gamblin Cold Wax Medium a mixture of natural beeswax (wax pastilles), Gamsol and a small amount of alkyd resin. The term “cold” in Cold Wax Medium and Cold Wax Painting refers to the fact that heat is not required for working with this wax medium – as it dries by solvent evaporation (Gamsol), rather than the cooling of the wax, as in encaustic painting. As the Gamsol evaporates out of the medium, the soft wax hardens to the density of a beeswax candle.

Unlike other Gamblin painting mediums, which increase the flow and gloss of oil colors to varying degrees, Cold Wax Medium makes oil colors thicker and more matte.

Compatibility
Cold Wax Medium is compatible with oil colors, alkyd/oil colors, alkyd-based painting mediums, and Gamsol. Fast-drying mediums such as Galkyd and Galkyd Gel will increase the tack when mixed with Cold Wax Medium. Galkyd Lite Gel, our silky, soft gel medium gives the wax a smoother feel and will round the peaks of impasto. These alkyd mediums will increase the gloss level of Cold Wax (just as adding Cold Wax lowers the gloss level of these mediums). Adding Gamsol to Cold Wax Medium will make it more fluid without adding gloss.

Best Practices – FAQ about Cold Wax Medium
How much Cold Wax Medium can be safely added to oil colors?
We recommend adding up to 1/3 Cold Wax Medium to 2/3 oil colors. Beyond this amount, approximately 25% Solvent-Free Gel, Galkyd Gel or Galkyd Lite Gel could be added to 75% Cold Wax Medium. The addition of these mediums will maintain the body of your wax while also increasing both the flexibility and durability of the resulting paint layer, making it less prone to cracking. For more fluid results, you could alternatively add 25% Galkyd, Galkyd Lite or Solvent-Free Fluid.

What is the best support to paint on for Cold Wax Painting?
Just like encaustic paintings are done on rigid supports such as panels, we recommend the same for Cold Wax Paintings. Wood or aluminum panels are appropriate, as are panels with fabric adhered to the surface. Rigid supports limit movement the paint layers and will help prevent cracking.

When using Cold Wax Medium alone as a painting medium on stretched canvas, we recommend limiting the wax to 1/3 of the total paint mixture. To use higher percentages of Cold Wax Medium on stretched canvas, add 25-50% Galkyd Gel, Solvent-Free Gel, or for more fluid results, Galkyd. The addition of these mediums will increase the flexibility and durability of the resulting paint layer, making it less prone to cracking.

Are Cold Wax paintings subject to melting because of the wax?
The wax we use to formulate the Cold Wax Medium has a melting point of approximately 155 degrees F. In most environments, Cold Wax paintings will remain quite stable. However, if you need to transport or ship the painting through a warm climate in the summer, consider air conditioning!

Can Cold Wax be used as a varnish?
Yes!
