10 Best Deck Paint For Old Decks 2025 in the United States

The KILZ Low-Lustre Enamel Porch & Patio Latex Floor Paint in Slate Gray is a versatile acrylic latex product suitable for both interior and exterior use. It's specifically designed to provide a durable, long-lasting finish ideal for decks, porches, and patios. One of its main strengths is its advanced formula, which offers a moisture-resistant finish capable of withstanding scuffing, fading, cracking, and peeling. This makes it a good choice for old decks that need a robust protective layer. Additionally, it boasts mildew and mold resistance, which is crucial for outdoor applications where moisture is a concern.

The paint also provides a decent coverage of 200-400 sq. ft. per gallon, depending on the surface texture, and dries relatively quickly, allowing for recoating within 4-6 hours. However, users should be cautious as the painted surface can become slippery when wet, posing a slip hazard. The product is not recommended for areas subject to automotive tires, which might limit its use for certain applications. On the aesthetic side, the low-lustre satin finish gives a subtle shine, enhancing the visual appeal of the deck.

The paint comes with a lifetime limited warranty, showing confidence in its durability. Its easy application process makes it suitable even for those who are not professional painters. Despite its few limitations, such as potential slipperiness and restricted use areas, the KILZ Low-Lustre Enamel Porch & Patio Paint stands out for its durability, moisture resistance, and ease of use, making it a reliable option for rejuvenating old decks.

The Olympic Maximum 1 gal. Redwood Semi-Transparent Exterior Stain and Sealant stands out for its dual functionality as both a stain and sealant, making it a convenient choice for maintaining old decks. Its weather-ready application allows users to clean and stain on the same day, even in temperatures as low as 35°F, and it can withstand rain just 8 hours after application. Additionally, it offers advanced protection against UV rays, moisture, and scuffs, preserving the wood's durability and appearance over time.

This product is suitable for various exterior wood surfaces, including decks, fences, and outdoor furniture, with a semi-transparent finish that accentuates the wood grain and texture while providing a subtle color. It's highly rated for its protective qualities and ease of application, though like many stains, it may require repeated applications over the years to maintain its effectiveness and aesthetic.

With a coverage of up to 400 sq. ft. per gallon, it offers decent spread per application, but this can vary based on wood condition and porosity. This product is a solid option for anyone looking to enhance and protect their outdoor wood surfaces with minimal hassle and effective results.

The Olympic WaterGuard 11.75 oz. Woodland Cedar Semi-Transparent Exterior Wood Stain Plus Sealer is a convenient option for those looking to restore and protect old decks. One of the major strengths of this product is its dual functionality as both a stain and a sealer, making it a time-saver. Additionally, it offers good waterproofing capabilities, essential for protecting wood from moisture damage. Its SUNBLOCK UV defense technology helps guard against sun damage, preserving the wood's appearance over time.

The inclusion of SCUFF GUARD Technology is a bonus, providing additional resistance to scuffs and wear, which is particularly beneficial for high-traffic areas on decks. The semi-transparent finish allows the natural wood grain to show through, giving a pleasant aesthetic while adding a warm woodland cedar hue. This product is also easy to apply, which is a plus for those who prefer to handle their deck maintenance personally.

However, the small size of 11.75 oz. may not be sufficient for larger decks, necessitating multiple purchases. While it offers mildew and mold resistance, its performance in extremely humid or damp conditions might require additional treatments. Additionally, users should be aware that semi-transparent stains might need more frequent reapplication compared to solid stains. This product is best suited for those with smaller to medium-sized decks looking for a blend of aesthetics and protection. It's also ideal for DIY enthusiasts who want a straightforward application process.
