In addition to controlling humidity, what else should a restorer manage to increase the rate...

The IICRC WRT body of knowledge identifiessurface temperature of affected materialsas a critical variable influencing the rate of evaporation. Evaporation increases as surface temperature rises, provided the surrounding air has a lower vapor pressure than the material.

The WRT manual explains that increasing surface temperature raises vapor pressure within wet materials, enhancing the vapor pressure differential that drives moisture into the air. This is why controlled heat, airflow, and dehumidification must be managed together.

While outdoor temperatures and dehumidifier coil temperatures may affect system performance, they are indirect factors. Occupant count is not relevant to evaporation physics.

Restorers are trained to monitor material surface temperatures using infrared thermometers and to adjust drying systems accordingly. Managing surface temperature—without exceeding safe limits—supports faster, more efficient drying and reduces overall restoration time.
