Steel fixings in contact with hempcrete should be painted
with a protective coating.
Any metal fixings within a hempcrete wall that are exposed to the cast material - however
minimally - such as screws, joist hangers or straps, should be of stainless steel. If the par-
ticular fixing required is not available in stainless steel, then steel, or galvanized steel, can
be pre-painted with an anti-corrosion coating and painted again once installed (in case the
process of fixing has removed some paint) to protect it from corrosion; however, this solu-
tion should only be used as a last resort.
