Hi i have read that you can put a treatment down on patio and drives to get rid of the black spots and lichen etc that wont come off with the turbo lance.
What is the chemical called.?
How do i put it on?
Is it mixed partly?
Where can i buy it ?
How much does it cost?
Any help please ?

47 read it surely somebody knows

Sodium hypochlorite works, that's what was advised on here. Do a search on it and lots will come up. Use with care but very effective on the black spots otherwise. Can be easily bought locally, but shop around as prices vary ask for good strength 14% proof as works best. I get mine from a swimming pool chemical shop.
-
Thanks
Just the answer i was after.
Thankyou very much. ;)
-
There's some on e bay
-
easily available but only info for pools how would it be applied to paving? Neat, Mixed left to dwell or just sprayed on then pressure washed off ????
-
You can buy it from me £15 for 25 litres. 15%. Pick up only
-
I would but your to far away lol,
What mix would you do with 14%
-
how is it used for best results ? and what is it best used on ?
-
Some guys on here use bundles a week, I don't so much but when I do I start mixing 5 to 1 water / chem and work my ratio down until I get the desired effect. Sometimes you may have to use it almost neat to get the result. I mix and apply it in a watering can and leave it to dwell for a few minutes then wash off. Some use the chem injection on the pw straight off.
Eitherway, use a chem respirator otherwise you'll fall over with the fumes and look stupid! Cover yourself all over cos this stuff burns and will even burn through some fabrics and shoes so PPE up appropriately as this stuff is serious. Watch the wildlife and grass however if you put down enough water to rinse it'll dilute well enough and shouldn't be too problematic if your careful.

Can you use this on con roofs instead of virosol etc
-
I wouldn't of thought so cos of the chem would attack the rubber seals on the windows also think that it'll have a pop at the glass too!!!!! very powerful stuff just really want to keep it on the floor....
-

is this just the same as bleach?

No mate. It is bleach but it's not your domestos household. Not to be underestimated on the harm it can cause.
-
I have tried bleach (household stuff) on lichen sports before and I may as well have not bothered - it did nothing.
I'll have to get hold of some of this.
Can it stain or discolour surfaces?

Hypo could literally melt your face off if not used right!
Def wouldn't be spraying it about all over conny roof's, unless you want the roof to be the last thing you remember seeing, literally!

Cheers ian defo floor only job then.
1 question
I have a customer that has natural indian sandstone slabs.
A is it ok on them
B what mix would you use on the slabs
Cheers cliff
-
Another question
I have a block drive to do on thursday which im going to try this chemical,should i rotary floor clean it 1st get all the moss muck out between blocks wash all slurry away and then apply chemical leave and wash away again.
Or just apply the chemical 1st and then rotary floor clean it and wash away.
I ask this because i havnt then got chemicals flying around everywhere while im getting rid of the worst of it.
Whats your thoughts
Regards cliff

Cliff, check your email

You'd be wasting it on block paving mate applying before.
We clean block paving just by pressure then apply after should we think it needs it for any heavy places.
Same with Indian sandstone. Take off what you can with pressure then no doubt lichen blackspots will be visible or tough staining from overhanging trees like in this video below where we clean and rinsed all with just pressure revealing the stains. Then brushed on hypo strong and left it.

we use lots of hypo, same as blastaway, put down after fisrt clean, wicked stuff!! make sure you cover all your clothes tho, or like us you will be walking round with white splash marks everywhere. i'v tryed spraying it but have found watering can best method, for drives and patios
-
Cheers all seems best method is to clean 1st then see where you need to apply after,
Will try this method out on my next clean.
Thanks every1 ;D
Any1 else feel free to put some more advice up if you have some.
