Can anyone advise me on the best time to apply weed killer when cleaning block paving. I have always looked at each job and if there is moss but no weeds or just a few weeds, I clean first and then spray with weed killer but if there are loads of weeds growing I think it best to spray the whole area with weed killer, then wait a couple of weeks before cleaning with a rotary cleaning head. Just wondered what everyone else does.
Also if appling after cleaning, do you resand first or after weedkiller?
Cheers everyone

You should treat with weedkiller before cleaning as the weedkiller has to penetrate through the leafs to be effective

I spray the weeds when I price the job

i do both,

sodium chlorate (i think)  with watering can 7-14 days before if infested with grass etc,

if no time then after clean before sand and poss after sanding also. as required.
