Definitely more surfactant, pre-wet first - 4/1, scale down to 3/1 if needed then gentle steam if it's stubborn, the key there is to use the heat to your advantage, full steam not 21lpm 150 degree, 5lmp 150degree or less and you'll be achieving actual steam, it would clean the last stubborn stains perfectly with no lines to stress about trying to even out. Pressure washing to start probably caused you a harder longer day there plus the lack of surfactant, the hypo was mostly running away before it had chance to deep clean the stubborn darker algae. Slight learning curve with render and hypo isnt always needed but i definitely would of hypo'd on this one like you did. If it's green algaae only though just biocide it and within a few days it'll be perfect, no washing needed at all.
All this info is good but pointless in this instance. 15% hypo applied on wait and soft wash off. Much quicker and better results than wasting time pressure washing it all
Think your hypo might be off Dave, I soft wash at 4:1 on that type of render and don’t pressure wash and usually comes up gorgeous I’d say the hypo might have had an issues mate but great job nonetheless
15% hypo at 4:1 with puresurf should work fine, no pressure washing. Maybe extend the dwell time and apply a little more product before rinsing. Some of the streaks could also be non organic or staining from the gutter contents. Caistic TFR or Synergy Pro may help or maybe even a little acid depending. Good first job though. Thanks
Hi Dave, I pre wet surface first, 4 percent hypo with lots of detergent , dwell 20 minutes , use xjet fan, re apply hypo 5 to 6 percent dwelling 25minutes , x jet rinse, then I apply a biocide anti mould and mildew roof treatment 10 to 1 mix ratio and leave, job done , ps also can use a small surface cleaner 12 inch at 750psi per nozzle 👍
@@squeakycleandave1 Hi Dave , i should have said xjet rinse with the fan less chance of striping , I apply with low pressure pump and water feed brush and pole 👍
I think you should have used more surfactant to let it stick to surface better as you can see the run off is quite a lot that what I do always works great at 4to1 ratio
Its a great video.... offers great information to all in the video and the comments....... looks like enough surfactant was crucial here, but still a big improvement , you are capable of doing the best possible job Dave because it is in your blood so to say.
Hi Dave, looked great in comparison.... Softwash Guy on UA-cam specialist in this area, does fmgreat videos on these render type jobs. Amazing transformation in every job he does.... Biocide it all after rinse down as kills any remaining spores
Great vid, but I would of only used softwash on render. I normally apply from bottom to up. That way less running. But everyone has own way. Looks like hypo was dodgy mate
Nice to see when a job doesn't go perfectly. Was the chemicals being old and not as effective? I'm a little surprised that after doing a course you didn't gain enough experience to have a near perfect result
Smout pressure washing also a good shout out to Dave and himself teamed up on a job, maybe something you could all do, Jake (smout pressure washing) does a live near most mondays at 730pm a type of pod cast live on UA-cam, have to say its great, very informative and nice to see someone do very well but also giving tips and ideas.... Great workmanship by you all and its a credit to you all. Regards Al
There are few good factors why the result wasn’t good, your softwash mix not that good as it runs too quick and not enough time to stick to the walls. Not all stains are organic so you need to use different chemicals for different stains , also why didn’t you use heat ? Heat is good from removing stubent stains. I am surprise they didn’t tell you about these in the course you attended to🤔
When dealing with chemicals there imo should be a minimum course one should do to work with them, maybe not the prices they charge but something as the damage that can be done just spraying willy nilly ain't good.....

Think it was more likely to be cold and the Nu clear is only 10%
@@squeakycleandave1 ahh 10% makes sense bro

I have got an JXet but as it was a Gym ii decided it would be safer to apply with the backpack.
Ive defiantly learnt a lot from this job.
@@squeakycleandave1 Hi Dave , i should have said xjet rinse with the fan less chance of striping , I apply with low pressure pump and water feed brush and pole 👍
Maybe a biocide treatment
Leave for 6 weeks . Come back and wash then reapply a hypo mix and normally gives exceptional results.

At a guess i'd say a stronger mix and i can't see any suds. so the hypo is not dwelling but im sure you had that figured before you started
I love soft washing, something about the bubbles running down the qall
Fantastic result to be fair Dave well done
Thanks David 👍
Lovely job Dave
Thanks neil
Not a great advertisement for the pureseal course if you come away from it with that knowledge base
Its not the course it was applicator error
Nice to see when a job doesn't go perfectly. Was the chemicals being old and not as effective? I'm a little surprised that after doing a course you didn't gain enough experience to have a near perfect result
No the chemical was new. It was down to inexperience and nothing to do with the course
Yeah that rinse was far too quick, if there was enough decent surfactant in that mix that should have taken ages to get rid of.
Don't be to down beat David everyday is a school day chin up
Hi Dave, great video as always 😊
How long did the job take start to finish. Tia
Joe
I was there from about 9:00 until 3:00
Well done, you can’t make it new
Would have loved that job.
Someone in the comments mentioned your Chanel. I will take a look and subscribe later 👍

Exactly, and why you need a wetting agent to keep it in place oxalic acid & glycol 100% perfect results in a flash every time ...easy money!
Did you say you used heat
Yes bud
This is basic stuff! Some one in my area went on the same course and promotes he's the most qualified in the south west haha

Great job and thanks for posting this nasty one.
