You must know these precautions for water sandpaper
Many items in life need fine grinding to be shaped, such as when grinding leather, wood, and metal, water sandpaper is often used. Then the following introduces the main usage and precautions of water sandpaper that you must know.
1. How to use water sandpaper
1. Use it directly in water
When grinding smaller items, you can directly put the items in the water, and water them while grinding. In this way, the items will be cleaned every time you grind, and the work efficiency is faster.
2. Slowly add water to use
When the grinding object is relatively large, especially when it is inconvenient to put it in water for grinding like furniture, first use sandpaper with larger sandpaper particles to grind it roughly, and then use water sandpaper dipped in water for fine grinding. When the water is gone, slowly add water to use
2. Precautions for using water sandpaper
1. Water sandpaper needs to be polished with water, not dry grinding. Direct dry grinding will cause the debris of the grinding object to adhere to the gap between the sand grains of the water sandpaper, resulting in the weakening of the friction and grinding force of the water sandpaper, which will not only affect the grinding effect, but also make the water sandpaper more easily damaged and less durable.
2. Water sandpaper has different models. When grinding, you should first use coarse sandpaper with a smaller model, and slowly increase the water sandpaper with a larger model to polish and grind again and again.
3. Be patient when grinding, because the same place needs to be polished dozens of times back and forth, and the model of water sandpaper needs to be changed after each grinding. Before changing, be sure to brush the place just polished with clean water.
3. Correct technique for sanding with water sandpaper
When sanding with water sandpaper, in addition to paying attention to the correct method of use, you should also pay attention to the technique of sanding with water sandpaper:
1. Wear gloves, hold the water sandpaper with your hands, and keep it close to the surface of the object to be sanded. When sanding, sand in one direction. If you are sanding wooden products, you also need to sand in the direction of the wood grain.
2. When sanding with water sandpaper, pay attention to not staying in one place for too long to avoid excessive sanding. If the sanding effect is not good, you can consider changing to another type of sandpaper.
3. When sanding with water sandpaper, focus on the first few times of sanding. The base should be smoothed so that the subsequent fine sanding can play a better role. Therefore, the first few times of sanding should pay special attention to the correct technique.
