This deck is the first deck we sealed for the 2015 Season. The start dates all depend on weather (dry, moisture level, temperature). This deck was built around a pool with treated decking and railing in Fall of 2014. We applied Penofin Sealer on it mostly because it will be a better product than most around a wet and moist area (Pool). Now the homeowners just need the water to warm up so they can enjoy the new sealed deck with the pool.
