I bought a house this spring that includes a tiled stove from the 1920s. It's now getting close to starting up this heat source. It has been used continuously in recent years, according to the previous owner (inspection exists). He also mentioned that one should maintain the fireplace by adding material around it as the clay cracks a little when used.
From what I understand, it's a type of heat-resistant clay that should be "built up" with. Is there anything to consider when purchasing it, and how should one go about applying this? How often should it be done? Grateful for any tips.

You need regular, honest dry clay (alternatively, dig up your own from the ground). Unfortunately, it's rarely available in hardware stores, so find your nearest building conservation store or stove maker, or buy from Bara Mineraler.
Remove all loose plaster, wet the stones.
Mix about one part clay and three parts sand (fairly fine-grained) with water into a loose mortar.
Apply an even, thin layer, a few mm thick, with a sponge or brush.
Let it dry for a week.
How often depends on how much you fire, but maybe once a year. You'll see when the plaster disappears.

Thank you for the response.
A few days ago, I also got in touch with a kakelugns renoverare through acquaintances who mentioned the same things. He specifically mentioned that one should not use anything other than regular clay, as heat-resistant clay often becomes too hard and cracks more. This has probably been used before.
I will receive the clay next week.
