Licata Idrosil Exterior Mineral Micro-Coating

Idrosil Exterior is indicated for the decoration of new or existing external surfaces on residential, industrial or commercial buildings | It is recommended for use on cured substrates, i.e. after a curing time of at least four weeks. | It is applicable on substrates such as: lime-based residential finishing | cementitious-based residential finishing | gypsum (after application of primer in case of very low absorption smoothing | already painted surfaces | after careful checking and cleaning of the substrate | concrete.


  • Mineral: the composition with a base of inorganic binders makes Idrosil Exterior an odourless mineral paint; it is ideal for those looking for natural products for the painting of exteriors using mineral cycles.
  • Versatility: thanks to the fine grading curve < 100 micron. Idrosil Exterior can be applied both manually (brush/roller), and mechanically (airless).
  • Very high breathability: the careful selection of raw materials, united with the typical properties of the silicate, give the paint excellent  values of water vapour permeability.
  • Optimal adhesion strength: the composition with a base of pure silicates gives Idrosil Exterior excellent adhesion properties since it chemically reacts with the mineral substrate by means of a natural process called silicatisation.
