RESUMO

This research presents an investigation on the base-lime mortar and Juçara (palm tree Euterpe eudulis) laths which were the materials found in the stucco ceiling of the building, Vila Penteado. The guidelines followed in this study were those set fourth by the Institutions of maintenance for buildings and monuments with historical and artistic value. This building was declared a heritage by CONDEPHAAT – The Council for the Defense of Historical, Artistic, Archeological and Tourist Patrimony of the State of São Paulo and by CONPRESP – The Council for the Preservation of the Historical, Cultural and Environmental Patrimony of Sao Paulo City. A broad set of techniques was used to characterize the composition and the microstructure of the primitive mortar, as well as the condition of the materials. The results of these analyzes were useful in proposing a partial reconstitution of the ceiling. The performance of this proposal was evaluated in laboratory conditions by keeping the specimen in a carbonation chamber for thirty (30) days after application, to accelerate curing. The thermal compatibility and adhesion strength resistance of the primitive and new materials were tested after subjecting them to heating and quenching cycles, and the results were used as indicators of the proposed restoration method´s performance. These results showed that the primitive mortar can remain serviceable for many years as long as the correct intervention technique is employed, and the fragility of the ceiling system is in the supporting laths. This evaluation allowed for the elaboration of a proposal for restoring the ceiling system of the Vila Penteado building.
