Varnishing wood is a traditional technique that, when done properly, results in a stunningly beautiful finish. However, the process can be time-consuming and labor-intensive, which is why many people choose to hire professionals for the job. In this episode, we will explore a new approach to varnishing that combines the use of epoxy and traditional varnish to achieve a professional wood finish for teak.
The Advantages of Using Epoxy and Varnish
Using epoxy as a build-up coat before applying varnish has several advantages. Firstly, with epoxy, you can apply multiple coats in a single day, as long as there is enough time for each coat to cure. This significantly reduces the time required to complete the project. Secondly, epoxy provides a strong base for the varnish, resulting in a finish that is as protective and durable as a traditional varnished job. Lastly, the epoxy used in this technique has UV blockers or inhibitors built into it, which helps preserve the finish and prolong its lifespan.
Step-by-Step Process
Before starting the project, it is essential to gather all the necessary materials. For this project, you will need rubber gloves, acetone, paper towels, a clean mixing cup, mixing sticks, and a disposable brush. The epoxy used is West System’s 105 resin along with their 207 special hardener. This hardener is transparent when cured, ensuring no discoloration occurs when applied to the wood. It also contains UV blockers, making it ideal for use as a base coat under varnish.
Prepping the Teak: Teak naturally contains oils, which can interfere with the adhesion of the varnish. Wipe down the teak with acetone to remove the oils and prepare the wood for the finish.
Mixing the Epoxy: Using a metered pump, mix four pumps of resin with four pumps of hardener to achieve the perfect ratio. Mix in small amounts to prevent wastage.
Applying the First Coat: Apply the epoxy using a brush, ensuring even coverage. For larger areas, rolling the epoxy and then tipping it off with a brush can be a more efficient method.
Curing and Sanding: Allow the epoxy to cure for two to three hours, or as per the manufacturer’s instructions. After it has cured, sand the surface with 80-grit sandpaper to achieve a smooth finish and remove any imperfections.
Applying the Second Coat: Mix a fresh batch of epoxy and apply a second coat. Flood the top surface with a generous amount of epoxy to create a thick base.
Sanding and Prepping for Varnish: Once the second coat has cured, sand the surface with 220-grit sandpaper to prepare it for the varnish. Remove any dust or debris before proceeding.
Starting the Varnishing Process: With the epoxy base prepared, you can now begin the varnishing process using a traditional spar varnish. Apply two to three coats of varnish, allowing each coat to dry between applications.
Conclusion
By using epoxy as a build-up coat prior to varnishing, you can achieve a professional wood finish for teak in a shorter amount of time. The epoxy provides a strong and durable base for the varnish, resulting in a finish that rivals traditional varnished jobs with fewer coats. Additionally, the use of epoxy with UV blockers helps preserve the finish and prolong its lifespan. With this innovative technique, you can enjoy the beauty of varnished wood without the extensive time and effort usually associated with the process.
Remember to always follow safety guidelines when working with chemicals and wear protective gear. With the guidance provided in this article, you can transform your teak surfaces into stunning, long-lasting works of art.
