Conventional Drying Methods

Natural drying is the slowest method of drying a building and can be severely affected by the prevailing ambient conditions. It is recommended that doors and windows are kept open to provide natural air circulation which in turn speeds up the drying process. Mould and fungal growth may develop more quickly, particularly if temperatures are above 18°C and if there’s insufficient air circulation.

Convection drying uses heat and ventilation, typically in the form of fan heaters or air movers but may also include use of the building’s own heating or ventilation system. Increasing air movement creates turbulence which in-turn encourages evaporation of moisture. Warm air convection heaters may be used to increase the ambient temperature.

Dehumidification (using desiccant or refrigerant dehumidifiers) is typically the preferred method for “assisted” drying. Doors and windows need to be kept closed. The process works by removing moisture from the air. In so doing the air temperature in the room increases, which in turn promotes evaporation from the building fabric. It’s possible to speed up this process by the introduction of air movers.

Different drying methods are not mutually exclusive. Accepted wisdom is that there isn’t one correct method for all situations. In many cases a combination of methods may be appropriate, depending on a building’s age, construction and level of occupation.
