Abstract

A set of moisture proof floorboards and a flooring of such floorboards with a resilient surface layer provided with a decorative groove and/or a sealing means.

Claims

1. A set of essentially identical moisture proof floorboards each comprising a front face and a rear face extending in a horizontal plane, a core, a connector arranged at least at two opposite edges for connecting one of the floorboards with another floorboard in a vertical or horizontal direction, and a resilient surface layer,

wherein at least one edge of each of the floorboards comprises a decorative groove in the resilient surface layer with a bottom which is essentially parallel to the front face.
