>Anyone got any tried and tested method of getting rid of moss on brickwork permanently?
I'd have thought that if the conditions are right for moss growing then it will keep on coming back unless you change the environment (reduce shade/reduce humidity etc), so expect to do this every year.
You could try creating a permenantly 'hostile' environment to stop the moss growing back rather than killing it back every year - for example put a strip of copper (slug tape?) or zinc at the top of the wall - minute quantities of the metals will wash over the wall when it rains and could well discourage the moss from growing back.
Just a thought
