What To Use Seal Outdoor Wood Furniture

Essential Aspects of What to Use to Seal Outdoor Wood Furniture

Maintaining the beauty and longevity of your outdoor wood furniture is crucial, and sealing it properly is an essential step. Choosing the right sealant can make a significant difference in protecting your furniture from harsh weather conditions, insects, and wear and tear. This guide will provide you with all the essential information you need to choose and apply the perfect sealant for your outdoor wood furniture.

Types of Sealants

There are two main types of sealants for outdoor wood furniture: film-forming and penetrating. Film-forming sealants, such as polyurethane or varnish, create a protective layer on the wood's surface, while penetrating sealants, such as linseed oil or tung oil, soak into the wood and seal it from within. Each type has its advantages and disadvantages:

Film-forming sealants provide superior protection against water and dirt but can crack or peel over time, especially if not reapplied regularly.
Penetrating sealants are less visible and more durable, but they offer less protection against water.

Factors to Consider

When choosing a sealant, consider the following factors:

Climate: Harsh weather conditions, such as extreme sun, rain, or cold, require a sealant with higher UV protection and water resistance.
Wood type: Different types of wood absorb and retain sealants differently. Some woods, like teak, are naturally weather-resistant and require less sealing.
Existing finish: If your furniture already has a finish, such as paint or stain, it may affect the compatibility of the sealant.
Maintenance: Some sealants require more frequent reapplication than others. Consider your willingness to maintain the furniture over time.

Application

Proper application is crucial for the effectiveness of the sealant. Here are the general steps:

Clean the furniture: Remove any dirt or debris using a mild soap solution and let it dry completely.
Sand the surface: Lightly sand the furniture to smooth out any rough spots and improve adhesion.
Test the sealant: Apply a small amount of sealant to an inconspicuous area to ensure compatibility and desired finish.
Apply the sealant: Use a brush or roller and apply the sealant evenly in thin coats. Allow each coat to dry completely before applying the next.
Recoat: Most sealants require two or more coats for optimal protection. Follow the manufacturer's instructions for specific recoating times.

Maintenance

To maintain the protection provided by the sealant, it is essential to inspect your furniture regularly for signs of wear or damage. Clean it periodically with a mild soap solution and reapply the sealant as needed. Proper maintenance will extend the lifespan of your outdoor wood furniture and keep it looking its best for years to come.
