Wood furniture is a popular choice for outdoor settings. However, due to exposure to various weather elements, outdoor wood furniture is susceptible to damage. One effective way to protect it is by using a wood sealer. This article will discuss the different types of wood sealers, and which one is best suited for outdoor wood furniture.

Types of Wood Sealers

Wood sealers come in different formulas and types. To determine which type is best, it is important to consider the following:

  • Type of wood
  • Climate or weather conditions
  • Desired finish

The most common types of wood sealers are:

  • Oil-based sealers
  • Water-based sealers
  • Lacquers and varnishes
  • Sealing oils

Lacquers and Varnishes

Lacquers and varnishes create a protective film over the wood surface. They are durable and resistant to wear and tear. However, they are not recommended for outdoor furniture, as they tend to crack or yellow when exposed to UV rays. Moreover, they require frequent maintenance.

Oil-based Sealers

Oil-based sealers are a popular choice for outdoor wood furniture. They offer good protection against water damage, UV rays, and fungi growth. They are also easy to apply and provide a natural look to the wood. However, they take longer to dry, and may emit a strong odor. They are also flammable and require careful handling.

Water-based Sealers

Water-based sealers are another option for outdoor wood furniture. They are eco-friendly, low in VOCs, and have a quick drying time. They provide good protection against water damage, but are not as effective against UV rays. They are available in a variety of finishes, from clear to tinted. However, they tend to raise the wood grain, requiring the wood to be sanded before application.

Sealing Oils

Sealing oils, such as teak oil or tung oil, are also commonly used for outdoor wood furniture. They penetrate the wood fibers, providing good protection against water and UV rays. They also enhance the natural color and texture of the wood. However, they require frequent reapplication, and may attract dirt and dust.


Choosing the right wood sealer for outdoor furniture is crucial to its protection and longevity. Oil-based sealers are a good choice for their water resistance and durability, while water-based sealers are eco-friendly and have a quick drying time. Sealing oils provide a natural look and enhance the wood grain. Regardless of the sealer chosen, it is important to follow the manufacturer's instructions and maintain the furniture regularly.
