Your plaster is perfect for pumicecrete walls Pumicecrete is by far the best building material on the planet Pumicecrete is a mixture of pumice cement and water mixed and poured into a set of reusable forms walls are poured from 12"to 24" thick pumicecrete is fireproof termite proof rust rot and mold proof and has a high R value and good sound attenuation solid poured walls means no critters can live in your walls Pumicecrete can be built for a fraction of the cost and time and pumice is one of the few building materials that can go directly from the mine to the job site ready to use without any additional possessing and zero waste Google all the walls of my house are made of pumicecrete
You got sold a bunch of BS. Pumice is just and aggregate and every other aggregate goes quarry to site with the same processing. Some chemical reaction with the cement and low R value. Moisture transfer needs to be addressed also. A sandwich wall with aluminum foil faced rigid foam is superior in every way.
@raymondpeters9186 R value under .50. Also, it can't deal with wet areas that also freeze, that'll turn it to dust. There are a lot of better systems out there to choose from.
same, the amount of info online and is sometimes contradicting. My wife inherited an old family house, stone built, over a hundred years old, the house is fine but we leveled out a piece of land for a car park and built a wall around it for the garden to butt up against. in one of the storerooms I found 120kilos of powdered lime, so I'm looking into plastering the wall with that from the start.
I want to plaster an exterior wall with lime that takes on ALOT of rain. The cement stucco is over compote, styroform sheets for insulation. There are cracks all in the cement stucco and it was just done in 2021. The inside of the wall is cement stucco so I won't the get the breathability but I will get the water protection. Great video. Thank you.
Thanks for the excellent video. What about cracking due to temperature and humidity variations? I am in zone five, we get very cold and hot / humid. Is there a maximum distance that should be divided by a control joint? Old European buildings with stucco always seem to be broken up into segments.
Lime plaster is amazing stuff…who wouldn’t want their home encased in limestone?!! We are building with like here in SE AZ and are using it on our hyperadobe builds. Great video and info!
So interesting!! I've heard alot about lime plaster from Robert Crabtree's videos. Probably going to parge my basement walls with this stuff. Still in the education process. Thanks so much for your helpful info!! 🙂
Wow! I am super inpressed I live in the East Texas Region is there a difference for this type of climate and what kind of strae bails can I use here.I want to buikd my nest House this way for sure.
Question..... what is your experience in using “lime putty”, sand and water on rock retaining walls and rock built walls of old buildings? Would using a clay sand, straw or rice-hull mix base be better for insulation, a surface to build plaster putty on along with the insulative and breathability qualities?
We have loads of old rock-built cottages in Britain which were plastered inside and rendered outside in lime. If you want to protect the outside, but keep the rock look, you can do what is called a "bagged finish", where you slop the render up, and instead of trowelling, they used to use old sacks to rub the finish down. It ends up showing the shape of the wall underneath. Just search for "lime bagged finish" and you'll see what I mean.
thank you so much for this great video! what would happen if i just mix ground limestone and water (without the sand). could i spread that on the surface of the walls of my house as a textured "finish"? or is that a bad idea? i'm looking for a natural "white" wash textured-finish. thank you!
Question I have a 1970 barn that I’m turning into my home it has shiplap siding, but the inside is not finished yet all open to siding inside no housewrap What would you do? I feel like taking it off. Could break a lot of the wood. It’s a cedar barn.
Hey speaking of "Carbon Neutral".... by any chance have you heard or thought about Bio- Char as an aggregate? I read a great book about using this material in various ways called -Burn-, Using fire to cool the earth- One of the studies covered the use of Bio-Char in concrete mixtures. Astounding strengths have been achieved apparently. The book emphasized the notion that besides use as an incredibly valuable soil amendment a multiple "cascading" approach to its use including as an aggregate would encourage greater use. For example keeping track of all the material first used as filtration which is presumably discarded after conventional applications finding its way into building mode instead.
Love it! We bought a property 2 years ago and we have a two floor - cement based - mid. '80 house and now I had an idea... Can cement based (non organic wall) be covered with lime coat? Great video, thanks.
You may want to look into bonding agents that will help the lime adhere to the cement stucco. Or mix a little cement in with the first coat of lime (like bonds to like) 👍
@@HeirloomBuilders Wow! You just saved me a bunch of time and research- or more accurately, pointed me in the right research direction. I'm doing aircrete domes, and I wasn't satisfied with the stucco top coat idea. Many thanks!
I like your presentation. I am building a new home with Perfect Block ICCF and am looking for a lost cost way to give the board and batten look. (Wife is set on Modern farmhouse). Steel siding is way out of this world in price, vinyl (will never use anyway) isn't that much cheaper than steel ( material cost). I am thinking maybe I can create a smooth surface with lime plaster and add some sort of battens?? Any thoughts, anyone? Also, how is the paintability of the lime plaster being that the breathable aspect is not a concern here?
Don't do the ICF if you haven't yet. Concrete forms are cheap to rent and a sandwich panel wall using Thermomass is some much better and cheaper. Save a bit more by putting the electric in the floors instead of walls. More expensive outlets but they're much nicer if you get deep ones that plugs go inside. ICF is bordering on a fraud being sold to people that don't have much construction knowledge.

Sorry ... one more question :-) When I talk to people about the type of sand I need for hydrated lime there seems to be a lot of confusion out there. I called the local Mason supply company here in Portland, Oregon and they weren't sure what kind of sand should be used with hydrated lime. They have all different kinds of sand ... just weren't willing to tell me which is best. Also it comes in bags which is very expensive. I can pick up a pickup load of masons sand at my local landscaping supply company. Do you think that could work? Any input you may have on this subject would be much appreciated!
@@HeirloomBuilders : happen to know that beach sand is more rounded, mason's sand is more angular. Something more like crushed gravel as opposed to regular rounded river gravel.
@@garywheeler7039you are rite beach sand is more rounded AND like mentioned above has salt that destroys walls, however another real reason to use masons sand is the angular cut of the sand lock in against each other preventing movement and slippage whereas particulates of rounded sand will move and slip n slide around each other ! Visualize smashing a case of bottles up into pea size pieces and putting them in a bucket, then try pushing a stick to the bottom of the bucket. The stick won't penetrate the glass because of the jagged edges locking together. If you fill bucket with round marbles the stick will slip thru the marbles all the way to the bottom of the bucket, same exact thing with round sand !

Hey! Not sure if you would know, but would it work to have the outer layer of a straw house be made out of brick? I am wondering what the logistics of building a house like this in an area with heavy snow as well as monsoon seasons. I think that the insulation and fire resistance of straw bale homes would be perfect where I live, but water resistance is very important as is pest prevention, and I'm wondering if even a brick wainscotting would help? Or would it stifle the natural breathing process of the house? To my understanding brick breathes pretty well.
Type S or Type N hydrated Lime? I am in Southern California and have had a hard time finding any type N hydrated lime only type s locally. I thought type N is better for any load bearing applications so I assume type S is fine for covering the outside walls.
Well done video. I have a fiber cement siding and I am curious if I can just throw this up or do I need a mesh? The underneath of the siding is not even sheathed to my knowledge but it has water resistant wrap.
Can you put lime plaster over a stucco house? Can it be put on wood eaves in fire prone areas? When you put over your earthplaster house, dont need prep except water wall? Do you make your lime putty as seemed expensive (thought ~$11/50lb bag Hyd. lime). Very fun, like your helpers also ! How often will it need a recoat?
I might have missed it, but, few questions: 1. The white lime puty you used in the beginning, it is already "ready". Did you create it yourself, or bought something ready? and if so, how is the ready mix called?. 2. Can you take that white puty as it is and put it on the wall?, or you must mix it with sand and water as you did?, and what happens if you do put only the lime puty alone?. Thank you.
@@kookia213 the lime putty is created by mixing powdered type S lime putty and water. You have to mix lime putty with sand to give it strength and prevent it from shrinking and cracking.
Hi, your video is amazing thank you! Would this technique work on an earthbag dome exterior and interior? Meaning a structure that doesn’t has a roof and with the roundness? Thank you again!!
@@HeirloomBuilders Thanks for the response! I was not sure if standard US market "Type S Lime" powder is suitable for this type of lime putty. Good info for others who may want to experiment with this technique.
Great work, I'm also plastering my strawbale house right now. What mix did you use in the other coats? What was the ratio of the materials. Thank you and keep up with this cool videos. Greeting from Portugal
I use the same ratio of 1 part lime putty to 3 parts sand for every coat. I make the first coat more wet than the final coats so that it doesn’t dry out before it has time to cure.
I'm building in six months and always wanted a lime plastered exterior. Can I lime plaster straight onto bricks? Thinking of using the usual cheaper brick commons used in similar rendering situations. Let me know if I'm over thinking it and I should just go with the brick (its easily available, lots of brickies about to lay them), trust the DIY lime plastering process with good prep, safety and good tools and it will work out fine. Thanks.
@@HeirloomBuilders oh and on cost, was that per coat? I saw you had your scratch coat on, so can I assume x 2? (regardless of AUD prices, seems way cheaper than paying renderer for modern day rendering job. And let's face it, it suits the house so much better and is healthier, nice energy gains etc. I'm building a mod barn style with 3 pavilions. A lime plastering finish will look divine - AND - not be like every other ' the norm' look modern render along the road!!!
Hey Logan! Love the channel and building philosophies. I’m building a red oak timber frame tree house, so I essentially have to do a 2x6 wall system (climate: northern Ontario, limited by sill plate size) otherwise I would do hempcrete or straw bale without a doubt. Do you have any experience applying lime plaster to rough cut wood or osb sheathing? Or any other option ideas for both my exterior and interior applications?
Hey Matthew! If I were building in Ontario, I would build a 2x6 wall with 2-4” of exterior rock wool insulation, with a rain screen mesh on top and fiberglass lath on top of that to hold the lime plaster. If you use 4” of exterior insulation, you should look into z girts to attach the lath. Don’t apply lime plaster directly to rough cut wood or osb, unless that’s going to be on the interior, like old school wood lath and plaster interior wall finishes.
@@GIBKEL this substrate was a straw bale wall- we plaster directly on to the bales. Otherwise a stud frame home would have plywood sheathing with two vapor barriers, a rain screen layer, lath and then plaster
@@HeirloomBuilders -thanks. Watch out on the straw as my fire fighter friend saw some rough fires. I don’t say that to be alarmist-I built a sauna here in Mt. knowing every sauna story I heard growing up ended in 💨. When I started building it 20 years ago, there were few books on it. All this lost, rare knowledge. Loved the video. Looks like a great house and much appreciated for video. Much love and respect!
Yes, you can see the 1/4” hardware cloth mounted on a wood frame we use to screen this sand for the exterior render. Interior plaster may need a finer 1/8” screen to get a smoother finish.
I want to construct my home this year. I live in Mexicali. B.C. México. It's one of the most hottest cities in the world. But we have higher dosis of chloride in our water..I listen that lime works better if you use sea water, would you recommend it?
Contact stucco companies for collor packs for cement based concrete. Buddy Rhodes concrete countertop is what I. Using on a plaster job right now. I'm using just over 2g per pound in my mix in a job today.
Would steel framing work or is wood better for straw bail? Edit: did some research, it's condensation, so you can if you cover them in wood. But how much support do the walls themselves need if the roof is fully supported by steel framing? Like if you leave the beams outside the walls, kinda like porch roof supports and then have the walls farther in with the wood to raise it off the concrete, wood at the top where it meats the roof, and wherever there are windows and doors. How much wooden support would the walls need? Also, can you make rounded walls?
Don't put lime directly onto steel though. It eats into it! You need to use stainless steel or plastic fixings. So if you have a steel frame, have something between that and the lime.
Could I do this on a square log dovetail cabin ? The logs are about 6 inches thick, how would I apply this lime plaster onto the logs? There is cedar siding on it now
If the cedar is still good, keep it the way it is. Otherwise, you’ll need to add a vapor barrier like tyvek or tar paper, Rainscreen mesh or wood strips, lath and then plaster. Cedar siding is pretty great too.
So after the third coat, how much was your average heating and cooling? I know it might be hard to figure if you are using solar, so you could do it in kwh per day. But how exactly are you heating and cooling would be useful information.
We heat with wood and can leave for a couple days when it’s below freezing and come back to a house that is still 60 deg F. The thermal mass really holds the temps. Same in the summer. All the thermal mass of the plaster holds the average temp while the hot summer sun is baking near 100 Deg F outside and the house only hits the low 80’s for about an hour in the early evening before the sun goes down and the cooling starts happening again.
I’ve never tried to spray lime plaster, but I love the idea of being able to save time and likely getting a really strong bond. The limitations seem to be having the proper equipment and skilled troweling labor. Spraying would go so fast that you would need someone constantly mixing batches of lime so that you don’t get cold joints having to stop and mix more plaster ever tile you run out. Mixing with a professional mortar mixer would be essential.
You can also make your own lime putty by mix NHL lime powder into a paste and let it sit wet in a barrel for a few weeks (the longer the better), THEN using the 1/3 recipe used here ! Search making lime putty !
I was watching and I thought about sharing something I know darn, I don't post....... anyway, adding ammonia will give you control for doing texture you can make texture with the trowel and then wait 20 min then shave it with the edge of the trowel. having bleached white sand will make you able to color it with special powder dye/pigment that is only for cement. can you imagen a kinda dark blue rather than taupe beige color, or iron oxide on some areas one more thing, about the grade of the sand, is it 0 or 1 that you are using ??? when I use to do my own mix 😉 30 years ago, I used 0 white bleached.
Those are good tips! Thanks for sharing. I don’t know what grade of sand, it’s fairly coarse mortar sand. I really do like the idea of adding some color, maybe even dark blue.
Thanks for replying so quickly .your videos and information great. Its not even save money and time also best siding we can have.trim and latch mean means? Are you referring for doors and windows.@HeirloomBuilders
@@andrewsackville-west1609Andrew couldn't you mix pigment to desired color into the lime putty when mixing with sand almost like using cement pigments ?
Paul clay doesn't have to granular texture that the sharp edges of masonry sand has and locking into each other and clay would definitely dry hard but be a soft easy break & flake out. Rough edge sand is the way to go !
@@HeirloomBuilders Aww I get it now for some reason I thought air is both cases. Although I didn't know there was materials that would let water through but not air I thought you need some kind of valve or something. Thank you for responding and have a wonderful day.
@@HeirloomBuilders Is there any videos of yours that you would recommend for building a homestead in Alaska? I'm looking to have greenhouses and raised chickens so I can be self-sufficient and off-grid but I'm just getting into this and would love some guidance.
Jake I've seen NHL powdered lime bags at my local HD here in CO. Now I'm not sure if it was extra leftovers from a special order but maybe hit up the contractors desk and see if they order it up for you ! Now that would consist of you having to whip up your own lime putty, plenty of tutorials for making lime putty, THEN mixing your own putty into a plaster with sand !
Another benefit is color. If you pour pigment onto the plaster mix you don’t have painting to worry about. Imagine a paint job every 6-10 years at thousands per job…
Bravo, I am a huge fan of lime plaster, maybe because i am from Italy ( Rome) . Cocciopesto and pozzolana were even common in roman time.

Do you do workshops? Would you ever do one in central Arkansas? (Asking for my future self, lol)
And what paint is ok to put over that? Thank You 🎉
Thanks for the video, you did a great job. Can it be applied over painted walls? Cheers from Mexico
Probably not a good idea over paint without some kind of lime binder or heavy scratching of the painted surface to help it key in.
@@HeirloomBuilders thanks for replying! Have a great weekend

@@HeirloomBuilders wow!!! Gracias! Que gusto leerle en español
Can you put lime plaster over fiber cement board?
Thank u for really a helpful informa..
Thanks for the video! Where do you obtain the Lime Putty in the US?
@@rayheilman9707 we get ours from Adam’s Products (a Newcastle company). Most masonry suppliers will be able to get Type S lime.
@@HeirloomBuilders Thanks for the response! I was not sure if standard US market "Type S Lime" powder is suitable for this type of lime putty. Good info for others who may want to experiment with this technique.
The foot coming out of the pet door at the end... LOL
Great work, I'm also plastering my strawbale house right now. What mix did you use in the other coats? What was the ratio of the materials. Thank you and keep up with this cool videos. Greeting from Portugal
I use the same ratio of 1 part lime putty to 3 parts sand for every coat. I make the first coat more wet than the final coats so that it doesn’t dry out before it has time to cure.
I'm building in six months and always wanted a lime plastered exterior. Can I lime plaster straight onto bricks? Thinking of using the usual cheaper brick commons used in similar rendering situations. Let me know if I'm over thinking it and I should just go with the brick (its easily available, lots of brickies about to lay them), trust the DIY lime plastering process with good prep, safety and good tools and it will work out fine. Thanks.
Seems fine to me, I would use commons of a textured brick if you can find them for better adhesion.
@@HeirloomBuilders yeah, we have 'scratched' commons too.
@@HeirloomBuilders oh and on cost, was that per coat? I saw you had your scratch coat on, so can I assume x 2? (regardless of AUD prices, seems way cheaper than paying renderer for modern day rendering job. And let's face it, it suits the house so much better and is healthier, nice energy gains etc. I'm building a mod barn style with 3 pavilions. A lime plastering finish will look divine - AND - not be like every other ' the norm' look modern render along the road!!!
@@MM-li8nk that cost is for three coats
@@HeirloomBuilders even better!
Hey Logan!
Love the channel and building philosophies. I’m building a red oak timber frame tree house, so I essentially have to do a 2x6 wall system (climate: northern Ontario, limited by sill plate size) otherwise I would do hempcrete or straw bale without a doubt.
Do you have any experience applying lime plaster to rough cut wood or osb sheathing? Or any other option ideas for both my exterior and interior applications?
Hey Matthew! If I were building in Ontario, I would build a 2x6 wall with 2-4” of exterior rock wool insulation, with a rain screen mesh on top and fiberglass lath on top of that to hold the lime plaster. If you use 4” of exterior insulation, you should look into z girts to attach the lath. Don’t apply lime plaster directly to rough cut wood or osb, unless that’s going to be on the interior, like old school wood lath and plaster interior wall finishes.
I would look into straw-clay system.
Where do you get that cool colored sand. Mortar sand in my area is nothing like that.
@@weshunter1540 our local mortar sand has a lot of clay in it. You could add clay or bagged color if you want a different color
Grate video, where do you get the lime putty?
We got our lime putty from Adam’s products an old castle company. Any masonry supply store should be able to get it.
Subscribed! Can I use lime plaster instead of concrete for an underground dome home?
I’d have to see the design and circumstances, but probably not.
Didn’t catch what the substrate should be? Lathe and plaster is my only experience here in MT.
@@GIBKEL this substrate was a straw bale wall- we plaster directly on to the bales. Otherwise a stud frame home would have plywood sheathing with two vapor barriers, a rain screen layer, lath and then plaster
@@HeirloomBuilders -thanks. Watch out on the straw as my fire fighter friend saw some rough fires. I don’t say that to be alarmist-I built a sauna here in Mt. knowing every sauna story I heard growing up ended in 💨. When I started building it 20 years ago, there were few books on it. All this lost, rare knowledge. Loved the video. Looks like a great house and much appreciated for video. Much love and respect!
Do you screen the sand for the any of the coats? I've seen some people use a window screen or 1/4" hardware cloth.
Yes, you can see the 1/4” hardware cloth mounted on a wood frame we use to screen this sand for the exterior render. Interior plaster may need a finer 1/8” screen to get a smoother finish.
I want to construct my home this year. I live in Mexicali. B.C. México. It's one of the most hottest cities in the world. But we have higher dosis of chloride in our water..I listen that lime works better if you use sea water, would you recommend it?
Hahaha. NEVER use sea water.
Great video! Thank you!
Thanks for the info. Looks great.
How thick is the plaster on the exterior?
1” thick on the outside. Thicker in some spots that needed fill.
can you use this on green sip system OSB?
You would have to do a stucco finish on zip. It's what is always done. There are lime plasters available.
Heirloom what your take on coloring wall, add pigments to the lime putty OR pigment in a watery slip and brush it on ?
I wish I had an opinion on this, but I don’t have enough experience with colors to help. I usually keep it natural.
@@HeirloomBuildersI guess it's going to have to be a live & learn test trial experiment thing, thanks anyway !
Contact stucco companies for collor packs for cement based concrete.
Buddy Rhodes concrete countertop is what I. Using on a plaster job right now.
I'm using just over 2g per pound in my mix in a job today.
Would steel framing work or is wood better for straw bail?
Edit: did some research, it's condensation, so you can if you cover them in wood. But how much support do the walls themselves need if the roof is fully supported by steel framing? Like if you leave the beams outside the walls, kinda like porch roof supports and then have the walls farther in with the wood to raise it off the concrete, wood at the top where it meats the roof, and wherever there are windows and doors. How much wooden support would the walls need? Also, can you make rounded walls?
Don't put lime directly onto steel though. It eats into it!
You need to use stainless steel or plastic fixings. So if you have a steel frame, have something between that and the lime.
How will that work in cold climates such as Michigan that are high humidity and freeze and thaw?
@@chubbaalf44 I don’t know for sure, but I would think it would be okay. Lots of buildings like this in Chicago
Could I do this on a square log dovetail cabin ? The logs are about 6 inches thick, how would I apply this lime plaster onto the logs? There is cedar siding on it now
If the cedar is still good, keep it the way it is. Otherwise, you’ll need to add a vapor barrier like tyvek or tar paper, Rainscreen mesh or wood strips, lath and then plaster. Cedar siding is pretty great too.
Wait,you say i make it at home?how to make marmorino for floor,or somethig similar?Thanx
Well done and helpful
Can lime plaster be used to parge a cement block wall?
I think so, but I would add some cement in there to help it bind to the concrete block wall or add a bonding agent to make sure
Very good! Subscribed!
Can you use this on a peir home in louisiana?
Will this withstand hairline cracks when a nail is hammered into that wall?
It’s best to pre drill a pilot hole to prevent cracking
So after the third coat, how much was your average heating and cooling? I know it might be hard to figure if you are using solar, so you could do it in kwh per day.
But how exactly are you heating and cooling would be useful information.
We heat with wood and can leave for a couple days when it’s below freezing and come back to a house that is still 60 deg F. The thermal mass really holds the temps. Same in the summer. All the thermal mass of the plaster holds the average temp while the hot summer sun is baking near 100
Deg F outside and the house only hits the low 80’s for about an hour in the early evening before the sun goes down and the cooling starts happening again.
@@HeirloomBuilders OK thanks for your reply. How many cords of wood do you use in the winter?
@@jasonbourne1596 we use 1.5-2 cords of wood per year
@@HeirloomBuilders Thanks
Could you explain spraying lime plaster compared to troweling on lime plaster? Thanks.
I’ve never tried to spray lime plaster, but I love the idea of being able to save time and likely getting a really strong bond. The limitations seem to be having the proper equipment and skilled troweling labor. Spraying would go so fast that you would need someone constantly mixing batches of lime so that you don’t get cold joints having to stop and mix more plaster ever tile you run out. Mixing with a professional mortar mixer would be essential.
Where do I get the material from ?
Can I put it directly on wood siding, instead of vinyl siding?
Yes, with tar paper, a Rainscreen mesh and fiberglass/metal lath as your prep layers.
Where do you buy the lime putty from? I can't find it anywhere but online and shipping is expensive.
Adam’s products stocks hydrated lime. The are an old castle company that deals in concrete block and masonry products
You can also make your own lime putty by mix NHL lime powder into a paste and let it sit wet in a barrel for a few weeks (the longer the better), THEN using the 1/3 recipe used here ! Search making lime putty !
Yeah NHL plaster is the true lime putty plaster.
Yes it's pricey in the US. There's only one plant that makes it in Canada.
I'm building a Tiny Home, for long term parking not for travel. I wanted a stucco look but stucco is so heavy, will this have a simular weight?
Yes it will be just as heavy
@@HeirloomBuilders Thank you!!
Put acrylic stucco on it. There are thin option.
I was watching and I thought about sharing something I know
darn, I don't post.......
anyway, adding ammonia will give you control for doing texture
you can make texture with the trowel and then wait 20 min then shave it with the edge of the trowel.
having bleached white sand will make you able to color it with special powder dye/pigment that is only for cement.
can you imagen a kinda dark blue rather than taupe beige color, or iron oxide on some areas
one more thing, about the grade of the sand, is it 0 or 1 that you are using ???
when I use to do my own mix 😉 30 years ago, I used 0 white bleached.
Those are good tips! Thanks for sharing. I don’t know what grade of sand, it’s fairly coarse mortar sand. I really do like the idea of adding some color, maybe even dark blue.
How plaster over osb or plywood sheathing?
@@AmrikSingh-rw6ew 2 vapor barriers like tar paper and then a rain screen mesh, then lath and trim and finally plaster
Thanks for replying so quickly .your videos and information great. Its not even save money and time also best siding we can have.trim and latch mean means? Are you referring for doors and windows.@HeirloomBuilders
How about using Diathonite plaster
Wyndmoor PA USA
Thanks alot amazing video
Question. Do you apply exterior paint on top of the lime plaster? is it ok ?
I would not apply paint to the exterior. It is very weather resistant all by itself
You could limewash it, if you want a color change or a different finish.
@@andrewsackville-west1609Andrew couldn't you mix pigment to desired color into the lime putty when mixing with sand almost like using cement pigments ?
The fires in the kiln are not carbon neutral. Curing lime does absorb CO2, but not enough to offset the energy needed to drive off the CO2.
Can you lime plaster over stucco ?
What about using clay instead of sand.
Wyndmoor PA
Paul clay doesn't have to granular texture that the sharp edges of masonry sand has and locking into each other and clay would definitely dry hard but be a soft easy break & flake out. Rough edge sand is the way to go !
How is it both breathable and air stopping? I thought those two things were mutually exclusive
Think air tight, but vapor permeable. Moisture can migrate through materials that air cannot.
@@HeirloomBuilders
Aww I get it now for some reason I thought air is both cases. Although I didn't know there was materials that would let water through but not air I thought you need some kind of valve or something. Thank you for responding and have a wonderful day.
@@HeirloomBuilders
Is there any videos of yours that you would recommend for building a homestead in Alaska? I'm looking to have greenhouses and raised chickens so I can be self-sufficient and off-grid but I'm just getting into this and would love some guidance.
@@zeroexea ua-cam.com/video/s5muR_bJRg8/v-deo.html
I am building a tiny house
Can i put this on wood?
Yes, but you’ll need 2 weather resistive membranes and a rain screen and lath under the plaster
Thank you
Does this stick to raw adobe walls?
Why is there that wavy line closer to the top that looks like a big crack or change in material?
It’s the original lime plaster with clay render beneath that was still strong and was not removed during the repair process
I have a moble how can I save it the exterior walls are shot
Can it be tinted or painted?
@@CynthiaWithLove for sure. Tinting is better for breath ability
Thank you@@HeirloomBuilders
Hey Logan any updates?
Happy to find your channel through homesteady
new sub
Welcome aboard!
Do you need line putty or can you also use clay?
You can use clay, but it won’t hold up to rain very well
@@HeirloomBuilders clay is water soluble, lime after it has been hardened by exposure to CO2 becomes more like stone.
Thanks!
Thank you! Much appreciated.
can you get this type of lime at lowes or HD?
Not in my area. We have to go to a masonry supply store.
@@HeirloomBuilders thanks! i'm in Hickory and i can't seem to find any, suggestions for supply stores?
Jake I've seen NHL powdered lime bags at my local HD here in CO. Now I'm not sure if it was extra leftovers from a special order but maybe hit up the contractors desk and see if they order it up for you ! Now that would consist of you having to whip up your own lime putty, plenty of tutorials for making lime putty, THEN mixing your own putty into a plaster with sand !
@eugeniotapia6765 Yeah that's not an HD product. NHL doesn't even come up on their site. Had to be a special order.
Another benefit is color. If you pour pigment onto the plaster mix you don’t have painting to worry about. Imagine a paint job every 6-10 years at thousands per job…
Can I put this over and old retaining wall that has concrete mortar?
Probably so. I would recommend a mix of lime with some Portland cement or a binding agent to help the binding to existing mortar
