What to put over old internal chimney surface

clivej

I'm installing a new kitchen in an old house. I've taken out a very old coal fired range. I have cut out above the old range and put in a lentil for support.
What I need to know is how do I get the tar, soot off the inside big flue wall before plastering?

I presume the fireplace is not longer used?

Why not just put up studs and board it over.

That's what I was thinking of doing.
I still have to chop out the tapering parts of the chimney to make room for the extractor fan

id board up the whole thing tbh. Saves trying to correct the scratch work above the lintel. unless your stuck for the space .

An oven and the hob with overhead extractor fan are going in to the place where the range was.

I didn't meant board over the hole. Just meant as per the image attached above.

It's not the outside walls or lentil of the range that I need to sort out, it's the inside aera of the old chimley stack.

I'm now thinking of covering it with expanded metal, going over with a coat of bonding and then a skim finish.

Tile over it all then to hide all my mistakes. :eek: :eek:

To my untrained and non-engineer eye that does not look like a lot of timber to hold up a chimney? A nice solid lump of larch or oak or something about 4 times as thick as the bit in use, slotted into the uprights might make a better lintel?

I think your confused about what im saying.

Inside the Chimney just stud the wall and board it. That doesn't mean cover the cavity . On the outside glue new boards up over the wall area. Again not covering the cavity.

He's evidently cut out the wall and put a proper lintel in. Be has then put some small timber up to stop the concrete scratch coat falling down until it dries. The lintel is under the concrete scratch coat you see.

Ah yes, thank you, I see now that there is in fact a shape where a lintel is! I will retire quietly into my corner again

Your correct.
Bit of 2" x 1" is only there as an edge to work the scratch coat to. There is a lentil holding up the wall above.
Sorry photo's are side ways.

If you saw lentil that came out, this 100 times better and will last as long as it will ever need to.
The stack only goes as far as the second floor where it then moves to the left and joins up with a lounge chimbly

Can you wrap the inside of wall with cement board and tile over instead of mesh bonding and skim and less hassle as long as walls are fairly straight

I think the poster was making light of predictive text or something having the structure being supported by a lentil rather than a lintel.

I'm all for promoting vegetables and pulses but this would be too much:)

Finished now.
I put expanded mesh on the wall, fixed with washered steel nails. Then a layer of bonding followed by a plaster skim coat. Not the best of a finish but it was going to be tiled over anyway.
