Precautions for the use of water sandpaper

1. The water abrasive paper needs to be polished with water and cannot be dry ground. If it is directly dry ground, the debris of the abrasive will adhere to the gap between the water abrasive paper particles, which will weaken the friction and grinding force of the water abrasive paper. This will not only affect the grinding effect, but also cause the water abrasive paper to be more easily damaged.

2. There are different models of water abrasive paper. When grinding, use coarse abrasive paper with smaller model first, and slowly increase the large model of water abrasive paper to polish and polish again and again.

3. Be patient when polishing, because the same place needs to be polished dozens of times. After each grinding, the model of the water abrasive paper needs to be changed. Before changing, the place just polished must be cleaned with clean water.
