‘Wet Paint’ translates as ‘Péint Fluich’ (focloir.ie does give 'seachain an phéint!’ which probably translates as ‘Avoid the paint’).
‘Fresh Paint’ translates as ‘Péint Úr’.
Therefore the mathematician in me can understand that ‘Péint Úr’ conveys the same meaning as ‘Péint Fluich’.
But the me that is trying to improve my Irish cannot agree with Dulux paints (and Collins Gem Irish Dictionary) that ‘Wet Paint’ translates as ‘Péint Úr’.
