First: Cut around the hole with a Platerboard keyhole saw so that the hole is either a square or a rectangle.
Then: Measure the hole and see if it’s next to any wall studs.
Next: (If there is a stud ignore this step.) If there’s no stud, measure and cut two small pieces of wood, around one and a half times the size of the hole. Place the pieces on the inside of the wall, perpendicular to the floor and parallel, on either side of the hole. With plasterboarl screws, screw in the top and bottom of each piece through the outside of the wall.
After: Cut out a piece of plasterboard that is the size of the hole. Fit it into the hole, and screw this new piece into the backers you have just created.
Finally: Cover all the screws you just made and the joins with F.G Tape. Then you are ready to finish up. Apply Boral Patch Cote 20 with your Broad knife, let it dry, sand down, and then prime and paint.
