IDROALL is a bright silver coloured protective coating, with an innovative formula which is completely eco-friendly and non-flammable. These characteristics make IDROALL easy to store even in large quantities and also, being non-toxic and non-harmful, users are exempt from quarterly visits. IDROALL can be applied on any type of dry surface, but its ideal use is as a protective coating of prefabricated bituminous membranes on which it produces a smooth and streak free silver coloured film. The film made with IDROALL is sufficiently elastic to be able to support the «movements» of the bituminous membrane on which it is applied reducing the great aesthetic problem of «craquelé» (cracking).
