A question to those who have used a pressure washer: Was it used to get
all the paint off or just the loose paint?

Anything that that doesn't come off with the impact from a rotating
pencil jet of a pressure washer at 2" or less isn't going to come off
anytime soon. Beware that if the mortar is a bit iffy the pressure
washer will have that out as well...

It's very messy job, you'll get soaked and filthy from paint flakes
and anything else that detaches from the wall. Paint flakes will
travel considerable distance given a chance. I had proper scafolding
put up(*) which made access very easy and gave something to attach
tarpulins to behind the work area to contain the flying paint and
water. Also cover all the ground under the work area and at least a
couple of yards either side.

(*) Well worth the £2,000 or so it cost for 6+ weeks. That was for
full access to three two storey gable ends (3 levels) and 10 m of two
storey wall (2 levels).
