What to Use to Seal Outdoor Wood Furniture

Outdoor wood furniture adds a touch of natural beauty and warmth to any patio or garden. However, wood is susceptible to the elements, and without proper sealing, it can quickly become damaged and unsightly. Sealing outdoor wood furniture is essential for protecting it from moisture, UV rays, and other environmental factors, extending its lifespan and preserving its appearance. The type of sealer you choose will depend on the type of wood, the desired finish, and the level of protection you need.

Types of Sealers for Outdoor Wood Furniture

There are several different types of sealers available for outdoor wood furniture, each offering unique properties and benefits. Here are a few common options:

1. Oil-Based Sealers

Oil-based sealers, such as teak oil and tung oil, penetrate deep into the wood, providing a natural finish and water resistance. They are often used on hardwoods like teak and mahogany. Oil-based sealers typically require multiple coats for optimal protection and can take several days to dry. While they offer excellent protection, they may darken the wood's natural color.

2. Water-Based Sealers

Water-based sealers are a more environmentally friendly option, emitting fewer volatile organic compounds (VOCs). They are available in both clear and tinted finishes and are often used on softer woods like cedar and pine. Water-based sealers are typically faster drying than oil-based sealers, but they may not offer the same level of moisture resistance.

3. Polyurethane Sealers

Polyurethane sealers create a tough, durable barrier that protects wood from water, UV rays, and scratches. They are available in gloss, semi-gloss, and matte finishes and are suitable for a wide range of woods. Polyurethane sealers are highly durable and water-resistant but can sometimes leave a yellowed appearance over time, especially in direct sunlight.

4. Varnish

Varnish is a type of sealant that provides a clear, protective coating over wood. It is available in different finishes, such as gloss, satin, and semi-gloss, and can be used on both hardwoods and softwoods. Varnish offers excellent protection against moisture and UV rays but requires regular maintenance to prevent cracking and peeling.

Factors to Consider When Choosing a Sealer

When choosing a sealer for outdoor wood furniture, consider these factors:

1. Wood Type

Different wood types have varying levels of natural resistance to moisture and UV rays. Hardwoods like teak and mahogany are naturally more durable than softwoods like cedar and pine. The type of wood will influence the type of sealer you need. For example, teak oil is often used on teak furniture due to its natural oil content.

2. Desired Finish

Think about the desired look and feel of your furniture. Some sealers, like oil-based sealers, create a natural, satin finish, while others, like polyurethane, provide a glossy, durable finish. Choose a sealer that aligns with your aesthetic preferences.

3. Level of Protection

Consider the level of protection required for your furniture. If you live in a humid climate or experience frequent rain, you may need a sealer that offers excellent water resistance. If your furniture is often exposed to direct sunlight, a UV-resistant sealer is recommended. Choose a sealer that meets your specific needs.

4. Application and Maintenance

Some sealers are easier to apply than others. Oil-based sealers require multiple coats and can take longer to dry, while water-based sealers are often faster drying and easier to apply. Consider the level of effort you are willing to invest in application and maintenance. Different sealers also require different maintenance schedules. Some need to be reapplied annually, while others offer longer-lasting protection.

Applying Sealers

Once you've chosen the right sealer, apply it according to the manufacturer's instructions. This typically involves cleaning the wood, sanding it smoothly, and applying the sealer evenly in thin coats. Allow each coat to dry thoroughly before applying the next. It is recommended to apply multiple coats for optimal protection.

With proper sealing, your outdoor wood furniture will remain beautiful and functional for years to come. Regularly inspect the furniture for any signs of wear and tear and reapply the sealer as needed to maintain its protection.
