Introducing the gradient mirror finish coating of Zelkova hardwood.
This time, we requested a countertop surface with a scratch-resistant polyester mirror finish. One of the characteristics of polyester resin is that the coating can be made thick, around 0.3 to 0.5 mm. The coating is harder and less prone to scratches compared to urethane resin, making it suitable for everyday furniture. Additionally, there is minimal shrinkage of the coating due to aging, and the refined, sharp luster lasts a long time, which is the appeal of the polyester mirror finish. Even in the unlikely event that scratches occur, repairs can be made, providing peace of mind.

Detailed information
-
Blue gradient coloring After completing the "green coloring" → "base coat (4 times on one side)" → "sanding," we will apply a blue gradient to the wood base. This is where the craftsman's sense shines. It's a moment of tension!
-
Polyester Clear Topcoat After coloring, a mid-coat (sealer) is applied, and finally, we move on to the topcoat process. Polyester resin is sprayed on generously and evenly. This is repeated four times as "spray" → "interval" → "spray" ... The finish will vary depending on how the intervals are managed, so experience is necessary to determine the timing based on temperature and humidity.

This is a photo of the completed top coat. A clean base was created with the undercoat, and the top coat has been applied evenly, so even before polishing, the ceiling's fluorescent lights reflect well, and the gloss is impeccable.
-
Polishing (Level Sander) After forced drying, we proceed to the polishing stage. The polyester mirror finish is resistant to scratches and has a hard coating, making machine polishing essential. First, we use a level sander with two stages of sandpaper for polishing.
-
Final Grinding (Belt Sander) Next, we will use a belt sander to polish with finer grit paper. Polishing with small machines like hand sanders takes time and can leave rotational scratches, making it difficult to achieve an even finish over a wide area. The mirror finish achieved by skillfully modifying and utilizing large, versatile machines from the piano era is what defines the Piacqua quality.
-
Polishing (Automatic Buffing) This is the "three-head automatic buffing machine" that has been used since the piano era. The painted surface is polished to a glossy finish in an instant. It can polish materials up to a maximum size of w1800×d5000×h150.
-
Gloss finishing (sponge polisher) After using the "three-head automatic buffing machine," polish the finer details with a cotton polisher, and finally, enhance the gloss with a sponge polisher.
-
Final Confirmation Wipe off the compound, check for any cloudiness, and it's complete. Piax has been dedicated to woodworking finishes for 60 years, with a track record of painting over 80 types of wood and a vast accumulation of know-how. Wood has its own characteristics, such as deep vessels, high resin content, and oiliness, depending on the species. While manuals work for artificial materials (like resin and metal), achieving a beautiful finish on "wood" requires painting methods and processes tailored to each species. Additionally, the moisture content of the wood affects the penetration of the paint and the quality of the finish, significantly impacting the durability of the coating. In consideration of our clients' requests, we strive daily to refine our techniques to provide the highest quality finishes, both aesthetically and functionally. Please feel free to contact us for painting consultations or estimates.
