Outdoor wood furniture is a beautiful addition to any patio or backyard, but it can be challenging to protect it from the elements. Natural wood is prone to fading, cracking, and rotting when it is exposed to moisture, heat, and sunlight. One of the best ways to preserve your outdoor wood furniture is to seal it with a protective coating that repels water, resists stains, and prevents UV damage. In this article, we will explore the different types of sealants available, and provide some tips for applying them to your outdoor wood furniture.

Selecting the Right Sealant

When it comes to choosing a sealant for your outdoor wood furniture, there are many factors to consider. Some of the most important things to think about include the type of wood you are working with, the level of protection you need, and the look you want to achieve. Here are some of the most popular sealant options:

Oil-based sealants:

Oil-based sealants are a popular choice for outdoor wood furniture because they penetrate deep into the wood and provide a durable, long-lasting protection. They are available in a range of colors and finishes, from clear to tinted, and can be applied with a brush or sprayer. One of the downsides of oil-based sealants is that they can be flammable and release harmful fumes, so it is important to use them in a well-ventilated area.

Water-based sealants:

Water-based sealants are a safer and more eco-friendly alternative to oil-based sealants. They are typically less flammable and less toxic, but they do not penetrate as deeply into the wood. They are available in a range of finishes, from glossy to matte, and can be applied with a brush or sprayer. Water-based sealants dry faster than oil-based sealants, which can be an advantage if you need to apply multiple coats.


Varnish is a clear, hard-drying finish that provides excellent protection against moisture, UV rays, and abrasion. It is ideal for outdoor wood furniture that will be exposed to harsh weather conditions, such as rain, snow, and extreme temperatures. Varnish is available in a range of gloss levels, from high gloss to satin, and can be applied with a brush or sprayer. One of the downsides of varnish is that it can be difficult to repair if it becomes damaged.

Tips for Applying Sealant

Before you apply sealant to your outdoor wood furniture, it is important to prepare the surface properly. Here are some tips to help you get the best results:

Clean the surface:

Use a mild detergent and water to clean the surface of your wood furniture. Rinse thoroughly, and let it dry completely before applying sealant.

Sand the surface:

Use a fine-grit sandpaper to smooth out any rough spots or splinters on your wood furniture. This will help the sealant adhere better to the surface.

Apply the sealant:

Follow the manufacturer's instructions for applying the sealant. Use a brush or sprayer to apply an even coat, making sure to cover all surfaces of the wood. Let the first coat dry completely before applying a second coat.

Protect the surface:

Once the sealant is dry, protect the surface of your wood furniture from scratches and stains. Use coasters, placemats, and tablecloths to protect the surface from spills and scratches.


Sealing your outdoor wood furniture is an important step in protecting it from the elements. Whether you choose an oil-based sealant, water-based sealant, or varnish, be sure to follow the manufacturer's instructions for the best results. With proper care and maintenance, your outdoor wood furniture will look beautiful for years to come.
