Has any one used these for block paving

Is 100bar enough to get the gaps clear of muck even with hot water?

I know they are good on sandstone etc

im not shore m8 im curntly tralling throu utube  :banghead3:

They're great on roof tiles with the mini fsc on a wfp

You're not on the pressure/softwashing fb group are you?

Couple of guys on there using them

dave will a pressure washer be ok on a lite pressure for sills on these new builds ?

If you mean the concrete ones I hypo first then use a 40° (white) tip 

Have used 25° with no problems on 3000psi at about 12lpm 

im thinking just no heat m8 just a 15lpm pressure washer turned down to get them 50% before soft washing

I do it the other way round as I find a bit of hypo helps take the blackspot etc off easier so can use less pressure.

@Pjj does this type of work I think.

We do a lot of softwashing , a bit of pressure washing with cold water , and a lot of window cleaning with hot water , 99% of the time if pressure washing we hypo the paving, block drive etc first then pressure wash off job done

I do plenty of block paving and do it the same way as you.

Always wary going high pressure on sills

Generally on  sandstone sills we just softwash and they come up like new
