WHERE TO USE
Water-repellent and colourless surface treatment for cementitious renders, cellular concrete, facing bricks, natural and artificial stone against heavy rain. Some application examples:
▪ Repair of plastered walls exposed to rain.
▪ Colourless water-repellent protection of period buildings or those of special architectural value.
▪ Water-repellent treatment for walls and natural stone.
Antipluviol is a colourless liquid based on silicon compounds in water ideal for impregnating all absorbent mineral materials used in building. Applied to a porous surface, Antipluviol penetrates deeply and reacts with natural humidity to form a water-repellent layer inside pores and capillaries. Thanks to this property, Antipluviol forms an efficient barrier against aggressive agents present in the atmosphere, which are carried into the material by rainwater. Antipluviol does not form a film on the surface, therefore the material’s permeability to water vapour is not modified and the appearance of the surface remains practically unaltered. Antipluviol has excellent resistance to the alkalinity present in cement materials and to ultraviolet rays.
Impregnation with Antipluviol is unsuitable for waterproofing: ▪ horizontal surfaces (terraces); ▪ basements; ▪ water tanks; ▪ walls subject to rising damp carrying salts; ▪ lift wells and areas subject to water under pressure; ▪ gypsum surfaces; ▪ synthetic plasters and surfaces decorated with synthetic paint. Carry out a preliminary test to ensure no colour changes take place on the substrate when Antipluviol is to be used on natural stones, coloured renders or on other types of substrates which show no uniform absorbency.
