Paint-free board is a kind of wood in interior decoration materials, which has natural texture, clear wood grain, no color difference on the surface, waterproof, moisture-proof and dust-free. Paint-free lines are used to repair the mouth and edge, so that you don't have to worry about making up the ash after nailing, and you don't need to paint, which can save labor and paint costs after construction, avoid unhealthy odor and carcinogens caused by paint, not only save a long-term maintenance cost, but also shorten the construction time. Now the word-of-mouth of the market is better than Fusen plate, right?
