Unisan

Dry premixed, fibre reinforced, lightened, based on a mixture of carefully selected special aggregates and a mixture of hydraulic binders and additives to improve workability and adhesion. The specific formulation allows to combine, in one product, a porous structure which helps the crystallization of salts, a high vapour diffusion enhancing the evaporation of masonry damp, a strong dehumidifying capacity and good protection from rainwater, all without requiring a prior anti-salt treatment.

GRIGONOVA UNISAN may be applied both by hand and with a plastering machine on interior and exterior walls like brick, block, stone, travertine, etc. It is used in the rehabilitation of masonry attacked by salts or in the presence of outcropping moisture. The application must be made on surfaces free of dust, efflorescence, oils, fats and previously treated simply with GRIGONOVA UNISAN.
