Ive borrowed someone pressure washer to attempt to clear the weeds from my back garden paving, but i also might try using it on the monoblock drive at the front, is there anything i should be aware of before i start this, ie will i need to brush in new sand once finished as i get the feeling that its just going to blow out whats there.
also whats the best way to go about pressure washing decking, the whole decking needs cleaned and treated as it in a bit of a mess but not that old i dont think (was there when we moved in a year ago)
cheers
