Wheat Paste

Wheat Paste

Definition

Wheat Paste is a traditional, reversible, pH-neutral adhesive made by mixing refined wheat starch with water and heating it until it forms a smooth gel. It is favored in conservation framing for its strength, compatibility with delicate materials, and full reversibility when moistened.

Uses in Picture Framing

• Primarily used to create archival-quality hinges for attaching artwork to mounting boards.
• Often paired with rice paper or mulberry paper to form S-hinges, T-hinges, and V-hinges for delicate artworks such as prints, etchings, and watercolors.
• Preferred for museum and conservation applications due to its reversibility and minimal impact on original artwork.

Advantages

• Reversible - can be safely reactivated with moisture for removal.
• pH-neutral and archival, making it safe for long-term display of valuable works.
• Compatible with natural fibers like Japanese papers, which absorb and bond effectively.

Application Tips

• Apply thinly with a soft brush to prevent warping or cockling of paper hinges.
• Allow paste to cool and fully hydrate before use for optimal consistency.
• Store refrigerated and discard if mold develops.
