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)

Don't use a fine jet. It will displace any amount of weeds, mortar /
sand, dirt, moss, oil, etc. The problem is, it will do it in a very
localised area (i.e. the area of the jet). Then you're faced with trying
to match that, or blend it elsewhere. Same goes for decking.
Start with a fairly diffuse jet, and work out what your doing, take your
And, yes, you are likely to need to replace sand etc.
Kδrcher do an attachment ("Patio Cleaner" IIRC) that gives a much more

for the health of the operator.
Actually I'm pretty sure it won't get the weeds out of the cracks on the
OP's patio (one of the points is that it *doesn't* lift stuff out of
cracks), but it will be good for the deck. Careful spot application of
the lance (or even a trowel), before the T-Racer, would be the way to go
- Don't underestimate the mess you might make of everything other than your
paving. Mud splattered in all directions at high speed tends to cause a
mess (to yourself and everything around you).
- Do wear googles. You will manage to get the jet reflected on something
right into your face at some point.
