1000+ questions about gold, silver, and metal leaf; gilding supplies, tools, techniques; edibles; craftwork; and troubleshooting.
Apply metal 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.
Apply metal leaf by treating it as imitation decorative leaf with its own sealing and handling requirements.
Prepare the surface, apply a compatible size, wait for tack, place the leaf with slight overlap, and brush away excess after it bonds. Metal leaf is often easier to handle than loose genuine gold, but it can still wrinkle, tear, or show surface defects.
Most metal leaf is intended for indoor decorative use and usually needs sealing to reduce tarnish or discoloration. Avoid fingerprints before sealing, especially on copper-alloy and variegated leaf.
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.
