In the pictures below you can see right at the top the brickwork that these 10ml plasterboard sheets have been adhered too. (Using specialist products)
Now the client did not want the added expense of calling in an Electrician or heat pump specialist to remove heat pump from wall.
So in this example we used specialised plastering beads as you can see around heat pump, to still provide a quality finish for the client at a significantly reduced cost, as no electrician was needed to remove heat pump and re-install from wall.
This is not the finished product as 2 x coats of plaster still remain and the cornice is yet to be installed.
But this is something to think about, an alternative that costs you as the client a lot less.
Regards.
