Surface treatments
In order to maintain and protect surfaces against water and, in
general, against the aggression of atmospheric agents.

Water is one of the main causes for structure degradation.
Water is a vehicle for salts which deposit on the external surface and
which are visible as efflorescences, algae, fungi, ect…not easy
to eliminate.
Other than soluble salts, water also transports acid substances which
attack the structure and corrode the surface.
During winter, when the temperature goes below 0°C the water which
is present in the capillaries of mortars, stones and bricks, freezes
increasing its volume to decrease later when the temperature rises.
These cycles of frost and defrost damage the structure year after year.
Finally it’s good to know that when water is absorbed by the structure,
a noticeable decrease in the thermal isolation occurs.
Thus it is important to eliminate both humidity and water, letting the
surface of the structure transpire, in order to protect and maintain
structures with time.
