Surface preparation in gilding is not a preliminary step. It is the foundation. Every layer—primer, gesso, sealer, size—must be perfect. Any weakness in preparation will manifest as adhesion problems, uneven burnishing, or surface defects that no amount of technique can fix.
The process requires layers: wood or substrate must be sealed to prevent moisture migration. Gesso must be applied in multiple thin coats, sanded between coats to achieve a smooth, responsive surface. The gesso must be the right hardness—soft enough to be responsive to the gold, hard enough to support burnishing. Then the surface must be sealed, sized correctly, and brought to the exact moisture level required for application.
Most gilding failures trace back to preparation. The gold did not adhere because the size was applied incorrectly. The surface is uneven because the gesso was not properly sanded. The burnish is dull because the ground was too hard or too soft. Gilders learn that technique matters, but preparation matters more. At NoirGold.Art, preparation is where the work actually happens. The gold is just the final reading of that preparation.
