Have you experimented with spraying hempcrete onto a regular stucco home to protect from fire and EMFs? I would imagine that it would stick just like it does to pre-existing hemp walls.
I would love to build with hemp!
They may be legalizing in New Mexico soon!
This mix will stick to anything if done properly. Good Luck in NM
What is the formula that you are using to blow it in?...i have been working on a similar small scale hopper..also where is the best recourse for the hemp husk?
@@gilbertolais2180 The binder is created by Ereasy in France and contains natural cement from Grenoble and Methylcellulose it is the least bider added to any solid Hempcrete material. Where do youlive to help with your hemp supply and the machine works by sucking not blowing the material.
@@Hempbuildingbook sorry I'm just getting back to you... first of all... My humble gratitude for you getting back together responding with completely open source and with the bigger picture in mind it feels like these days people are competing and they don't even know why I plan on sharing all my information as well completely for your charge to anybody who wants to know so you guys are awesome... But to answer your question I'm in San Diego and I can see what you mean about sucking the hemp Crete instead of blowing.... So in other words it's more like a vacuum then a paint pot as far as the material from the hopper gets sitting into some kind of interior where the vacuum is pulling it through? I would use any of the help but you guys are willing to give me very much appreciate it I am a precision metal fabricator and machinist so I'm coming at this from a pretty solid construction background and fabrication... But I'm just trying to save time by not having to r&d all the same mistakes that obviously you guys have already gone through so I appreciate that and all hardly understand the paint stinking price that was paid for this knowledge! I have an idea of utilizing aluminum extrusion in a frame of something like two feet by four feet or five feet by three feet and different dimensions to make panels of hemp creet that are framed in by these extrusions deck him easily interlock to give you a water airtight seal I need maybe one or two pins to hold the whole thing together... Because the texture is pretty rough in fibers ..I like what you guys do with the drywall mud I was thinking could there be a full hemp substitute and installation would be something like venusian plaster but I would imagine that the fibrous husk would have to be ground up really fine in order to get a more mortar or stucco like texture or even plaster... Like I said I'm very grateful for you sharing the knowledge much appreciated thank you
how does it compare in terms of acoustic insulation relative to acoustic plasterboards or infill rockwool, etc? Any good?
As with all hempcrete it works accoustically very well
mmm that outer wall looked nasty. Just the way I like it.
So it's just insulation not even close to concrete
Not just insulation but thermal mass and a vapour porous envelope nothing like concrete.
What if you fed the hemp to some ungulates...the digestive process would render the hemp fibres softer and more malleable. And as we all know, nothing sticks like sh:t.
Pax:)
The reason to feed Hemp fibre to cattle is to slow the digestion and help prevent mastitis. No need to improve Hempcrete however shit might help adhesion.
@@Hempbuildingbook i can confirm that shit adheres well to the side of my house
Is there much lime in that mix?
The ratio of Hemp to binder with the Ereasy system is 15 kgs of binder to 20 kgs of Hemp so about half the normal amount.
Does hempcrete degrade from rain and humidity? Or will it still need waterproofing and vapor barrier?
it will require a lime render or timber or slate cladding which would need an airgap to allow wall to breathe
Interesting, but how do you finish it? Can you trowel it? Use wall sheathing? Lath & Plaster? I saw a Build Show video where they were using plywood forms and filling them with Hempcrete like rammed earth filling wall cavities for an external, non-structural infill wall. The product seems to have some remarkable properties.
I've seen with this method they blow it through a steel mesh, that helps you know the depth and also they go over it to smooth out, The finish to get the best qualities from the Wall would be Natural lime plaster I believe.
A coat of Lime and sand render works fine. two coats is sufficient except in high rain regions in which case a good scud coat and then 3 coats.
@@EastyUK The steel mesh provides a guide for the surface level.
Is that a pure natural mix? or is it with Portland cement?
No Portland cement only the Ereasy binder which contains Natural cement from Grenoble.
@@Hempbuildingbook So is it just the hemp alone or is it mixed with anything? If so whats the binder?
@@sKeM2k9 Almost all hempcrete uses lime.
Wow.fireproof
The thatched roof on the rest of the house sort of makes that irrelevant
Not at all as the Thatch has a layer of hempcrete beneath it and so is also protected.
Leave it to hippies to figure this out . But you may be on to something good !!
The Romans used hemp cement. They figured it out, not hippies. It's been tested and tried and true for thousands of years already. ;)
Nothing wrong with Hippies or their ideas.
