Conservation image Maya Initiative (1999–2009)
A project of the Getty Conservation Institute

Surface treatments can be divided into three main operations: general cleaning, removal/reduction of previous interventions, and stabilization. Each requires a different set of materials and equipment. Reduction/removal of previous treatments carried out on the Stairway using acrylic or polyvinyl acetate (PVAc)-based resins requires chemical solvents. Some solvents, including acetone and distilled water, are found locally in pharmacies and hardware stores, although other basic solvents such as toluene are not available for retail purchase in western Honduras, but can be found from wholesalers in San Pedro Sula. All basic tools and materials for removal/reduction of previous treatments (scalpels, brushes, cotton swabs, etc.) can be found in San Pedro Sula. Photo: Richard Ross.
