Fixing a dot and dab wall

[richie4236]

Recently had electricians in, running thick cables for power showers.

The route they took meant chopping a section of plasterboard to reveal the breezeblock wall beneath.

The work is now complete, and I'm ready to close the wall up, but I'm not sure the best way to do it. I've fixed stud walls before and used a variety of fillers, but this is clearly going to need more than a tube of Polyfilla.

The cut is about 6cm x 250cm and I'd like to have a finish I can paint on when we decorate the room.

Any suggestions on the best way to do it would be appreciated.

Cut it square with a Multitool then expanding foam a piece of plasterboard in, possibly use a piece of 9.5mm board if the cables stick out a bit then fill/tape the joins.

If your having the room plastered then a bit of multi finish.
