REABILITA CAL AC is a dry mortar, exclusively formulated from Natural Hydraulic Lime, intended for the execution of
finishes with excellent permeability to water vapour in renovation and rehabilitation solutions of old coatings.
It incorporates carefully selected siliceous and calcareous aggregates and additions, having particular properties of
thixotropy, vapour permeability, and durability particularly adapted to be used in coating rehabilitation systems.
REABILITA CAL AC is used as a finish in the maintenance and rehabilitation of buildings, namely when external coatings
of old building facades are intended to be recovered, that require high levels of water vapour permeability. The
exclusive use of the Natural Hydraulic Lime binder and its special composition results in an excellent physical-chemical
behaviour and mechanical performance in connection with the diverse materials constituting this type of substrates.
REABILITA CAL AC is also an integral part of the ETICS system, ISOVIT CORK, an external thermal insulation composite
system based on natural hydraulic lime and cork panels with an ETA. It may also be applied to other coating systems,
namely ECOCORK RENDER and ECOCORK LIME.
