We are Jim and Jessica, a husband and wife team who made the leap from city life to an off-grid homestead in Southern Arizona. We've started this lifestyle equipped only with two Permaculture Design Certificates and a whole lot of determination.
We’d like to share our journey of starting a sustainable homestead from scratch with all its ups, downs, and lessons learned. Watch us take on the challenge of modern homesteading, off-grid life, and turning this barren piece of land into a desert oasis.

We live in a similar climate. Most of the old buildings in our area(100 years plus old) are built with clay. They get painted with a lime, linseed, salt and water mix. We get very wet winters, and these buildings have survived for hundreds of years.
Where is that kb

I remember seeing the adobe houses and buildings painted in a limewash mixture that will help the homes and buildings cooler during the hot summers and protected from insects boring into the adobe. This limewash can be applied easily with a 4 inch brush and reapplied over the years as needed. The linseed oil will work as a water repellant.
This modified lime plaster seems like the nicest of what you've shown, both to work with, least amount of work with just one coat, and the whitest for sun reflection. I don't know how much eggshell and fur you have to work with, but if you covered al least above the gutters it would keep the house cooler. Below you could probably do fine with the manure plaster, since it has the least material cost. You could probably apply lime plaster over it if you didn't like it.
...anyway. for the algorithm!
I'm in agreement here.
I probably would go with a line plaster for good solid coverage and then a linseed lime wash for waterproofing. That's just my idea.
I have learned so much just watching your videos. Thanks for letting us see this process. None of us know how much we may need in the future. 👍👍❤️
That sounds good for longevity.
Just a gentle reminder of the volatility of linseed oil. Rags/paper towels with linseed oil drying on them can spontaneously combust. It’s a great protective oil, but take the necessary precautions.
Plaster with the wash on top. You can reapply the wash every few years as needed to maintain a water repellant surface. Oh, and could you use the cobb sprayer for the plaster to cover areas quickly, then trowel over it to get the desired finish?
Nice to see Crew is still contributing to the project! 😁😁😁👍👍🎉🎉🎉🎉🎉🤘🏻🤘🏻
Definitely lime plaster. It also has the benefit of being antifungal and antibacterial. So, it's excellent for inside walls, too
Lime plaster, I think would be more weather resistant and faster in the long run ❤️🇬🇧
I sit here and watch you two, and you seem to grow closer each day. And I can't wait to head up north and start my adventure, to experience all the wonder that off grid life will hand me. I pray for you daily, for safety and good health 🙏🇺🇲🙏😎🙏
Jen's boots are the coolest custom design I ever seen. They should go into the " Homsteader hall of fame" they look so comfortable. Maybe she can do a closeup video explaining how she revamped them to look so neat so we city folks can look like genuine homesteaders too.
I think the Lime wash would be the best as it would water proof the cob as well as reflect some of the heat. It would have the added benefit of being easy to apply. I think with a wooly roller the lime could be applied to a larger area quickly. Roller scan have long handles added to them to make it even easier and faster too. Just like painting.
a brush is best ( a boars hair to be exact fake bristled brushes do not do well ) it isnt paint it does not act , it is not fluid or silky like paint , my husband even tried running it through a dry wall texture gun it worked to some degree but did clog the spray tip took for ever to unclog it was not worth the hassle
i would go with the lime plaster, myself, i lived in phoenix for 10 years and that's the best i've seen for protecting cob.
02:34 That was the microsecond when the oil became cold again 😂
for a sparkly look you might add mica powder to the lime.
Good afternoon, Green team, I think the lime plaster with egg shells and hair did a great job, just my opinion, but you know what you like best, be safe and God bless..
I like it , wear a mask when mixing large batches , dont breath the lime dust , the white color will reflect the sun and keep things cooler , you go girl
I'd personally go with the Lime Plaster and animal hair combo (maybe see if a neighbor has alpacas, goats, or maybe even chickens to add to the fiber supply), then I'd use the lime/linseed wash over top of that as an ablative later than can wear away instead of the Plaster and cob layers.
I'd do this because I think the lime Plaster will last longer than the wash, but adding the wash is easier to do year after year, so in the end the added labor in the beginning means less labor in the future. Keep up the work it's looking fantastic! 👌
lime plaster works great for indoor use. adding the puppy fur is a good idea
I’d vote for the mix you used today. It looks much better than any previous mix.
Limewash for sure. Easy to apply and easy to reapply.
Lime plaster looks good. Maby use a hawk and trowl on large areas. Faster and puts more material on easier.
thanks for sharing your methods & ingredients for plaster, I smiled when you brought out the dog fur...
Nice work filming Jim, great product testing Jess
I was raised in the country . As a child neighbors helped out one another. Many times coming up I would delute paint with water so it went future. And white wash barns fences etc . So you are basically white washing the house. Your lime white wash will actually help keep out unwanted critters.
In your intro, Jim, you exclaimed "eeeyoy!" Sounded like Tellie Tubies!
Plaster looks great!!!
I am sure you folks will get this all figured out. Way to go guys. I am loving the rain here!
Thanks Don! The rain has been great
The lime wash repels water nicely and it looked thin enough to apply with a thick roller which would speed the process up.
If you use the one that was like frosting , when you do the dome you would be able to use a texture machine that is used to spray sheetrock with joint compound. I did it on a block wall house doing a couple of layers and it worked great. Maybe shoot the lime mixture on then use a garden sprayer with the Linseed oil to seal it. And as time passes you can add more oil as needed. A texture machine is 110 volt and rentable too.
I like the looks of the lime plaster and seems like it will be more efficient to apply needing only one coat. You might see if you can find some crushed or ground recycled glass to use as an aggregate instead of sand. The glass will not darken the plaster like the sand does and you might get some cool color effects from the glass. Also, linseed might not be good if you plan on collecting water off the structure.
It's a raw linseed oil, so it should be fine.
The stucco look of the lime plaster looks good! Could always use the lime wash over top in the future too.
Thanks for sharing 👍😀
Looking great guy's on the Plaster mixed.
I love you two! Such genuine down to earth HuMan Beings! It is so admirable, the way you are creating a home out of earth, in the desert! Pretty dang cool, hee hee! ♥️❤️👍🏼👍🏽🌹🙏
Lime plaster. Go for it!
i'd use the wash with oil and apply heavily with a power sprayer for 2 (or more?) coats. it would be faster, plus more thin layers should mean deeper penetration initially for better waterproofing and durability and easier on your bodies to apply.
like you said i like the way the plaster was applied better, Seem to me more sealant. That would be my choice
I do like the lime plaster, and it seems to go on well. Here's a crazy 🤪 think, if you colour tint each batch differently your house will match the shingles 👍
We may end up doing that.
When I. Whitewash my fences I use a fertilizer sprayer,the tip can be motefied to spray it thicker coats,it takes me about 1\2 a day to spray 1200 feet of my fences with 2 coats. Also look up what a hawk trowel is you might like it.
Lime plaster would be my choice.
Hi, if you want to take a look at Kris Harbour videos, he has a home made lime barrel and a mixer he made with 2 wheels in a tub affair, it's really clever. He covered his whole hobbit type house with lime plaster. It just might help u guys
I enjoy Kris's videos too.
Lime Plaster. Jim I wonder if the sprayer that you tried long ago with the mud/straw would apply that nicely.
You could also add a dye to the lime plaster to make the dome a light brown color.
The plaster consistency, looks much like drywall mud. Watch some videos on applying that, it may speed up applying it, it could go a lot quicker
You guys could use diatomaceous earth for the sand in your lime plaster. They sell it for pool filtering. It's not expensive and it's white like ground up egg shells. Silica sand.
Just don’t inhale the dust
It does keep the bugs away
I think the lime plaster was easier to mix up other than the dog hair. It seemed to apply much better and consistently and keep a whiter color which will be good in desert environment. It would be good to see how it holds up to the heat and rain. Good luck with this step. Great job with your trial runs and research👍😊
It looks great! I love the white. I plan to do something similar but with teal trim. ❤️🥰👌🏽
Lime plaster would be my choice. Good luck!!!!
Jessica that is pretty white on that different brat plaster using his pretty pretty nice white wash for the for that little place it look good on your house it would feel reflect the heat from your bags Hauser keep up the good work U2 U2 make a beautiful job together
We have been working with lime plaster for few years and use linseed oil to seal adobe walls. For a first coat of lime we use a slurry scrubbed in with a stiff brush. We keep all lime work out of the sun and use mist and cover for several days with damp burlap that doesn't touch the lime. Lime needs to cure slowly. Not that you keep it wet! Cured quickly it is fragile. Kept damp and it falls apart. We wash our sand because it is very dirty and for applying 1/2 inch we use one part lime to 3 parts sand and test it by forming a ball and dropping on the floor. If it splatts it's too wet. If it cracks it's too dry. aWe have found that using pressure to apply it makes a very hard plaster. we use a rectangular wood tool, like you have in metal. We have made a lot of mistakes and will continue to, but this is what we have learned so far. I am restoring an old. adobe house. I think how we decide to do work on mud walls depends on how often you are willing to repeat the work. Linseed oil thinned painted on adobe is every 3 years, lime/sand slurry about the same. Lime plaster lasts many years. My house is big, so I want to plaster as much as possible, but 3/4 inch of plaster is a lot of work for large exterior walls. We're working on the moldings now, a year later sealing,
In the back of my mind is something from 50+ years ago where ground up egg shell was added to a mix and it helped with the water repellency. You could grind egg shells in your mixer by adding some small rocks in with the shells and letting it run. Pour that over a screen and the good stuff will fall through. Light colors reflect light and heat better than darker colors. Painting the dome with white stucco will make it much cooler in hot weather. A buried(at least 36" down) fresh air inlet pipe will bring in cool air during the day if you have a hot air outlet vent near the top of the dome. Good Luck, Rick
I was thinking, how do I search their videos for the one that has Jen fixing her boots up, which video was that? Agreed!
@@naomimcculloch Sorry, I don't know. Good Luck, Rick
do you guys ever look at the comment about what you are doing - well that lime mix is not much different than the stuff we use on ceilings in homes when we do popcorning you could get yourself a hopper put that stuff in it and spray it on and you could spray that whole building in an hour or so and get two or three coats in one day because it would dry better I know we have put a lot of the popcorn on over the years just trying to help god bless
great idea
The no fly zone was funny !
For me definitely.......
Lime Wash
If you could keep agitating the wash, ie. shaking, could you use hand held spray bottles to apply the Lime Wash coats?
The consistency, at least on TV, looks thin enough.
As always
Massive Respect from Aotearoa, New Zealand
😀👍💙💛
I a team Lime! for centuries it has protected European mud brick and stone structure from weather, insects, heat...some reapply every year to make sure there are no cracks and stuff....that was great work and application , you diva of architecture! love and blessings to all three! or should I say 4 no w that the house is built and its taking on a life of its ownnnnnnnnn
No to the horse stuff. Can't wait for the outside to get finished. one suggestion is to work top down from the roof so water will not accumulate behind the finish coat. You decide what is best but let us know.
Looks great!
The lime plaster with the linseed oil (combining the ideas) might be good end solution. Also the lime wash might be a good tool for an annual "top up" layer after the plaster has been applied to strengthen the plaster.
I definitely like the lime plaster more, but if the wash is a lot more economical, even with multiple applications, I know that's probably a factor. As long as it gives equal protection.
I liked this last one with the modified lime plaster.
I like the finish!
Wow lots of advice. Nice
Y'all got this, I m excited to see what y'all choose.
Declare a no fly zone, hahaha! Very clever! :-)
Where does one acquire 50lb sacks of powdered egg shells and bales of animal hair? You have a big dome. Coating inside and out will up to a lot of square feet. My vote goes for the simplest materials and fastest application technique. Get protected. You can experiment on subsequent coats after the monsoons.
I like the lime plaster.
A master piece
Very interesting & educational.
I think you might want to try a better brush for applying the lime wash. Those little brushes were too small, except for edging around the rocks. I saw someone put a lime wash in a barn, it was a big sloppier brush. Maybe watching a plasterer on YT could be helpful. Like applying the skim coats in house walls. Thanks for all your work to bring these videos to us! You two are amazing. :-)
Lime plaster!!! Then top coat with the wash. 🤞🏾
Hey whatever you see works best. Exciting to do the comparison. Best wishes!
Modified lime plaster!
Definitely the lime plaster.
Great video again guys!
Look forward to seeing what you end up going with.. this was commonly used in England for centuries there must be some historical UA-cam videos on this that mention the best/most durable type of lime plaster as we get severe weather in England loads of wind and rain! So it'd have to be pretty hardy! (Just an idea before you make a final decision!?) Might be some online documentation that gives the correct measurements for mixing it aswell perhaps as there are a lot of historic buildings still have that finish in England in the country and have to be renovated using the traditional methods they were built with so that's the only reason I mention it as it's still used today on some old building renovations..
Great job though look forward to the next one!
Cheers from London 👍😎🏴
I can't wait to see the doom in white colour
hmm choices lol . in a perfect world lime plaster would be the choice . i like the egg shells but lets be practical . the lime wash is going to be the easiest for the mass of the job at hand . and small scale egg shells are ok but for the mass of the dome thats alot of egg shells . im going to say lime wash is your best bet to finish it in a practical time . maybe a lime plaster with out egg shells but i think a wash would be your best bet .
testing and experimenting is great for those who are I terested in the building and best way to do this... but even for folks like me who are watching to live vicariously it's good.. because we want you to succeed in the whitewash covering if the house.
I think the dome will look really nice with the white lime wash/plaster. I couldn't tell you which was the better one to use, though.
I would recommend plaster on the roof and wash on the wall... perhapse in the future using roller to add extra wash...Awesome work Gratitude and Appreciation for sharing your creations 🙏🏻💚🤞🏻
I think the lime plaster is the way to go.
Lime plaster - tried and true
I'd go with the lime + linseed oil wash you did first today but use a paint sprayer and do a few coats. It will go real quick that way.
I’d do an undercoat of clay with less straw than your coat right now on the dome, thin layer really to sooth it out (important for water shed) and then spray paint or large brush lime wash it. No linseed oil. Lime wash again and again. Then linseed if really you feel you need it.
Or a lime plaster with white sand or eggshells or oister shell, whatever fine agregate. Could even be perlite or cork dust for insulative properties.
I like the addition of the linseed oil. I think you should add it to whatever you guys choose to use.
Please read some of the comments where they're suggesting what you can use to make the application go faster, lots of great suggestion of equipment that's available and not very costly.
With the intense heat of the sun, you don't want to be out there for hours and you don't want this process to take weeks and weeks, especially since it's monsoon season shortly.
I used lime plaster (aka: NHL) and am confident in its ability to protect the underlying materials. Depending on its thickness lime plaster needs to be kept moist for a number of days for the enzymes to bind together. Best of luck with whatever you do.
You will probably do the lime plaster. Personally I'd do the lime wash for its speed. Although I dont know how well itll protect the dome. Cant wait to see what you all do.
lime plaster was really good. your limewash was very weak but dried well & i dont think there wouldve been enough oil in the mix
Lime plaster ❤
Fun to watch. interesting idea's. I have a ranch west of Phoenix. trying to figure out how to do a rammed earth perimeter wall with natural ingredients. maybe cob would be good with a plaster mix.
I think you'll get a good look at which one last over time. By the time the second done is complete you'll be seeing how each type of plaster performed.
Lime plaster seemed to be the best. Hope those were not the biting flies. Stay safe!
Thanks CB! We usually don't get too many biting flies, but on rare occasions maybe a few.
The Chinese used glutonous rice flour on the great wall which made a very strong mortar.
I think the modified plaster and if you’re talk about doing it in the house then you could use a drywall hopper and shoot it or that one hopper thing you got and just shoot it on the wall and then she come behind it and smooth it out and make it really nice
My Guess is it has to do with the color, a light color will reflect light and heat more than a darker color.
You can do another test
Put a white painted and a black painted item in the sun and then test it in the shade.
You will find the white will always be lower temperature.
But you can do the test and see if you agree with me.
Looking very nice
I just love what your doing.
Maybe look into stucco recipes. I used a ceiling spray once on a wall it worked well.
Impressive :)
I've no input, just waiting to see what you choose and if you fully considered the monsoon conditions when you do! Can't wait
My guess is: Lime plaster on done and in the eave (since it seems to repel water more) Then Lime Wash on the walls.
I like the idea of egg shells with the hair. To reuse and get what you need by using free products, which you can save for. Hope you don't have to do this yearly...but checking to make sure all is well by yearly maintenance or seasonal maintenance is good. I wonder if birds might try to get the hair when dried? Hope there is a smell so they don't want to get the idea. Would linseed oil or the smell be noticed inside?
