- Résumé
- Deteriorated marouflaged murals have been treated by conservators in a variety of ways but little scientific testing on the techniques, their reversibility, and ageing characteristics exists in the current literature. Maintaining intended aesthetic qualities of marouflaged murals during conservation and reattachment requires techniques similar to the original marouflage technique. Thus, there is a need to find adhesives that will remain chemically stable and mechanically reversible when used for re-adhering conserved murals to their original substrates. It is not the intention of this research to find the perfect adhesive but to provide a preliminary investigation into one commercial wallpaper adhesive. Wallpaper adhesives exhibit the characteristics of an effective marouflage adhesive: viscous pastes that apply evenly, have a slow setting time, and a high level of tack. They are accessible, economical and non-toxic, making them very appealing. However as a commercial product, the ingredients are not easily available and their use in conservation often raises a number of questions. What are the ingredients and their ageing characteristics? What are the long-term effects of the adhesive on canvas murals? Will the adhesive remain reversible over time? To address these questions, reattachment of a marouflaged mural was simulated using the wallpaper adhesive, Dynamic® 208 Clear Wailcovering Adhesive, to attach primed linen to a sealed drywall substrate. The concentration of the adhesive, and the addition of interleaving, was varied with the objective of fmding a technique that would achieve ease of reversibility and maintenance of bond strength. Samples were subjected to tensile peel strength testing, FT-W analysis and qualitative reversibility testing. Testing was done before and after thermal accelerated ageing to analyze the material composition, assess mechanical properties, and reversibility. It was hypothesized that diluting the wallpaper adhesive by 5% and 10% with an aqueous solution of methylcellulose might accomplish sustained strength and mechanical reversibility without the need for an interleaving layer, under particular conditions. This could lead to more accurate reattachment techniques for marouflaged murals and help to maintain the intended aesthetic qualities.
