Hello everyone,
Today our floor installer started laying Italian Ardesia slate. The calibrated slate slabs are sized 50x100cm (20x40 inches) with a thickness of 2cm (0.8 inches). The surface is brushed, so it has a relatively fine and consistent texture. The slabs are laid like tiles, meaning they are not staggered.
After the first rows were installed, we noticed that the top edges vary by up to 5mm (0.2 inches) from tile to tile, sometimes at the corners, sometimes in the middle.
We were then told that this is completely normal because slate is split, not sawn. Therefore, achieving a perfectly flat surface would be impossible.
The worker himself said the job was a mess and that it looked as if he didn’t know his craft!
We also think it doesn’t look good and, in addition, the raised edges are very sharp and could be a tripping hazard.
Can someone tell me if this is really normal, or if there are any standards regarding the flatness of such floor coverings?
I would appreciate any feedback.
