Sandpaper is widely used in the polishing process of wooden products, making their appearance smoother. Today, I will introduce to you what kind of sandpaper should be used to polish wooden products.


1. Iron sand paper. Iron sandpaper is a common dry sanding paper commonly used for polishing metal surfaces, but it can also be used for polishing wood, but it is generally used for rough grinding.


2. Water sandpaper. Water sandpaper can also be used to polish wood, but due to the need to polish with water, it has a significant impact on the wood and is generally less used.


3. Wood sandpaper. As the name suggests, wood sandpaper is specifically used to polish wood, and different models of wood sandpaper are used for polishing according to different polishing requirements.


There are several common types and application processes of wood sandpaper:


1. In the white stubble state, 80 # sandpaper is generally used for polishing to remove scars, wood wool, and dirt from the white billet.


2. After completing the preliminary polishing, 360 # sandpaper is generally used for edge trimming and burring. Using the technique of flat grinding, sandpaper is often used to wrap hard rubber or small wooden blocks for large surface polishing.


3. After painting the wooden products, use 360 # sandpaper to fully grind the primer, and then use 600 # sandpaper to treat the sand marks.


4. The final polishing can be fully polished with 1000-1500 # sandpaper, polished to a bright finish, and then subjected to the final spray painting treatment.


The above is an introduction to the commonly used sandpaper for polishing wooden products and the usage methods of different types of sandpaper. I hope it can be helpful to everyone.
