What sealer works with gold leaf?

Sealer choice for gold leaf depends on the material, surface, exposure, and desired finish. Silver and imitation/metal leaf often need protection.

The right sealer for gold leaf depends on karat, exposure, handling, and whether the leaf is genuine or imitation.

High-karat genuine gold often does not need the same tarnish protection as silver or imitation metal leaf, but a handled or exposed surface may still need protection. Lower-karat alloys, silver, copper, composition leaf, Dutch gold, and metal leaf are more likely to discolor or tarnish.

Choose sealer only after identifying the material and environment. A wall, frame, exterior sign, furniture piece, and craft object have different abrasion, moisture, and appearance requirements.

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.
