Painting inside a fireplace

Hello all

I am helping a friend to decorate and am currently looking at how to paint inside the fireplace back wall, mix of bricks and stone.

I have cleaned the back wall with some nasty chemicals but there is still soot residue :anguished:

Does anyone have any idea of what paint to use please? I am also toying with the idea of using some large floor tiles to cover the back, thoughts, ideas welcome :slight_smile:

Is it ever going to be used as a fireplace again? If not and it was mine I’d seal it off top and bottom and line it with plasterboard or plaster it and paint on top.

If it is planned to use as a fireplace, then you will need to use a stain block paint to stop the soot, followed by heat resistant paint. I forget what the stainblock is called here. it’s hideously expensive but works a treat…a workman forgot to put the top on the oil tank on his compressor and sprayed mucky oil all over one of our new walls. So no matter how much we washed it we could still see the stains. One coat of stain block and as good as new.

If you are thinking of tiles then again be careful about heat, as some tiles won’t resist high temperatures. We put a new stove in one room, and lined the wall behind with the stones tiles we used on the floor (and before someone protests the wall was already insulated with fireproof insulation). You can also use porcelain tiles made for fireplaces.

I am not sure if they have such a thing in France, or how effective; but I would be tempted to find a sand blaster machine ( or equivalent), to clean the brickwork and if necessary repoint…not even sure if there are services such as these in France.
Call me crazy, i’m just a lover of nice features and stone / brickwork…
cover it all up …sacrilege , but there are many things I don’t quite get about the way buildings are treated in France.

Aéro gommage…it exists but also v expensive. Sablage is the sand equivalent but rather harsh.

Hello Véronique, it is still going to be used …:anguished:

Thank you Jane, I will investigate further with stain block :slight_smile:

Hello Glenn, yes there are sandblaster services here, the problem is it isn’t my house, I am trying to do as much as possible on ‘a shoestring’ for a French friend who has a very small budget ! :thinking:

This is how it was before I started …

Yes that’s me, doing the best I can, note that afterwards I had already covered the hole in the wall and ‘constructed’ a new wall over it. The back of the fireplace is driving me nuts though ! :angry:
Plus all the brickwork that supports the mantle was covered in mauve paint, not now though :nauseated_face:

How about something like this


These are tiles from bricodepot, covers up loads of sins


B’, my Wife painted tiles with paint, for ceramic tiles, fired them in our oven, they are on the wall behind the woodburner (for several years), very effective.


Next time I am in our ‘big town’ I will price up tiles. Think that it may be the best solution, thank you everyone who replied :slight_smile:

Having the bricks in their “original” sate would look good. Sandblasting probably too harsh and I suspect pressure (water) cleaning would not be a good idea indoors - have you tried detergent and a scrubbing brush on a small area?

Hi Paul, yes I have tried detergent and even some ‘harsher’ chemicals because, like you, I believe the bricks would look good in their original state, alas nothing works :frowning:

If you do use tiles Ann, make the gap between them wider than normal, and use grout made for the purpose, it’s flexible, so will tolerate the expantion of the tiles, with heat :slightly_smiling_face:


Ann, before giving up hope, try some oven cleaner, used for cleaning gunk built up on ovens it worked very well on our lime stone and left some character behind. Sorry I never thought to take a picture before and after.

I use woodash to clean burnt on stains on glass and aluminium, it might be worth trying it in the bricks as well.

The slate tiles don’t need any gaps, they fit together with a “step” at each end. Effectively, they are 4 strips of slate, 2.5 cm wide, 20 cm long glued together. As long as the surface behind is sound, normal wall tile adhesive works.

Muriatic acid should do it, eventually.
