When there is a wall affected by rising damp and characterized by the absence of salt efflorescences, Diasen system provides for the use of the dehumidifying plaster Diathonite Deumix, a product based on natural hydraulic lime, highly breathable, with an excellent μ value equal  to 4.

This plaster, thanks to the presence of macropores, allows to obtain an excellent hygrometric exchange with the environment, avoiding the formation of efflorescence and the erosion of the masonry. The dehumidifying action is helped by the good thermal performance of Diathonite Deumix (λ=0.080 W/m°K). Effectively eliminating the moisture due to hygrometric problems, it is possible to avoid the formation of condensation, the main cause of molds and unsafe environments.

This is the only system that combines in a single operation capabilities of sanitation and dehumidifying with the high thermal insulation capacity, thus creating a genuine system of rehabilitation and energy efficiency upgrading. Consequently, the system ensures consistency and continuity of insulation, because the humidity will be continuously discarded and the insulating layer will remain dry.

To complete the system it is applied the smoothing finishing Argacem Neutro, if applied indoor, or Argacem HP, if applied outdoor, over which it is possible to apply the fixative D20 and the breathable and water repellent Plasterpaint coloured.


  • Dehumidifying system: the system is able to solve the main problems related to rising damp
  • Fire resistant: Euroclass A2
  • High dehumidifying and hygrometric power: the system is able to absorb and release up to 1 l/sqm, and thanks to its high breathability it is able to balance the hygrometric equilibrium of the rooms
  • Eco-friendly and natural system
  • It does not need high thicknesses: the system adapts itself perfectly to the surface to be treated, even if it is irregular, avoiding the formation of air room and reducing the required thickness
  • Very fast application system (application by pump)
  • It combines thermal insulation characteristics with those of dehumidifying, realizing a real consolidation and energy upgrading system
  • System designed specifically for internal application in underground rooms
