This is for Smudger and Smurf etc.
Is a 10% solution of Sodium Hypochlorite likely to be okay to use on Indian Sandstone to swell for a few minutes prior to pressure washing with a rotary on a reasonably low pressure setting?
-
Usually a 5% mix is strong enough but add a surfactant to help it sit on top of the stone whilst it does it thing. (ammonyx LOL is very good)
I find the soft wash more beneficial after the pressure wash with a fsc, then it can attack the lichens which are left and not all the crud as well if done first.
-
Hypo is safe on all stone concrete - Acid is not as it will turn the natural stone orange due to iron content
what are you removing ?
My personal preference is to pressure wash first then apply Hypo - we use 14% and for algae only its 2 parts water 1 part hypo mix for black spot its 50/50 or in extreme cases 100% applied with a pump sprayer
i have found that applying hypo first is less effective because the grime/dirt/moss resist the hypo meaning an application after pressure washing is needed

i also add a detergent - something like cherry - because it helps the hypo stick and smells nice ;D

Primarily it is only a heavy covering of algae, no black spot/lichen or anything of that nature.
I just wanted to be sure Hypo is ok on Indian stone so long as its not too strong. I'll probably go with 5-10% after letting it sit for 20 or 30 minutes and wash off with the washer.

Have you got a link for that?
-
pressure wash it then use a solution at 2 to 3 % as all the algae will have gone and that strength will nuetralise any residual spores
i wouldn't even rinse down after - once its dry its inert

Smudger, that’s not a surfactant though is it? I just use loads of fairy liquid!
The cherry your talkzing about is the same as the yanks use is it?

strictly speaking your correct but it does hold the hypo in place better than without and gives a nice smell - the problem with fairy/soap etc is that it can get rather foamy which becomes a pain to clear

I wouldn't use neat or strong hypo on sandstone as there are patches it can eat through.

Will have to give it a go

I buy the 5l fairy bottles from makro, usually put around 3-4 litres in my 60 litre barrel for domestic softwashing.
I think you’d need a lot less for patios, your not fighting gravity with surface cleaning. Give it ago, it’s cheap and seems to work very well
-
Probably cheaper using the stuff from softwash UK and it's got proper additives for the job.
-
customer didn't want the cat cleaned ::)roll
why pay through the nose using "soft wash" experts when the items are readily available in better concentrations for a fraction of the price ?
we use somewhere near 200 ltrs a month, using benz or the like would be a waste of money

I tend to ask if they want this or that done foc, there was a couple arguing over the front wall which was filthy but the guy thought it looked rustic and the wife agreed with me. You could do something like clean the cat without asking, for them to be annoyed about it as they liked the way something looked.
Watched a mark cave video and he was cleaning a wall whilst saying that it hadn't been included in the price nor was there any agreement for it to be done and he's saying it's "just good customer service". Whilst I'm watching I'm thinking about the couple arguing in the street over the dirty wall.
-
Smudger, that monoblock has came up a treat. Do you use steam or just hypo and fsc/turbo. (Steam seems to be all the rage on facebook)

That looks like a hole rather than dirt. The pain is when your waiting for it to dry and some d!ck walks across it with muddy boots.
-
I use the hypo with soap first as it makes it easier to power wash and you don't have to use as much pressure and then treat any problem areas with neat or 50/50 afterwards.
-
All good old fashioned turbo and hypo
been steaming today - ill upload a picture later !!
yes i often ask what they want included and just bundled into the price - if not for any other reason i like to do more of a complete job but she insisted that the cat stay 'as is'

The turbo is brilliant. Our FSC was made redundant a long time ago.
