As above, I have treated our small deck with anti-moss and slime stuff. It says to make sure it does not look to rain in the next few hours when you apply it, which I managed to arrange with the man upstairs.
We have some deck stain to paint on, which will hopefully protect the deck. Do I need to wait for the moss killer to do its stuff for a few days. Am happy to wait because it gets me out of a job today, but the wife is worried we will never get round to it if we don't do it today, especially as we have all the stuff out of the way.
