Not sure where you went wrong, but I am a builder who uses this quite often for cleaning flags and walls etc and it works brilliantly. I skipped through the video, so not sure if I missed anything, but here is what I do. I jetwash the area first to get off the top layer of muck, then I wet down the area if it has already dried out, "Do not put hypo onto dry surfaces!" I then use "Neat" hypo and simple brush it over the whole area to cover the whole area. I leave it for 30 minutes making sure it does not dry out, then I jetwash it off. Never yet not brought flags up like new. I have 150-year-old Yorkshire stone flags outside my house that were nearly black, they came up looking nearly new. If you tip a small amount of Hypo onto a flag is should instantly react and, if it does not then your hypo is either too weak or it is too old and lost much of its strength.
Your unsuccessful jobs are just as informative as the successful ones. Thanks so much for sharing. You are such a conscientious and hardworking man. 😁😁
I have been using hypo for over 5 years now and have learned a lot from doing various jobs on block paving, concrete, pavers, natural stone, pvc fascias etc. 1st check the hypo strength, most are 10/11% ( which I use ) and some are 14/15%. For most jobs I dilute 1/3rd hypo 2/3rds water, no surfactant except on walls or PVC as these are vertical surfaces. 2nd check the hypo is fresh, buy from a supplier who has a good turnover of stock, store in a cool dark part of the garage. Hypo loses its potency over time as the caps are vented. 3rd, I used to apply with a watering can and rose but it's very wasteful and with more run off its more likely to affect grass bordering paths. I now use a petrol engined 120litre Bowser sprayer with a chemical resistant pump. 4th, don't let surfaces dry out, sometimes I put a double application on to keep the surface wet. Get a good plastic bristled brush to properly aggigtate the surface, brushing in different directions. 5th, temperature! I never apply when it is 4c or below. 6th, customer expectations, I inform customers that the treatment cleans 85% today with the remaining coming over the next few days and weeks, due to moss/ algae now dead but drying up and disintegrating. Softwashing is not the answer to all jobs, but done correctly it can achieve fantastic results. Keep learning and practising!
Lee, when using hypo on my path which gets covered with moss / green mould I always spray it down and leave overnight. Next day I hose it down with normal garden hose and it looks great, no need for pressure washer.
Hypo is fantastic, I use it. I get it from the local farm shop that uses it to clear the cow sheds. Brings very old stained bricks up with no jet wash just a hose, although I do a strong ish mix about 50/50.
I like a man who shows his bad days as well as the good ones. A tip of the hat to you Lee. Personally I would have done a pressure wash job first. Good Luck my friend. 🇨🇦
I've never used just hypo without a jet wash as well. I did a really dirty limestone paving last week and used 50.50 wet down for 30 mins to soak then pressure washed then another application then rinsed off after another hours soak and it came up fantastic. Few black spots remained but it was a massive massive improvement on a patio that hadn't been washed in 10 years
First thing is make sure the Hypo is not too old or it loses its strength. Secondly, the Hypo will work on the first thing it comes into contact with, so if you don't sweep away the loose dirt then jetwash first, the dirt will stop the effectiveness of the Hypo and very little will be left to work on the surface. There's no quick way unfortunately. This is just advice ive picked up from professionals on other videos.
Lee absolutely love your content mate! I used to clean patios and driveways. I found that block paving that is in a condition like that has always got to be jet washed first then apply the hypo after. I am surprised the patio looked like that after the hypo🤔 it looks like it needs more like 70/30 hypo and then brush it in and leave for 30mins then rinse off and that should bring it back! If there are any black dots still on it you can use hypo neat! Hope this helps mate👍
Did my patio today with hypo, lightly jet washed first then applied 2 parts water to 1 part hypo with a watering can. Gave it a good scrub with stiff brush and left for an hour. Jet washed it to get rid of hypo and came out looking good.
i love the dirty honesty to the video. One very honest human right there. I did a fence last tuesday and left some cotswold stones muddy, the fence was a good job but i wasn't happy with the full job due to the stones. I can very much relate to this vid. I can't help with the problem at hand as don't do cleaning but hope (i know you will) resolve the issue for next time.
Hi Lee, I do this for a living and hypo alone as a softwash will not work. I first use a flat surface cleaner and go over it, not being too fussy but you must get the surface dirt off first. Hypo at 50/50 and leave for half hour then was it down and if not good enough hypo again. The hypo is good for removing black spot and lichen, it's not a miracle cleaner
Oh dear lord , the old hypo shortcut lol. You did it right mate , use hypo to kill the green before powerwashiing and to kill the lichen and blackspot after power washing . You always have to powerwash.
That pool bleach? I use regular bleach 50:50. Watering can with a rose gets it further. I powerwash it off after a half hour. What you're doing would be good maintenance.
Powerful Jet Wash at the start, blast all the old and knackered pointing out at the same time. (Save your knees and back) once its gleaming then brush in the Resin Compound. Done in a day, nothing fancy but best results.
Use a blower , get most debris off weeds ect wet surface , power wash lightly apply soft wash to wet areas brush in , wait for 15 mins and power wash off when finished spray a remaining amount of soft wash , it will dry perfectly.....👍
In the middle of my own back garden at the mo. Plan is. Pressure wash to get rid of the excess so only Liken is left on the cobble lock with focus on getting all the soil out from between the bricks. Once the water is running clear, move onto Hypo 11% at 50/50 with a sprayer then rinse off. Then Sika sand to build up the joints then set with water with a few coats of wet finish Sika sealer.
Hi Lee,bought some hypo early march to test clean some block pacing showing early signs of algae. Sprayed a 50/50 mix and left for a couple of days. Defo prefer jetwashing. Not keen on chemicals for various reasons but I think that job was too far gone for hypo. Jetwash all day for me. So, agree with you 100%
So, it's my understanding that they hypo is good on the living stuff - in particular the lichen and algae. With that said, it's better to jet wash all the grime and dirt away, and then use the hypo on the exposed lichen that remains.
When I use hypo on my patio slabs I always clear the big weeds .I soak one slab at a time then scrub it in .I use it straight out the drum never dilute but I always do it just before rain is forecast .
Well... you tested it out several ways. I call that a win. Now you know. You got this. Your the great Lee ; ) of gardening and landscaping.. 5 thumbs up.
Wet surface. Mix 60% hypo to 40% water in a knapsack then apply evenly. Leave for 15 mins then power brush combi attachment the rinse off with pressure. Assuming you have the 14-15% hypo
Try using a sprayer with a 1:1 mix. Wet the surfaces then apply evenly, brush in and wait 30 mins. Any very dirty patches re treat and brush again. You should see a big difference! A second treatment with a 2:1 mix and brush in as before will make a huge difference :) A primary wash down will help if there is alot of dirt and grime. I had similar results at first but some trial and error soon ironed this out.
Hiya Lee, you would be a fan of hypo, what your doing is correct , just make your mix stronger 50/50 or stronger and leave it no need to swill it down. Cheers Garry. Ps no power washing required. 👍
Hi Lee,I like to give the patio a good rinse first to get all the mud off otherwise the SH is working through that before it cleans the algae etc,also it keeps working after you’ve finished and when ever you can use hot water,SH need agitation,heat and time👍 Great vids mate👍🍻
I’ve got Indian stone slabs myself and only just found the black spots of mould in them so I’m really pleased I found your video, I’ve jet washed them and now intend to soft wash with the bleach, Great channel mate love your videos 👍🏼
I have a patio of yellow and reddish coloured 2x2 slabs which become dark grey after a while. I can't pressure wash because there is no drain and I just end up in a big puddle of muddy water! So I just brush the hypo on neat to the dry slabs, and don't wash it off. A little goes a long way. Flow it on don't brush it out. The slabs come up like new. Hypo weakens over time in storage and I've tried to use it 50 50 water , but it doesn't work at all.
I've been cleaning my patio for yrs and pressure Wash first then use Hypo 3 part water 1 part Hypo, it works every time, the surface us already wet from pressure washing, I add the mixture and brush in, leave for 20 min to 30 min and hose off, DONE
I did my drive way, 38 year old pavers, never had a proper wash. I jet washed the muck first, A lot of muck came out, then i brushed in the bleach and left for an hour and then jet washed off . Once it dries it started to look good and a few weeks later it looked even better. . Looking at those slabs you got lichen, that will probably need specialised stuff or a good jet wash after the bleach
Hi Lee, have used good few times, I mix it 1/3 of watering can to 2/3 water. I honestly think it may be different effects on different stone. I did notice aswell that if it dries at all it's useless. I prefer to do it when it has rained in the morning and the ground is soaked. Best results I got one day is when I put it down went for lunch priced another job so was gone for 2 hours came back and washed it off. Also used a deck scrub brush to really work the harder to clean places. Actually using today on a granite patio. I also found that on mint fossil sandstone it works wonders. Mabe softer stone????? I don't know. 👍. Only found your vids. Fair play and cheers
Great video as always mate, it’s been a pleasure to watch this as it is to watch all your content 😄 it don’t matter it didn’t work out the way you wanted, we all learn!! I’ve never used that before so wouldn’t have a clue on how to use it, but don’t let it get to you!! I know you take pride in your work mate! Maybe in the future, you may not use it again because of the result it’s given for you, looking forward to the next one😁 look after yourself mate🤘
I use 10% SH diluted 50/50 with water in a garden sprayer. So pretty strong, but only a fine spray. Leave it on ie don’t rinse it off, and don’t brush it. No effort at all. It looks pretty good after an hour, and it goes on improving over the following days. I understand it’s different doing someone elses as it has to look good that day.
High pressure clean 1st! Use a detergent to loosen the dirt. Use a surface cleaner. Rinse off. Apply hypo. Surface clean again to remove mould & moss the the hypo has killed, rinse off. Job done. And if you rgoing to persist in using that watering can, put a rose head on it. Youll get better coverage, & use less.
Builders merchants buy masonry cleaner clean flags before re pointing use patio cleaning head on pressure wash to remove dirt. use fresh sharp sand to replace wash out from block paving. the patio cleaning head keeps the water from spraying up and will clean most paving with out any cleaning agent.
In the States they usually use the bleach soft wash on vinyl siding and pressure wash brick, concrete and porous surfaces. The UA-camr Dan's Vlog has real good video's on pressure and soft washing.
The hypo your using should smell when it's working ,should smell like a swimming pool this means it's working . It should also start to foam . It looks like the hypo your using has gone past its best and lost its strength. I always mix it 2 parts water to 1 part hypo and 50/50 if it's a really dirty job . Hype needs to be between 11/15 % and should be stored in a dark container . Once opened it will start to lose its potency so it's best to use it straight away . Make sure you purchase it from a reputable suppliers as if it's left laying about it goes off and won't work . I apply with a pump sprayer leave for 20 to 30 mins and don't let it dry out . I then jet wash it off . Always wet grass and plants with hose before starting, and give area a light spray so area is damp before applying the hypo. I don't like the smell so I add a pint off fabric conditioner to every mix ( lenor or comfort or use supermarket own brands ) this also helps the mix from drying out to quickly and doesn't bubble up when jet washing . I find it does a great job 👍
You will need the hypo to be 3-6% of your mix. So if you are using normal bleach from the store (6%), use it strait. If you can get 10 to 12% dilute accordingly. Put it on and leave it. It will kill the the organic growth but you may need to use some pressure to remove the dead material.
Strictly speaking using one part and topping up to five is a ratio of four to one or 20%. Also by wetting the surface you are diluting it further, possibly by more than half again so effectively a 10% dilution. The hypo is enough of a wetting agent so adding a detergent is not needed - also it could have ammonia in it which would give off dangerous fumes when mixed with bleach.. After many years the paving adsorbs some stains which become fixed. The best use of hypo is just as paving starts to have a slight green hue or after power washing to kill any remaining algae or moss to delay it from reappearing.
Cheers pal...yes I realised the "mix" when I was editing the video 🙈....not sure the amount spread on the floor would dilute it much but hey... I knew there could be fumes hence the mask 👍..think I need more research before trying again....cheers 👍
Gutted, you work so hard and are so conscientious. I know it will all come well, but it's time and time is money. At least it has had a good soak and the chemicals should help with the jet wash. Sleep well and stay well!
Hi mate us soda crystals is the best way it kills the moss, it is granular just spread over and leave over night then jet wash off it will malt it is what you use in drains . Plus use a bit of hard surface cleaner in the jet washer hope this helps you you are good keep up the good work mate.👍
Interesting to see this video. Just pressure washed a customers large patio and they've got some bad black spot so told them about hypo. Never used it myself either, so same learning curve as you. Didnt look much wrong with what you did from the research I've done on it myself. A lot of these pro cleaning lads do go over it with the pressure washer after the first softwash, and then once its been cleaned.
What percentage strength is your hypo? I use 14/15%. I've been softwashing for few years. I have a standard 4/1 ratio. Spray once, agitate, leave for 15mins, then spray again. Dont wet before spray. You will see it working before you agitate. As it will got white. I never use pressure washer. Will post some videos later. Thanks for great vid.
Your commitment is admirable Lee, you never give up I like you try new and different things, we all admire your work and attitude, at least its clean now with your power washing.. 😁
Hypo sprayed on a presoacked path etc at a 3 parts water 1 part hypo should kill all mold moss algae etc, a good dose of soap added will create good foam so you know where you've brushed, test a few mixes on a friends drive, just make sure its a single one, half hour should easily clean a drive. Saves dirt going everywhere when pressure washing, only drawback for me is lawns etc, can be used on decking aswell but probably about 10 parts water to one hypo and soak decking first and brush gently after 10 mins. You do a lot of good work
Hi Lee. Jim here from J.S.G.S. It's all about making a judgement on how bad the are is. That is to say, the mixture of Hypochlorite. Sometimes I have pre soaked the designated are , then sprayed it and let it to do its work and come another day and power washed it. You have enough wisdom and experience to make a judgement Lee. Regards Jim from J.S.G.S N.IRELAND 👍👍🏡🚛
Cheers mate ...yeah....after varied info i was convinced it was some magical trickery that would do the work for me without power washing..(not that i dont like the power washing)...just thought it would be a quicker route...ALAS 🙈
I normally use household cheap bleach 50/50, go around the day before using a medium stiff brush and a paint roller bucket. Then jet wash next day and point up last.
Might be an old batch of hypo, i put it down neat on damp surface with pump sprayer then agitate with broom like you did. You should see a reaction with dirt/ spores lichen etc
That black mould is difficult to remove, you need a strong mix ( 50-50 ) and leave it for days to do it's work. Might need a second coat in some problem areas. Don't rinse it just leave , one hour is not long enough for years of black mould build up. I never rinse, just spray in on and leave it and let the rain reactive it and wash it into all the cracks killing all the weeds and seeds, worked for me.
we live in a rainy area and what we use is pure clorox or pool clorox and it eats the bacteria away... it could be the color in the filler you used between the slabs. it also has to be sunny. very sunny.
Put it on full strength to start with use your pressure washer after to deep cleaning . Witch you have to take top coat of then what is ever left put 40 to 50 hipo on after and let the weather do the rest . Or just use full hipo over 2 days and leave don’t mix let the full hipo work
I spray hypo on first then pressure wash and spray again brilliant results and lasts along time with it staying clean. Then if you like spray hypo again within about 2-3 months . Saves pressure washing or scrubbing keeps clean to.
Hi mate, I'm a bit late to the video but I use hypo with great results and this is what I've found. Use the 14/15% stuff. I get mine from alliance. Never use in direct sunlight as it dries to quick before it gets a chance. Light hose of area first. Make a 50:50 bucket up or use neat if area is particularly bad and brush it onto the area you are doing, you will see instant results, white foam will appear in parts as it's doing its job. Dirt and algae will remove straight away, any green plant material will instantly start dying and will be able to be brushed away in a few days up to a couple of weeks. Let the product dry in naturally over night and then next day rinse and sweep away. I've had great results time and time again doing it this way.
Head up lee! I'm in the same boat and currently have the same views as you! I used it before and while I was doing a pressure washing job... purely to test it out, I did it exactly how you did it!!! And yes it cleaned it a little but it hardly did anything!! Anyway I'm doing another pressure washing job tomorrow and as I have some left I'm going to try a 50:50 mix and try spraying it on rather than watering can just to experiment. Happy to let you know how it goes if you're interested!
There should have been a better result so something has went wrong. Few things could be 1) is the hypo fresh? Old Hypo will lose strength and throw out your ratio 2) what strength is the hypo? 5:1 ratio is based on 15% hypo. If you have bought 10% obviously that will be weaker. 3) hypo is a aid to cleaning ground surfaces and very rarely the sole method needed to clean. You can apply before or after pressure washing (personally I prefer before). It will always need time to work and rinsed off at the end.
A bloke at work was telling me he had used sodium hypochlorite on his drive and was telling me how good it was, after a couple of years he moved house and brought me 5L that he had left over and didn't need. I tried it on my driveway that weekend and found it completely useless and after a bit of googling found that it degrades to salt water over time! Maybe this is your problem?
You need to use a hot pressure washer before applying the chemical. You have a wonderful UA-cam channel. You’re a fantastic landscaper gardener as your videos show. Keep Calm & Carry On.
Good of you to show this, I'm using Hypo for the first time shortly so found this very helpful, have you got a link for that all in one mask please, thanks in advance
I tried 5:1 first the same as you. I to was very disappointed. So I tried a 50:50 mix and couldnt believe the results. As quick as I was putting it down (with bucket and brush) it was changing in front of my eyes. From black to clean sand stone slabs. I found with the stronger mix you could see it turn white where it was really attacking it, so if it's not doing this I suggest it's not strong enough. Also getting any loose dirt/mud off first will always help the chemical get to what it needs to also
I find that pressure washing patios tends to wash out the joints. I use Thin Bleach from the supermarket diluted 50:50 brings back the finish. Applied with a rose watering can. I don't wash it off. Just leave it.
No doubt you worked hard , ive just used hypochlorite on a badly marked path what i did was pour approx 50\50 water and hypo and brush it on with soft brush leae there for about 45mins then wash off with hose it worked well but maybe its different on different stone etc.Well done anyway hope it all works out in future.
Like you say there’s lots of conflicting stuff on it. I’ve always been under impression from what I’ve seen & heard that one pressure washes first then hypo and the hypo job is more for black spot? That’s how I found out about it wondering how to remove black spot. Not tried it though client wasn’t keen as worried about her dog. I’ve used household bleach diluted in past on white rendered walls prior to washing the algae off and it’s cleaned it before I’ve even touched it with the washer. So Hypo will have some effect on the clean even if just helps slow down re-growth 👍🏼
maybe your bleach was from an old stock, it does weaken with age, i did my sandstone during lockdown & it came up like new...obviously it’s meant for cleaning lichen & other growths rather than dirt so, a low pressure pre clean may have helped followed by a stronger mix also, you can use a bio-cleaning product that, in effect, consumes the growths...great learning curve so 10 out of 10, mate.
Dampen down the surface and apply the Hypo. Let it sit for 10 mins and agitate it with a stiff brush. then pressure clean it with a patio head so it doesnt kick all the crap everywhere. Then rinse off afterwards and repeat if you need to.
Just using chemicals is not good, regardless of how it cleans it is all getting, albeit diluted, into the ground and drains, not good for a garden path that in a few weeks will be getting dirty again. A good pressure washer with decent PSI and high flow rate will get the job done with no harmful chemicals. Sure you will get it looking all good though, always turns out great in all your other videos.
How old is the hypo mate. It reduces chlorine in heat and time check when it was batch . I worked in swimming pools for 25 years and used it all the time but it does go off
Jet wash first then use the hypo on areas that need it. You need to lightly jetwash the surface first to get rid of general surface grime. Then the hypo will hit the spots that need it.
Well....this appears to be the kind of day that a man would want to rend his garments, smear ashes on his forehead , curse any handy local deity while wearing copper underwear in a thunderstorm. And YOU say "I'm not happy." Wow. Fortitude. I am impressed.
Light hose water down concrete first - Degreaser mixed with bleach or chlorine sprayed onto concrete - let it dwell for 10 minutes - pressure wash off with surface cleaner. Never fails me.
what went wrong? too dilute As for removing surface dirt first, that comes down to a commercial decision, may mean you end up pressure washing before and after the soft wash. As a homeowner I'd do that at home, for commercial purposes I would not.
Hi Lee did you buy one that was all ready diluted? And to be honest like you said its a bleaching agent not a cleaner. And is nor. Ally used for removing white and black spots of paving
@@LHLgardenservices lol it was only a thought as I e used it and was surprised how good it was. I hate days like what you had but its nice to see other having them too keep up the good work and vids

no risk to york stone with the hypo, no soap or anything in the hypo? just pour it over and brush it in. Any recommended water sealants or aftercare?
@@Iby00don't ever use it, it breaks down the stone and turns it into dust! It fizzes be its literally destroying it.
You think mix 15% hypo down to 5:1. 3% is plenty strong enough, especially if you've jetwashed most of the big stuff off.

Hi, I’m new to using SH and was wondering if you can use it to clean roofs? Thank in advance!
@@crisdeanmacdonald8483 As a general rule no, it can stain any lead work. Use BAC 50 or DDAC 50 instead. Slow acting but much safer

Use a blower , get most debris off weeds ect wet surface , power wash lightly apply soft wash to wet areas brush in , wait for 15 mins and power wash off when finished spray a remaining amount of soft wash , it will dry perfectly.....👍
In the middle of my own back garden at the mo. Plan is. Pressure wash to get rid of the excess so only Liken is left on the cobble lock with focus on getting all the soil out from between the bricks. Once the water is running clear, move onto Hypo 11% at 50/50 with a sprayer then rinse off. Then Sika sand to build up the joints then set with water with a few coats of wet finish Sika sealer.
👌👌
Hi Lee. Hypo is amazing. I use it 2 to 1. Pressure wash grime off first then hypo brings them up like new. Kills grass big time.
And forgot to say leave down for at least 2 hours 🙋🏼♂️
Excellent video, thanks Lee. I used neat & it came up beautifully.
👌👌💥👍
Hi Lee,bought some hypo early march to test clean some block pacing showing early signs of algae. Sprayed a 50/50 mix and left for a couple of days. Defo prefer jetwashing. Not keen on chemicals for various reasons but I think that job was too far gone for hypo. Jetwash all day for me. So, agree with you 100%
👍👊👊
So, it's my understanding that they hypo is good on the living stuff - in particular the lichen and algae. With that said, it's better to jet wash all the grime and dirt away, and then use the hypo on the exposed lichen that remains.
👍👍👌
Good effort man. I sprayed a 50/50 mix on a area like that. It just changed the color. My surface cleaner with SH does the job well.
👍👍👌
When I use hypo on my patio slabs I always clear the big weeds .I soak one slab at a time then scrub it in .I use it straight out the drum never dilute but I always do it just before rain is forecast .
👍👍
Well... you tested it out several ways. I call that a win. Now you know. You got this. Your the great Lee ; ) of gardening and landscaping.. 5 thumbs up.
😊😊😊🙏
Wet surface. Mix 60% hypo to 40% water in a knapsack then apply evenly. Leave for 15 mins then power brush combi attachment the rinse off with pressure. Assuming you have the 14-15% hypo
You Put your Heart & Soul in to every thing you do God Bless you!!!!
😊😊👍🏻🙏
Try using a sprayer with a 1:1 mix. Wet the surfaces then apply evenly, brush in and wait 30 mins. Any very dirty patches re treat and brush again. You should see a big difference! A second treatment with a 2:1 mix and brush in as before will make a huge difference :) A primary wash down will help if there is alot of dirt and grime. I had similar results at first but some trial and error soon ironed this out.
👍👍
Hiya Lee, you would be a fan of hypo, what your doing is correct , just make your mix stronger 50/50 or stronger and leave it no need to swill it down. Cheers Garry. Ps no power washing required. 👍
😁😁👍
Hi Lee,I like to give the patio a good rinse first to get all the mud off otherwise the SH is working through that before it cleans the algae etc,also it keeps working after you’ve finished and when ever you can use hot water,SH need agitation,heat and time👍
Great vids mate👍🍻
You don’t need heat for hypo. It actually will break down the hypo and stop it from working. You always mix it with cold water
I’ve got Indian stone slabs myself and only just found the black spots of mould in them so I’m really pleased I found your video, I’ve jet washed them and now intend to soft wash with the bleach, Great channel mate love your videos 👍🏼
Cheers 👍glad you found us 👊
Don't ever use bleach on Indian sandstone
@@carlbunn8649 why..?
Thank you for sharing the good and bad, it gives everyone a great insight into the product working or not working, instead of just reviews and labels.
😊😊👍👍👍
I have a patio of yellow and reddish coloured 2x2 slabs which become dark grey after a while. I can't pressure wash because there is no drain and I just end up in a big puddle of muddy water! So I just brush the hypo on neat to the dry slabs, and don't wash it off. A little goes a long way. Flow it on don't brush it out. The slabs come up like new. Hypo weakens over time in storage and I've tried to use it 50 50 water , but it doesn't work at all.
👍🙏
Oh dear 😂 Glad to see you’re well mate hope this corona virus doesn’t affect your health or business 👍
😷😷😷👍
Cheer up buddy, good job. We are all learning from dissapointing results not meeting expectations. Plan B will achieve success.
Thank you 🙏
I've been cleaning my patio for yrs and pressure Wash first then use Hypo 3 part water 1 part Hypo, it works every time, the surface us already wet from pressure washing, I add the mixture and brush in, leave for 20 min to 30 min and hose off, DONE
👍👍
I did my drive way, 38 year old pavers, never had a proper wash. I jet washed the muck first, A lot of muck came out, then i brushed in the bleach and left for an hour and then jet washed off . Once it dries it started to look good and a few weeks later it looked even better. . Looking at those slabs you got lichen, that will probably need specialised stuff or a good jet wash after the bleach
👍👍👌
Hi Lee, have used good few times, I mix it 1/3 of watering can to 2/3 water. I honestly think it may be different effects on different stone. I did notice aswell that if it dries at all it's useless. I prefer to do it when it has rained in the morning and the ground is soaked. Best results I got one day is when I put it down went for lunch priced another job so was gone for 2 hours came back and washed it off. Also used a deck scrub brush to really work the harder to clean places. Actually using today on a granite patio. I also found that on mint fossil sandstone it works wonders. Mabe softer stone????? I don't know. 👍. Only found your vids. Fair play and cheers
Thank you ..food for thought..glad you found the vuds👍
Great video as always mate, it’s been a pleasure to watch this as it is to watch all your content 😄 it don’t matter it didn’t work out the way you wanted, we all learn!! I’ve never used that before so wouldn’t have a clue on how to use it, but don’t let it get to you!! I know you take pride in your work mate! Maybe in the future, you may not use it again because of the result it’s given for you, looking forward to the next one😁 look after yourself mate🤘
I pressured washed first, used the solution neat and left for 2 hours, worked great!
👍
I use 10% SH diluted 50/50 with water in a garden sprayer. So pretty strong, but only a fine spray.
Leave it on ie don’t rinse it off, and don’t brush it. No effort at all. It looks pretty good after an hour, and it goes on improving over the following days.
I understand it’s different doing someone elses as it has to look good that day.
🙏👍🏻👍🏻
High pressure clean 1st! Use a detergent to loosen the dirt. Use a surface cleaner. Rinse off. Apply hypo. Surface clean again to remove mould & moss the the hypo has killed, rinse off. Job done. And if you rgoing to persist in using that watering can, put a rose head on it. Youll get better coverage, & use less.
👍👍
👍Amazing video! Great job!!!
Builders merchants buy masonry cleaner clean flags before re pointing use patio cleaning head on pressure wash to remove dirt. use fresh sharp sand to replace wash out from block paving. the patio cleaning head keeps the water from spraying up and will clean most paving with out any cleaning agent.
👍
In the States they usually use the bleach soft wash on vinyl siding and pressure wash brick, concrete and porous surfaces. The UA-camr Dan's Vlog has real good video's on pressure and soft washing.
Thanks 👍
The hypo your using should smell when it's working ,should smell like a swimming pool this means it's working . It should also start to foam . It looks like the hypo your using has gone past its best and lost its strength. I always mix it 2 parts water to 1 part hypo and 50/50 if it's a really dirty job . Hype needs to be between 11/15 % and should be stored in a dark container . Once opened it will start to lose its potency so it's best to use it straight away . Make sure you purchase it from a reputable suppliers as if it's left laying about it goes off and won't work . I apply with a pump sprayer leave for 20 to 30 mins and don't let it dry out . I then jet wash it off . Always wet grass and plants with hose before starting, and give area a light spray so area is damp before applying the hypo. I don't like the smell so I add a pint off fabric conditioner to every mix ( lenor or comfort or use supermarket own brands ) this also helps the mix from drying out to quickly and doesn't bubble up when jet washing . I find it does a great job 👍
Thanks Chris sorry only just seen your comment 👍
You will need the hypo to be 3-6% of your mix. So if you are using normal bleach from the store (6%), use it strait. If you can get 10 to 12% dilute accordingly. Put it on and leave it. It will kill the the organic growth but you may need to use some pressure to remove the dead material.
👌👌👍👍
Strictly speaking using one part and topping up to five is a ratio of four to one or 20%. Also by wetting the surface you are diluting it further, possibly by more than half again so effectively a 10% dilution. The hypo is enough of a wetting agent so adding a detergent is not needed - also it could have ammonia in it which would give off dangerous fumes when mixed with bleach.. After many years the paving adsorbs some stains which become fixed. The best use of hypo is just as paving starts to have a slight green hue or after power washing to kill any remaining algae or moss to delay it from reappearing.
Cheers pal...yes I realised the "mix" when I was editing the video 🙈....not sure the amount spread on the floor would dilute it much but hey... I knew there could be fumes hence the mask 👍..think I need more research before trying again....cheers 👍
Gutted, you work so hard and are so conscientious. I know it will all come well, but it's time and time is money. At least it has had a good soak and the chemicals should help with the jet wash. Sleep well and stay well!
Thank you very much ...yes I've met washed it today just editing the video now 👍..Atb
Decking you can just hypo it but blockpaving and slabs we always pressure wash first
👍👍👌
Hi mate! Pressure wash first then hypo. Remove the dirt and grime and then use the hypo to remove black sopt/ licken/ deeper stains
👍🏻
when using solution i usually use no water mix just lay it down neat youll see the difference
Hi mate us soda crystals is the best way it kills the moss, it is granular just spread over and leave over night then jet wash off it will malt it is what you use in drains . Plus use a bit of hard surface cleaner in the jet washer hope this helps you you are good keep up the good work mate.👍
👍👍
Interesting to see this video. Just pressure washed a customers large patio and they've got some bad black spot so told them about hypo. Never used it myself either, so same learning curve as you. Didnt look much wrong with what you did from the research I've done on it myself. A lot of these pro cleaning lads do go over it with the pressure washer after the first softwash, and then once its been cleaned.
👊👊👌
What percentage strength is your hypo? I use 14/15%. I've been softwashing for few years. I have a standard 4/1 ratio. Spray once, agitate, leave for 15mins, then spray again. Dont wet before spray. You will see it working before you agitate. As it will got white. I never use pressure washer. Will post some videos later. Thanks for great vid.
👍👍
Your commitment is admirable Lee, you never give up I like you try new and different things, we all admire your work and attitude, at least its clean now with your power washing.. 😁
Cheers buddy..just editing power wash video now 👍👍
Hypo sprayed on a presoacked path etc at a 3 parts water 1 part hypo should kill all mold moss algae etc, a good dose of soap added will create good foam so you know where you've brushed, test a few mixes on a friends drive, just make sure its a single one, half hour should easily clean a drive. Saves dirt going everywhere when pressure washing, only drawback for me is lawns etc, can be used on decking aswell but probably about 10 parts water to one hypo and soak decking first and brush gently after 10 mins. You do a lot of good work
Cheers pal 👌👌
Hi Lee. Jim here from J.S.G.S. It's all about making a judgement on how bad the are is. That is to say, the mixture of Hypochlorite. Sometimes I have pre soaked the designated are , then sprayed it and let it to do its work and come another day and power washed it. You have enough wisdom and experience to make a judgement Lee. Regards Jim from J.S.G.S N.IRELAND 👍👍🏡🚛
Cheers mate ...yeah....after varied info i was convinced it was some magical trickery that would do the work for me without power washing..(not that i dont like the power washing)...just thought it would be a quicker route...ALAS 🙈
I normally use household cheap bleach 50/50, go around the day before using a medium stiff brush and a paint roller bucket. Then jet wash next day and point up last.
👍
Might be an old batch of hypo, i put it down neat on damp surface with pump sprayer then agitate with broom like you did. You should see a reaction with dirt/ spores lichen etc
I was thinking that...may look for date stamp 🤔...👌
Also check its 14-15%strength
That black mould is difficult to remove, you need a strong mix ( 50-50 ) and leave it for days to do it's work. Might need a second coat in some problem areas. Don't rinse it just leave , one hour is not long enough for years of black mould build up. I never rinse, just spray in on and leave it and let the rain reactive it and wash it into all the cracks killing all the weeds and seeds, worked for me.
Cheers ...this is where I say advice is conflicting...you say leave it on and it works ....others say rinse it off ...🙈🙈🙈 I'm confused. COM 😁
appreciate you sharing your lessons!
👍🙏
Less chemicals & more Elbow!!!💪
Love your ch Mate!❤👏🌻
👌😊
Great video would love to see more of this stuff and go easy on that coffee it's not good for you🙂
😁😁😁😉
we live in a rainy area and what we use is pure clorox or pool clorox and it eats the bacteria away... it could be the color in the filler you used between the slabs. it also has to be sunny. very sunny.
👍💪
Put it on full strength to start with use your pressure washer after to deep cleaning . Witch you have to take top coat of then what is ever left put 40 to 50 hipo on after and let the weather do the rest . Or just use full hipo over 2 days and leave don’t mix let the full hipo work
I spray hypo on first then pressure wash and spray again brilliant results and lasts along time with it staying clean. Then if you like spray hypo again within about 2-3 months . Saves pressure washing or scrubbing keeps clean to.
Hi mate, I'm a bit late to the video but I use hypo with great results and this is what I've found.
Use the 14/15% stuff. I get mine from alliance.
Never use in direct sunlight as it dries to quick before it gets a chance.
Light hose of area first.
Make a 50:50 bucket up or use neat if area is particularly bad and brush it onto the area you are doing, you will see instant results, white foam will appear in parts as it's doing its job.
Dirt and algae will remove straight away, any green plant material will instantly start dying and will be able to be brushed away in a few days up to a couple of weeks.
Let the product dry in naturally over night and then next day rinse and sweep away. I've had great results time and time again doing it this way.
Cheers pal...yes it was 14/15 and from Alliance 🤔🤔
Your doing your best mate, now you know what that stuff bleach or detergent doesn’t work very well so just pressure wash everything.
👍👍👍👌
Could your client have put a sealer on the blockwork/paving, which I don't think SH will remove.
🤷♂️ not sure buddy
Head up lee! I'm in the same boat and currently have the same views as you! I used it before and while I was doing a pressure washing job... purely to test it out, I did it exactly how you did it!!! And yes it cleaned it a little but it hardly did anything!!
Anyway I'm doing another pressure washing job tomorrow and as I have some left I'm going to try a 50:50 mix and try spraying it on rather than watering can just to experiment. Happy to let you know how it goes if you're interested!
Yep keep me posted mate...I've pressure washed it today and all is well now 👍
@@LHLgardenservices I've messaged you on Instagram mate
There should have been a better result so something has went wrong. Few things could be 1) is the hypo fresh? Old Hypo will lose strength and throw out your ratio
2) what strength is the hypo? 5:1 ratio is based on 15% hypo. If you have bought 10% obviously that will be weaker.
3) hypo is a aid to cleaning ground surfaces and very rarely the sole method needed to clean. You can apply before or after pressure washing (personally I prefer before). It will always need time to work and rinsed off at the end.
Cheers ..im thinking hypo was stored too long 🤷♂️
Thats chronic you done such a good job and just look at it, oh my...
A bloke at work was telling me he had used sodium hypochlorite on his drive and was telling me how good it was, after a couple of years he moved house and brought me 5L that he had left over and didn't need. I tried it on my driveway that weekend and found it completely useless and after a bit of googling found that it degrades to salt water over time! Maybe this is your problem?
Possible buddy 👍
You need to use a hot pressure washer before applying the chemical.
You have a wonderful UA-cam channel. You’re a fantastic landscaper gardener as your videos show.
Keep Calm & Carry On.
😂😂😉😉
Good of you to show this, I'm using Hypo for the first time shortly so found this very helpful, have you got a link for that all in one mask please, thanks in advance
Cheers ..Ill sort out the link 👍
I tried 5:1 first the same as you. I to was very disappointed. So I tried a 50:50 mix and couldnt believe the results. As quick as I was putting it down (with bucket and brush) it was changing in front of my eyes. From black to clean sand stone slabs. I found with the stronger mix you could see it turn white where it was really attacking it, so if it's not doing this I suggest it's not strong enough.
Also getting any loose dirt/mud off first will always help the chemical get to what it needs to also
Yes I agree ....50 / 50 next time 👍👍👍
You pressure wash first then apply sodium hypochlorite for 2 hours then again pressure. Left the pointing to last. Darren from salix gardening
👍
Think I will stick to my pressure washer, cheers for sharing Lee
👍😁😁😉
Good fella top video.
Thank you buddy 👍
I find that pressure washing patios tends to wash out the joints. I use Thin Bleach from the supermarket diluted 50:50 brings back the finish. Applied with a rose watering can. I don't wash it off. Just leave it.
👍
No doubt you worked hard , ive just used hypochlorite on a badly marked path what i did was pour approx 50\50 water and hypo and brush it on with soft brush leae there for about 45mins then wash off with hose it worked well but maybe its different on different stone etc.Well done anyway hope it all works out in future.
🙏👍
Hypo ie bleach will lift grease/ fats etc to the surface. Definitelyneed high pressure rinse water to remove once chemicals have had the contact time
👍👍👌
Like you say there’s lots of conflicting stuff on it. I’ve always been under impression from what I’ve seen & heard that one pressure washes first then hypo and the hypo job is more for black spot? That’s how I found out about it wondering how to remove black spot. Not tried it though client wasn’t keen as worried about her dog. I’ve used household bleach diluted in past on white rendered walls prior to washing the algae off and it’s cleaned it before I’ve even touched it with the washer. So Hypo will have some effect on the clean even if just helps slow down re-growth 👍🏼
👍👍
maybe your bleach was from an old stock, it does weaken with age, i did my sandstone during lockdown & it came up like new...obviously it’s meant for cleaning lichen & other growths rather than dirt so, a low pressure pre clean may have helped followed by a stronger mix also, you can use a bio-cleaning product that, in effect, consumes the growths...great learning curve so 10 out of 10, mate.
👍👍
Hello lee
Hypo dose work.
i do half hypo half water....sometimes you might need the jetwash aswell.
Cheers pal 👍👍
That was a very interesting video mate , I can’t wait for your return with a pressure washer for a comparison . Don’t beat yourself up . 😊
Very kind thank you ...editing video as we speak 👌👌
Dampen down the surface and apply the Hypo. Let it sit for 10 mins and agitate it with a stiff brush. then pressure clean it with a patio head so it doesnt kick all the crap everywhere. Then rinse off afterwards and repeat if you need to.
👍👌
Well done for showing the days when it's one monumental arse up after another! They're just as important, so keep fighting mate....🤣👊👊
Cheers ..no problem mate ...ill never get too big for my boots 👌😁
You 100% need a decent pressure washer & a flat surface cleaner, works for me everytime 👍
👍🏻
Just using chemicals is not good, regardless of how it cleans it is all getting, albeit diluted, into the ground and drains, not good for a garden path that in a few weeks will be getting dirty again. A good pressure washer with decent PSI and high flow rate will get the job done with no harmful chemicals. Sure you will get it looking all good though, always turns out great in all your other videos.
👍👍😁
Very disappointing for you Lee I'm sure, but I'm also very sure you'll win the battle. Great honest video (the highs & the lows) 👍
Thank you ..sorry only just seen this comment 👍👍
Add the hypo to a wet surface, leave it to work for a bit, then power wash it off. It should make the power wash lift the dirt a lot easier
👍👌👌
How old is the hypo mate. It reduces chlorine in heat and time check when it was batch . I worked in swimming pools for 25 years and used it all the time but it does go off
Yes think I had it in my unit fir a month or two👍
Jet wash first then use the hypo on areas that need it. You need to lightly jetwash the surface first to get rid of general surface grime. Then the hypo will hit the spots that need it.
Cheers bud 👍
Well....this appears to be the kind of day that a man would want to rend his garments, smear ashes on his forehead , curse any handy local deity while wearing copper underwear in a thunderstorm. And YOU say "I'm not happy." Wow. Fortitude. I am impressed.
😆😆sorry only just seen your comment
Light hose water down concrete first - Degreaser mixed with bleach or chlorine sprayed onto concrete - let it dwell for 10 minutes - pressure wash off with surface cleaner. Never fails me.
what went wrong? too dilute
As for removing surface dirt first, that comes down to a commercial decision, may mean you end up pressure washing before and after the soft wash. As a homeowner I'd do that at home, for commercial purposes I would not.
👌👌👍
Hi Lee did you buy one that was all ready diluted? And to be honest like you said its a bleaching agent not a cleaner. And is nor. Ally used for removing white and black spots of paving
No it wasn't already diluted...my brain was diluted after this job 🙈😂
