Restore the walls from humidity and the damage that derives from it, means safeguarding the environment in which we live, in this sense the interventions acquire considerable importance. Before starting any type of intervention on the walls, it is good to ascertain the nature of the phenomena that generate humidity and the amount of it contained in the walls, since the intervention methods depend on the type of humidity present. Then you can move on to the choice of dehumidification systems, which must be weighted on the basis of the analyzes detected. To make an idehumidifying plaster usually specific macroporous products with high evaporation are applied.
They can thus be realized dehumidifying plasters with pozzolan, lime, cement, mixed, etc. together with inert earthenware type, quarry sands, river sands, ground stones, quartz sands, cereals, etc.
Through the application of the special macroporous plaster with high breathability, it is possible to create a sort of internal circulation of air, allowing the evaporation of moisture. Therefore, thanks todehumidifying plaster, the wall will keep dry. This happens because the evaporation mechanism, created by the pores inside the plaster, is twenty times greater than a normal cement plaster. Therefore the plaster will be able to evaporate the moisture at a faster rate than the humidification rate.
L'dehumidifying plaster it is a natural and economical system with no contraindications and can always be used, even in combination with other systems, it is also easy to use and, thanks to the different categories, it allows you to choose the most suitable solution for the type of problem to be solved.
For the application ofdehumidifying plaster it is sufficient to cover a minimum layer of 2 cm. It can be done by hand with a trowel or by machine with common plastering machines following the normal instructions for applying the plaster.
The plastered walls to be restored are almost always in poor condition and require the removal of the plaster. Given that it will still be necessary to intervene with the reconstruction of the plaster, the incidence between a normal plaster and a dehumidifying plaster, becomes negligible.
