Related to Burma teak, this hardwood grows naturally and plentifully in the Pacific Rim countries. Because shorea is dense, heavy, and hard, and contains an abundance of natural oils, it is highly resistant to rot, bug infestation, weather, and marring. Shorea (red lauan) wood will have variations is color - from a red to a yellow cast. The Shorea wood for this item is treated with linseed oil. Linseed oil is not a varnish. The oil soaks into the pores of the wood leaving a shiny (not glossy) surface that shows off the grain of the wood. Linseed oil helps protects the wood from denting by compression and from accelerated deterioration. After assembly simply wipe the bench with a damp cloth to remove any excess oil that may be remaining. Please note that it is recommended to let your bench sit outside for 2-3 days before sitting on it to let the stain air out and completely dry.
