An outdoor furniture is always exposed to the harsh elements of nature and can easily wear and tear over time. This is why it is essential to protect your outdoor furniture from the various weather conditions, including rain, snow, and intense sun rays. One of the best ways to protect outdoor furniture is by using spar urethane. However, the question arises how many coats of spar urethane for outdoor furniture. In this article, we will answer this question in detail and provide you with a comprehensive guide on how to apply spar urethane to your outdoor furniture.
Detailed Discussion on How Many Coats of Spar Urethane for Outdoor Furniture
Before discussing how many coats of spar urethane for outdoor furniture are required, let’s first understand what spar urethane is and why it is used for outdoor furniture.
Spar urethane is an oil-based polyurethane that is specifically designed for outdoor use. Unlike regular polyurethane, spar urethane contains additional UV absorbers, which help to protect against sun damage. It also has a more flexible composition, which allows it to withstand the natural shrinking and expanding of wood due to temperature and humidity changes.
Now, let’s talk about how many coats of spar urethane for outdoor furniture are necessary. A general rule of thumb is to use two to three coats of spar urethane on your outdoor furniture. However, the number of coats you apply depends on various factors, including the type of wood, location, and weather conditions.
Factors to Consider When Deciding How Many Coats of Spar Urethane to Apply
1. Type of Wood: Different types of wood have varying levels of porosity, which affects the number of coats you need to apply. A less porous wood like teak may require only two coats, while a more porous wood like cedar may need three coats or more.
2. Location: The location of your outdoor furniture plays a vital role in determining the number of coats required. If your furniture is situated in a place with intense sun exposure, it could require an additional coat to avoid damage from UV rays.
3. Weather Conditions: If your area experiences harsh weather conditions like heavy rain or snow, you may need to apply an additional coat to ensure maximum protection.
Procedure to Apply Spar Urethane on Outdoor Furniture
1. Prepare the Surface: Ensure that the surface of the furniture is clean and polished before applying spar urethane. Use sandpaper to remove any old coating. Use a brush or vacuum cleaner to remove any dust or debris.
2. Apply the First Coat: Apply the first coat with a brush or a sprayer. Use long, even strokes to spread the urethane evenly across the furniture. Allow the coat to dry for at least 24 hours before applying the second coat.
3. Apply the Second Coat: Apply the second coat using the same technique as the first. Allow the coat to dry for another 24 hours before applying an additional coat if required.
4. Apply Additional Coats: Depending on the factors discussed earlier, you may need to apply additional coats. However, after applying three coats, it may take up to a week or more to cure completely.
Concluding Thoughts on How Many Coats of Spar Urethane for Outdoor Furniture
Spar urethane is an excellent option for protecting your outdoor furniture from harsh weather conditions. Applying two to three coats of spar urethane is generally suitable for most types of wood and most weather conditions. However, if you live in an area with intense weather conditions, applying an additional coat may be necessary. Remember to let the coats dry for at least 24 hours before applying another coat.
