How Do You Apply Spar Urethane to Outdoor Furniture?

Applying spar urethane to outdoor furniture is a great way to protect the wood from moisture, sun damage, and other environmental elements. Spar urethane is a special type of oil-based polyurethane that is designed for outdoor use. It dries quickly and provides a long-lasting protective finish.

When applying spar urethane to outdoor furniture, the most important step is to properly prepare the surface of the wood. Start by removing any dirt or debris with a damp cloth or vacuum cleaner before sanding the wood with medium-grit sandpaper. This will help remove any splinters and create a smooth surface for the coat of spar urethane to adhere to.

Once you’ve finished sanding, use a damp cloth or vacuum cleaner again to remove any dust.

Next, apply your coat of spar urethane with a natural bristle brush or foam applicator pad. Start in one corner and brush in even strokes along the grain of the wood until you’ve covered all areas. Be sure to pay extra attention around joints and corners where moisture can settle more easily. Allow each coat of spar urethane to dry completely before adding another layer- usually about two hours per coat depending on conditions like temperature, humidity levels, etc.

Finally, once your last coat has dried completely (usually overnight), give it one final sanding with fine-grit sandpaper and wipe away any dust with a damp cloth before adding one more light layer of spar urethane as a finishing touch.

Conclusion:

Applying spar urethane to outdoor furniture is an easy and effective way to protect it from sun damage, moisture, and other environmental elements while giving it an attractive finish that will last for years. Preparing the surface by removing dirt and debris before sanding, applying even coats of spar urethane with either natural bristle brushes or foam applicator pads, allowing each layer to dry fully before adding another layer, and giving it one final sanding with fine-grit sandpaper are all important steps in applying this protective coating correctly.
