This took me back to 1954 when I was working on Devonshire House on Piccadilly. Rootes showrooms. Remember Lord and Lady Docker? The ceilings had been fitted with heating panels. Covered with Expanded Metal (mesh) then plastered with course stuff. Lime putty, sand and beaten cow hair. I slaked the lime using a larry. It was a D shaped hoe. I doubt you could buy a larry nowadays. No respirators in those days and I'm still here. I teased out the cow hair by beating it with battens on a layer of mesh. -The ceiling was then covered with a layer of hessian and 'skimmed', finished with putty and plaster of Paris. Days of old when Knights were bold eh? Keep up with the great and interesting videos, Kris
This is great! I have used lime putty myself. Beware that 1 volume of putty is equivalent to more than 1 volume of powder, so you need to adjust your sand:lime ratio accordingly. 3:1 is way too strong and will suffer from shrinkage, in case you didn't know this. It is nothing like NHL. 4:1 should be the a absolute strongest, and weaker than that is probably much better. This is from my experience and an old book of lime mortar experiments. One note about plaster: I would expect it to crack-up if it doesn't have hair in it, but your final finishing coat (thin) can have a fine aggregate and no hair.
Hi Kris, having watched you from your eco fledgling days , you have the determination and environmental awareness required to create a harmonic place where you feel happy to live and I enjoy your projects , just be careful with that stuff , ive been using it and lots of other lime based materials for over 40 years , quicklime is the one to respect , once slaked no problem it can burn a bit but your skin gets used to it after a while and doesn't bother you again, after 47 years doing it for other people I am now building my own eco dwelling straw bales & lime plaster walls all roundwood timber structure from locally harvested trees { striping bark is a hard work lol } also oak hand split shakes on the roof { only 8500 to make Ahhhh} im forging all the door furniture myself etc etc etc , solar wind & hydro powered , I live in wiltshire and I managed to get permission { took years lots of plans & paperwork phew } to build this in a feild in the countryside how kool is that mainland uk being eco aware , I think I either had a likeminded planning officer or I wore him down by not giving up lol , PS , by the way it is cheaper to slake your own but I use mike wye its £ 11.50 plus vat for 20kg buckets mature lime putty we use it a lot in my business , all the best
Thanks for taking the time to comment. it sounds like you have a big project ahead of you. i wish you all the best with that. more of use need to get to self building with natural materials. Thanks for the advice. kris
Hello Cattelona Chanced on this video and your comment today 13Jun2022. I'm deeply interested in earth houses and plan to build one for myself.. using freshly slaked (and matured 28+ days) lime putty in the earth-bricks, in the cob, in the plaster etc. I'm sure by now you have completed the big project you mentioned. Is there a video or a writeup with pics we can refer? If yes, pls share. Thanks, and best wishes. Rajeev Agarwal, India
Good to know! I'm trying to calculate how much putty to mix up for my house... any idea of what volume of aged lime putty to expect from a given weight of quicklime?
@@noahelhardt5589 hard to remember now...but I think I used 2x20kg quicklime (CaO)plus water...mixed in a 55 gallon barrel.(Take all safety precautions, including a mask that filters vapour....you do not want that extremely strong alkali in your lungs) It gave me at least 8 (10?) x 5 gallon buckets of lime putty. I still have 6 left after making paint and lime render for the interior and exterior of a 20 foot diameter mud hut. Every now and again I check on the putty and top up with water if necessary...it will keep forever as long at it has a water cap and is sealed in an airtight container. The lime particles keep dividing over time,( slight expansion) resulting in a finer, stronger putty. Best of luck with your project.
I have an extra reusable respirator(5500-30L). It's a year old and have seen about 3 hours of use. You're more than welcome to have it. Do you have a PO box?
Typed in 'lime slaking' and your film popped up Kris. Always interesting to see how other folks do their work but your end result looked too watery and having too much water weakens a mix which usually results in lots of cracking and not as effective in binding together. After my slaking there's no water on the surface, just the putty. The bags of stuff you used has a lot more dust and also costs more than my stuff. I buy 18 Kb bags of Singleton Birch for £9 a bag, the plastic tubs (re-used multiple times) of chalk lime putty cost £9.40. I use a 2 & 1/2 sharp sand, half a builders sand and 1 putty mix which covers about a square metre. For the slaking I do 2 buckets of water to 1 bag of quicklime getting 2 tubs of putty for a bag of the fine kibbled quicklime. Using a sharp blade I slice the 2 plastic bags (re-used multiple times) and upend the contents into the water, which starts to react within a couple of minutes, not using gloves or goggles (which is recommended) I reach for my plasterers whisk and give the contents a good turn over and put a plastic mat over the top of the bin to stop it splashing everywhere, after a slake I scrape off about 3 trowel worth of product. Within 4-5 minutes it's bubbling and frothing in a rising crescendo until it's like boiling mud. After the action subsides I put in the whisk and turn the whole thing over again and leave it to sit while I get the tubs. Fill 4 tubs with the putty which has thickened up more like clotted cream and leave to stand without a lid for 20 hours, by this time you could turn the tub and it would stay in the container. I still have 2 tubs of lime putty from 2001 which is like a solid cheese, you could cut out a slice like cake. I once heard about some 500 year old putty found in some Italian pits which was still very usable. There is less waste using putty mortars over cement, and uses less energy to produce than cement. A lime mortar absorbs carbon dioxide and gives a room better acoustics. I normally make my mortar a week before a job but you can use the mortar the same day if you want, left for longer it amalgamates & makes a stickier mix which stays on your trowel when you turn it over. As you said you can do a hot-mix with it which is just right for rubble-stone wall work because it expands in the joint and in the old days before cars they would take the lump-lime/quick-lime with them and slake it in pits dug in the ground at the job. For the really grand jobs there were travelling families of Italians that specialised in the ornate fibrous work and running I've worked with lime since about 1999 and have been working ever since since I specialised, I rarely use hydraulic or hydrated because it would cost me more and there would be more packaging rubbish. Just like to wish you all the best in your work.
THANK GOD FOR YOU MAN, legit i was pouring 300 grams into a 55 gallon water barrel and then some like slipt off the cup i was pooring it in and made a little cloud i like got the tiniest cloud specs all over me and inhailed the tiniest bit ( this was all done outside) and my brother conviced me it was going to super fuck me up lol
Maybe you already saw it, but Guédelon's channel (The castle being built in France using experimental archeology) did a 5 episodes series on quicklime making called "Les feux de Guédelon", I guessed you'd be interested in watching it !
Just looked up what happening (chemical reaction) via google: Quicklime (Calcium Oxide) reacts with water in an extremely heat-producing reaction, a process called "slaking". ... Once Calcium Hydroxide is exposed to air (whether it's in powder or putty form), the lime reacts with Carbon Dioxide in the air and ends up where it started...as Calcium Carbonate.
Perhaps you can smell it because your smeller is limed away. Good job on all you do, I never miss an episode. I would love to see some companies pony up and sponsor your projects.
About a respirator. . . I work in a steel mill and we use a full train car every few days so there is plenty around. The best thing we've found if we're doing lots of work on the system is to use a PAPR (positive air pressure respirator) Not sure how much you'll be working with the stuff but if you do a lot more you may look up a PAPR and give it a shot, much easier to breeth in than quarter face resps and covers the whole head. Could probably just make one to be honest
@@bushratbeachbum We use it for slag. Dump a bunch in the furnace and it creates a blanket over the steel bath, protecting it from oxygen/impurities and keeping some heat in. The majority gets poured off before we tap but we also do the same in the ladles, for the same reason
what if you pre cut the bags (I mean cutting the tiops clean off so no dusty swinging around of the bag is required) and then tip them over in the tote, holding the cut end slightly under water??? Keeps the dust down at least...
Will you need to keep the water buffer topped off due to evaporation? Also apparently some plastics still let gasses through but VERY slowly, so that might be something to watch out for in the long term I suppose
If you want to financially support this channel, remember not to skip the adds - I think this generates revenue for the channel holder, but only if the add completes
DukeOfChirk - That is also my understanding, which is why I let most ads play -- with the volume off. This provides revenue to the channel while I do something else for the duration of ads over 30 seconds.
Is also my understanding that if you sub to yt premium (or whatever it's called) channel holders get even slightly more and can miss the ads altogether :)
As quicklime is not readily available in the US, we use bagged hydrated lime - mixed with water - which works well, especially with metakaolin. As all the old world traditionalists use putty, it must be better, but I have not idea how or why it is better. Thanks!
Awesome Video as always Cris. I have an IBC container but am guessing the walls would be too thin for the heat. Do you have experience with that? All the best!
That statement assumes respirators are superior dust blockers and that you know more about safety in general and thus job in specific, all at once. Your common/robotic use of passive-aggressive, ignorant (truest sense) directives of advice may be cloaked with good intentions, but since this skilled workperson is in fact wearing a FAR superior device for dust filtration than your $40, carbon-activated band-aid, and yet you assume a lack of thought or safety, you might look into your own knowledge of when to give advice, what it might actually look like when you do, what is safety in general, and whether you are confusing safety with normalcy and new, plastic parts. There's a lot of telling other people to be 'safe' without much premeditation, on the surface it is a blind enforcement of normalcy, and is of political use. $2-200 masks can be great for looking safe in public and personal merit-badging, can filter out a lot of dust for two solid minutes before voiding the warranty and attempting to wash, are great for a few hours or minutes of harmful vapors, cause bacterial growth in the lungs over time when not changed out every few days, go bad in a few weeks after opening from package, etc...
@@readoryx373 That’s a whole lot to write when my comment was about Kris not using anything but a cloth. I guess stating you’re a “skilled workperson” is supposed to add believability to your comment too I guess without you knowing or me stating what my knowledge or skill level is. One counter point I have is that not all respirators are carbon activated. Some are actually dust filters but don’t let facts ruin your “great” comment. Kris mentioned respirator so that’s what I commented on. Bottom line is any dust filter is better than what he used and you don’t want that dust in your lungs.
Hey Kris, absolutely love your videos man and a huge supporter of what you’re doing here. So much so, In fact, that I’m seriously considering giving building an off grid house a go myself. Just wondering how you dealt with planning - I also live and would be building in wales. Many thanks!
This whole time I thought he was making hydrated lime to amend his garden soil. lol. It could probably still be used to help Tomatoes if the soil is too acidic. The main cause of blossom end rot.
Looking great Kris. Certainly a lot easier and time effective than kilning the limestone. Do you rely on the water evaporating over the 6 months or does it keep absorbing it to make it a thicker mix? Thanks again for your videos!
doesn’t it get hard and very compacted at the bottom? how? I tried a few times myself, and some of the times... with the very same lime... it got creamy and nice to work with, but twice it got very concentrated at the bottom, almost like a rock, and it isn’t a hydraulic lime 🤔
I’m hoping to do the same thing soon. I’m in the US. And it has taken me quite a while to find a place that actually has bags of calcium oxide. I’m planning on mixing mine up in a steel drum and then transfer to smaller containers for storage. I guess after a while you start to understand what’s going on with the mix. I am guessing you see the reaction of quick lime in water subside and then add enough water to cap off? I’m assuming a couple inches is enough?
Hi, Yeah you got it. just keep adding cold water until it settles and stops reacting and then leave an inch or two of water on top. it will settle down a bit as it compacts.
I'm in northern Arizona and it took me 3 months of searching, calling, emailing, ... Couldn't get any local business to special order. The local Lhoist mine strung me along for weeks. Couldn't have felt any smaller. Finally ordered 2 tons from Tacoma WA, 2 trips to Las Vegas in my 23-year-old truck, the stress! Now I need to figure out how to slake some of it, but might hot mix for a floor. So many projects, so little time!
@@andrewsackville-west1609 Thanks for reminding me to finally get the info online: highdesertpermaculture.org/2023/09/27/sourcing-quicklime-and-lime-putty-in-the-us-southwest/
Do you have any insight into how the hydrated lime is made into the powder form that us common folk get in the bags at the garden center? I havent watched till the end yet so maube you're going to answer my question anyways.
As a chemist that sound 5:30 makes me hella nervous. the same thing happens sometimes dissolving caustic soda, it can be really dangerous if it starts boiling as it can throw the boiling corrosive mixture at you.
Yes, much safer, this process is turning quicklime into hydrated lime, so if you start with hydrated lime you are just dissolving it rather than making tons of heat, also hydrated lime is less egregiously dangerous to your flesh
just out of curiosity, What are the pro's and con's to using lame rather than concrete? does it cost less? only reason I ask is, it seems like if your going to go to all the trouble to get all those bags and cut them all open and mix an whatnot it seems like your adding extra work for yourself. IDK maybe I missed something in a previous video.
The layer of water on top stop carbon dioxide getting to it. it does not need stiring. it will go like cream cheese and it is used like that. it will store like this indefinitely
Kris no hablo inglés. No se q has dicho. Pero para la próxima ves q apagues cal hacelo en un tacho abierto no semi cerrado. Q alguien vacie las bolsas de cal de a poco y otro bata o renueva sin parar . Al estar abierto de forma total el tacho los gases se disipan mejor y más remuevas mejor es. La cal apagada a las 24 ha siguientes debe quedar como una crema espesa q queda con la forma al sacar con una pala y no cae de la pala. No debe quedar grumosa ni como muestras floja q se cae.. ojo quizás todavía no la habías dejado estacionar por eso no quedo espesa. Espero no ofendert. Saludos
Translated via Google Translate (Traducido a través de Google Translate): "Kris does not speak English. I do not know what you said. But for the next time you turn off lime do it in an open not semi closed. Q Someone empty the lime bags a little and another gown or renew without stopping. By being completely open the tank the gases dissipate better and the more you remove the better it is. The slaked lime at the next 24 ha should be like a thick cream that remains with the shape when removing with a shovel and does not fall from the shovel. It should not be lumpy or loose signs that fall ... eye maybe you still have not let it park so it is not thick. I hope no offense. regards"
Nice one Kris, keep those video's churning out. our date is getting closer for the big move :) really hope i can get down to see you again before we go. say hi to Dot for me, hope you have warm feet :)

Slaking quicklime to putty is a dangerous waste of money. Thats the point of hydrated lime, its been partially hydrated to prevent a violent reaction at first but the end product will be identical when making putty. Quicklime is for hot mixed mortars to be used there and then or soured for later use but always mixed with sand. And there is no need to even make putties it was to break down weak, overburnt or badly ground lime for plasters where blowouts can be a problem. Todays quicklime is pure and perfectly ground and sieved, the jobs been done. No good reason to do this at all, sorry.
I remember seeing a video of a Scot making lime wash direct from quicklime and adding lard to it. The lard melted with the exothermic reaction and made the resultant wash more waterproof, or at least that was the claim, perhaps it forms some sort of emulsion?? Might be one to experiment with in the rainy West. Not for plaster of course, but as a final external wash for rendering and stonework, if you've just slaughtered a fat pig and have lard to spare...
It's possible that the quicklime-water mixture was so alkaline that some of the lard was turned into soap. The soap would be able to emulsify some of the remaining fat.
If you are working outdoors you don't need a fucking respirator, I mixed hundreds and hundreds of tons of that as a young man and as a kid I used to love going down to the puddling sheds and watching it bring done and the one part of my body that is fine is my lungs. Mind you, you do tend to do in a way that makes life difficult for yourself.

Hey Kris, absolutely love your videos man and a huge supporter of what you’re doing here. So much so, In fact, that I’m seriously considering giving building an off grid house a go myself. Just wondering how you dealt with planning - I also live and would be building in wales. Many thanks!
He didn't.
I believe those bags are made so you can pull the top off in one go.. no need for either a knife of those scissors 😀
This whole time I thought he was making hydrated lime to amend his garden soil. lol. It could probably still be used to help Tomatoes if the soil is too acidic. The main cause of blossom end rot.
Use OMRI listed (organic) gypsum for gardening.
Wow, that chemical reaction is fast and furious!
Well done!
Looking great Kris. Certainly a lot easier and time effective than kilning the limestone. Do you rely on the water evaporating over the 6 months or does it keep absorbing it to make it a thicker mix?
Thanks again for your videos!
The pudgy settles, leaving clear water on top. This allow enough to be pumped away, that you need to add water to the mortar mix.
doesn’t it get hard and very compacted at the bottom? how? I tried a few times myself, and some of the times... with the very same lime... it got creamy and nice to work with, but twice it got very concentrated at the bottom, almost like a rock, and it isn’t a hydraulic lime 🤔
Hi Kris, what should be the size of container for slaking a metic ton of quick lime ?
Cool cool 11:24 i made some i think, it had this crust sounds like ice when you swish it.
Use to work in a state that made working with lime illegal because bricklayers noses were falling off
Anyone else hold their breath at 8:40? 😂
I’m hoping to do the same thing soon. I’m in the US. And it has taken me quite a while to find a place that actually has bags of calcium oxide. I’m planning on mixing mine up in a steel drum and then transfer to smaller containers for storage. I guess after a while you start to understand what’s going on with the mix. I am guessing you see the reaction of quick lime in water subside and then add enough water to cap off? I’m assuming a couple inches is enough?
Hi, Yeah you got it. just keep adding cold water until it settles and stops reacting and then leave an inch or two of water on top. it will settle down a bit as it compacts.
Did you find a source of quick lime?
I'm in northern Arizona and it took me 3 months of searching, calling, emailing, ... Couldn't get any local business to special order. The local Lhoist mine strung me along for weeks. Couldn't have felt any smaller.
Finally ordered 2 tons from Tacoma WA, 2 trips to Las Vegas in my 23-year-old truck, the stress!
Now I need to figure out how to slake some of it, but might hot mix for a floor. So many projects, so little time!
@@christinebaker3293hi. Who did you order quicklime from? It's hard to find!
@@andrewsackville-west1609 Thanks for reminding me to finally get the info online:

Do you have any insight into how the hydrated lime is made into the powder form that us common folk get in the bags at the garden center? I havent watched till the end yet so maube you're going to answer my question anyways.
As a chemist that sound 5:30 makes me hella nervous. the same thing happens sometimes dissolving caustic soda, it can be really dangerous if it starts boiling as it can throw the boiling corrosive mixture at you.
Amazon has sweet looking respirators that covers the whole face $30 or less
In America everything is a lot cheaper.
OUTSTANDING !! 👍🍻
Very Interesting . 6 months for a finished product you say?
if quicklime wasn't available could hydrated lime be used in its place and would it work as good?
Yes, much safer, this process is turning quicklime into hydrated lime, so if you start with hydrated lime you are just dissolving it rather than making tons of heat, also hydrated lime is less egregiously dangerous to your flesh
just out of curiosity, What are the pro's and con's to using lame rather than concrete? does it cost less? only reason I ask is, it seems like if your going to go to all the trouble to get all those bags and cut them all open and mix an whatnot it seems like your adding extra work for yourself. IDK maybe I missed something in a previous video.
Yea, breathing is hard to do, in a mask 👍🏻🤯 never saw white wash made before. Way cool
Can quicklime be slaked for Venetian plastered with marble dust added etc ?
How can we use quick lime for bricks laying mortar?lime putty +sand or clay for mortar??
hi kris how much did you get your quick lime for a bag, and is there a video on using the putty after it steeped, cheers
should have built a hopper , filled it and then opened it and think of the fun that would be!
The putty won't solidify over time? How are you going to stir it when you'll use it?
The layer of water on top stop carbon dioxide getting to it. it does not need stiring. it will go like cream cheese and it is used like that. it will store like this indefinitely
Cement mixer he said wen he is ready to use it
is the quicklime caustic or the slaked lime (or both)? Thanks!
Just wondering why you don't mix the Calbux directly with sand as and when you need a mix. Or mix with sand and stock pile the mortar?
Do I understand correctly that one does not want to let the putty be subjected to freezing temperatures?
Tried pickling eggs in slaked lime? I kept eggs for 9 months during the lockdowns.
put a tarp over it while your pouring then you can lift a corner up and pour under it.
I was under the imprssion that you had to use hydrated lime for lime putty mortars. and not quick lime.
You want Calcium Hydroxide---- you want to make it into plaster asap so when it turns to CaCo2 it sets
Would a sand clay mix not have been cheaper/ easier ? The method another channel you have mentioned uses ?
Nigel copsy says you should not add lime to water. But water to lime.
Whats cost per bag?, curious cant find in USA in quantity.
I ended up ordering a couple tons because shipping got cheaper. Couldn't source in the southwest, had to ship from Tacoma WA.
Kris no hablo inglés. No se q has dicho. Pero para la próxima ves q apagues cal hacelo en un tacho abierto no semi cerrado. Q alguien vacie las bolsas de cal de a poco y otro bata o renueva sin parar . Al estar abierto de forma total el tacho los gases se disipan mejor y más remuevas mejor es. La cal apagada a las 24 ha siguientes debe quedar como una crema espesa q queda con la forma al sacar con una pala y no cae de la pala. No debe quedar grumosa ni como muestras floja q se cae.. ojo quizás todavía no la habías dejado estacionar por eso no quedo espesa. Espero no ofendert. Saludos
Translated via Google Translate (Traducido a través de Google Translate):
"Kris does not speak English. I do not know what you said. But for the next time you turn off lime do it in an open not semi closed. Q Someone empty the lime bags a little and another gown or renew without stopping. By being completely open the tank the gases dissipate better and the more you remove the better it is. The slaked lime at the next 24 ha should be like a thick cream that remains with the shape when removing with a shovel and does not fall from the shovel. It should not be lumpy or loose signs that fall ... eye maybe you still have not let it park so it is not thick. I hope no offense. regards"
@@brawn00 muchas gracias por traducirme.
someone would think you are mixing cocaine lol Narco Kris “aye say helluuu to mi lil friend” lol
hi. lime putty = quick lime + water?
I feel sorry for the camera man, he got it right in the mush.
Tripod
I don’t care what his name was, he was still in the wrong place.
@@mikehales6892 for real
Oh dear seems like I have to explain, Its a British thing called sarcasm, of course I know that the camera is remote, mounted on a tripod.
❤❤❤
You look like one of the minions from Despicable Me .
I thought he looked like the invisible man, I had a little giggle ....
6 months , jesus.
I am surprised you didn’t melt your plastic tank😂
Do I see a new way to heat he solar shower?
What kind of academic degree do you have Kris? Or are you just insanely intuitive about how things go together?
I was thinking for 10 minutes, does this man really need literally a ton of slaked lime powder??!!! HOW MUCH BEETLE NUTS IS HE TRYING TO EAT!
👍😍
Nice one Kris, keep those video's churning out. our date is getting closer for the big move :) really hope i can get down to see you again before we go. say hi to Dot for me, hope you have warm feet :)
Would having the shirt wet help to catch the powder before reaching your lungs?
News Binge Aye, moisture and lime isn’t something you want mixing on your face.
Better there than in your throat or lungs though, right?
Lives in a house in the middle of the woods, has a highly intelligent cat, makes magical things, and a smouldering cauldron, Kris is a happy, friendly witch.
Holy shit, this video is terrifying >
row row row the tote...
In our day we used our bare hands and my prick to stir it
Slaking quicklime to putty is a dangerous waste of money. Thats the point of hydrated lime, its been partially hydrated to prevent a violent reaction at first but the end product will be identical when making putty. Quicklime is for hot mixed mortars to be used there and then or soured for later use but always mixed with sand. And there is no need to even make putties it was to break down weak, overburnt or badly ground lime for plasters where blowouts can be a problem. Todays quicklime is pure and perfectly ground and sieved, the jobs been done. No good reason to do this at all, sorry.
I hope your lungs are okay. I wish I had easy access to quality lime like that in the states.
Home Depot carries calcium carbonate, got to dig around and read SDS sheets
@@davidwilkins1671 Not recommended. Type S is very hard and processed.
This like how the Romans did it.
I remember seeing a video of a Scot making lime wash direct from quicklime and adding lard to it. The lard melted with the exothermic reaction and made the resultant wash more waterproof, or at least that was the claim, perhaps it forms some sort of emulsion?? Might be one to experiment with in the rainy West. Not for plaster of course, but as a final external wash for rendering and stonework, if you've just slaughtered a fat pig and have lard to spare...
It's possible that the quicklime-water mixture was so alkaline that some of the lard was turned into soap. The soap would be able to emulsify some of the remaining fat.
Get a respirator 😂
Go Cornish, whole ton £280 in 2022. 4 months guaranteed
👍👌👏 Simply fantastic. But please be more careful with your health.
Best regards luck health and wisdom.
I am not kidding,l swear I could smell the reaction while holding my breath.please get a face mask.
your a mess sod hahahha but good on ya
If you are working outdoors you don't need a fucking respirator, I mixed hundreds and hundreds of tons of that as a young man and as a kid I used to love going down to the puddling sheds and watching it bring done and the one part of my body that is fine is my lungs. Mind you, you do tend to do in a way that makes life difficult for yourself.
Buy your self a respirator be safe not sorry!!!
For God's sake man, go buy a knife.
