Just wondered how you would go about cleaning render walls on properties when they are surrounded by water so using chems might be a big no no?

[Matt.]

It would be hard to get clean without chemicals
What's at the bottom of the wall, would u not be able to use suton along the floor under the wall to collect waste,
Plastic sheeting into a run off area or some guttering along the bottom of the wall to collect an again run it off into either drains or somewere better than going Into the water

Great thinking Matty... Nice one 

The property in question is a posh second home for a client I have to look after with the render walls decking etc all going green. It has a stream running along the front and back that runs into a lake. Lucky enough the bottom of the walls are just grassed so Like you say some sort of recovery system using guttering  and sheeting might be a good workaround to minimise the risk of too much chem entering the soil and making its way into the water. Not only that the chem run off once caputured could then be recycled.

[Matt.]

On the second pic it look easy enough to sheet out, use the slope  to ur advantage.

If I sheeted it out an used the slope, I would maybe funnel the sheeting into a barrel or 2 especially if you can re use it, might need a bit of guttering to direct flow into top or barrel,  or just use a bigger one with a hose fitted to the bottom, if it's down hill will drain off, if not might have to take booster pump to job and plug in,

Sheet out bottoms of walls and maybe put guttering along each bottom to collect, or use gutters with end caps on if they not water tight a bit of plastic carrier bag to make them, then you just have to empty by hand, jug, cup or if the booster pump is available use that to transfer the chemical out the gutters into barrells

[Smurf]

Sounds like a good plan.

To be honest for quick results and max profits I was tempted just to use a hypo softwash mix and brush it on because of the zinc roof etc and the amount of water needed to wash down afterwards on reflection using hypo maybe not a great idea on that one.

Looks like I'm going to have to go down the slower and more expensive route now as I'm not geared up for softwashing.
That's using an Algopro type product as would be the safer option for surfaces but still is harmful for aquatic life if not careful.

Due to budget constraints in buying new softwash kit can anyone advise the cheapest and best way to apply algopro type chems as I can't afford to fork out loads of money for some decent kit that the likes of Chris uses at this present time?

All I'm after really for now is maybe a decent enough chem resistant 12 volt pump suitable with a high enough bar & flow rate. Then adapt a wfp to spray it on the walls and give it a scrub if need be.  Any help and advice would be appreciated.

I don't mean to sound tight but due to ongoing health problems money at the mo is a real concern and I don't want to get into debt buying expensive bits of new kit that I may not be able to fully utilise (pay for itself) in the near future.

[Matt.]

If I had a budget of 10k I would still go down the wfp route before I spent any money on new kit, get some experience and see we're the mistakes are made first.

Why would you waste money on something that can be built up using an alternative 12v pump and kit already in ya van.

Fatter hose than what we wfp with and bigger jets in brushes

[Rob@Blast off]

A wfp and backpack is perfect for render.
People will say that the chems will kill the pump but mines about 9'months old and has only been used for chems and it's still going strong. If overspray is an issue then an x jet is good.

Wiltshire Chris why?

I would of lent you the gear to do it.

Wow! That's very kind of you Chris

[ray mck]

You can borrow my backpack if it helps .

Many thanks Ray but I will see if I can coble together a 12 volt hi flow pump box for now using maybe this type of pump.

That way I have the option using a chem pump box to either stick it on a trolley/sack truck and use it mobile using 20 ltr containers to feed from or static in the van to directly feed chems from the smaller 250 litre van tank as I have two tanks in the van already.   Thinking about it I also have a spare digi controller that I could use on the chem pump box so can set the flow that would be best suited for each job in hand. 

Sorry if I'm waffling on chaps but just thinking allowed the cheapest way to knock up a 12 volt van type chem delivery system that could be also used mobile on a trolley if need be.

[Matt.]

I think this will work no probs as far as a van set up goes, it's exact same set up as wfp delivery system, just using the rite hoses to let flow through.

As for a trolley set up if the pump is running at 10 lpm the barrell will be empty in no time, so may need a constant flow of water plus chem ( another person required ) or convert a trolley similar to Darran done to hold more water.

I would just stick to van set up, get the pump rigged up to spare tank, strap it to other tank and connect hoses up, and were jobs come in that access isn't available either add more hose or by this time enough jobs will have been done to invest in something that's manageable for yourself to move,

Maybe some new pole hose and jets, connectors and pump this may be your only out lay

Exactly Matty as would get me started for sure.

On that property I would like to try a quants based product rather than using hypo.

That way I don't have to worry about overspray/run-off damaging the zinc roof, metal window frames, metal downpipes, wood cladding, paving, decking etc when applying. as can all be treated with the same chem safely I hope. Not only that the outside table & chairs need going over too but the wooden foot bridge at the front might be a bit of a chalange to do.

Just wondering now what would be the best type/size hose, connectors etc  to use and best way to rig up a wfp for the task.  I see in that algoclear vid they use a garden type sprayer nozzle tip at the end of the pole and really saturate  the walls down.

Anyone know the best way to go about this and best/cheapest place to get all the parts needed that may already have built this type of wfp sprayer before.

[Smurf]

Cheers Chris, I will take a look for ideas 

[Smurf]

Just reading the algoclear pro sds  http://www.roofclean.co.uk/pdf/AlgoClear-Pro-Safety-Datasheet-2014.pdf
that states:

10.5. Incompatible materials
Materials to avoid: Soft metals (aluminium, zinc etc.) Strong acids...

That means I'm back to square one then...FFS 

That job I'm in two minds to say stuff it and just get the client to find someone else as to be honest it seems more hassle than it's worth now.

What would you chaps do?

[chris scott]

I would phone me …before I go to bed and whilst I am in a good mood. I might if the mood takes me explain how to do it.

[Tadgh O Shea]

Nice offer Chris,  i have often phoned Chris myself great guy to talk with and really knows his stuff he won't put you wrong Smurf.  Tadgh
