How to restore and dehumidify masonry.

NOVOMUR^® has an open cell honeycomb structure. Cavities are surrounded by a thermal insulating skeleton which keeps them spaced and protects their internal surfaces. The alveoli communicate with each other through a dense network of micropores which ensure, by suction, the transport of humidity towards the larger alveoli, from which it then evaporates.
Then there is a depressurizing effect, due to the fact that a very high quantity of air in contact with the outside air is created in the plaster’s thickness. There is a formation of microvortices, which inhale steam and make the material dry even in the presence of a continuous humidification process. This occurs in the case of walls against the ground or with foundations immersed in water and in the case of widespread water infiltrations.

By applying NOVOMUR^® depressurizing plaster, on both sides of a damp wall, the humidity incorporated throughout the thickness moves, in a continuous flow, towards the hot sides. There it is inhaled and expelled, in the form of vapour, by the depressurizing thermal mass, until completely exhausted. The continuous dehumidification process thus stabilizes at the base of the wall, preventing both humidity and salt formation; in this way the masonry is no longer wetted by dispersed water and much less flaked by salts.
