What is the best treatment to remove moss from a fairly old rough tarmac
surface please?
But if the tarmac is shaded and pitted and holds moisture, the moss
will eventually return whatever you do.
Actually, it will return if it grows there - end of story.
Be warned that caustic soda is EXTREMELY nasty stuff, and breathing
any or getting any in your eyes, mouth or nose will leave you with
damage that A&E cannot fix.
A pressure washer can seriously damage weak tarmac, and ferrous
sulphate can stain any concrete yellow, but those are minor by
comparison.
