The Allure of a Lustrous Finish
As an experienced woodworker and craftsman, I’ve spent countless hours perfecting the art of wood finishing. Over the years, I’ve experimented with a wide range of products and techniques, always striving to achieve that elusive, professional-grade shine that sets truly exceptional pieces apart. Today, I’m excited to share my insights and tips on mastering wood finishing, so you can elevate your projects to new heights of beauty and durability.
One of the finishes that has become my go-to choice is Waterlox, a tung oil-based sealant that offers unparalleled luster and protection. I first discovered its virtues years ago while working at the Philadelphia Museum of Art, where the furniture conservation department swore by its performance. Since then, I’ve come to rely on Waterlox for the majority of my finishing needs, and I’m here to share why it might be the perfect choice for your woodworking projects as well.
The Versatility of Waterlox
Waterlox’s unique formula combines the deep, vibrant tones of pure tung oil with the quick-drying, durable properties of a lacquer-like finish. This versatility allows you to achieve a wide range of aesthetic effects, from a more natural, satin-like sheen to a glossy, museum-quality look. The beauty of Waterlox is that it can handle just about any type of wood, from delicate maple to rich walnut, without compromising the inherent character of the material.
“Waterlox Original Sealer/Finish has a tung-oil base modified with resins, giving it the luster and vibrancy of pure oil with the quick build and durable protection of a lacquer.”
One of the key advantages of Waterlox is its ability to handle a variety of applications, from furniture and cabinetry to floors and even exterior projects. Regardless of the piece you’re working on, Waterlox can deliver a consistent, high-quality finish that protects against water, stains, and everyday wear and tear.
Mastering the Application Technique
Of course, achieving that flawless, professional-grade finish with Waterlox requires a bit of technique and finesse. Over the years, I’ve developed a method that allows me to maximize the product’s benefits while minimizing any potential drawbacks.
The process starts with thorough surface preparation. I always sand up to 220 grit, ensuring that any scratches or imperfections are smoothed out before I begin applying the finish. It’s also crucial to remove any dust or debris, as even the tiniest speck can disrupt the smooth, even application of the finish.
“Prepping the surface for Waterlox is pretty standard. Sand all of the surfaces to #220 grit, and remove the dust with compressed air.”
Next, I apply my first two coats of Waterlox using a large, round, natural-bristle brush. The key is to get as much of the finish transferred onto the surface as possible, then use the brush to evenly distribute it. After each brushed coat, I go over the piece with a clean, lint-free cotton rag to remove any excess and create a smooth, even sheen.
Once the initial brushed coats have dried, it’s time to level the surface using a medium-grade steel wool. This step helps to create a perfectly smooth foundation for the final padded coats, which are applied using a folded cotton rag. The rag technique allows me to build up a protective, lustrous layer in a series of thin, even applications, minimizing the risk of drips or uneven coverage.
“My padding technique is inspired by French polishing, and lets me build up protection and luster in a series of thin, smooth coats. The process is very forgiving. If you mess up you can just rub the area out, using steel wool for slight mistakes or sandpaper for bigger ones.”
Throughout the process, temperature and air exposure play a crucial role. Waterlox performs best in a warmer shop environment, so I make sure to keep the finishing area heated, especially during the colder months. I also go to great lengths to minimize air exposure, transferring the finish into smaller, airtight containers to prevent it from becoming too thick and unworkable.
Addressing Common Challenges
No finishing process is without its challenges, and Waterlox is no exception. One issue I’ve encountered on particularly oily woods, like koa or rosewood, is that the natural oils can eventually seep out and cause the finish to become gummy and prone to collecting dust and other debris.
In these cases, I’ve found that the only reliable solution is to completely remove the existing finish and start fresh. This typically involves a combination of chemical strippers and sanding, as simply sanding the surface can quickly clog your abrasives.
Another potential pitfall with Waterlox is the tendency for bubbles to form, especially if the application is too thick or the environmental conditions aren’t ideal. To combat this, I’ve found that applying multiple, ultra-thin coats is the best approach, ensuring a smooth, uniform finish without any unsightly bubbles or clumps.
“If an area is still absorbing a lot of finish at this point, feel free to move more finish there with the rag. That said, the next coat should even out the look.”
Despite these minor challenges, the benefits of Waterlox far outweigh the drawbacks. Its deep, lustrous sheen, exceptional durability, and ease of application make it a top choice for woodworkers seeking a professional-grade finish.
Expanding Your Finishing Repertoire
While Waterlox is my personal go-to, I understand that it may not be the perfect fit for every project or personal preference. For those who prefer a more natural look or want to preserve the original color of light-colored woods, I’ve found that a diluted polyurethane can be an excellent alternative.
By cutting the polyurethane with mineral spirits and using the same brush and pad application techniques I employ with Waterlox, you can achieve equally stunning results with a more transparent, color-neutral finish. This approach works especially well for projects where you want to showcase the inherent beauty of the wood without the added warmth or amber tones that Waterlox can sometimes impart.
“If you dilute it half-and-half with mineral spirits, you can use the same brush/pad technique I use for Waterlox to get the same beautiful results, with a similar flexibility of build.”
No matter which finishing product you choose, the key is to approach the process with care, patience, and attention to detail. Proper surface preparation, thoughtful application techniques, and an understanding of how environmental factors can impact the final result are all essential to achieving that coveted, professional-grade shine.
The Final Touch: Buffing and Polishing
Even after applying multiple coats of your chosen finish, the job isn’t quite done. The final step in the process is to buff and polish the surface, ensuring a silky-smooth feel that’s just as pleasing to the touch as it is to the eye.
For this, I turn to a trusty tool that may surprise you – a simple brown paper grocery bag. The paper’s mild abrasive properties gently grab onto any dust particles or imperfections, leaving behind a velvety-soft finish that’s an absolute joy to run your hands across.
“My favorite tool for this is a plain brown paper grocery bag—a mild abrasive that is foolproof and effective. The paper grabs small dust particles that have collected in the final coat, leaving a surface that’s soft and smooth to the touch.”
Of course, if I encounter any significant defects during this final buffing stage, I’ll go back and address them with a bit of steel wool and a reapplication of the finish. It’s all about ensuring that every inch of the surface is consistently flawless, no matter how small the imperfection.
Embracing the Process, Elevating Your Craft
Mastering wood finishing is an ongoing journey, one that requires a keen eye for detail, a willingness to experiment, and a deep appreciation for the art of craftsmanship. As you embark on your own woodworking adventures, I encourage you to approach each project with the same level of care and attention that I’ve developed over the years.
Whether you choose to work with Waterlox, polyurethane, or any other high-quality finishing product, remember that the process is just as important as the final result. Take the time to properly prepare your surfaces, experiment with application techniques, and fine-tune your approach based on the unique demands of each piece.
“The journey from selecting the right can of high-quality spray paint to achieving a professional-looking finish is both art and science. It requires patience, practice, and a keen eye for detail.”
By embracing the nuances of wood finishing, you’ll not only elevate the aesthetic appeal of your creations but also deepen your understanding and appreciation for the craft as a whole. So go forth, explore the world of wood finishes, and let your passion for woodworking shine through in every gleaming, professional-grade surface you create.
