Title: pressure washing conservatories
Post by: red star on November 01, 2011, 07:56:00 pm
pulled in a  couple of large conservatories on a nursing home / retirement home
have a couple of pressure washers 13 hp diesel which i use on drives etc and a couple of baby electric jobbies
for washing down etc
looking at buying another machine for this type of work

have kept away from connies in the past but in these hard times every penny is a bonus

have a telescopic pole brushes etc and all the attachments

what size pressure washer would be best suited to conny bashing  in conjunction with using my pole

Pressure washer + conservatory doesn't mean damage.

If someone hasn't got a WFP set up and only does pressure washing, it doesn't mean you can't clean a conservatory.

Turn the unloader down and use a high pressure telescopic lance with brush. like this http://www.youtube.com/watch?v=9cpRiFgJ1vw

or ladder up to gutter, car brush and degreaser and scrub. Again turn down the unloader, turbo nozzle the ridge crestings and rinse at low pressure. No damage done.

wfp sounds like it may be the way foward how do you remove the stubbon green algie staining and black streaking
is there a good fluid that can be sprayed on to ease removal
Virosol ;)

Rinsing off at low pressure via a pressure washer is no different than using a hosepipe connected to their tap or even a heavy downpore of rain.

Oooooh ooooh pressure washer = damage 'cos it's powerful. Nope.

Half of the people on here don't know how to start a pressure washer or how to hold a lance but claim to know what one can damage.

the wrong tool in the wrong hand is always a bad thing,

We pressure wash cons and dont get and issue at all. if your going to blast a seal or under the peak then  expect leaks, low pressure to put viro sol on scrub with a wfp and rinse off with pressure washer. we run a hot water pressure washer and this works so much better then cold water.

well that makes sense ;D ;D If its no difference than a hose and tap than why not use a hose and tap  ;D ;D ;D instead of extra expense running costs diesel petrol etc... U tell me how he is reducing pressure on an electric karcher most cheap ones are set pressure ??
Some finials are fixed via double sided tape stick a turbo on it and will land 3 doors up lol .... But up to U... down here we work for several local conservatory companies if we used washers dont care what pressure they wont use us... full stop ... but what do they know they only make them  ;D ;D ;D Luv ya Lee!

done another today used the same method small electric karcher pressure washer with telescopic lance wetted up then applied tfr then washed down  then all wall glass cleaned trad
no leaks or issues
seems to work ok and quicker than using wfp and a better and quicker clean

both have been large connies well made
not the cheap mass produced poope you get on the back of a average domestic house
proper sealed sections rubber  consealed drips and mastic sealed with nice chunky sections

Not every house has an outside tap. Not every house is accessible to an internal tap. Not always is the customer home for you to use an internal tap.
For low pressure without turning your unloaderor even so for a shiite toy Karcher, use a low pressure nozzle, couple of quid. If using a standard(again shiite)Karcher lance where you can't add a low pressure nozzle, get rid and buy a trigger with an M22 Karcher fitting for hose to fit to and add low pressure nozzle, either straight to trigger or to a lance.

we use them. 5.5 hp petrols running 2500psi

the diesel unit i  have is 13hp  that i use on drives etc  i thought this would be to powerful even turned right down
so used a  electric karcher unit i think it runs at about 130 bar pressure together with a telescopic lance and a fan  jet attachment which i generally used on cladding seemed to work well

but looking at buying a new washer at the weekend
thanks for advice

we have a 24ft lance and a wfp
never had a problem with it and we have done a fair few in our time,
if you intend on pointing a jet at a seal for any length of time or under the ridge expect problems

do you use any cleaning liquid or just rely on water
Title: Re: pressure washing conservatories
Post by: DMC Window Cleaners Ltd on November 03, 2011, 07:12:33 pm
we either use tfr or viro sol depending on what needs cleaning.
and if just light green alga then just pure water
