How often should I stain my deck to ensure it remains both aesthetically pleasing and protected from the elements? Is there a specific timeframe that I should consider for reapplication, or does it depend on various factors such as the type of wood, local climate conditions, and the quality of the stain used? How does the exposure to sun and rain affect the longevity of the stain? Moreover, should I be vigilant about checking for signs of wear, such as fading, peeling, or a rough texture that might indicate that the protective layer is diminishing? What are the recommended practices for maintenance that might extend the life of the stain? Could it be beneficial to consult a professional for an assessment, or is it advisable to rely on my own observation skills to determine the optimal time for re-staining? Finally, what are the consequences of neglecting to stain my deck regularly?
