Water Sandpaper and Dry Sandpaper, Should Choose Which Kind?

Sandpaper comes in various types, among which the biggest difference is between water sandpaper and dry sandpaper with a coating. So what is the difference between the two types of sandpaper, and how do we choose? Today we're going to give you a rundown.

Water Sandpaper

As the name suggests, water sandpaper, also known as waterproof sandpaper, is a type of abrasive sandpaper that can be used in water. The raw material for water sandpaper is usually silicon carbide, and the paper base is usually made of leather paper. Of course, imported latex paper is also very popular now, especially in developed countries such as Europe and the United States. These latex water sandpapers are more high-end, with the paper base mainly composed of latex paper. The unique feature of this product is that it has excellent flexibility, the sandpaper is more wear-resistant, and when polishing the edges and corners, the sand surface will not be too brittle, making the adhesion of the sand particles stronger. Therefore, the grinding particles are more uniform and the polishing effect is better.

This product is best used with water. Because the gap between the sand grains of water sandpaper is small, and the debris is also small, when used with water, the powder will flow out together with the water, resulting in better results and can be reused. However, Conversely, if the sandpaper is dry, the product debris will adhere to the gaps between the sand grains, causing the sandpaper surface to lose its grinding force and making it less wear-resistant and sharp. Usually, before polishing, the entire sand surface may have already been destroyed, thereby failing to achieve the desired effect. The grit of sandpaper ranges from 80 to 5000. Of course, the larger the quantity, the finer the sandpaper and the smoother the sanding pads will be.

Dry Sanding

Dry sandpaper, also known as coated sandpaper. Compared with water sandpaper, the gap between the sand grains of dry sandpaper is larger. Therefore, when we grind surfaces such as wood, sawdust, or walls, the product debris will fall off automatically, so water is not needed, and dry grinding can achieve better results.

Dry sanding pads generally use high-quality aluminum oxide as the raw material, and the paper base is usually made of latex paper, which has good flexibility and good heat dissipation during use, making it less prone to clogging. Anti-clogging is its biggest feature, making it possible for customers to reuse it during use, and have a long service life. Similarly, the grit of the sandpaper ranges from 80 to 5000. Of course, the larger the quantity, the finer the sandpaper and the smoother the sandpaper pads will be. Dry sandpaper is also widely used, usually for polishing wood, bamboo, metal, or other surfaces. Even in the well-known nail salon industry, dry sandpaper is used for polishing and grinding.
