4 A few words about wood Wood is a living organism. It breathes, has juices and is sensitive. It can be hard like teak, oak, exotic iroko, or soft like pine or fir. You may enjoy its beauty for many years as long as you taking care of it. Moisture and water Whether indoors or out wood does not like moisture. The industrially processed lumber has been dried before being sold. However, both storage conditions and the subsequent exposure of wood surfaces to moisture can affect their ‘health’. In any case, the moisture of the wood mass should not exceed 20%. Intense sunlight Ultraviolet (UV) radiation negatively affects wood surfaces, initially creating ‘wrinkles’ and then grooves in the surface and even the mass of the wood.
