Height difference chimney/wall during tiling

[Mgns L]

Hi! I’m planning to tile one of the walls in my 1930s kitchen completely. One corner is concrete due to the chimney stack, and the rest is made of solid wooden planks (I’ve already removed all the masonite). There's a level difference between the wooden wall and the chimney stack. The size of the level difference will be 3-5 mm once the plasterboard is applied to the wooden wall. So, the plasterboard sticks out that much. This means that I need to apply something on the chimney stack to compensate for this, right? Can I glue a board to it? Or do I need to add some kind of layer of something? I want to do this properly but need to know how. I have no experience with this but want to do it myself.

Post a picture. A picture says more than... 😁

Here is the image. I am talking about the vertical level difference. Not the horizontal (even deeper) level difference visible in the image. The vertical one is, without having removed the masonite here, about 3-4 mm. If I remove the masonite (5-6mm), the plasterboard that is 13 mm will stick up by a millimeter or so.

So you're planning to place a plasterboard in the green area?

The vertical is approximately 3-4 mm without having removed the masonite here. If I remove the masonite (5-6mm), the plasterboard, which is 13 mm, will protrude a few mm.

On the yellow area, if I understood correctly

Here is the picture. I'm talking about the vertical level difference. Not the horizontal (even deeper) level difference visible in the picture. The vertical one, without having removed the masonite here yet, is about 3-4 mm. If I remove the masonite (5-6mm), the plaster, which is 13 mm, will stick up by a few mm.

If there is plaster behind, you can level it with gypsum mortar.

Yes, everything should be plastered except for the part at the bottom TV that won't be visible behind the stove etc. The yellow area.

So I was planning to put plaster and tile the yellow area, not the green-blue one.

I don't really understand the problem, level with for example gipsbruk as already mentioned and then mount drywall over everything, wouldn't that be good?

I don't really understand the problem, level with something like gypsum burn and then put gypsum boards over everything, wouldn't that work?

Yes, that might be the solution. I guess I’ll have to venture into yet another unknown world – casting gypsum... How do you make it as smooth as the rest? A giant putty knife? Is it difficult?

You don't cast plaster; it comes in powder form that you mix with water and then apply it like putty and align it with a straightedge or a straight board to achieve a flat surface on the wall...

So a mortar tub, a trowel, and putty knives of about 15cm and 25cm are what I usually use…

Thanks!

If you apply plaster over the entire wall, you can dab some plaster mortar on the chimney breast to act as glue for the plasterboard on the chimney breast. The rest of the plasterboard you screw in. That way, you don't have to try to get it level with the rest.

Thank you!

Don't mix too much the first time as it sets quite quickly, but gipsbruk is easy to scrape if it's half-hard and bränner ifrån dig…
