1000+ questions about gold, silver, and metal leaf; gilding supplies, tools, techniques; edibles; craftwork; and troubleshooting.
Apply gold leaf by preparing the surface, applying the correct size, waiting for proper tack, laying the leaf or foil, brushing excess, and sealing only when needed.
Gold leaf can be applied to metal after the metal is cleaned, degreased, stabilized, and properly primed or sized.
Metal surfaces often carry oil, oxidation, polish residue, corrosion, or coatings that interfere with adhesion. Remove contamination and use a compatible primer or size system before leafing.
For exterior metal signs or architectural details, use materials suited to weather exposure. The leaf, size, primer, surface preparation, and drainage/abrasion conditions all affect longevity.
The surface determines the gilding system. Wood, frames, furniture, glass, walls, ceilings, metal, paper, leather, and exterior signs need different preparation, size, leaf, and protection.
Start by identifying surface and exposure, then clean and stabilize the substrate, smooth/seal/prime or ground as needed, choose the right leaf and format, apply the correct size, wait for tack, lay leaf, brush, burnish if appropriate, and seal only when required.
Wood is porous; frames may need gesso, bole, or water gilding; furniture needs wear planning; glass may require reverse-glass technique; metal needs cleaning/degreasing; walls and ceilings need coverage and access planning.
