In this post, we will show you different ways to use wet sanding and how you can remove the haze after the whole process.
What is wet sanding?
Wet sanding is a process whereby an abrasive like sandpaper is used with water or another liquid to give smoothness to a material. The liquid or lubricant (usually water and soap) that is used during this process helps to remove grit particles that remain after dry sanding.
It also helps to prevent clogging which can cause deep scratches. Wet sanding is used during the early stages of buffing and polishing. It is also used during the last stages of sanding when repairing minor surfaces. Lastly, you can also wet sand when removing scratches on the paint.
During the process of dry sanding, some damage might have been done to the underlying material. Wet sanding helps to correct these damages. It is also a good tool that helps in fixing any defects or imperfections during paint correction. These imperfections could be an uneven paint job or the removal of particles and debris that got stuck in the paint.
The process of sanding can create little scratches. The continuous adoption of finer grits of sandpaper helps to reduce the scratches to the barest minimum till the desired result is gotten. During wet sanding, the sandpaper lasts much longer. It does not wear out easily.
The common application of wet sanding.
Wet sanding wood
Over the years, people have adopted the method of dry sanding several wood products to reshape the surface, remove splinters, or make uneven wood straight. Wet sanding can also be used on woodworks in homes e.g. cupboards, chairs, tables, or worktops to give them a glassy and clear appearance
Some wood products like violins, should not be wet sand with a lot of water. Wood gets swollen or wrapped when it absorbs water. The best method is to spray enough water and wipe it off as soon as the sanding is done.
Wet sanding metal
The process of wet sanding a metal gives it a perfect look. Minor defects are removed while improving the shine on the metal. A dull metal that has lost its luster can be revamped after wet sanding properly.
While wet sanding metals, water must be frequently applied to the surface of the metal and also the sandpaper to get a desirable result.
Wet sanding drywall
People use wet sanding for different purposes. It could be to either prepare a room for repairing a little portion or for the process of painting the entire room. Although using wet sandpaper takes a longer time than dry sandpaper, you can see the difference between the two. Sanding with a wet sponge to lubricate the wall helps to remove dust during the process and gives it a better feel after sanding.
There are abrasive sponges that are made for wet sanding but you can use a regular sponge to get your result.
Wet sanding a car
The process of wet sanding a car is commonly used in auto body shops. It helps to repair minor defects and deep scratches on the car. When painting a car, wet sanding helps to remove specks of dust and particles on freshly coated paint.
Other imperfections can also be fixed during wet sanding. A quality detergent, fine grit of sandpaper or sander, and water are best appropriate while sanding a car.
How to wet sand properly
The things you need to wet sand your car properly include
- Lubricant (water and soap)
- Hand scissors
- Sponges and microfiber towels
- Squeegee or pad
- Power buffer
- High-grade car wax

- Soak the sandpaper
Dip the strips of sandpaper in the lubricant and leave it for not less than 5 minutes. also, leave a dry part of the sandpaper so that you can wrap that part around your squeegee
- Wash the area you want to sand
To remove dirt and dust particles, wash the area with soap and water. You can now dry it with microfiber towels.
- Start wet sanding
Fasten onto the squeegee and use the already wet sandpaper to sand the surface gently. Don’t apply too much pressure. You only need to continue to move it mildly in a circular motion.
When there is a lot of bleeding from the paint into the sandpaper, it shows that too much pressure is being applied.
- Continue to lubricate:
The sandpaper you are using must be wet throughout the sanding process. You can soak it over and over just to lubricate it. You can also keep pouring soap and water on the surface you are sanding. This will help to protect the paint from getting damaged
- Treat the surface:
You have to get rid of deep scratches with finer sandpaper such as 1500 and 2000 grit. This will help to remove any imperfection that is left.
- Rinse thoroughly:
After treating the surface, you will rinse it thoroughly. Using a hose with running water will help to remove the soap on the surface.
- Dry the surface:
Now, the car has a clean touch. You can dry it with a wool towel. Do not leave the car directly under the sun. It will cause watermarks to remain on the surface.
