Shellac is used both to seal porous surfaces prior to size application and to give shine and light protection to gilded finishes. Once dry it gives a warm tone to the surface.
Natural, organic resin in irregular orange brown coloured flakes.
Soak shellac flakes in an at least 95% ethanol solution. After 24 hours the shellac will have been totally absorbed. Filter the mixture to remove any deposits and impurities which may have formed. The shellac will be ready to use. The resulting shellac and alcohol solution can be stored for several months if stored in a carefully closed container. Filtering before each new use is recommended.
Approx. 250 g of shellac per litre of alcohol.
Store in a cool, dry place in its own container, closed, and away from direct light and heat. The ideal temperature is 15-20°C with humidity under 50%. The product is not cold sensitive but can be damaged by heat.
Dilution percentage, application method and quantities applied may significantly affect the workability time. The most suitable application methods should be determined by experimentation on the basis of the surface being gilded and the desired result.
