The deck’s flooring should be strong, easy to maintain and provide adequate grip. Deck flooring is an important aesthetic feature as it is the most visible part of a deck. It must also be able to withstand abuse from furniture, walking and weather.
Wood deck floors often expose the bark side which is normally the more attractive side so that the ring and grains are visible. Also, the bark side has a better ability to hold water which will prevent unwanted warping.
