Title: SH mix strength.
Post by: Slacky on February 19, 2018, 10:37:09 pm
Last one guys ;)


Quite often you see people referring to the concentration of the SoftWash mix that they use for a particular job or other.

Often the figures quoted are 10% SH or 5% SH. This being 1 part SH to 9 parts water or in the latter example 1 part SH to 19 parts water.

The gear sold by the farming outlets is usually about 14%. So does this mean that you have to dilute the mix down from 14% to 10%??

Bit confused, sorry. Any help would be appreciated.

Everyone seams to do things differently we use hypo with 10% strength we put 4 ltr of water to 1 ltr of hypo Ime no mathematician but this mix workes well for most applications on some surfaces you might need to reapply a couple of times leaving a dwell time of 20 -60 muinets between applications , not being rude but I would of expected to get that wood looking much better than that depending what the contamination is

Doesn’t that mean you’re using a mix of 2.0% then if you’ve added that volume of water?

I've never known anyone in actual practice to nail it down. If you look at you tube comments they will ask what you have asked...... if its 14% and you diluted so many to one isn;t it actually  [insert figure] to one.. and they say..yeah. All that i've seen and all that i've done is top up 25 litre barrels about a quarter hypo, rest fill with water for a strong mix.... less for a weaker one. Do your own maths but most are guessing.

You can get different apps which will tell you what volumes of each you need to get the desired strength you require.
My understanding is that after 20 minutes of it being down, it is used. So applying one coat and waiting 30 - 60 min is just killing time. Don't let the mixture dry but it is best to rinse and see the results and then reapply

Erm, now let me think...... Do I do pressure washing, soft washing and render cleaning......... I'm gonna have to go with yes I do use it
(where do you think I've got my black barrels from for my DIY trolley)

So if its "used" after 20 mins, why would you wait 30-60 mins for a result ? But you don't want to wait that long, you wait for a result (no timescale mentioned) and re apply ..... can you talk us through this ? I seem to be getting a confused message from you ?

On a previous post, a comment was made about leaving the mixture sit n dwell for possibly upwards of 60 minutes. Which prompted my post..
Hopefully that has cleared it for you

"So applying one coat and waiting 30 - 60 min is just killing time" he's suggesting to wait that length of time would possibly be a waste of time and to rinse and reapply if necessary after 20 mins and get the job done quicker.

And can anyone clarify what effect SH has on wood ? Say.. after a good dual soaking?

At 1% not very much by the looks of things!

I'm trying to find out if its more cost effective than the wine and spirits i'm consuming.
Its well known that SH is bad for wood, just no one is saying it. In fact they're encouraging it.....
In this thread they're giving ratio's....   ;D

When your tired it's easy to get the % mixed up or confue=sed by what % they are talking about, so I'd say the common strengths are 2,3 and 4% and using 14% hypo the calculations to make these stengths would be;
2% 3 litre of hypo add 18 litre of water
3% 3 litre of hypo add 11 litre of water
4% 3 litre of hypo add 7.5 litre of water
If useing 25l containers with some ullage for easy mixing
2% 3 litre of hypo add 18 litre of water
3% 4.5 litre of hypo add 16.5 litre of water
4% 6 litre of hypo add 15 litre of water

The more you make it up the more the quantities stick in your head but the 21 litre mix is easy to remember, it's going up by 1.5l of hypo each time to make the 21l

As far as i know Blackwash is a branded product that does have SH in it, i've seen it described as a biocide too so i'm not certain exactly what is in it.

It will kill any algy and bleach the surface of the wood a little depending on the type of timber strength of mix and dwell time : if the timber is given a good soaking with the garden hose first so that it is saturated the vast majority of the hypo and surficant will stay on the surface of the timber which is ware you want it it’s not going to do it’s job on the surface if the wood had absorbed it all , hypo is used quite extensively in the timber industry to alter the surface colour of wood to age it etc

Biocides are mould/algae etc...removers/cleaners. ‘Benz’ are a brand, they haven’t  copywritten the term ‘biocide’.
