attaching light fixture to ceiling rose

[sannesley]

I have a 53cm cantebury plaster ceiling rose which I will fix to the ceiling using coving adhesive. On top of the ceiling rose I want to mount a pretty flush and light light fixture with 3 stems for lights coming from the centre of the light.

Is it standard practise to mount the light fitting to a ceiling joist above the rose? This would require pretty long screws and might mean lifting the floor in the room upstairs to see if a support is needed for the light fitting. Or could I mount the fitting to the ceiling rose in any way??

the ceiling rose or the hook/mounting plate for the lamp should be attached to a block of wood or the joist. You will quite likely have to lift the floor above to see what you are doing (unless there is already a block that you can see and screw into)

Otherwise you will be expecting the plaster to carry the weight of a heavy lamp. Which it will not do.

That's what I originally thought John. I just wondered if there was an easier way that wouldn't involve lifting the floor in the bedroom upstairs as it's a pig of a job as a lot of stuff will have to be moved out of the room.

take off the old light fitting. Look through the holes, and poke with a non-conductive implement to see if there is already a block there.

A pendent is quite likely to be adjacent to a joist, or have a noggin.

I expect this plaster rose is a fair diameter, so make a hole in the ceiling to see what you are doing first!

Most people stick these up with adhesive, but also use two screws into a joist to hold weight while it dries - These screws can be recessed slightly and filled/painted.

you could use these if they are long enough http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=100067&ts=04699&id=31268
