Why does the wood turn gray ?
All types of wood will eventually turn gray or “weather”. Sunlight is the main cause of “weathering” and can be slowed down by treating your wood with a penetrating stain that contains UV blocker-“suntan lotion for wood”. It is not necessary for the stain to have waterproofing capabilities unless you have a sprinkler system that keeps your fence wet. These stains can be found at any home center and are available in clear or colors. It is wise to stain a picket or two before you buy a lot of stain to make sure you are satisfied with the color.
