I’ve just had some kitchen lights installed on a recently plastered ceiling and now have a bit of making good to do as the holes left by the plasterer did not match up with holes the electrician made. For small bits this is not a problem as I’ll use some filler but one of the holes is quite large and was wondering what the best way to fill this would be? Thanks

by the way they are self adhesive and stick to ceiling then fill with thin coats sanding inbetween.

When electricians drill the hole for the recessed lights in the wrong place I keep the bit of plasterboard.

I then take two thin strps of wood and insert them into the hole. I screw from the underside so the that the screws go through the ceiling into the wood above (pulling the wood down tight).

Now the hole is nearly filled. I then squirt some caulk onto the reverse of the round plasterboard and push it up.

Finally I fill the remaining gap and the srew holes.

If you dont have the old pasterboard you can use mdf, timber or lots of filler.

The same technique applies for any hole that you have that is wide enough to put the timber into.

I agree with Opps,, this is the best method,, stronger too!!

Instead of using screws wouldn't it be possible to "stick" the piece on using something like "no more nails"?

certainly would - stick the wood across inside the hole - leave to set - stick the p/board up to it

Agreed, sometimes I do that but often the top of the plasterboard is dusty- depends on the age of the ceiling.

You can also force more plaster out or at least crack more of what surrounds the hole.

Had a chance to have a look in more detail today and couldn’t remove the light. I thought about giving it a good old yank but then thought better of it. So, looks like I’ll have to fill while the light’s still in place. Great!!

So you mean that the holes are larger than the lights? And that the lights are pushed to one side?

Often the lights have two sprung loaded wings that hold them in place.

Pull the light down slowly, the wings will invert under pressure to allow it to pass through the hole. WATCH your fingers though- think mouse traps.

Once down to can run a bit of wood where desired to help hold the filler.

The holes for the lights are about 75mm in diameter. On the side of two of the lights there is a hole, about the size of a fifty pence piece, and this is what I need to fill. Yes, the lights have springs on either side and I can get them down as far as the spring hinge(?) but no further as the hinge is getting caught in the side of the hole. I’ve tried rotating the lights to free the hinge but this is difficult as the lights have transformers attached on the top of the lights at a right angle. Above the ceiling is the insulation board and there can’t be a lot of room to twist the light. Hope this makes sense?

They went up so they will come down. If you fill them with the lights in situ then if the need to remove the lights arises you will damage the filling.

The transormers are very reliable but they do fail from time to time.

if you definately don't want to pull the lights out then use RedDevil OneTime, fill as best as you can then refill the nest day

Car body filler is best. No waiting around and it's tough but sandable.
