Have been doing some reskimming in a colleagues house she has is now doing up. Old terrace, bay window. On one of the lower bay walls was a damp area, just over a foot square, maybe more. I did take it back to brickwork and used hardwall prior to multi. That was a few months back. Apparently the damp has re-appeared. She has been trying to dry the room out since that time. I'm not sure really what to do at the moment, should I buy one of those damp metre gadgets? At what point would it be dry enough to re-attempt the job?
Also I need to repoint a few mortar joints near ground level on another job, what is the right mix for this? Thanks in advance.
