How to Apply Pure Tung Oil to Wood Floors - A Family Tradition and Expert Guide

For many families, applying tung oil to wood floors is a tradition passed down through generations. My grandfather swore by it, and to this day, I still use it for furniture and woodworking projects. However, when it comes to wood floors, tung oil might not be the best choice.

Why Not Use Tung Oil on Wood Floors?

While tung oil is an excellent option for furniture and woodworking, it is not as suitable for wood floors. Tung oil is highly valued for its ability to enhance the natural beauty of wood and provide a durable finish. However, there are some drawbacks to using tung oil on floors:

It can become slippery, especially when wet. It can attract dust and grime. It is not as scratch-resistant as other finishes.

For these reasons, professional wood floor finishers often opt for Varathane polyurethane. Despite the initial cost and complexity of application, it offers lasting protection and a smooth finish that is easy to maintain.

Applying Varathane Polyurethane to Wood Floors

Using Varathane polyurethane on wood floors is a bit more involved than using tung oil, but it is well worth the effort. Here are the steps to follow:

Step 1: Prepare the Wood Floor

Remove any nails or fasteners from the floor. Stabilize the floor, as any gaps or cracks need to be filled. Use wood filler to achieve a smooth surface. Sand the floor lightly to remove any remaining filler and to create a smooth surface.

Step 2: Apply the First Coat

Use a natural bristle brush to apply the first coat. A high-quality brush will help ensure a smooth, even finish. Wear protective gear, such as gloves and a mask, to protect yourself from the fumes and any chemicals. Allow the first coat to fully dry, usually overnight or as specified by the manufacturer.

Step 3: Clean the Brush

After each use, thoroughly clean the brush with lacquer thinner. This is both time-consuming and somewhat expensive. Do not attempt to use water to clean the brush, as water can damage the bristles.

Step 4: Apply the Second Coat

After the first coat has dried completely, apply the second coat using the same brush and technique. Allow the second coat to dry completely, which may take several days, depending on the humidity and temperature in your environment.

Step 5: Curing and Maintenance

Once the second coat is dry, the finish will take some time to fully cure. This can take several weeks. During this time, it is advisable to avoid walking on the floor to prevent scratches and surface damage.

Conclusion: Choose the Best for Your Needs

While tung oil is a fantastic choice for enhancing the beauty and protecting the natural oils of wood, it is not ideal for wood floors. Tung oil can become slippery and is not as durable as polyurethane finishes. However, if you have a particular attachment to using tung oil, it is still a great option for other woodworking projects. For wood floors, investing in varathane polyurethane will provide a longer-lasting, more protective finish that is easier to maintain.

Remember, the choice ultimately depends on your preferences and the durability requirements of your floor. Regardless, both tung oil and polyurethane are time-honored traditions in the world of woodworking.
