K Rend and Hypo

[Grumpaflump]

I have just been asked to clean a wall , which is rendered with K Rend.

Is Hypo the best method and if so at what mix?

All Advice welcome as this is my first K Rend Wash.

Thanks in advance.

How big is the wall ?

If there's flower beds or grass below rinse with water first

Or if it's paths do they need cleaning also as they will get partially cleaned by run off

Yes hypo is best just spray on a 2%mix with WFP

Then with garden tap and a good long range spray nozzle rinse off

Then if any stains left give it more hypo and brush if any stains

wal is 7 metres by 5 metres but in a confined area so no access with WFP, thinks of spraying it on with my Viton sprayer and then rinsing off.

Great work horse..... handy for confined spaces and never misses a beat
