REABILITA CAL AC is a dry mortar formulated exclusively from natural hydraulic lime, intended for the execution of finishes with excellent vapor permeability, in renovation and rehabilitation solutions of old coatings. It incorporates carefully selected silicon and limestone aggregates and additions, with particular properties of thixotropy, vapor permeability and durability particularly adapted to the use in coating rehabilitation systems.
Finishing layer solution, with thin thickness and fine sanded finish, for subsequent painting, indoors and outdoors. Available in Natural, White, Sand, Yellow, Roasted Yellow, Pink, Old Pink, Salmon, Brick, Blue, Dark Blue, Mint, Light Grey and Grey. Its grain size is < 1.0 mm, the theoretical consumption of 1.20kg/m²/mm, with a compressive strength of Class CS II, an adhesion to brick and block of 0.2 MPa/B, modulus of elasticity 1750-2250 N/mm2, volume of 150 kg/m³, a capillarity(24h) of 0.3 kg/m², a permeability to the water value of μ 15, reaction to fire class A1 and a thermal conductivity of 0.45 W/(m.K) (P=50%).
The REABILITA CAL AC is used as a finish in the conservation and rehabilitation of the building, especially when it is intended to recover exterior coatings of facades of old buildings, which require high levels of water vapor permeability. REABILITA CAL AC is a thin plaster that allows the obtaining of fine aerated finish on replacement plasters of type REABILITA CAL RB or on mortars for treatments of ascending humidity and saltpeter, such as REABILITA CAL MP.
The REABILITA CAL AC can also be used on old plasters, provided they have adequate physical and mechanical conditions of conservation.
