During the refurbishment of my house a sitting room wall was chased and a pair of 15mm copper heating pipes were buried in the wall.
The well meaning plumber (me) protected the copper pipes by wrapping them in greasy Denso tape. The pipes were then cemented in and plastered over. Two years later there is a greasy patchy line showing through the wall paper, which kinda spoils the room.
Can I remove a strip of paper and seal the wall with something like 10% PVA in water or an oil based paint, or does it all need to come out which is a much bigger job?
Any advice appreciated - Not so Able.
