Not really immediately: the treatment was applied about a week before attempting to remove the moss with the power broom. The tarmac is not smooth enough to use a shovel edge I've the whole.ofnthe affected area: it catches on small.raised stones and pulls them out.Seems pointless to put down moss killer then immediately try and mechanically remove it. Do one or the other.
You might get some of that off with a long handled square edge shovel, or a floor scraper, the tarmac looks pretty smooth?
