Hi guys, after requiring to remove the hip tiles that meet to an external corner to put up my pergola, iIwould like to re mortar the tiles down.
I used some cement and sand once before but it didn't last long, so before I do these ones, is there a special mix I am supposed to use? do I need to add lime or something.
It kind of looks like my whole roof needs redoing, but at the moment i am only worried about these two corners
