Renovation of external façades

It is an exhibition museum located in a Villa of the 1930s, surrounded by green, in the center of Varese, completely restored.


Façades and buildings in decorative cement

  • Removal of ivy vines from the surface before proceeding with renovation.
    Renovation works through sandblasting and water jet cleaning: cleaning of surfaces with an appropriate sand-blasting system through a product called GMA GARNET (completely natural mineral abrasive, chemically inert and free of any toxic metal, silicon or ferrite) with low pressure portable machines. This system, used to clean the most delicate
    surfaces, does not affect the support and prepares the surfaces for the subsequent finishing treatment.
    Successively the water jet cleaning phase was performed, using atomised pressurised water (from 50 to 200 atm), to then apply the specific conservative product.
    For buildings in decorative cement – eaves, parapets with bannisters and stone skirting, a water repellent conservation product was applied.
    Control of plaster stability, removal of damaged areas and execution of repairs.

Painting, beginning with a first coat of consolidating fixative

  • Façade smoothing
    Application of a first layer of a lime stucco using stainless steel trowels, reinforced with ETA-certified network of fibreglass with an anti-alkaline band ‘160 netting’ weighing 160 grams per m2, warp knitted, overlapping the frames by at least 10 cm.
    24 hours after the first coat, a second layer of lime stucco is applied.
    24 hours after the second coat, a third layer of finishing lime stucco is applied.
  • Façade painting
    Painting with a first coat of high penetrating potassium silicate-based mineral fixative for plaster for all surfaces.
    Painting with a first coat of potassium silicate-based water repellent mineral paint applied by brush for all surfaces.
    Painting with a second coat of potassium silicate-based water repellent mineral paint applied by brush for all surfaces.

Parapets and gratings

  • Scraping of remaining peeling paint and manual sanding of all surfaces
  • Application of anti-rust base coat – iron oxide – on all previously prepared surfaces
  • Varnishing with double coat of synthetic micaceous iron enamel

Museum Exhibition Halls

  • Application of emulsified acrylic resin-based inhibiting sealant (transparent or coloured)
  • Two-stage painting in light solid colour with emulsified water based-vinyl resin paints – on two-coat plaster or smoothed stucco internal surfaces

REQUIREMENT – condition of the building:

The façades present a deteriorated state caused by erosion due to atmospheric agents, and the fact that the building was in disuse for years – in fact, the surfaces are largely covered by ivy and other vegetation.
After some structural modifications performed by the Client, we were requested to completely renovate the building.


After inspection and viewing of the state of the surfaces requiring repair, an intervention of renovation of the external façades was established.
For interior works – museum exhibition halls – painting with water-based paints was envisaged.
For iron works – parapets and grating – cycles of varnishing with micaceous enamel were identified.
