AESTHETICS AND DURABILITY
Aesthetic qualities along with high mechanical performance properties and durability were the criteria which inspired this restoration project. The choices made during the design phase and when carrying out the various interventions also took into account the repair work required on the historic features of the palace.
The first operation was to apply SILANCOLOR CLEANER PLUS, a hygienising treatment in watery solution resistant to mould and algae, to carry out a deep-clean of the substrates. All the detached areas of masonry that had been removed during the cleaning operations were reintegrated with MAPEWALL RENDER & STRENGTHEN high strength, fibre-reinforced, natural, hydraulic, lime-based, transpirant mortar with very low emission of VOC (Volatile Organic Compounds).
Once the restoration work on the façade had been completed, the entire surface was consolidated with SILEXCOLOR BASE COAT, a special modified potassium silicate-based, highly transpirant coloured silicate undercoat. This product helps improving the final bond of potassium silicate-based finishing products, when applied on old, organic resin-based finishing materials. This part of the work also served to prepare a base for the skim coat to be applied later, which was carried out using MAPE-ANTIQUE FC GROSSO, a coarse-textured, large-grained, salt-resistant, lime and Eco-Pozzolan-based, cement-free breathable mortar specifically developed for use as finish of de-humidifying, transpirant or "structural" renders when repairing stone, brick, tuff and mixed masonry, including on buildings of historic and cultural interest.
The next step was to apply a coat of SILANCOLOR BASE COAT, a water-repellent, coloured silicone resin-based based paint in water dispersion, and the finishing operations were then completed by applying a coat of SILANCOLOR PAINT PLUS, a water-repellent, transpirant siloxane paint for the hygiene of interior and exterior walls. It protects surfaces from the action of algae, mould and fungi, forming a long-lasting protective coat on the substrate.
