ᐅ Tiling over expansion joints

Created on: 27 Jun 2019 07:40

Hello everyone,
wood-look tiles will be installed in the open kitchen, living, and dining area on the ground floor. There are two expansion joints throughout the entire ground floor. How would you handle this? Is an uncoupling membrane necessary, or should the tiles at the joints be connected with silicone? I would appreciate your feedback.

Interesting topic. What happens if the screed grid spacing becomes too large in both directions and expansion joints are installed at a 90° angle to each other? In that case, the wood-look tiles mentioned above can only be aligned with one of the two joints, while the other joint will cut through the installation pattern. :-( Therefore, I would also appreciate good ideas regarding Iasa64’s question.

We have an expansion joint running across the tile pattern (originally, no tiles were planned), and I was very worried that it would look bad. However, if the tile installer works precisely and the colors are well matched, it does not seriously bother me. At least it doesn’t bother me, but of course, that might be a matter of personal taste!

Thanks for the photo. It really looks quite unremarkable, I expected it to be worse. So it will probably look like this in our place as well: the transition between the hallway and living room will have this appearance. It should be fine!

Should the uncoupling mat (reinforcement mesh?) be laid across the entire surface or only in the area of the expansion joints?

Thank you for the many responses.

In which direction would you lay the wood-look tiles on the ground floor? Which option looks better?

That depends on the lighting; in your case, with the image above, the installation direction would be perpendicular to that, which also depends on the tile size. With 60cm x 60cm (24 inches x 24 inches) tiles, it probably doesn’t matter.

This would likely benefit the room by giving it a visually wider appearance.

Yes, for aesthetic reasons, I would prefer not to have longitudinal joints that would make the room appear even longer. So I would also be in favor of transverse joints.
