I need to fill in a section of plasterboard approx 1 inch x 8 inch. I have had some electrical work done and the sparkie had to route new cables to a fan isolator switch. I told him to just cut a channel in the wall to lay the cables as we are re-decorating the room. It's on an external wall, the current plasterboard is just dot and dab onto the blockwork.
What is the best adhesive to use to stick a new piece of plasterboard in this channel?
Thanks
