Retrofit / pre-skimmed plasterboard
Feathered skim finish
For walls /ceilings that have already been plaster
finished.
Speaker alignment required for plastering
Using a 2-3mm shim set (contact your Amina
supplier) 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 (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®.
