Hello chaps. Need some help. I installed some of the above in light beige about this time last year to a reception area they asked me this week to follow on from the reception up the stair case this week and the colour is different massively to the point where the client thinks I've ordered the wrong colour which I haven't. The area gets a bit of sun which I know can dull the floor but her argument is its not gone that way down the corridor where there's no sun light. I also don't think a batch would be out this much the old floor looks more white than beige. I'm calling altro Monday but any suggestions? There also cleaning with normal floor cleaner.
