There are several types of electric sanders available, each with its own advantages and disadvantages. Here’s a brief overview of the most common types:

Type	Description	Best Use
Handheld Sanders	Compact and easy to maneuver, these sanders are great for small areas and corners.	Small rooms, corners, and edges
Detail Sanders	Equipped with a small, flat pad, these sanders are perfect for tight spaces and intricate details.	Small areas, corners, and intricate details
Random Orbit Sanders	These sanders have a random orbit motion that provides a more even sanding surface and reduces the risk of swirl marks.	Large areas, walls, and ceilings
Variable Speed Sanders	These sanders allow you to adjust the speed, making them versatile for various sanding tasks.	Multiple sanding tasks, from light to heavy

When choosing an electric sander, consider the size of the area you’ll be working on, the level of detail required, and your personal preferences.

Preparation

Before you start sanding, it’s essential to prepare the drywall surface. Here’s a step-by-step guide:

Remove any loose or peeling joint compound. Use a putty knife or a drywall scraper to gently remove the loose material.
Fill any holes or cracks with joint compound. Use a putty knife to apply the compound and smooth it out. Allow it to dry completely before sanding.
Sand the drywall with a fine-grit sandpaper (e.g., 120-grit) to remove any rough spots or imperfections. This will help the joint compound adhere better to the surface.
Clean the drywall surface with a damp cloth to remove any dust or debris.

How to Sand Drywall with an Electric Sander

Once your drywall is prepared, follow these steps to sand it with an electric sander:

Attach the appropriate sanding pad to your electric sander. For most sanding tasks, a 5-inch sanding pad is sufficient.
Start sanding in a straight line, following the grain of the drywall. Apply even pressure to avoid creating swirl marks.
Use a random orbit sander for larger areas, as it provides a more even sanding surface and reduces the risk of swirl marks.
For corners and edges, use a detail sander or a handheld sander with a sanding pad attachment.
Change the sandpaper as needed. When the sandpaper becomes clogged with dust, it will lose its effectiveness.
After sanding the entire surface, inspect the drywall for any remaining imperfections. If necessary, sand the area again with a finer-grit sandpaper (e.g., 220-grit) for a smoother finish.
