Does anyone have a softwash roof cleaning set up
-
I softwash - but according to others on here my definition and use of equipment is wrong so you'd better wait for the softwash guru to come along ;D

What is your set up I'm looking at 8gpm 100psi pumps but can't source one
-
Evening,
What is your set up I'm looking at 8gpm 100psi pumps but can't source one
What exactly are you looking for?
30 odd LPM is a massive flow for soft washing especially in the UK where methods are very different to the americans.
Are you looking for a full acid pump? How would it need to be driven by engine or electric motor?
-
I am looking to set up a van based system I have a 1000 ltr tank already will add a 250ltr mixing tank comprising of water hypo and a surfactant pumped through a 12v DC CHEMICAL RESISTANT PUMP to a 50 mtr hose operated from a ladder to spray down 2 storey house roof on YouTube they are quoting 8 gpm at 100 psi can you help
-
I either dial down my gx390's in combination with an X-jet of use WFP equipment and apply through that

Sorry image is poor, horrid day and I only have an iPhone
Darran
-
Can you run chemicals through your pressure washer pump
-
I don't, that's why I use the X-jet - mixes upstream
Darran
-
Never through the pump - you could use a chemical injector. (Darran's too fast on the keyboard! :D )
When we build our systems we use petrol engines coupled to one of two pumps - the first 15 bar at 12 rpm the second 30 bar at 30 lpm both are of viton acid resistant construction so can even handle hydrochloric acid.
12 v is more complicated and we have found using a smaller flow jet pump.

Ben's your man, he built us a fantastic bit of kit, good price and lovely bloke to deal with. And by the way Ben, any thoughts yet on my new project?? Cheers

I've got a chap coming this week who might shed some light on it - drop me an email with a rough idea on what we want to do so I can get have a look with him.

Of course - I can give you a call in the morning or first thing monday?
Cheers! Ben

Thanks call me Monday morning thank you regards David

Talk to Chris Scott this is right up his street
-
Another option you could use be it from ladder or pole to apply chem

Wfp Backpack, x jet and sniper nozzle does the trick for me.
-
What's a sniper nozzle?
Darran
-
Its a long range low pressure zero degree nozzle i wasn't a fan at first but use it loads now.
https://youtu.be/Wfotfv4bIek
-
Yes found them, @ £15 well worth a try.
Where do you put a chemical pick ? I have them at the pw but they don't seem to draw chemical when using 50plus meters of hose ???
Darran
-
Chemical pick up at the machine works according to the Venturi effect whereby a pressure moving forwards creates a vortex with the hose and creates a back pressure which draws the chemical upwards. Strictly speaking this effect cannot be guaranteed to work over 10-15m though of course it usually does. :)
-
I just use it to pre wet and rinse off, i think you could put it on an xjet but never tryed
-
Rarely for me :'(
What nozzle would be best to encourage the correct vortex and back pressure ?
Darran

Strictly speaking this effect cannot be guaranteed to work over 10-15m though of course it usually does. :)
That's why I guess some don't like downstreaming as also using strong chems can destroy high pressure hoses, couplings etc eventually too.
-
Precisely why I never fit chem pickups to our machines - I don't take them off the Dual machines but I don't fit them. I always reckoned the GP stainless Soap Shooters which pick up at the lance.
-
That's pretty much the same as an X jet then
Darran
-
Pretty much - just stainless steel and less expensive.
-
Yes I'll give you that ;D
Darran
-
Those gp soap shooter seem cheap for a good reason.
I suppose they would be no good if wanting to change the type of nozzle you use as is a fixed so say long range. Also you can't run the chem mix as low a 1-1 ratio if you wanted so all in all a waste of time surely Ben?
-
They offer the same adjustment as a downstream pick up - when combined with a proportioner (if you want to use them) you can get more flexibility. As for the fixed jet - most of our customers use them for washing trucks, buses and cars on the electric side so it makes no real difference.
-
So what set up would you recommend for K-render cleaning Ben?
-
I would go along the lines of the american systems.
The best way would be with a teflon air driven pump.
Failing that a pump designed to handle acids and chlorine's.
-
For k-rend cleaning.
-
or
-
Thanks Chris, Which one do those petrol driven sprayers do you prefer (including the pro's & con's) as I take it you have both?
-
I don't have a favourite.
The tank version is handy for cladding …we run 3 waterfed poles from it with a soap solution . Downside it takes up a fair amount of room in the van.
The "pump" only is good when used in conjunction with a Dosatron feeding it with bio-cide. It cuts down the amount of waste product at the end of the job and insures accurate chemical application,
Both machines are perfectly capable of either job. For cleaning K-rend they are a "must have" otherwise it's like trying to clean driveways with no pressure washer.
-
Cheers chris ;)
-
Ask Ben to build you a "tank" version with a demountable pump…best of both worlds.
-
anyone ever used benzs cleaning solutions for softwashing????
-
One is Bleach and caustic the other is Quats….whey pay over the odds for either product?
-
Thanks, softwash is something that i would like to add to my pressure washing and it seems to be a mine field, as every manufacturer has varying opinions. All I really want to know is a sytem that can be used that will mix the chemicals and produce enough pressure to clean a typical 2 storey house..
-
The simplest method is X-jet or the one Ben has mentioned, they fit to the end of the lance, so no extra pumps/motors and take up very little room, downside you have to move a barrel of chems every so often.

It's not a mine field…there are two basic chemicals Bleach or Quats. Get the msds sheet form the supplier…see which one it is.

Just try not to mix them ....

And a chloras mix by any chance? ;D

Never spray bleach on a vertical surface….it's too dangerous.

Are you speaking from first hand experience then chris...? If so go on do tell us what happend.
If not then why not?

Thats one point Smurf …it's hard to control drift.
He is a clue for point number two…effects on Organic and /or metallic surfaces.
See if you can figure it out yourself…maybe nudger can help you.

No ;D
I generally brush chloras on for that same reason be it hard surface areas on the ground or walls..
You do have to be careful as is also corrosive on some metals not to mention harmful to aquatic life, organic life, pets, kids etc too. Apart from that it's fine ;D

Spot on ;D

Thanks for the info. Have ordered a x jet from the USA which should work on 2 storey buildings.. would like some further info on the extended lances I have seen on various videos..
Sorry for being thick, with the x jet it draws the diluted chemical from a container? So does it not further dilute the chemical when using the lance with the x jet at the end??
Are the chemicals available on the market just a dearer form of hypo??
Trying to educate myself before I clean my neighbours render.
-
Following as I am looking to gain as much knowledge as possible before i tackle my own roof as a trial 👍 Interested to get any advice on a suitable wfp to use (pros and cons) and if anyone has any links to a soft wash in a box type of idea in the UK that would be very much appreciated 👍

X jet draws neat chemical and then mixes it with your water flow, you get a set of Venturi's ( I think that's the name of them ) which allow differing mix ratios
I've adapted some gardiners clx poles to take the X-jet which also has a shroud around it ( stops wind drift when applying to walls etc ;D ) and other pressure washing bits.
I'm sure our resident chemist Chris will be more than happy to list plenty of options - but hypo is pretty much the most effective chem for algae ( just be aware it has its drawbacks and dangers)

X-jets are as far removed from "soft washing' as you could possibly get. X-jets need around 3000psi to work (and a pressure washer). "UK' Soft washing is the application of a chemical (to do the cleaning) typically we use around 10bar at 10lpm …reducing the risk of damaging to the surface (althoughh chemical damage may occur). "American" softwashing consists of spraying bleach at everything and anything .
Below is a specifically made pump aimed at the UK softwash market.

Own tank for pre mixing.

Info on softwash chemical.

There we go, told you the expert would be along - thx for the info Chris, much appreciated.
Do you spray this on vertical surfaces ?
Darran
-
No problem…glad I could help.
-
So do you ?
Darran

Darran
Smudger if you open the pdf that chris has posted you will find out.
-
So do you ?
Darran
Yep…(sometimes) we spray on vertical surfaces.
-
Thanks, if you don't mind scott where can you buy those specially adapted pressure washers from?
-
Rutland pumps.
-
Thanks once again for sharing your knowledge, have spoken to Ben and will be paying a visit soon..
-
forgot to ask, will I require any special licence from my local authority for the use of chems for soft washing?
-
Precisely why I never fit chem pickups to our machines - I don't take them off the Dual machines but I don't fit them. I always reckoned the GP stainless Soap Shooters which pick up at the lance.
do you have a link for this? cheers
