One of the causes of degradation of the decorations are produced because of the ascension by capillary moisture. Three rooms on the ground floor of the Royal Palace of la Granja have been intervened by the Dry Kit, TRS114 formulation system and we have really found the capillarity effect has disappeared. Obviously, the damage produced by this rise of humidity in the decorations. Salts that carried water dissolved, leaving abroad increase volume, which leads to a rupture of the plaster and fall decorations and support.
The restoration in the wall paintings in tempera, consisted in the removal of salts, through «dark» of demineralized water; later recovery of the plaster of gypsum, taking profiles and completing volumes and finally restoration of the paint layer to the temple and hatched in fine gold.
The restoration of the marble stucco plaster, has required a particular intervention, since it has been necessary to reproduce with the same technique all the framed stucco that had the lower parts of the room. The technique of execution to match these Jaspers, requires the expertise of the plasterer, which should equal tones and the design of the marble playing. This technique consists in use: plaster, animal glue, mineral pigments and a little lime. These elements together and working skillfully manage to recreate Marbles that can exist in nature or that are pure fantasy. The problem lies in matching tones and designs of others, for mimetizarlos in the whole.
Another of the elements to restore, have been the filigrees of stucco volume in the mouths of doors and balconies of the Palace. These watermarks are very representative of Baroque decorations, van made of plaster using a run-on dies, which sit spot and then Brown in fine gold to the armhole.
