remove Mexitegel from chimney + new finish?

[albinivik]

Hi!
The chimney in the basement has really shabby plaster + an additional row of mexitegel on each side. What are my options for finish once I've removed the plaster and mexitegel? Is it easy to renew the mortar and make the surface nice for a "bare" finish?

And I assume that the mexitegel doesn't have any load-bearing function since nothing rests on top of the stones + the rest of the chimney on the ground floor and attic doesn't have these mexistenar.

You seem to have started well. Continue tearing down mexitegelpåbyggnader and the like. You'll probably need to seal up some holes as well, consider if you want a sotlucka there to access the channel. It's almost a requirement if there are fireplaces connected higher up. Get a gastight hatch, there are various cast iron ones available in the market.

And replaster. Buy bagged plaster and follow the manufacturer's instructions. The most important thing for getting it straight and neat is to set up guides so you can level the plaster after applying it with a board. They can be made from wooden strips like before, or you can buy the ones provided for the purpose in metal from the market:

Half the job is setting everything up for plastering and covering and the cleanup afterward. The plastering itself goes quickly.

You seem to have started well. Continue dismantling the Mexitegel extensions and similar structures. You'll probably need to seal some holes too, consider whether you want a soot hatch there to access the duct. It's almost a requirement if there are fireplaces connected higher up. Get a gas-tight hatch, there are various cast iron options available in the market.

And re-plaster. Buy plaster in bags and follow the manufacturer's instructions. The most important thing for getting it straight and nice is to set guide rails so you can scrape off the plaster with a board after applying it. These can be made from wooden strips like in the old days, or you can buy the metal ones provided for the purpose in stores:

Thanks for the comprehensive response! I've now torn off all the old plaster and Mexitegel, should have covered everything properly beforehand because the cleaning took longer than the demolition. I guess it's one of those mistakes you only make once...

I'll probably need to hire some masonry help after all because I would like to move the pipe to the left side so I can have a new smaller stove next to it instead of the old one which stood in front. And then they might as well do the repointing and washing of the stones.
