Wet sanding is a popular technique used to smoothen and polish a surface, especially when working with automotive paints and finishes. This technique involves using water or a lubricant to reduce friction and prevent the clogging of the sandpaper. But what grit sandpaper is best for wet sanding? In this article, we'll explore the different grits of sandpaper used for wet sanding and their applications.
What is Wet Sanding?
Wet sanding is a technique used to smoothen and polish a surface by sanding it with water or a lubricant. This technique is commonly used when working with automotive paints and finishes, as it helps to achieve a smoother and more even finish.
What Grit Sandpaper is Best for Wet Sanding?
The grit of sandpaper used for wet sanding depends on the level of roughness or imperfection on the surface being worked on. The lower the grit number, the rougher the sandpaper. As a general rule, the grit of sandpaper used for wet sanding ranges from 400 to 3000.
- 400 to 600 Grit Sandpaper: This is used for heavy-duty sanding tasks such as removing paint and smoothing out rough surfaces. It is not typically used for wet sanding, as it can be too coarse and leave scratches on the surface.
- 800 to 1000 Grit Sandpaper: This grit is used for moderate sanding tasks, such as smoothing out imperfections and removing scratches. It is also commonly used for wet sanding, as it provides a smooth finish without leaving deep scratches.
- 1200 to 1500 Grit Sandpaper: This grit is used for light sanding tasks, such as removing small imperfections and preparing the surface for polishing. It is also commonly used for wet sanding, as it provides a smooth finish and prepares the surface for a final polish.
- 2000 to 3000 Grit Sandpaper: This grit is used for fine sanding tasks, such as polishing and finishing the surface. It is commonly used for wet sanding, as it provides a smooth and reflective finish.

How to Wet Sand
To wet sand, start by filling a container with water or a lubricant such as automotive soap. Soak the sandpaper in the water for several minutes before attaching it to a sanding block or an orbital sander. Apply a thin layer of the lubricant to the surface being worked on, and start sanding with light pressure, making sure to keep the surface wet at all times.
As you sand, periodically rinse the surface with water to remove any debris or residue. As you progress through the different grits of sandpaper, make sure to rinse and dry the surface thoroughly before moving on to the next grit. Finally, polish the surface with a polishing compound to achieve a high-gloss finish.
In conclusion, the grit of sandpaper used for wet sanding depends on the level of roughness or imperfection on the surface being worked on. As a general rule, lower grit numbers are used for heavy-duty sanding tasks, while higher grit numbers are used for fine sanding and polishing. By using the appropriate grit of sandpaper and following the proper wet sanding technique, you can achieve a smooth and polished finish on your work.
