Retrofit / pre-skimmed surfaces
Feathered skim finish

Speaker alignment required for plastering
Using a 2-3mm shim set (contact your Amina
supplier) applied between the back of the
speaker and the mounting surface of the
backbox (or fixing blocks), the front face of
the speaker should be flush with the front
face of the existing painted/plastered
wall/ceiling.
To feather finish:
Allow a much larger area around the speaker
(approx. 1m
2
(39”)) to be skimmed. This
1-2mm (5/64”) thick skim is then feathered
outward at the edges and blended into the
existing wall/ceiling finish.
Amina recommend British Gypsum Easi-fill®.
