Have a light switch unit that is falling off. The screws are not tightly installed as the area under it is not uniformly solid, damaged and has many holes. What's the best fix to repair that section of ceiling making it solid and effective for screws. I have Gorilla mesh tape but would I need some strong adhesive or something more solid to strengthen the area? Any help is welcome.
>>2976643you cant have a pull switch mounted on just plaster the screws need to go into wood.so you need to know if your ceiling is plasterboard or if its lath and plaster. if its lath you can just screw into a bit of wood thats there, maybe rotate the switch a little bit.if its plasterboard then you need to get some wood up there to screw into. ideally the wood is secured to a joist or roof member.as for making good the ceiling, get the switch out of the way, then sand/filler/sand/filler/sand/filler until you are happy with the bits you will see then paint. just use ready made filler don't bother mixing plaster for such a tiny area.the condition of the plaster should have nothing to do with how secure the switch is, the screw should clamp the switch to the wood and crush anything between into compliance.
>>2976643stuff old holes with matches, do not forget to strip the chemical tip. increase contact patch
>>2976648Thanks. It's plasterboard. But how do I get some wood up there in such a confined space?

>>2976657Replace the switch with a remote relay module and hide it in a junction box in the ceiling. Then patch and paint.
>>2976657You're near a wall. Two walls. Those will extend a bit above the plaster. You can screw a block of wood into those beams at an angle. Tuck it all up inside the ceiling. Then repair the plaster so it's invisible.
