Some years ago we had an existing open porch enclosed. One of the now internal walls (which was external brick) was plastered. Ever since damp from the adjoining outside brickwork has permeated through to the inside blowing the plaster and lifting the paint.
Have tried sealing the brickwork outside with silicone. No good. Have tried sealing internal plaster wall with various waterproofing mediums. No good
Can anyone suggest a way of stopping? Is a vertical dpc possible?
