1000+ questions about gold, silver, and metal leaf; gilding supplies, tools, techniques; edibles; craftwork; and troubleshooting.
Gold foil paper can mean decorative foil, edible foil, craft foil, or genuine leaf. The correct product depends on the intended use.
Use gold foil paper by matching the material and format to the surface, then applying it with the correct size, tack, and finishing method.
Apply foil using the method intended for that foil: craft transfer, hot glass, edible placement, or decorative adhesive. Do not assume it applies like loose gold leaf.
Prepare the surface first, then apply the compatible adhesive or size and wait for the right tack. Lay the material with slight overlap, patch misses, brush excess gently, and seal only when the material and exposure require protection.
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.
