Yes, you can wet sand with a machine, but it's crucial to do it correctly to avoid damaging the equipment or creating a hazard.
Understanding Wet Sanding with Power Tools
Wet sanding typically involves using water or a lubricant to reduce friction, minimize dust, and achieve a finer finish. While traditionally done by hand, it is possible to use electric sanders for this process.
How to Wet Sand with a Machine According to Experience
Based on practical experience, wet sanding with an electric sander is achievable and safe when done with the right approach. A key insight from someone who has done this for years, including in a floor cleaning business where "EVERYTHING got wet," is the method of applying the liquid.
- Method: Do not dip the sander directly into water or excessive liquid.
- Technique: Use a method like a pump-up sprayer to apply a fine mist or controlled amount of water or lubricant to the surface being sanded. This keeps the material wet without saturating the machine.
- Safety: Concerns about electrocution are dismissed by experienced users who state that those concerns indicate a lack of understanding of how it's properly done (i.e., not submerging the tool).
This method ensures the sander remains functional and the process is effective for achieving a smooth finish with reduced dust compared to dry sanding.
Benefits of Wet Sanding (Generally)
- Reduced dust particles in the air
- Achieves a finer, smoother finish
- Lubricates the surface, extending abrasive life
- Minimizes heat build-up on the surface
Using a machine can significantly speed up these benefits compared to manual wet sanding, provided the correct technique is employed.
