Why We Use Starch Paste in Conservation Framing

Wheat starch paste is a trusted conservation adhesive widely used for hinging and mounting valuable and delicate artworks, including original works, limited editions, and older or fragile pieces.

Hinging

When attaching artwork to a mat, we use wheat starch paste in combination with Japanese mulberry paper—an acid-free material that creates a strong yet fully reversible bond. This method keeps the artwork securely in place while allowing the hinges to release if the frame is dropped, helping to protect the artwork from damage.

Mounting

Wheat starch paste is an excellent choice whenever a reversible bond is required. For valuable pieces, we pair it with museum-quality 8-ply rag board, a cotton-based mounting board that will not degrade or release harmful chemicals over time. Being acid-free, it will not yellow or cause deterioration in the way some adhesives and lower-grade materials can.

Flexibilty

Because all paper naturally expands and contracts in response to changes in temperature and humidity, flexibility is essential. Wheat starch paste remains flexible after drying, allowing it to move with the paper and helping to prevent warping, buckling, or tearing of the artwork.
