Abstract

This paper deals with the study of the facade elements of the parish of San Pablo in Seville (1961). They are made with polymer mortar. A characterization of the coating plates was carried out and possible solutions for recovering the altered material were analyzed in order to facilitate a future intervention. The resins used as a binder were identified as aliphatic polyester. The resin study was carried out to assure the compatibility of restoration products. Materials characterization provides information about the structural capacity of the plates and the properties achieved. The plates’ colorimetric control is an inexcusable necessity, since any action on the surface of the pieces leads to a color change. All the analyses and testing carried out have led to the creation of an appropriate treatment system for recovery of the plates that provides sufficient information to the intervention project managers to justify decision-making.
