Dehumidifying mortar based on natural hydraulic lime for green building and historical renovation of masonry subject to rising damp, mould, salt efflorescence

it is used for

  • Renovation of damp and damaged walls
  • Green Building
  • Historical renovation


SEYBIO risanante complies with the requirements of the UNI EN 998-1 standard.

Mixed with the correct amount of water, it gives rise to a plastic mortar that is easy to apply. Once it has hardened, SEYBIO risanante achieves good mechanical resistance and is resistant to washout and frost. SEYBIO risanante is to be used in green building and historical renovation as a renovating plaster on vertical surfaces of new or old construction where there is rising damp. This type of humidity is recognizable by its position: it starts from the ground and generally rises up to one or two meters making the plaster darker and forming a line above which the plaster is lighter and therefore dry. Rising damp is typically found in above-ground masonry made of porous materials (e.g. solid bricks).
