Helping a friend renovate a flat I have found some damp- probably rising damp- so put a hygrometer in the room. It typically reads about 70%. But living in the west of Scotland it is usually more than that outside. Information on the internet suggests a room should be about 50% but I have always understood that a well ventilated room shouldn't have damp issues and if the humidity outside is 70% then 70% is as ventilated as you can get!
Obviously I am missing something here but am very confused.
Could someone point me to some good info on the subject?
