Hi, I have some large flags outside my house - old yorkshire ones I guess. A triangular piece about 6inch by 6 inch has been broken off one edge about an inch deep - not all the way through the flag. I don't want someone to fall but I'm too tight to replace the whole thing.
I have now tried to "fill" this with cement, cement and sand, patch repair - and so on. It just drops out after a few days.
anybody got any ideas.
