Dehumidifying plaster
A lightened plaster based on hydraulic binding agents with low soluble salt contents. Thanks to it macro-porous structure it greatly increases the evaporation speed of water because it increases the specific surface of the wall. It acts like a pump which sucks water from the walls and it eliminates it by evaporation in the atmosphere.
How to apply:
 |
1. Deplaster the wall at least 1 meter higher than the maximum capillary rise and get rid of crumbly parts (sandblasting). In case of mixed masonry, apply a raw floated levelling off scratch coat with cement mortar and AERMIDE, an additive which acts as anti-salt agent, especially for well soluble salts like nitrates and nitrites present for example in barns. To prepare the levelling off scratch coat you need: |
 |
2. In case of walls with a regular surface like a brick wall, apply RESISEAL directly on the salt barrier. If you notice any really soluble salts like nitrates, first apply a splatter with mortar and then AERMIDE, prepared as per previous instructions. |
 |
3. Apply RESIMIDE dehumidifying macro-porous plaster. It must be prepared in a cement mixer by adding water in the following ratio:
RESIMIDE + WATER = 100 + 30 |
 |
4. Apply a plaster finish with thin surface smoothing. The product, which should preferably be lime-based, must preserve the transpiration capacity of RESIMIDE. |
