Old Grey - as the name so the character: a floor in the trendy "old floor appearance". The basis of this design is a distinctive Oak. The design is planked. The cathedrals and the harmonic ingrown knots accentuate the natural structure. A slight coating - like a patina - forms the special character. This slight film lets the multifaceted structure - sometimes more, sometimes less - show trough. This leads to the typical "used look".
