A Beginner’s Guide to Sanding with an Electric Sander: Smoothing Out Drywall

Sanding drywall can take a long time and require a lot of labor, especially if done by hand. Yet, you can easily obtain a smooth and polished finish with the correct equipment and methods. An electric sander is one of the best tools for drywall sanding. This article will cover all you need to know about using an electric sander to sand drywall, from comprehending the procedure to perfecting the approaches.

Knowledge of Drywall Sanding

Understanding the need for drywall sanding is crucial before delving into the mechanics of electric sanding. Sanding aids in providing a homogeneous surface for painting or wallpapering by removing any drywall defects or inconsistencies. There are two different types of sanders available for drywall sanding:

  1. Manual sanders and
  2. Electric sanders.

Electric sanders have many benefits, including speed, efficiency, and convenience of use, whereas manual sanders need more time and effort.

Getting Ready for Sanding

You must acquire the required tools and equipment before starting the sanding procedure. This comprises sandpaper, an electric sander, a vacuum, and safety equipment including goggles and a dust mask. In order to stop dust from spreading, you should also cover any furniture or floors with drop cloths and seal off any vents or openings. Next, you’ll need to cover your eyes and face with safety goggles and a dust mask to protect yourself from dust and debris.

How to use an electric sander to sand drywall: Steps

Using an electric sander can make drywall sanding simpler and more effective. Sanding drywall can be a tiresome and time-consuming task. Below are the procedures for using an electric sander to sand drywall:

Step 1: Choose the right type of electric sander – The best kind of electric sander to use is a random orbital sander or a finishing sander with a rectangular pad made especially for drywall sanding.

Step 2: Set up the workspace – To shield it from dust and debris, cover the surrounding area with plastic sheeting or drop cloths.

Step 3: Use the proper protective equipment – To safeguard oneself from dust and loud noise, put on safety glasses, a dust mask, and hearing protection.

Step 4: Begin by using low-grit sandpaper – To remove any lumps or rough places on the drywall, start with low-grit sandpaper, such as 80 or 120.

Step 5: Sand in a circular motion – Move the electric sander across the drywall in a circular motion while using light pressure and a steady pattern.

Step 6: Increase the grit gradually – Go to higher grit sandpaper, such as 220 or 320, once the initial rough patches have been eliminated for a smoother finish.

Step 7: Maintain a spotless sanding surface – To increase the effectiveness of the electric sander, use a sanding screen or vacuum to remove dust and debris from the sanding surface.

Step 8: Check for smoothness – After sanding, run your fingers over the drywall to feel for any smooth places or defects that could still be there.

Step 9: Check for smoothness – Remove the plastic sheeting or drop cloths from the work area and sweep up any dust and debris using a vacuum or dustpan.

Electric sander techniques for sanding drywall

The right technique is essential when using an electric sander to sand drywall. Start by connecting the sandpaper to the sander, being careful to select the right grit for the project at hand. Apply even pressure to the drywall by smoothly and fluidly moving the sander back and forth. Avoid using too much force or leaving the sander in one place for too long to prevent uneven sanding or drywall damage. Keep the sander moving continuously while you sand to avoid a buildup of dust and debris.

While drywall can be efficiently and effectively sanded using electric sanding, there are certain typical errors to avoid. For instance, using a sander with an excessively high grit might cause excessive dust and damage to the surface of the drywall, while using one with an excessively low grain can leave behind deep scratches that are challenging to remove. Moreover, poor cleaning and maintenance can shorten the lifespan and diminish the effectiveness of your electric sander.

There are a few more things to keep in mind while using an electric sander to sand drywall in order to have a flawless finish. You can get a more equal finish, for instance, by starting with a low grit and gradually moving up to a higher grit. The amount of dust created during the sanding process can also be decreased by using a sanding screen rather than sandpaper.

Tidying up

It’s crucial to thoroughly clean the work area after sanding to stop dust and debris from spreading. Start by clearing away any extra dust and debris from the area with a vacuum cleaner or dustpan. To stop it from spreading to other areas of your house or business, you should also dispose of any debris and dust in a sealed bag. Finally, to guarantee that your electric sander works effectively for upcoming projects, make sure to regularly clean and maintain it.


Can I sand drywall with any electric sander?

A random orbital sander or a finishing sander with a rectangular pad specifically made for sanding drywall is recommended instead of using any electric sander, even if this is technically possible.

What grit sandpaper should I use when using an electric sander to sand drywall?

For a smoother finish, it is advised to start with a lower grain of sandpaper, such as 80 or 120, then gradually work your way up to a higher grit, such as 220 or 320.

How can I stop dust and other debris from circulating when sanding?

You may lessen the amount of dust produced by switching to a sanding screen instead of sandpaper, and you can stop it from spreading by removing extra dust and debris with a vacuum or dustpan.

Can I use a wet sanding method on drywall with an electric sander?

Drywall should not be wet sanded since doing so risks damaging the paper surface and making the joint compound mushy and challenging to work with.

How do I maintain and clean my electric sander after drywall sanding?

After each use, your electric sander needs to be thoroughly cleaned and maintained. This includes emptying the dust-collecting bag, cleaning the sander with a moist cloth, and applying oil or grease to the moving parts.

Can using an electric sander to sand drywall be dangerous?

Using an electric sander carries inherent risks, just like using any power equipment. To lessen the chance of getting hurt or inhaling harmful dust and debris, it’s crucial to adhere to all safety precautions and wear the proper protective gear, such as safety glasses and a dust mask.
