I have recently had LED down lights installed in my ceiling.
In strong winds I am finding some granulated loft insulation is blown through around the light fixings.
I would like to seal around them – what should i use to do this?
Silicone would be hard to paint. Would decorators Caulk "stick"? any advice appreciated i am in UK.

There are ‘paintable’ silicone caulks, if the gaps are not very large that may be a good choice. Look for that keyword when selecting. You could also use drywall paste (plaster? Not sure of the term in UK) If you need flexibility, like if the fixture may move relative to the ceiling, silicone is a good choice, but if not and it’s only small gaps (<=10mm) them maybe a latex caulk, paintable again. For larger gaps you’ll want to fill them first. You could use something like butyl cord or strips, but push them up above the surface because they won’t hold paint, then cover with calk or plaster.
