Clear deck sealant is the perfect way to protect and preserve outdoor decks. This water-based sealant penetrates wood fibers to form a tough, durable barrier that resists damage from UV rays, moisture, and extreme temperatures. It’s easy to apply and can be used with a brush, roller, or sprayer. It also resists mildew and mold, making it a great choice for humid climates. It dries quickly and will provide a clear finish that won’t darken or yellow over time. For best results, apply two coats and let dry for 12 hours before using the deck. Clear deck sealant is a must-have for anyone with an outdoor deck!
