Análise de massas de reintegração volumétrica para a restauração de faianças do patrimônio edificado.

Abstract

Pelotas city, RS, has in its eclectic and historicist patrimony a set of decorative pieces of facades, composed by faience works. This collection represented the city and region economic and cultural apogee in the 19th century. The advanced state of degradation of the set of fifteen faience sculptures in the building of Museu Municipal Parque da Baronesa, a site belonging to regional and national cultural heritage, guided the development of the present work, whose aim was to study volumetric reintegration masses to be used in the restorative processes of ceramic objects in faience, which are exposed to inclement weather. After the characterization of the faience masses of the ensemble sculptures, we tested the masses composed of three thermoset polymeric resins based on acrylic, epoxy and polyester, which were tested for artificial accelerated aging, porosity, tensile strength and tensile strength. bending, adhesion and durability. The results showed that the restoration is possible with the use of volumetric reintegration mass made of polyester resin.
