Filling large hole in chimney breast

doryfish

Hi all. I've just moved and where the previous owners had a big plasma telly fixed to the wall, it's left a big round hole going through the entire layer of brick into the flue for the chimney. There is also another hole covered by a brush plate that I think they had the wires fed through. I have no intention of hanging the telly on a wall so want to make these holes good. Could anyone tell me the process for doing this correctly?

What I would do:
1. remove all dust
2. fill with a good quality filler and over-fill the hole
3. sand it down to smoothen the finish
4. paint over

If it is a very large hole, filling can best be done by using a piece of brick (or a bit of concrete) and bedding that into some filler or mortar set a few mm back from the surface. Then make up to the surface with filler or plaster to finish.
You will find that filler alone will slump unless you do it in a number of stages.

It is quite a large deep hole and because it goes into the flue then I'm sure filler would as you say, slump. The brick and fill option sounds sensible and doable. Thanks for the tip tony6403.
