Piax has been dedicated to woodworking finishes for 60 years, with a proven 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 can be applied to artificial materials (like resin and metal), achieving a beautiful finish on wood requires painting methods and processes tailored to each species. Additionally, the amount of moisture contained in the wood affects the penetration of the paint and the quality of the finish, significantly impacting the durability of the coating. To provide the highest quality finishes both aesthetically and functionally, we strive to improve our techniques daily, taking into account our clients' requests. Please feel free to contact us for consultations or estimates regarding painting.
Detailed information
-
1) Primer The primer serves the purpose of sealing and stabilizing the substrate, providing a sense of body to the topcoat applied in the next step. Primer paints are more flexible than topcoat paints, allowing them to follow the swelling and contraction of the substrate, and they excel in impact resistance, adhesion, and resistance to film cracking.
-
2) Lower sanding This is an important process that lays the foundation for creating a smooth topcoat, significantly affecting the final finish. It involves sanding with a belt sander, followed by adjustments with a hand sander.
-
Top coating After spraying white enamel, clear paint is sprayed. As this is the final step in the painting process, it determines the finishing appearance in terms of smoothness, gloss, and color.
-
Finally, we are at the polishing stage. The base material this time is a few millimeters thick drywall, which will be used for wall panels. Since it will have a single-sided finish, measures against warping are important. Marking is also essential to ensure there are no areas left unpolished.
-
The belt sander used this time is a machine that has been in operation for over 30 years, originally used for painting pianos. It has been modified to be able to grind up to the size of w1450×d5000×h650.
-
The surface is polished by pressing down on a belt-like paper that is rotating with a pad. It is the craftsman's skill to evenly apply the paper so that no unevenness remains on the surface.
-
We will exchange the coarse paper for fine paper. We will choose the grit of the paper according to the paint and materials. This time, we used two types of paper.
-
Belt sanders can efficiently and uniformly sand a larger area compared to hand sanders. By using large machinery, we achieve high quality and short delivery times.
