Clean It Up

I have been asked to clean the walls on a painted cream house. The Wfp will remove the green stuff but i read somewhere on here that there was something you can put on the walls that makes it easyer to remove the green stuff (algeawhatyoucallit) ;D Also they want me to then spray it to help stop it coming back.
Any ideas.

Done this on a few houses. You don't need anything but water.
Try to arrange it for a day when it's been raining hard and the walls are good and wet. It just floats off then with next to no scrubbing.
I've never heard of any spray.

I did one and used a Dulux Weathershield anti fungiside that the customer sourced. Get on the Dulux site and you will find it. Brush on, leave overnight then rinse off.

I agree with this post, also the Bentley Brush is great for getting this stuff off; the bristles seem fairly stiff, and when I did a similar job recently the green algae just seemed to 'melt' from the walls.
It was easy to do too.

I used this on limewashed walls when the water alone didn't clear it. This stuff kills it.

Ftp do you use this afterwards, and do you know if it helps stop from coming back.
Dulux or Weathershield finishing

i posted on this a while back.
Sandtex was the product i used. Very good stuff.
Water will clear the algae but it left a faint shadow afterwards.
This sandtex has to be applied and left for 24 hours. Go back and brush off.
The customer sourced this and he told me it cost £25 for 5 litres i think the size was.
I did start doing little bits with pure water to show him i could do it, but he anted this sandtex used as it claims to stop or slow down the return of algae.

Same as Mark. Limewash is porus so the algae/mould can't be washed off as easily as something like a greenhouse roof and will soon grow back. The customer took advice from the limewash manufacturer who told her to use the Dulux stuff. The spec sheet is a bit scarey - i pumped mine through my system and wfpoled it on. Customer very happy.

Could i just spray it on as i dont want it going through my pump system

yes.
I was gonna use a crop sprayer originally but i had to pump it up cos i was cleaning a high house. :)

Thanks mark i will look at what i can find .

I would be very wary of spraying it on in case you inhale it. Check the spec sheets carfefully for whatever product you use. I pumped mine and brushed it on because it had to reach under the gables of a tall house.

Use sodium hypochlorite (Bleach),... the cheap un-thickened kind in a backpack sprayer mixed 1:1 with water. It'll work in about 30 minutes, and is great for cleaning footpaths too.

I have a PA6 sprayer certificate ;D or something like that. It's been a few years since i last looked at it but i gained it when i worked in horticuture for 13 years.
