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.

Lime Render

Lime render is the simplest external finish for hempcrete, it is durable, beautiful and breathable.

 

Our lime render can be trowel or spray applied and can be left natural or painted a breathable external paint or lime wash.

Hemp Block Mortar

Standard hemp block mortar – When using hemp blocks in conjunction with sprayed hempcrete or other insulation and cold bridging is not an issue.

 

Insulating hemp block mortar – When using hempcrete blocks through the entire thickness of the wall, our insulating hemp block mortar eliminates cold bridging through the mortar.
