silicone sealent around downlights

[kevin_robson]

We have GU10 downlights in our bathroom. Unfortunately the electrician has drilled the holes in the ceiling ever so slightly too big for the downlights, so when they are on you can see the light coming through between the plasterboard ceiling and the light fitting.

I was thinking of putting a bead of silicone sealant around the light to block this and make it a bit neater.

I'm worried about the heat though. Has anyone done this, and is there any special heat-resistant sealant available.

Hope this makes sense.
Thanks

Ps if its a big hole change downlighters to the tilt variety the hole is bigger.

silicone will still let light through

assuming theres a lip on the front edge to hide it could you not wrap heat proof tape around to increase the diamater of the fitting!!!!!!

White silcone will, but what about black?

Trouble is it is very difficult to paint silicone.

painted decorators caulk or normal filler tends to be ok for small gaps.

Personally, I'd go round and kick the lobbocks off the spark. T*at!

i reckon a decoraters caulk is your best bet

Will see what I can do with the sealant. My main worry was the heat buildup.

I'm in the same situation I'm worried about using silicone and the decorators caulk sounds worrying as well. Does anyone have any other suggestions?

use filler to patch the gap. just trowel it in round the edges and let it go hard..

Fill the holes and start again, this time finding an electrcian who'll cut the holes out the right size by hand, not just using the nearest sized hole saw he can.

 

[kroc_kroc]

The holes were the right size. It was me who damaged some of the edging when I was painting around the edges. Out of 6 lights I need to try and "make good" 3 edges where the plaster/paint is chipped (by me). I was thinking of using silicone but as i said i'm worried about the heat – what's the best thing to use that not going to burn or smell.

I would say Tim77's advice is best if not coljac
