Feathered skim finish
BackboxCV alignment required for plastering
Using a 2-3mm shim set (contact your Amina
supplier) between the back of the speaker
and the speaker mounting lip , the front
face of the speaker should be flush with the
front face of the existing painted/plastered
wall/ceiling.
This method positions the speaker so that a
much larger area around it (approx. 1m
2
(39”)) can be skimmed. This 2mm (5/64”)
thick skim is then feathered outward at the
edges and blended into the existing
wall/ceiling finish.
