It is coloured mineral thick-layered coating, in paste ready to use, conceived for the finishing, decoration and protection of interior and exterior facades.
It is composed of selected aggregates, inorganic pigments and specific admixtures, all bound with specific resins and potassium-silicate.
It is a transpiring product, resistant to chemical and atmospheric agents, moulds, algae and fungus attacks, low and high temperatures, excellent stability over time.
Thanks to its look and its potassium-silicate composition, it has got a suitable adhesion on cementitious base substrates, old and new buildings, on lime base plasters, on cementitious skim coats; in case of renovations it is suggested to remove any eventual synthetic coating before the application.
Substrates conditions and their preparation are at the base of a good result for the coloured coating (not referring to application’s performance quality). Substrates may be in cementitious base or lime; then they must be solid, dry and perfectly cured (28 days); No grease traces, dust, humidity rejection, saltpetre, and anything could compromise a good bonding.
To prevent mould developments and bacterial attacks, before the product application, it is necessary to treat the surfaces with PREVEN R50.
In case of restoration, before the application it is recommended to remove eventual old damaged coatings, restoring with cementitious mortar or skim coat at low thickness, and let cure all the adjustements effectuated before the application. Before the application product, substrates have to be treated, 24 hours before and for the entire surface, with adapted fixative PRIMAR SIL in silicate-resins base, through roller or brush for a better workability, bonding and compactness of the final coating.
The product is in paste ready to use, already coloured, to mix accurately before the usage, by means of drill at a low speed rotations, until you obtain a dough homogeneous.
The application is to effectuate in two coats, on fine substrates perfectly planar, through a first coat application to smooth with inox trowel and then apply a second coat, after almost 24 hours, finishing it with plastic trowel in circulating movements to obtain the desired effect.
