First, the water from the highest elevations of the walls to which it has climbed slowly begins to move towards the lower parts.
- In the initial phase of the system, when the moisture inside the walls starts, increased evaporation of moisture into the room can occur, which causes increased air humidity. This change in dehydration indicators may be visible on the building, but not necessarily. Because of this phenomenon, it is necessary to ensure good ventilation of the space, which is important in the dehydration process, at least in the first weeks of system operation.
- During the dehydration process, the surface parts of the walls are dried first. Thus, damaged materials (paint and plaster) increasingly peel and fall off. It is also one of the indicators of changes that occur due to dehydration of the structure.
As a result of the dehydration process, materials often change color (become lighter) and smoother to the touch.
