Allback Pure Shellac Flakes

Allback Pure Shellac Flakes

  • 1000

Pure shellac flakes can be mixed with a few drops of ethanol (pure denatured alcohol) or methanol (methyl hydrate) to create a thick syrup for sealing surfaces. Thick shellac generally only requires one coat.

Shellac is an excellent general barrier. This mixture is commonly used to seal knots in wood to prevent the sap from eventually bleeding through the finished paint. It is also used in glazing to seal the rebates of wooden windows before applying Allback Linseed Oil Putty to prevent the wood from absorbing the oil out of the glazing putty and drying it out prematurely (which is why old glazing always lasted for so long).
