Granite tiles on concrete floor?

Hello RobsonMKK

I received the tiles as a gift.
I will only hesitate to apply the leveling compound if it is professionally acceptable otherwise.

What does uneven mean? 5mm... ? Do you have an elevation somewhere that might only be 5mm high but cannot be detected by you? Then this happens: For example, you start tiling on the left and want to work your way to the right, applying the adhesive about 3mm thick and laying the first 2 tiles. The unevenness makes your tile surge up like a seesaw, making it impossible to lay.

I only say thick-bed, not adhesive

The man is right. That's how it's done.

I only say thick-bed, not glue

As a layman who has already correctly and levelly laid 30 cm tiles in a 50 sqm living room, I would not dare to do thick-bed.

Certainly, but then he cannot avoid using leveling compound, and it is not as simple as one might think.
