Karcher 110 bar Pressure Washer

[Arthur 51]

Hi. If I am using a 110 bar pressure washer to clean a patio will it blast the mortar from between the slabs?

Thanks.

Not necessarily - it depends on the skill of the operator!

110 bar - alledgedly - at what flow rate?

[John Rumm]

and how crap your mortar is!

[Roger Mills]

True, but if it's not *too* crap the trick is to do up to the edge of each slab with the lance held fairly close, and then to do a quick sweep of the mortar joint with the lance lifted away by several inches so as not to put too much pressure on it.

Interesting, what if your using a patio cleaning attachment?

[Arthur 51]

Yup..figured as much. Thanks. Arthur

They tend to be far gentler anyway... probably because the jet is at an angle, and not focussed on any one point for longer than a fraction of a second.

[Roger Mills]

Dunno - haven't got one of them!

I take the view that if the pressure washer removes the mortar, it needed replacing anyway.

Thanks!

A lot of people I meet are against pressure washing and say that the paving get's loose the moment you attack it with a pressure washer.

I personally don't agree with them because we have been pressure washing for years without trouble.
