Many items in life need to be finely polished to form, such as when polishing leather, wood, metal often use waterproof abrasive paper, then the following introduces the main use of water abrasive paper and precautions you must understand
First, the use of waterproof abrasive paper
1, directly into the water to use grinding
When grinding relatively small items, you can directly put the items in water, and water them while grinding, so that the items will be cleaned each time you mill, and the work efficiency is faster.
2, slowly add water to use
When the items are relatively large, especially when it is inconvenient to put them in water, like furniture, first rough grind with sandpaper with larger particles, and then fine grind with sandpaper dipped in water, and then slowly add water to use
Second, the use of water sandpaper precautions
1, the waterproof abrasive sandpaper needs to be polished with water, can not dry grinding, direct dry grinding will lead to the debris of the sand will be attached to the gap of the water sandpaper sand, resulting in the friction and grinding force of the water sandpaper weakened, not only will affect the effect of grinding, but also lead to water sandpaper more easily damaged, durability becomes low.
2, there are models of abrasive paper, grinding should first use a relatively small model of coarse sandpaper, slowly increase the size of the large abrasive paper, polishing again and again.
3, grinding should be patient, because the same place to grind dozens of back and forth, each time you need to change the model of the sandpaper, before changing must use water to brush the just ground place.

Third, the correct method of waterproof abrasive sandpaper polishing
When sanding with water sandpaper, in addition to paying attention to the correct method of use, but also pay attention to the method of sanding with water sandpaper:
1, wear gloves, grasp the sandpaper by hand, close to the surface of the object to be polished, in the grinding, to be polished along a direction, if it is to polish wood products, also need to be polished along the direction of the wood texture.
2, water sandpaper grinding should pay attention to, a place should not stay too long, so as to avoid the degree of grinding too much, if the grinding effect is not good, you can consider replacing other types of sandpaper.
3, the use of waterproof abrasive sandpaper grinding to focus on grinding the first few times, to hit the flat bottom, the back of the grinding can better play a role, so the front several times of grinding especially pay attention to the correct method.
