You only have to deal with the weeds in block paving...the root system for moss is nowhere near as deep.
Glyphosate (the active ingredient in many weedkillers including Roundup) needs 24 hr to take effect although signs in the plant itself (initial reddening of he leaf) can take weeks. Spray one day ..wash the next.
Glyphosate works by preventing the plant producing amino acids...so the plant "starves" itself to death.
Because of the way it works it is generally considered to be "safe"
Add fairy liquid to your weed killer mix...you will then use less as it "sticks" to the leaf of the weed.
Flazasulfuron could (if you wish to break the law) be added to your mix, this is a post-emergent residual herbicide ,it works by prevent seeds germinating ...keeping your block paving "weed free" longer.

Thanks Chris I have been booking jobs in two weeks after weed killing that's great I can do the following day😄
-
PA1 & PA6 comes to mind.
-
Anything I can use without pa1 or pa6?
-
Not if you are doing it professionally as I understand the rules :(
-
I personally would wait longer than 24 hours but yes, good advice. PA1 and PA6 are legal requirements you need to apply any pesticide.

Looking at getting these done next coarse down near me is mid November not cheap either!
