WHAT CAUSES MOULD? Especially in modern, heat-insulated apartments without natural air circulation, regular ventilation is necessary. IDENTIFY THE CAUSES One of the crucial factors for mould growth is moisture. Moisture can, for example, originate from the building (e.g. due to leaks, insufficient water pipe system, thermal bridges) or be caused by the room user himself. Professional on-site measures and a sensible behaviour of how to use and live in rooms must work together to keep living spaces free of mould growth in the long term. The use of mineral, hydroactive building materials, which absorb the moisture at peak loads, can have a supplementary effect. For this reason, mould damages require a detailed assessment of the overall situation, the elimination of the causes and appropriate measures resulting from this. Due to the many different influencing factors and damage situations, there is no standard procedure for the renovation of mould infestation in living spaces. Our proven KEIM Mycal-System provides mineral and capillary-active products for quick-drying, alkaline surfaces for almost any individual situation. MOISTURE SOURCES IN APARTMENTS 6 up to 12 liters water a day in a 4-person household If you forget to air the rooms for two days only, there are at least 12 litres of water in the air. This is a lot of moisture that can condense on the walls of your home.

Free ventilation, i.e. opening the windows, is still of central importance. But correct ventilation must be understood. The most effective ventilation method, cross-ventilation, is not always advisable. The necessary exchange of air is determined by the size of the room, its use and the temperature. Modern ventilation concepts support the ventilation of living space autonomously, sometimes even including heat recovery. In order to control the air humidity and use free ventilation in a targeted manner, the following instructions are recommended: – Use of moisture meters (thermo-hygrometers) – Constant tempering of the individual living zones (bedroom approx. 18°C, living room approx. 19 - 20°C, bathroom approx. 20°C) – No furniture along exterior walls – Use of capillary-active mineral building materials on interior walls and ceilings A healthy room climate creates an atmosphere of well-being. approx. 5 – 10 min. 1 – 2 min. max. 30 – 60 min. Ventilation with wide open windows In order to reduce the humidity in the room, this kind of airing (5 - 10 min.) should be carried out several times a day. Note: Cool cellar rooms should not be ventilated in summer or only in the early morning hours. Cross ventilation Cross-ventilation is particularly effective, but only rooms with comparable humidity and temperature conditions should be cross-ventilated (1 - 2 min.). Note: Never cross-ventilate a warm, damp bathroom with a cool bedroom! Tilted window ventilation In individual cases, this ventilation (max. 30 - 60 min) may also be useful (provided that the tilt angles are suitable). Note: This will cool down the reveals considerably and a lot of heating energy is lost.
