Will shortly have 6 inch diameter holes to fill in on ceiling when I remove halogen light fittings. I will have access above and below.
My plan is `glue` a piece of plasterboard in the void to cover the hole and then a 6 inch piece to flush it with the ceiling from below. My question is...
Do I then just use a filler to fill any gaps or should I be doing something else, I ask because I dont want cracks appearing later on.
