Deck stain and sealer serve basically the same function: to preserve wood and protect from moisture and the elements. A deck is exposed to wind, rain, and UV rains all year long. Moisture can lead to fungal and mold growth, and it could rot the wood. Protecting the deck from moisture intrusion can lengthen the life of a deck, and it can prevent individual boards from rotting which could create a safety hazard. A deck sealer is a transparent or clear finish that either forms a clear film on top of the wood or penetrates it. A deck sealer does a great job at protecting wood from moisture, but does not protect it from UV rays.
Prolonged exposure to UV rays dries up the wood’s natural oils causing cracking and splitting. Deck stains have the same moisture resistant qualities as deck sealing. However, deck stain has added pigment. This color is partially transparent which gives deck stain an added UV protection benefit.
