Getting the basics right - The Hempcrete Topic: Designing and Building with Hemp-lime - page 101

cast-in-situ hempcrete is either completely encased within the hempcrete or at least hidden
from view in the finished wall, so it is not necessary for this to be a beautiful feature with a
high standard of joinery. As described earlier, the process of mixing and casting the hemp-
crete itself, while not exactly complex, requires a certain level of knowledge and skill to
ensure mistakes are not made. However, it is also at this stage that best use can be made of
inexperienced volunteer labour (see opposite).
When it comes to applying finishes, the skills needed will depend on the type of finish
chosen. Finishes range from lime plasters and lime renders to cladding in a variety of ma-
terials, for example timber, brickwork or stonework. The application of lime plasters and
renders is a distinct skill, different from working with gypsum plasters and cement render,
and it should not be assumed that just because someone is skilled at the one, they will be
able to do the other. That said, although lime plastering is a specialist trade, depending on
the level of finish desired, many self-builders may also be tempted to have a go at doing
this part of the work themselves. For more on this, see Chapter 18 .
In developing the skills of the team, training courses may be a first practical step. Courses
in building with hempcrete are available (see Resources ), though still few in number.
Courses in lime plastering are now readily available all around the UK, and attending one
is recommended for those with no experience who intend to do their own plastering.
