High-performance, silicone water-repellent in watery solution for external walls. Colourless surface treatment for cementitious renders, cellular concrete, facing bricks, natural and artificial stone against heavy rain.

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.

Where to use:

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.
