01
Apply joint tape
Apply professional plasterboard
self-adhesive fibreglass joint scrim to the
speaker face. Ensure it covers the entire
speaker face and the plasterboard joint.
Amina can provide rolls of 500mm wide
adhesive scrim to do this in one operation.
Alternatively, use multiple strips of narrower
scrim tape.
This provides increased surface area for the
plaster skim coat to bond to the panel
surface.

Clean Speaker Surface
Clean speaker surface of dust and grease
with a solvent wipe or damp (not wet) cloth.
Ensure that silicone sources have not been
used in the vicinity.

Plastering and decorating
01 Fill gap between speaker and surrounding
area
It is important to ensure that plaster is
pushed into the 2mm (5/64”) gap that
surrounds the speaker. This will create a
strong bond between the edge of the
speaker and the edge of the plasterboard or
render and will prevent any cracks
appearing in the skim finish.
Use a low shrinkage repair plaster such as
British Gypson Easi-Fill®.
IMPORTANT: There MUST be a gap of 2mm
(5/64”) all the way around the speaker edge.
If there isn't simply remove the speaker and
increase the aperture size accordingly.
