Wooden coasters are a popular choice for adding a touch of elegance to any home decor. Whether you have purchased or handmade your coasters, it is crucial to protect them from potential damage caused by wet drinks. In this article, we will guide you through the process of sealing your wood coasters using a spray-on polyurethane sealant. This clear satin or clear matte sealant not only enhances the appearance of your coasters but also provides a protective layer to ensure their longevity.
Step-by-Step Process: Sealing Your Wood Coasters
Step 1: Choose the Right Weather and Surface
Begin the sealing process by selecting a suitable day with favorable weather conditions. It is recommended to work outdoors in pleasant weather to ensure proper ventilation. Additionally, find a surface that will not be damaged by the sealant. A chunk of scrap wood, cardboard, or a drop cloth are suitable options to lay your coasters on during the sealing process.
Step 2: Prepare for Safety
Before applying the sealant, prioritize safety by wearing protective glasses. This precautionary measure ensures that your eyes are shielded from any potential harm during the sealing process.
Step 3: Shake the Spray Can
Before spraying the polyurethane sealant, it is essential to shake the can thoroughly for a couple of minutes. This step guarantees that the sealant is well-mixed and ready for application. By shaking the can, you eliminate any settling that may have occurred.
Step 4: Spray the Sealant
Hold the can of polyurethane sealant approximately six to eight inches above the coasters. Maintaining a safe distance allows for an even and consistent application of the sealant. Begin spraying, ensuring that a fine layer of sealant is evenly distributed on the surface. Remember, a little goes a long way, so there is no need for heavy spraying during this process.
Step 5: Allow Drying and Assess Quality
After applying the sealant, allow the coasters to dry thoroughly. Polyurethane sealants typically dry within a few hours, depending on the specific product used. Once dry, carefully inspect the coasters to ensure that the sealant layer is smooth, without any streaks or bubbles. If any imperfections are present, use a clean cloth to gently wipe them away. It is crucial to address these imperfections before the sealant sets, as they will be permanent once dry.
Step 6: Optional: Repeat for the Reverse Side
If desired, you may choose to seal the reverse side of your wood coasters as well. Follow the same process outlined above, allowing the sealant to dry completely before flipping the coasters and applying a fine layer to the other side. This additional step ensures maximum protection and longevity for your coasters.
Step 7: Assemble and Enjoy
Once both sides of the coasters are dry and have been carefully inspected for a smooth finish, your project is complete. You can now assemble the coasters as desired and proudly display them in your home. With the protective sealant in place, you can confidently place wet drinks on your coasters without worrying about damaging the wood.
Conclusion
Sealing your wood coasters is a crucial step in ensuring their longevity and protecting them from potential damage caused by moisture. By following the simple steps outlined in this article, you can confidently apply a spray-on polyurethane sealant and achieve a clear satin or clear matte finish on your coasters. Remember to prioritize safety, choose the right weather conditions, and inspect the coasters for imperfections before the sealant dries. With proper sealing, your wood coasters will not only enhance the aesthetic appeal of your space but also provide reliable protection for years to come. So go ahead and seal your coasters, knowing that they are ready to withstand the test of time and serve as a functional and stylish addition to your home decor.
