STEP 1: Get Your Hemp Hurds

(Hemp hurds are also known as 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.
