Does it not say on the box ' mix tiles before laying' or something along those lines ?
Or does it say
'Please check every tile next to every other tile due to shading issues' or something along those lines ?
I know we mix boxes up when laying ,cos I'm sure that's what I've read ? But that's a s far as I will go .
I personally do not know ONE person (in GB) who will check every tile on every job next to another tile , it's even, dare I say it , ridiculous to even suggest it .
I don't know how tiles get quality checked , Shirley they must do somewhere along the lines before being shipped ? So Shirley it's not the tilers fault if they are wrong , it goes back to the maker, importer,then supplier then last but not least maybe the tiler.
I actually can't believe that people on a tilers forum are blaming a tiler for fooking shading issues , it beggars my belief 😉
