How to waterproof wood furniture for outdoors?


When it comes to outdoor furniture, wood is a popular choice due to its natural beauty and durability. However, to ensure that your wood furniture can withstand the elements and last for years to come, it is essential to waterproof it. In this article, we will explore different methods and techniques for waterproofing wood furniture for outdoor use.

Choosing the Right Wood

Materials used: The type of wood you choose for your outdoor furniture can greatly impact its ability to withstand moisture and weathering. Some woods, such as teak, cedar, and redwood, are naturally more resistant to water damage due to their natural oils and tannins. These woods are often preferred for outdoor furniture as they require less maintenance and are more resistant to rot and decay.

Sealing the Wood: Before applying any waterproofing products, it is crucial to seal the wood properly. This involves sanding the surface to remove any rough spots and applying a wood sealer or primer. The sealer helps to create a barrier that prevents moisture from penetrating the wood and causing damage.

Waterproofing Techniques

Oil-based Stains: Oil-based stains are a popular choice for waterproofing wood furniture. These stains penetrate the wood fibers, providing a protective layer that repels water. Additionally, they enhance the natural color and beauty of the wood. It is important to choose a stain specifically designed for outdoor use and follow the manufacturer’s instructions for application and maintenance.

Waterproofing Sealants: Waterproofing sealants, such as polyurethane or varnish, can also be used to protect outdoor wood furniture. These products create a clear, protective coating on the surface of the wood, preventing water from seeping in. It is important to choose a sealant that is specifically formulated for outdoor use and provides UV protection to prevent fading and discoloration.

Painting: Painting your outdoor wood furniture can be an effective way to waterproof it. However, it is essential to use a high-quality exterior paint that is specifically designed for outdoor use. Before painting, make sure to clean and sand the surface of the wood to ensure proper adhesion. Multiple coats of paint may be necessary to achieve the desired level of protection.

Maintenance Tips

Regular Cleaning: To maintain the waterproofing of your wood furniture, it is important to clean it regularly. Use a mild soap and water solution to remove dirt and grime, and avoid using harsh chemicals or abrasive cleaners that can damage the protective coating.

Reapplication: Over time, the protective coating on your wood furniture may wear off. To ensure continued waterproofing, it is recommended to reapply the chosen waterproofing product every year or as needed. Follow the manufacturer’s instructions for proper reapplication and maintenance.


Properly waterproofing wood furniture for outdoor use is essential to protect it from moisture and weathering. By choosing the right wood, sealing it properly, and using appropriate waterproofing techniques, you can ensure that your outdoor furniture remains beautiful and functional for years to come.
