The purpose of these interventions is to reduce the decay caused by atmospheric agents on stone and brick surfaces.
It’s very important for the product to maintain surface breathability: the material to be treated always contains a certain amount of damp which in certain weather conditions, e.g. sun and heat, tries to come out: a film and non-breathable coating doesn’t prevent damp from being pulled towards outdoors but it blocks it from leaking. The risk is the detachment of the surface layer with both support and coating.
SILOXIL 500 water-repellent does not form surface films and does not change the esthetical appearance of the surface: the active ingredient inside makes sure the drop flows away without impregnating the support.
