Hemp-lime-plaster are very similar to clay-plaster, but are much easier to process with a normal plastering machine, also available in the silo and are about twice as hard as clay-plaster which minimizes crack formation. Additionally, hemp-lime-plaster is cheaper than clay-plaster. 

Every construction site is different, and so are the principals. Thus, hemp-plaster can also be individualized.

A standard amount of hemp is added to the packaged sacks. Simply add water and the plaster can be processed.
If you want a coarser structure or a more rustic one, you can add different types of hemp hurds to the fine-plaster, even with different colour pigments.
