Self-Supporting Methylcellulose Meshes - An Innovative Bonding Tool

A new bonding system for the reinforcement of paintings made on textile supports will be presented. These are self-supporting, flexible meshes produces of a series of pure and well-established conservation adhesives. The main focus will be set on methylcellulose. Technically, the procedure involves positioning of the mesh in dry state, activation with controlled supply of moisture or solvents, and application of pressure to trigger the bonding. This approach enables an exceptionally precise application, thus minimizing the risks related to conventional use of liquid solutions, namely shrinking, stiffening and darkening of textiles. Furthermore, compared to hot-seal adhesives, methylcellulose meshes are particularly suitable for paintings that are sensitive to heat as no elevated temperatures are required for the activation.
