Tiles in kitchen - screed/connection to living room with joint problem

Hello everyone,

I am currently renovating my kitchen. While preparing the floor for tiling, I came across an unsightly condition of my screed.
Apparently, there is a screed joint adjacent to the living room – I assume it is the living room screed that still extends up to the inside of the door frame.

I know that the old tiles had a silicone joint exactly at that spot. It didn’t look too bad since the tiles were very small.
I will be installing 60x60 porcelain stoneware tiles.

Now to my question: Is there any way not to lay a 5cm strip of tiles there and to "decouple" the whole thing with a silicone joint? It would fit perfectly with a whole tile pattern.

My bricklayer friend told me that you could stick tape like duct tape on the strip and then just tile over it. Of course, without any guarantee... I understand that.
I was thinking about some kind of fabric that I could integrate. But I am not sure if that would really hold. There is underfloor heating underneath!

Is there a professional here who can give me a tip? I know that if you strictly follow the regulations, the only way here is the silicone joint.

Many thanks and have a nice evening,
Raphael

I would simply continue the tile through this small section. If it should crack for any reason, then replace it - so keep a spare tile.

I would just lay it over as well. Since you’re doing it yourself anyway, just set aside an extra spare tile in case something breaks.

You can resin screed joints, or at least cover them with fabric. Flexible adhesive is obviously a given. But of course, all without guarantee.

Thank you very much for the answers! Then I will just tile over it and put a piece of fabric underneath. It can't hurt.
Best regards

Hello " ". If the screed can be heated (a heated screed), which no one has asked so far, it must be treated differently than a non-heatable screed. If I interpret the photos correctly, it is a cementitious mixture in the door passage. Here are two possibilities: a) if the approximately 5 cm wide strip is unstable, meaning it crumbles under mechanical stress from a light hammer blow, then I would completely remove the strip, prime the exposed screed edges, and seal the entire transition area with a stable repair mortar. b) The movement joint has fulfilled its function after reaching the readiness for covering (of the old screed) and can be rigidly sealed in smaller objects where no major vibrations occur (such as in a hospital corridor). To do this, widen the visible joint to about 3 cm depth with a grinder (caution, please check beforehand whether an improperly installed line has been placed there), vacuum the fine particles, and rigidly connect the joint chamber with a reactive resin (do not use a viscous paste like polyester!!). Both of the aforementioned procedures are safe steps. Please leave out the cardboard and take the safe path as described above! ---------------- Good luck: KlaRa
