Gamblin Cold Wax Medium 16 oz — soft oil-free paste for matte finish and increased body

Gamblin Cold Wax Medium (16 oz) is a soft, oil-free paste that thickens oil paints, creates a matte surface, and can be applied as a wax varnish over fully dry oil paintings.

Made from naturally white unbleached beeswax, alkyd resin and Gamsol, this knife-consistency cold wax lets painters build texture, reduce gloss, and alter handling without adding drying oils. Because it contains no oil, it can be used either as an additive to oil color (when blended with Gamsol) to increase stiffness and body, or as a protective wax layer over a thoroughly dry painting. Follow recommended ratios to avoid brittleness and potential cracking.

How does Gamblin Cold Wax Medium change paint handling?

Added to oil color, the medium increases body and tooth for impasto and knife work while reducing gloss for a velvety finish. It’s formulated to give a thick, workable paste consistency that retains peaks and strokes from palette knives.

• Add with Gamsol to disperse the wax into paint for even consistency.
• Use small amounts—no more than one-third of total paint volume to minimize cracking risk.
• Improves lift and tooth for scumbling, scraping, and textural layering.
• Maintains color saturation while lowering gloss level.

Can I varnish a finished painting with this cold wax?

Yes — once your oil painting is completely dry, apply a thin wax coat to shift sheen and surface feel without adding oils. Because the product contains no oil, it functions as a wax varnish rather than a traditional oil varnish.

• Apply only to fully cured paint layers—ensure adequate drying time per Gamblin guidelines.
• Use sparing, even layers to avoid uneven build-up.
• Test on a sample panel first to check appearance and compatibility.
• Can be buffed lightly after drying for a subtle sheen if desired.

What mixing and safety steps should I follow?

Blend the cold wax with Gamsol before combining with paint for a smooth, workable mixture. Keep proportions conservative and work in a well-ventilated area when using solvents like Gamsol.

• Mix cold wax with Gamsol to achieve the desired softness and spreadability.
• Limit cold wax to no more than 33% of the final paint volume to reduce cracking risk.
• Store container tightly closed and at moderate temperatures to maintain consistency.
• Observe standard solvent safety: ventilation, gloves, and disposal per local regulations.

Who is this for? Gamblin Cold Wax Medium 16 oz is designed for oil painters who want to add tactile, matte surfaces and stronger body to their colors — especially artists working in impasto, palette-knife techniques, mixed-media oil studies, or those seeking a low-gloss wax finish over a finished, dry painting. Its oil-free formula also appeals to conservators and experimental painters who need a non-oiling top coat or a stiffening agent for sculptural paint effects. Product code GB03016 identifies this size and formula.
