A low water
pressure rate (up to 100 bar)
is fine for this. Wooden items,
such as decking and fencing,
should be cleaned with up to 130 bar water pressure.
Then, hard surfaces,
such as block paving, patios
and concrete driveways,
are classed as heavy duty
use where the water pressure
can be 130 bar or more.
It is typically recommended to
use a pressure washer with at
least 2000-3000 PSI when
cleaning tough surfaces
like concreTE.

Pressure - Rated bar
is the average pressure
a pressure washer will
reach while you use it.
Higher pressure is best
for tough jobs, while
light jobs are better
suited to using less
pressure.
Another factor that
affects how well the
pressure washer will
wash your car is the water
pressure available – you need
a minimum of 80 bar, but it need
not be above 200 bar. It is not just
the pressure level that determines
how effective the clean will be though,
but also the amount of water delivered.
100 Bar pressure is equivalent
to 1450 PSI, meaning it's on
the lower end of force offered
by some pressure washers,
but will be perfectly suitable
for smaller scale jobs such
as cleaning cars, bikes and
garden furniture.
