In this post, you’re going to get a step by step visual guide on how to mix and work with HempCrete for your next building project or art piece!
There are so many things that you can do with hempcrete, but understanding how to mix the 3 simple ingredients is key.
Just with any recipe, once you get the hang of it, you won’t even need to follow a recipe, you will just be able to see the fluffiness of the materials or how wet it is and you will know what it needs.
To make it easier to understand we’ve designed this infographic for you.
So take your time understanding this, and if you have questions feel free to leave them below and we will be happy to be of service.
STEP 1: Get Your Hemp Hurds
- Get wood chip sized pieces .5 in – 1.75 in
- Ratio of Hurds: 6.2 – 6.8lb/ft3
- It’s the core fiber of the hemp stalks
- Ideally free of dust
- Minimal amounts of long bast-fiber present in the hurd.
STEP 2: Get Your Binder
- Powdered form of Binder
- Comes in 50lb bags
- 10lbs/ft3 is required
STEP 3: Making the HempCrete
- Start your mixer
- Add hemp
- Then add the water
- Make sure the hemp gets wet
- Add the binder
- For best results apply within
- 20 – 30 min after mixing
STEP 4: Preparation & Framework
- Use 16”-24″ plywood or OSB for formwork
- Attach the formwork directly to the studs using screws
- Make sure the formwork is level and vertical
- Check the distance from your formwork to the stud, that will direct the thickness of hempcrete.
- Use spacers for fast installation.
- No need to treat timber or framework with oil or lime wash.
- You can remove the formwork instantly after you reach the top of it with hempcrete
- Shift your formwork upward half way to the hempcrete mix and
- Repeat all the steps again.
