I have used this on our long gravel drive and find that the weed killer works well. It normally take a few days to work after application but it is worth the wait.

The best
A lot better value than buying the ready to use roundup that has gone up in price massively at garden centres over the past two years. Takes a few minutes to mix but it would take some time to refill a sprayer with ready mixed anyway. Probably brought my spray cost down from 140 per annum at new ready mix prices to 25 / 30 using this concentrate.
Having jet-washed our patio we wanted to keep the area weedfree. We went for the strongest mix and now, several months later, there is no sign of weeds. So far so good! And, at less than 16.00, we will repeat the treatment regularly.
Does the job perfectly
This weedkiller is fantastic stuff
very good value and price
