Hi
I am new to the forum , I have looked at some old posts but none really relate to my problem, which is I have a large kitchen wall 3.5 X 2.5m and at one end two thirds of the way up the wall is an old oil boiler flue that goes up to the chiminey to its own pot next to the one from the fireplace.The boiler was removed and relocated and has its own flue not connected to this one or the chimney. I want to now decorate this wall with brim slips, what should/can I do with the hole?
Regards
