Our research aimed at comparing the performances of some polymeric products used for the protection
of a typical Italian sandstone, the ‘Agro d’Ardesia’, used mostly as cladding, paving, roofing, and building
material. These products belong to three different classes: polysiloxanes, acrylics, and fluoropolymers.
In addition, an acrylic–silicone mixture was chosen for testing. After the application onto the Agro
sandstone by capillary absorption, both efficacy and durability were assessed. Particularly, two types of
weathering tests were performed to check the stability over time of the protective products: the exposure
to ultraviolet radiation in a climatic chamber and the ageing by exposure to acid rain, expressly designed
to represent realistically natural and anthropogenic changes. Detailed information on treatment
performances was obtained. The polysiloxane was shown to be the most effective protective material for
the Agro sandstone
