Ths video details removal by the strappo method, in which the overlaying painted surface is first coated with a thin layer of cotton cloth and animal glue. Following is a secondary and sturdier layer of cloth extending beyond the perimeter of the work and the outline of the fresco is incised. The entire surface of the painting and protective cloth are then detached from the subsurface by means of pouncing with a rubber mallet, and the fresco and cloth layer are both carefully removed from its support from the bottom up. A new backing layer is then applied to the exposed reverse of the fresco, called "Bella tini," followed by two additional layers of mortar (one rough and another smooth). The two layers of cloth are known as the "sacrficial" or "sacrificial leg," because they serve only to facilitate future detachments and are hence, reversible. The detached painting is then secured to a rigid support and the protective covering removed with a solution of "hot water spray and decolored ethyl alcohol" – exposing the original painted surface to the gaze of the viewer.
