1000+ questions about gold, silver, and metal leaf; gilding supplies, tools, techniques; edibles; craftwork; and troubleshooting.
The adhesive for gold leaf is usually gilding size. Choose size by surface, leaf type, exposure, tack time, and finish.
Use gilding size for most gold leaf work; the exact size depends on surface, exposure, and technique.
Oil size is common for architectural, sign, furniture, and general decorative gilding. Water gilding uses a different traditional gesso and bole system and is chosen when a burnishable finish is required.
Do not substitute ordinary craft glue without understanding tack, compatibility, and finish. The size must bond to the prepared surface and hold the leaf at the correct tack window without drowning, wrinkling, or releasing the leaf.

Gold leaf adhesive is called gilding size. The correct size, sealer, bole, and tools depend on surface, leaf type, technique, exposure, and desired finish.
Gilding size is the tacky adhesive layer used to attach gold leaf, silver leaf, palladium, platinum, metal leaf, or foil to a prepared surface. Ordinary glue is not a substitute. Tack timing matters: too wet can drown or smear leaf; too dry can fail to bond.
Silver and imitation/metal leaf often need sealing because tarnish or discoloration is a risk. Tools such as a gilder’s tip, knife, cushion, brushes, mops, burnishers, and pads affect results.
