For a more economical Gesso, replace the Rabbit Skin Glue with some already prepared Fish Glue. Add some lukewarm water to lighten the Fish Glue.
Glue preparation :
In 1 liter of cold water, add 100 g of Rabbit Skin Glue grains (let swell for 12 hours), heat in a “Bain-Marie” while stirring with a wooden spoon (ideal temperature is 40 to 50 °C), the glue must not boil.
15 days in the refrigerator maximum.
Gesso preparation :
In 1 liter of warm Rabbit Skin Glue, add up to 1 kg of Whiting powder.
Traditional Gesso is perfect to use on bad condition woodwork and furniture.
Apply a thin coat of neutral skin glue or colorless fish glue. Once dry, apply using a paintbrush the traditional Gesso using as many coats necessary, let dry for 2 hours. Then sand down using a 220 grit paper to even the surface.
