what about using a weak solution of ubik when spraying top section and brush. then hosedown to see if any difference. one can try a small patch first to get an idea how it will look?
ubik is a very different animal to tfr slippy,honestly mate,please do some more research into cleaning hard surfaces otherwise if you carry on you'll come unstuck big time-with a big bill to boot,this softwashing marlarky needs a lot of homework to understand what to use where and when and on what time scale in some instances,Ok. Is the brushing important with hypo or ubik? I just sprayed on then rinsed. I have chemtek's TFR, I guess that's the same as ubik.
no it's cos mix too weak...and technically soil can be organic and inorganic depending what it's made of.I sprayed the top photo with hypo mixed with water 6 to 1 at a guess then rinsed and no difference. is that cos dirt isn't organic?
Tno it's cos mix too weak...and technically soil can be organic and inorganic depending what it's made of.
But I also strongly agree with Kevin. Everyone should do their own research into soft washing a get a good understanding of what it's all about, what chemicals to use and when etc.
Don't rely on forum answers otherwise you won't develop your own understanding and a casual attitude can damage property, kill grass,plants,bushes even trees stone dead.
the safest way is presoak all vegetation with water and again after clean.
That way if you're careful u can apply with a watering can or even a pump sprayer (bit slow though), pressure clean and if any hypo lands on grass etc the soaking with water dilutes it enough to render it harmless.
Slippy I wouldn't bother with Patio Magic mate. A 2 or 3 to 1 hypo mix of 14-15% hypo is by far the best, quickest and cheapest way and it gets rid of black lichens and everything else. Just apply with care after pre soaking surrounding areas, leave half hour, pressure clean and soak again.
As long as you're aware of the killing power of hypo and guard against it with lots of water before and after there's nothing better than hypo
this is a wind up surely?-if its not then i'm sorry slippy you should not be doing any of this kinda work as it comes across that you have absolutely no idea on what you are doing, and that is dangerous to yourself and others,courses give you some knowledge but not it all and in the wrong hands this "knowledge" can be even more dangerous to others I see them most days on facebook-theyv'e done a course and suddenly they are experts on everythingGreat post and thanks. When you talk about sealing the sand in my block paving photos ( I assume you're referring to the photos in my first post on this thread not the ones you posted) after brushing sand in do you put silicon like the stuff used in bathrooms on the top of gap with a gun and smoothed over with finger?
You mentioned pressure wash the hypo after spraying it on. Hypo is dangerous to us wouldn't that spray a dangerous chemical onto our skin and eyes? When I used hypo once I used a hose to gently rinse it off.
Interesting point about what to spray with hypo and what not to. I guess if in doubt do spray. I guess any concrete paving slabs or block paving is fine to receive hypo same as white painted walls (probably cladded) . These are the surfaces I might spray.
Why did you say the block paving in the photo shouldn't be hypo'd?
Might do a course, heard a place in Bristol offers one
