Using 360 grit sandpaper will make it smoother. If there is no high requirement for smoothness, 280 grit sandpaper can be used. Wood polishing and the selection of paint are also closely related, and the quality of polishing directly affects its beauty.


Correct technique for sandpaper polishing


Water sandpaper, also known as water sandpaper, as the name suggests, is a type of sandpaper that can be polished in water. When using water sandpaper for polishing, it can be dipped in an appropriate amount of water before polishing, or it can be directly immersed in water or washed with flowing water for polishing. Water sandpaper needs to be used together with water. If it is directly dry ground, the debris of the polishing material will adhere to the gaps between the sand particles of the water sandpaper, causing the friction and grinding force of the water sandpaper to weaken, and the application effect will naturally be greatly reduced.


Which is finer, 800 sandpaper or 2000 sandpaper?


The difference between 2000 sandpaper and 800 sandpaper is that the larger the number, the more sand particles there are, and the finer the sand particles, which is where the difference lies between fine sandpaper and coarse sandpaper.


The 800 grit sandpaper is very thick, and the 2000 grit ground paint surface is finer and brighter after polishing, but the 2000 grit sandpaper is very expensive.


1. First, use 800 grit sandpaper to polish the scratches, and flush the paint and damaged parts while polishing to roughly smooth them.


2. After polishing with 800 grit sandpaper, there will be some fine marks, so it is necessary to continue polishing with 2000 grit sandpaper. Pay attention to flushing and polishing until smooth.


What types of sandpaper are there?


1. Sponge sandpaper


Sponge sandpaper is a common type of sandpaper that is suitable for polishing the oily parts of various materials and items, and is often used for surface polishing of furniture products.


2. Dry sanded paper


Dry sanding paper has a wide range of fineness options, suitable for polishing metal surfaces, wood surfaces, putty, and coatings. It is also widely used in wood processing, stone processing, and even precision mold polishing. This type of sandpaper has many advantages, such as anti clogging, anti-static, good softness, high wear resistance, and so on.


3. Water frosted paper


The terrazzo paper generally needs to be used in cooperation with water. It can be dipped in water, soaked in water and flowing water. The sand is usually made of silicon carbide, and the gap between the sand particles is small. Since the debris will flow out with the water during polishing, its durability will be awesome than that of dry terrazzo paper. Water sandpaper has a wide range of applications, including stone polishing, hardware processing, mold processing, wall atomic ash polishing, and other fields.


When using sandpaper, it is important to avoid direct dry grinding, as this may result in debris being left in the gaps between the sand particles, thereby affecting the polishing effect.
