A new method of treating various textiles, for which sewing is unsuitable, is described. Using a mixture of polylvinyl acetate) resins AYAA and AYAC as a heat-seal adhesive, the textile is mounted onto a supporting fabric. The preparation of the adhesive coated support is carried out using a spray gun. The treatment of a badly deteriorated 19th century silk American flag is described in detail. Steps include flattening, heat-sealing to a support, and final mounting inside a protective enclosure. Two variations in the use of poly(vinyl acetate) resins as a heat-seal adhesive are given. These involve the mounting of a painted Chinese silk and a printed silk square by Matisse. The physical flexibility achieved by spray application, the excellent aging and handling qualities of the resins used, and the safety provided by the final mounting package are discussed.
