Introduction
In this article, we will discuss the process of finishing a wooden threshold using boiled linseed oil and polyurethane. By following these steps, you can achieve a high durability finish that will protect the wood and give it a smooth, glossy appearance. We will also provide some tips and techniques to ensure a successful outcome. So, let’s get started!
Step 1: Surface Preparation
Before applying any finish, it is important to prepare the surface properly. Start by sanding the wooden threshold using a 220-grit sandpaper. This will help remove any stains and create a smooth surface for the finish to adhere to. Once the surface is sanded, wipe away any sawdust or debris.
Step 2: Using Painting Pyramids
To prevent the wood from touching the surface during the finishing process, use painting pyramids. These are small triangular stands that can be placed under the wooden threshold. They elevate the wood, allowing you to easily apply the finish without worrying about it sticking to the surface.
Step 3: Applying Boiled Linseed Oil
Now it’s time to apply the boiled linseed oil. Pour a small amount of the oil into a container and use a brush to apply it to the entire surface of the wooden threshold. The linseed oil will act as a sealant, protecting the wood and giving it a lustrous appearance. Allow the oil to sit for about 15 minutes before proceeding to the next step.
Step 4: Flipping and Working in the Oil
After the initial coat of linseed oil has been applied, flip the wooden threshold over to ensure that you cover all sides. While working the oil into the wood, remember that gravity will help distribute the oil evenly on the top surface, but you’ll need to put in a little more effort on the sides. Be thorough and make sure to cover all areas of the wood to ensure proper protection.
Step 5: Applying Polyurethane
Once the linseed oil has fully dried, it’s time to apply the polyurethane. Use a brush or a Minwax brush to apply the polyurethane evenly across the surface of the wooden threshold. Countersink any screws holes using a 3D-printed jig and a speed square, ensuring that the screws are flush with the wood. This will provide a seamless finish.
Step 6: Curing and Additional Coats
After coating the wooden threshold with polyurethane, allow it to cure for a couple of weeks. This will ensure that the finish fully sets and hardens, providing maximum durability. Once the initial coat has cured, you can sand it slightly to create a smooth surface, and then apply another coat of polyurethane. This will further enhance the protection and appearance of the wood.
Step 7: Final Touches
After applying the final coat of polyurethane, allow the wooden threshold to cure for another couple of weeks before putting it to use. This extended curing time will ensure that the finish is fully hardened and resistant to wear and tear. Once the full curing process is complete, you can install the wooden threshold securely to the desired location using screws.
Conclusion
By following these steps, you can achieve a high durability finish on a wooden threshold using boiled linseed oil and polyurethane. The linseed oil will protect and enhance the natural beauty of the wood, while the polyurethane will provide a long-lasting, glossy finish. Remember to take your time during each step, allowing for proper drying and curing times. With the right technique and materials, your wooden threshold will be well-protected and aesthetically pleasing for years to come.
