Pocket Door Plastering Problem

[Spinny]

We have an a Elisse pocket door opening installed for our utility room. This was chosen in order to create an opening in the wall without any architrave but with a pocket door - a clean contemporary look.

The pocket door metal framework from Eclisse has a plastering bead built in at the corner of the opening to support this look with plastered corners to the opening. It also has suitable roughened areas in the reveal inside the opening to allow plastering right around the corners and up to the slot where the pocket door runs.

.

However I now discover that this is positioned by Eclisse to support jointing and taping the plasterboard to a finish ! However we want and need to skim plaster onto our plasterboard and hence up to the corner of the pocket door opening. Hence it seems the built in metal plaster bead is not in the correct position to support this as it is level with the plasterboard rather than slighty proud of it by 3mm to support the skim coat.

 

So, how do I solve this ?

 

How much plaster can cover a corner bead when skimming a wall - can the plaster bead be 3mm deep beneath the plaster at the corner ? Or will it just chip and flake off ?

Could some special reinforced plaster be used in the corner area and blended into the rest of the wall skim ? Could some small 2-3mm corner bead be fixed/glued onto the eclisse metal frame at the corner ?

 

Anybody with experience of installing pocket doors without architrave ?

I'm not a plasterer but perhaps these would reinforce the corner..
