Unfinished White Oak Flooring: Uncovering Natural Beauty and Endless Possibilities Unfinished white oak flooring refers to hardwood planks made from white oak trees that have not undergone any surface treatment or finishing. Unlike prefinished flooring, unfinished white oak planks provide a blank canvas for customization, allowing homeowners to stain, seal, or paint them to match their unique style preferences. A classic example of unfinished white oak flooring can be found in historic European castles and cathedrals, where the natural grain and warmth of the wood create an inviting and elegant ambiance.
