Once the badly damaged cementitious render had been removed and the surfaces had been carefully cleaned to remove any loose or detached material, a 2 cm layer of MAPE-ANTIQUE STRUTTURALE NHL mortar was applied to level the surfaces, followed by a coat of PRIMER 3296 consolidating primer, diluted 1:1 with water, and two coats of MAPE-ANTIQUE ECOLASTIC coating, to form a 2-3 mm thick layer. MAPE-ANTIQUE ECOLASTIC is an elastic coating protecting the surface of rendered masonry (including in listed buildings) from seawater, de-icing salts or soluble salts in general. A base layer was created thereupon using MAPE-ANTIQUE ECO RINZAFFO salt-resistant, natural hydraulic lime and Eco-Pozzolan scratch-coat, an ideal base for dehumidifying, breathable and “structural” renders. The next step was to apply MAPE-ANTIQUE ECO RISANA dehumidifying rendering mortar, followed by two coats of MAPE-ANTIQUE ECO RASANTE CIVILE fine-grained, smoothing and levelling mortar.
The facades were finished off with silicate-based SILEXCOLOR PRIMER and SILEXCOLOR PAINT, an one-component modified potassium-silicate-based paint for internal and external vertical surfaces.
The same finishing treatment was also adopted for the internal walls of the building. After removing the existing damaged render and film of paint with power tools, the first step was to treat the surfaces with PRIMER 3296 primer before smoothing over with MAPE- ANTIQUE ECO RASANTE CIVILE.
The facades were finished off with silicate-based SILEXCOLOR PRIMER and SILEXCOLOR PAINT paint.
The exposed beams of the timber roof truss were consolidated and strengthened by treating the surfaces with MAPEWOOD PRIMER 100 and applying MAPEWOOD PASTE 140, a thixotropic epoxy adhesive for restoring timber structural elements, and then MAPEWOOD GEL 120 epoxy-based adhesive, this time in the form of gel.
The last step was to provide protection for the facades, which was guaranteed by applying ANTIPLUVIOL, a colourless, water-repellent impregnator treatment made from silicon compounds in water solution, which forms an efficient barrier against aggressive agents present in the atmosphere, which are carried into the material by rainwater.
