Any good for patios and driveways or is it useless? At 30p a kilo from
Tesco for the value stuff it's a damn sight cheaper than anything else I
can find. I used to use sodium chlorate when you could still buy it
although the weeds always came back next year.

Failing that what's the best way to deal with weeds in A) block paviour
patio and B) gravel covered driveway?

It should kill any weeds if the solution is strong enough by way of reverse
osmosis.
