When purchasing sandpaper, you may see sandcloth, which looks similar to sandpaper and is also used for polishing and processing. However, there are certain differences between these two polishing tools, mainly reflected in the following aspects:


1. Different substrates


Abrasive paper is bonded to paper substrate with adhesive, such as Kraft paper, latex paper, waterproof paper, etc; Sandcloth, on the other hand, adheres abrasive to a cloth based substrate.


2. Different usage ranges


Sandcloth is mainly used for rough machining of metal and wood, and is mainly processed into abrasive belts and used in cooperation with abrasive belt machines; Sandpaper is mainly used for medium grinding and fine polishing of metals, woodwork, paint surfaces, and composite materials. It is suitable for various forms such as handheld sheet type, velvet backing adhesive disc sand, and sandpaper tape.


3. Different particle sizes


By comparison, the abrasive particle size of sandpaper is finer, resulting in a more delicate polishing effect; The abrasive particle size of sandcloth is relatively coarse, and the polishing effect is relatively rough. However, the polishing speed and efficiency are fast, but the polishing accuracy is relatively not as high.


4. Different prices


For products of the same specification type, the price of regular sandpaper is usually cheaper than sandcloth, but the price of high-end sandpaper is much more expensive than sandcloth. It is also common to buy sandpaper in Hardware store, and there is relatively less sandpaper.


Actually, sandcloth and sandpaper each have their own advantages:


1. The strength of sandcloth lies in its durability, its resistance to sanding, and its ability to fold back and forth without cracking; The flaw is that the price is relatively higher, it is not easy to buy, and the particle size is relatively large.


2. The advantage of sandpaper lies in its relatively cheap price, wider variety, and finer polishing; The defect is that compared to sanding cloth, it is not as durable and is prone to sanding.


Sandcloth and sandpaper each have their own advantages and disadvantages, and we can choose based on the material of the workpiece and polishing needs. It is usually recommended to use sandcloth for coarse grinding and sandpaper for fine grinding.
