Polyurethane is a popular finish to use on outdoor furniture as it provides excellent durability, water resistance, and UV protection. However, the type of polyurethane you use on your outdoor furniture will ultimately determine the level of protection it receives. In this article, we will explore the different types of polyurethane available for outdoor furniture and determine which is the best option for your specific needs.
Oil-based polyurethane is a popular choice for outdoor furniture because it provides excellent protection against water, sunlight, and other harsh outdoor elements. This type of polyurethane creates a hard, durable finish that is resistant to chips, scratches, and other typical wear and tear. However, oil-based polyurethane takes longer to dry than other types of polyurethane and will require multiple coats to achieve optimal protection. Additionally, oil-based polyurethane has a strong odor and requires proper ventilation when applying.
Water-based polyurethane is another option for outdoor furniture finishing. It dries faster than oil-based polyurethane and has a lower odor. Water-based polyurethane provides excellent protection against water and UV rays, but it is not as durable as oil-based polyurethane. If your furniture will be exposed to harsh weather conditions, heavy use, or constant sunlight, water-based polyurethane may not be the best option.
Alkyd Polyurethane is a combination of oil-based and water-based polyurethane. This type of polyurethane provides excellent protection against water, UV rays, and wear and tear. It dries quickly and has a low odor, making it an excellent option for indoor and outdoor use. Alkyd polyurethane is generally more expensive than other types of polyurethane, but it is worth the investment if you need maximum protection for your outdoor furniture.
When applying polyurethane to your outdoor furniture, you have the option to use a brush or a spray application. Brush application is more time-consuming and requires multiple coats, but it provides optimal protection against water and sunlight. Spray application is faster and more convenient, but it may not provide the same level of protection as brush application. If you are unsure which application method to use, consult with a professional or test both methods on a small area of your furniture before proceeding with the whole project.
In conclusion, the type of polyurethane you use on your outdoor furniture will ultimately determine the level of protection it receives. Oil-based polyurethane provides the most durable and long-lasting protection, while water-based polyurethane has a lower odor and dries faster. Alkyd polyurethane is the best option for maximum protection, but it is the most expensive. When applying polyurethane to your outdoor furniture, you can choose between brush or spray application. No matter what type of polyurethane or application method you choose, be sure to follow the manufacturer's instructions carefully and provide adequate ventilation when applying.
