Tests began to recover surfaces covered with vitreous mosaic at the UCV

The Presidential Commission for the Recovery of the UCV carries out tests of materials for the restoration of the glass mosaics found on the facades and internal parts of the buildings of the University City of Caracas, the entity reported in a press release.

To begin the execution of the pilot plan, this Wednesday in the auditorium of the Dean of Medicine, a theoretical-practical workshop was held on the installation and improvements of mosaic tiles, where representatives of the Preservation and Development Council (Copred) of the UCV, Dean's Office participated. of Engineering, Faculty of Architecture, Geology Laboratory, Rock Laboratory, advisors and inspectors of the Presidential Commission, as well as personnel from the companies that carry out the work at the university.

During the day, the presentation of the company Mapei was made, which for 87 years has been offering construction materials such as mortar, coatings or adhesives and presented the proposal for glass mosaics for the development of the recovery project for the university buildings that have with this material.

Architect Dulce Medina explained that for a year the Presidential Commission has been carrying out studies in conjunction with the UCV to determine what materials they should use and how to place the glass mosaics to intervene appropriately and comply with the parameters established to preserve the work of master Carlos Raul Villanueva.

He specified that approximately 50% of the facades and 80% of the internal spaces of the University City buildings have glass mosaic and for this reason these places are still waiting for the start of recovery work.

These small pieces of colored glass are a characteristic element of mid-20th century architecture, due to their durability, quality, variety and little need for maintenance. This material can be seen at the UCV in spaces such as the Central Library and the Dean of Medicine, among many others.

Studio space

The façade of the Deanery of Medicine was the space selected by the Presidential Commission for the Recovery of the UCV, in coordination with specialists from the university and the Mapei company, to begin the test route for the replacement of materials.

Engineer Alfonso Olivares explained that the place was chosen for the test plan due to its location, since there is direct sunlight, and due to the deterioration of the external area of ​​the building located near the University Clinical Hospital.

He specified that to begin testing the Mapei company's mosaics, two spaces were prepared on the façade of the deanery. In one area, a new frieze similar to those currently being used was made with relatively clean material and acrylic adherent, while in another, right next door, the coating was removed and treated with CIPes, a cement grout that consolidates the frieze and offers the possibility of not removing the university's entire friezes, which would save costs.

This Wednesday, Mapei staff carried out the placement and gluing of the coating on the façade. Subsequently, the behavior of the material will be evaluated according to time and the company's recommendation.

The conditions, materials and behavior of the adhesives and the mosaic will be analyzed by the Geology and Rock laboratories, as well as the Institute of Materials and Structural Models, to issue the report on the tests carried out and whether or not the use of this type of vitreous mosaics for the UCV building improvement project.
