Mesh sunk into basecoat plaster.
To apply the reinforcing mesh:
Cut pieces of mesh of the required size off the roll - enough to cover the whole surface
being plastered - before you begin plastering.
Apply the basecoat plaster to approximately half the total desired thickness.
Stick the mesh to the wall by holding it in place (often easier with two people) and
smoothing it with your gloved hand into the wet plaster.
The mesh should readily stick to the plaster, but if it looks a bit loose, rub it with a
gloved hand so that it sinks into the basecoat a little.
When all the mesh is in place, apply the rest of the basecoat over it.
If the total area of the panel needs more than a single piece of mesh to cover it, overlap
the mesh pieces by at least 50mm to avoid creating a weak point where the two meet.
Pieces of mesh can also be used in the plaster at the usual stress points, for example at the
corners of window openings (see Figure 12 ) , and where different substrates meet, such as
at a cross-over between hempcrete and wood wool board. The orientation of the mesh is
important and should follow the line of the expected stress fracture.
