REABILITA Cal AC Fino is used as finishing topcoat plaster in building conservation and repair to achieve a very fine finish. It can be used on the interior or exterior coatings of old buildings, which require high levels of water vapour permeability. The use of the Natural Hydraulic Lime binder and its special composition results in an excellent physical and chemical behavior and mechanical performance in binding with the various materials constituting this kind of substrate. REABILITA Cal AC Fino represents the fine finishing stage of the REABILITA CAL rehabilitation scheme, with products exclusively formulated from Natural Hydraulic Lime.
