Hello.

We are preparing for our new wood-burning stove and need some advice on laying tiles.

1. Parts are a cast foundation, the rest is particle board. The concrete has been chipped down to the same level as the particle board but isn't smooth, with some dips and such. Is it sufficient to lay renovation plaster as a surface for the tiles?

2. If renovation plaster doesn't work and leveling compound is the solution, should there be a gap left against the parquet and wall (plaster) or can it be filled all the way to the edges?

We don't want to build too much height, is reinforcement and about 4-5 mm of leveling compound enough? The idea was to lay tiles across the entire surface and the wood-burning stove is a Contura I51T, weighing 345kg + heat storage of 100kg and smoke pipe on top (single-story house) so it is quite a load. We will also cut the floor a bit more so the hole will be about 140 wide, 120 deep of which 30 cm on each end will have particle board at the bottom.
 
  • Concrete and chipboard floor area cut out, with exposed pipe against floral wallpaper, showing uneven surfaces prepared for tiling installation.

Does laying renovation gypsum as a surface for tiles hold?
No.

Thanks, it was already ruled out but it's good to have someone confirm my suspicion 😄
