    Following on from my previous thread, I ordered a ik sprayer to use with hypo. Just bought 20 litres of sodium hydrochloride 15%. Can anyone recommend what ratio to mix this to clean patio and roofs?

    you'll need to research the surfactant to blend with sh,personally i would forego all this and buy from benz as its pre blended just ready to add to water,its simply not a case of turning up and splashing hypo all over mate-accidents happen that way,sorry just saying how it is,just give the benz website a read to learn some more and to be safe in what you do,

    I have been using Paveclear from Sealers Direct, very good but very expensive and bleaches my clothes!

    Any suggestions for a good, cheaper alternative?

    I have been spraying everything after washing including slabs and concrete, should I only spray block paving?

    Benz has a free pdf download of jobs and the appropriate chemical to use for it
    Quite handy
    Only thing is Benz is expensive compared to hypo

    Depending on the floor ur cleaning, I mix hypo 3/1 with some washing up liquid to help stick, but start off with say 5/1 and leave it down for about 20 mins and see how it is, I have also used hypo neat, and this job am on at the moment, av disconnected all me bits from wfp setup and am adding 20 ltr barrell to a 650 ltr tank of water and running it through me hose and out me brush head some 200m away, I find it safer to apply hypo to roofs through wfp set up as it takes away the risk of overspray.

    Hypo is good but don't go throwing it about as it can cause lots of problems so be careful using it

    I am just getting into softwash but am happier with running through wfp than spraying chemicals around from the ground what with wind etc

    So assuming your hypo is 15% ish you are using at 2.5%- 3.75%
    That's not too strong or too weak imo
    I reckon that's what i will go for at first
    I did a driveway earlier mixed 50/50 so 7.5% which is strong
