Diathonite Deumix is ​​a completely natural dehumidifying plaster, as it is cementless, formulated with pure NHL 5 natural hydraulic lime, cork, clay and diatomaceous powders. Diathonite Deumix is ​​used for dehumidification and restoration work on all walls affected by capillary rising damp.

In addition to the high dehumidifying capacity, this product is characterized by the excellent thermal insulation power, which allows to limit the formation of interstitial condensation and therefore the amount of moisture to be disposed.
