Breathable Plasters

Clay/hemp Plaster

Fibrous clay plaster is the ideal finish for your hempcrete walls. It is the most vapour permeable plaster allowing your hempcrete greater access to the moisture vapour in the air making best use of hempcrete’s humidity buffering capabilities.


Instead of sand our clay plaster uses fine hemp shiv as aggregate, this increases its breathability by creating tiny pathways for moisture, increases its flexibility and also locks up more carbon in your home.


Our clay plaster is 100% natural and white in colour.
