The Johnson Coastal Dune collection is a series of 7-1/2″ wide width oak planks that make up a very natural looking floor. This is an engineered hardwood with a 3/4″ thickness with random board lengths from one to six feet. The large oak planks allow the floor to expand and broaden any floor space. It has a light wire brush finish that is soft on the eyes. Its character marks and grain patterns add a sophisticated raw wood look. The Coastal Dune series comes with a low-gloss, eleven step aluminum oxide matte finish. This creates a sand swept, reclaimed look. This product comes with a thirty five year limited residential warranty and can be stapled, glued, or floated.
