damp plaster board

[waltram]

Had leak in roof after weeks of heavy rain, now in process of being fixed. The Rain has ran down between plaster board and no fines concrete wall on outside wall from bedroom to living room.
There is slight smell in living room and wall feels cold.
Will plaster board dry out in couple of weeks just with heating on,.
or do I have to do anything.
Thanks

ventilation is better for drying than heat is, so open the windows.

If you have any domestic fans, set them to blow on the damp wall. You don't need fan heaters. The air movement will help water to evaporate off, so it can ventilate out through the windows. It will also cool the damp wall, which will slow growth of mould or fungus. Warm moist conditions are very prone to growth.
