Difference between angle profile, square profile, and cube

Good morning everyone,

The tiles have now been chosen (90 x 90; 10 mm thick) and I still need black rails. Therefore, I have the following questions:

1. What is the difference between L rails and square rails?
2. If you use square rails, do you then need this end cube?
3. If my tile is 10 mm, then I need the height of 11 mm from the rail, right?

Thank you very much.

1. What is the difference between L profiles and square profiles?

The L profile finishes the transition between tile / plaster when the plaster is flush with the tile; if the tile overlaps the plaster, you use square profiles.

2. If you use square profiles, do you need this end cap?

Yes.

3. If my tile is 10 mm, then I need the profile height to be 11 mm, right?

That’s how I understood the explanation as well.

3. If my tile is 10 mm, then I need the height of 11 mm for the rail, right?

If you lay 90x90 tiles, you get a solid adhesive application (buttering-floating method). Then the tile with adhesive can also be 14 mm or more high. Will 11 mm rail look good then?

1. What is the difference between L rails and square rails?

One is L-shaped and the other is square ;)
You can use both as finishing at practically all places. Whether transitions or corners and edges. Whether tile to plaster or tile to tile. It's purely a matter of taste. L-rails are noticeably more delicate.
