What is the difference between a seal and a stain?
A seal is an oil based penetrating clear finish applied by spray that protects against water. It has no UV protection. We guarantee it for 12 months. A stain is an oil or a water based finish that contains pigments. A stain protects your deck from water and provides UV protection. The pigment in the stain allows the deck to look better, longer. Because decks are different ages, species and quality of wood and have received differing amounts of care, sun and shade. They will absorb the stain differently. A clear stain has no UV protection in it. If UV protection is needed then a colored stain is required. The darker the stain color the more UV protection it has.
