The Gorilla All Purpose Wood Filler, 16 Ounce Tub, is a versatile product ideal for repairing cracks, gouges, and holes in wood. It’s designed for both indoor and outdoor use, making it suitable for deck repairs. A major strength of this wood filler is its easy application; it spreads smoothly, allowing for a natural finish. This feature is particularly beneficial for those who may not have much experience with DIY wood repairs.

Additionally, the filler is water-resistant, which is crucial for outdoor use, like on a deck, where it will be exposed to the elements. Another advantage is its shrink and crack resistance, ensuring the repairs remain intact over time. The product also boasts high performance in terms of stainability and paintability, allowing you to match the color to your deck seamlessly.

Its sandability means you can achieve a professional-looking finish, blending the repair with the rest of the wood seamlessly. Gorilla All Purpose Wood Filler is a strong candidate for deck repairs, providing ease of use, water resistance, and a good finish.

Goodfilla Neutral Base is a high-quality, water-based wood filler specially designed for both professional woodworkers and DIY enthusiasts. Its liquid form makes it easy to apply and sand, which can save you time during your deck repairs or other woodworking projects. The filler doesn’t shrink, sink, or crack, which means you usually only need one application to achieve a smooth surface.

It has excellent adhesion and can be tinted or stained in any color, giving you flexibility when matching wood tones on your deck. Another plus is its durability: it remains flexible enough to handle wood movement and has a long shelf life because it can be rehydrated with water, making it a practical choice for occasional users. The product is also eco-friendly, non-toxic, and made in the USA.

Since it comes in a gallon size, it could be more than you need for small repairs, but it offers good coverage for larger projects.
