SILOXANIC PRESERVATIVE FOR INTERIOR AND EXTERIOR USE

NEPTUNUS

NEPTUNUS is a masonry preservative for exterior and interior walls, based on modified siloxanic polymers and special additives which give the product excellent permeability, together with a high level of water repellency and excellent chemical and outdoor resistance. Unlike traditional water-based paints, NEPTUNUS does not form a film, instead creating a porous covering which adheres perfectly both to mineral surfaces and to old mineral- or synthetic-type paints. Consequently, it represents an innovative alternative solution to mineral products, without the problems encountered when using lime- or silicate-based paints. NEPTUNUS’s formulation was devised in conformity with the Kuenzle theory which establishes that exterior plastering must simultaneously meet the following parameters: Water absorption W<0.5 kg/m2 x h^0.5 Resistance against the diffusion of water vapour Sd<2 product of W x Sd <0.1 NEPTUNUS is suitable for protecting and decorating the walls of buildings of architectural interest, in restoring buildings in historical city centres and at the end of dehumidifying restoration cycles.
