Deosan Red Label Hypochlorite dilution for paving slabs

[BigFoot]

Never attempted soft wash before, was planning to test this out on the paving slabs and an unsighted wall at the back of my house. There is no information on the strength of this particular Hypo on the drum, I picked it up from a farm shop while I was out and about today £14 after vat 20ltr. Good price? Anyway what strength is it and recommended dilution, its called 'Deosan Red Label Hypochlorite'.View attachment 8383

From what i can see online i reckon it is 11% but i may be wrong

 

[Eviestevie]

As above its 11 percent I've used it

 

[simon]

i use that as well, there's a mad little clock type thing on the lid that points to 11

i tried it out on my garden walls & path started at 4-1 then gradually got stronger untill i could see what it did neat

On paving slabs I wouldn't dilute it very much, maybe 1 part water to 2 parts chemical. Any more diluted and it will dry out before it gets the job done.

Thanks for the feedback, put on some old jeans and goggles and get to it!

I use 2 to 1     2 water and 1 Hypo.  

£8.75 + Vat at Mole Valley Farmers. Less than a Tenner.

You need 10l hypo and 15l water to make a 25l drum of 4% hypo for slabs

Add some surfactant (a good squirt of fairy will do to test it out)

For stubborn black spots put a little neat in a hand sprayer and spot treat where needed

No need to go stronger than that

Do you have to rinse or can It be left to dry over a couple of days

This situation is becoming more common by law the manufacturers should put the strength on the labelling but the stuff we have doesn’t have it in the drums either but us it’s 10% strength that’s what I would go by for dilution ratios .
lol just seen this post is 6 years old ???

It can be left but I personally feel it’s good practice to rinse it down just in case kids or pets get it on them , some say after 1 hour it’s dead but I don think that’s necessarily true , so I would rather be safe than sorry .

We were taught it's only safe for animals when dry

Some say after an hour it’s safe to pets and kids as it’s strength has gone , but I have always been sceptical about this and would always rinse down unless it’s a roof or an area that cannot be accessed by anyone, just to be on the safe side . As a side point I have found after a couple of days applying hypo to roofs the smell has gone then it rains and it smells like it’s just been applied, so wondered if it sort of re invigorates the mix again ?..

Well it breaks down to salts, that algae actually feed on, so when it rains the salts will dissolve again so will smell

So if it’s smelling of bleach then I assume it’s still active ??

That's beyond my payscale

I agree completely. I know what @Part Timer is saying but I feel much happier knowing it's been thoroughly rinsed. Whether it matters or not it gives me peace of mind so is worth the rinse and helps get rid of the smell....probably.

We always rinse apart from roof jobs

So I went for a 4 to 1 ratio left it over the weekend and then and the result is great, does smell of chlorine still but that could be the gravel holding the moisture. I am going to test different areas till I get the min strength needed for the job a bit of trial and error should be fun

Gravel retaining some of the hypo mix is all the more reason to rinse - what about pets or wild animals walking on it, or people?
And the stronger the smell the more questions you'll get from customers or neighbours about what exactly you're using. Passing it off as an approved biocide is one thing, but chlorine is another matter. It was weaponised in WW1 after all.
Obviously it's your decision, but personally when I leave a job I like to know the hypo is rinsed and the smell is dissipating. How would you handle a visit from the council?

Hi k in Kent it was all done on my own grounds as a test it was further rinsed today and there is no more scent lying around

Hi k in Kent I'm new to this so I have started around my own home first as to see if it can be implemented safely. Pleased to say after a further rinse today the smell has all but gone. Going forward I will be going for a 6 to one ratio
