Drywall sanders make smoothing patches and drywall joints easier. They are preferred to hand sanding due to their ease of use, overall performance, and productivity. They are practical tools regardless if you are a DIY’er or contractor professional. Drywall sanders may be simple handheld manual models or electric-powered. They may include telescopic pole extensions, built-in vacuums, vac hoses or other attachments and features that make the work easier and more professional-looking with less clean up.

Drywall sanding dust cannot be avoided even when dustless drywall sanders are used. Using the appropriate type of sander helps minimize the escape of the fine drywall dust that coats everything in the area as well as creates possible inhalation issues. It is important to purchase the type (manual or electric), power and speed, and features that best-suit your anticipated DIY or professional need(s).

What You Will Learn From This Guide:

How Do Drywall Sanders Work?

To gain a smooth surface, drywall sanding should only be done on the dry top layer of applied mud. Regardless if you use a lower-powered or dustless sander, there will be floating dust that must be contained as much as possible. Small areas and corners can be sanded using a wet sponge to alleviate dust cleanup. Vacuuming dust as you sand the larger areas also helps reduce the amount of dust that settles into cracks and crevices.

Fill ridges or dents with joint compound before sanding. Fine-grit sandpapers do not speed up the smoothing process. On the other hand, coarse grit sandpaper may leave marks or gouge the surface. Depending on the type of sander you use (manual or electric), 120- to 300-grit sandpapers are recommended for achieving the best results.

Hold a bright light parallel to the wall to check for depressions, marks, or uneven areas after sanding. Circle deficiencies and smooth sand them using a manual sander. Missed pits and deeper dings should be touched-up with joint compound before re-sanding. Before you prime or paint the walls or ceiling, wipe them to remove residual sanding dust.

Advantages

The obvious advantage of using a drywall sander is the smooth result you can achieve faster and with less effort than hand sanding. For contractors and professionals, more powerful, high-speed electric drywall sanders with features and attachments allow even sanding in large and small areas, which increases production and profitability.

Many models are “dustless” and have built-in dust vacuums or some means of connecting to a shop vac to suck the dust from the operation before it is released into the air.

Technologies

Variable speeds allow greater control. Pivoting and telescopic pole heads enable better access to remote and harder to reach areas. Technologies are aiding the ability of drywall sanders to collect dust generated by and during the sanding process. Wet/dry and HEPA wet/dry vacuum technology operate using integrated air-powered orbital sanding turbines that suck dust inside the sanding unit.

What Are The Types of Drywall Sanders?

Manual Sanders

A simple, manually-operated drywall sander is a good, all-purpose complementary tool to a power drywall sander. They are good for making small repairs and small area finishing. They are not recommended for large areas or big jobs because they require more time and effort to attain a smooth surface. The task can quickly become tedious when used to sand large areas. Smoothing seams or patches before painting or doing a single, one-time drywall project may warrant purchasing a less expensive manual sander.

Pole attachments make reaching ceilings and high areas easier. Sanding sponges are also available for sanding corners. A “dustless sander” (a manual sander that connects to a shop vac) is a good choice to minimize drywall dust that readily coats everything within range of your sanding project.

Power Sanders

Power drywall sanders are handheld sanders with large, round, rotating sanding discs. The sanding disc may turn at speeds from 350 rpm to 3000 rpm or more. Overall, they are faster, easier to use, and more efficient, particularly for larger jobs. Dustless models have built-in/integrated vacuums or hoses that suck up most of the excessive dust generated during sanding.

Power drywall sanders with pole-mounted options allow a greater reach. This is particularly beneficial when sanding ceilings or high walls. Pole extensions allow a safe distance between you and the actual sanding operation, which reduces the amount of drywall dust you might potentially inhale. The downside of using the pole attachment is the extra weight it adds and the increased strength required to effectively control and operate it overhead.

What To Look For When Buying A Product?

Certain criteria determine if a manual or electric sander would be your best choice. Will you need specific attachments to make your sanding easier and more efficient?

Before buying a drywall sander:

  • determine the overall size of your project,
  • if you are buying it for home or professional use,
  • if you will be using it for one project or multiple times, and
  • if you will be sanding high walls or ceilings.

Weight

Manual, handheld drywall sanders are lightweight and easily operable. Electric-powered models are heavier due to their motor and attachments that may be designed for professional operations. Power sanders can weigh from 9 to 20 lbs. Aluminum sanders are lighter weight.

The heavier the device is, the more control it requires to achieve the best results. The drywall sander’s weight also impacts how long you can comfortably use it. Although heavy sanders more readily glide over the surface, they require more endurance to effectively operate them overhead for high walls or ceilings and/or for long periods of time.

Pole sanders are lighter but require much more physical pressure against the drywall surface in order to sand the joint compound. Stilts or drywall lifts may be the solution when heavier professional drywall sanders are needed to finish massive ceilings, vaulted ceilings/walls, etc.

RPMs

The greater the RPMs, the faster you should be able to complete your work. However, the mechanism that makes the disc spin faster also tends to increase the sander’s weight. As a result, more control is required to achieve a consistent smoothness. A DIY homeowner that has a single room or wall to sand may do just fine with a lower RPM drywall sander. A contractor, on the other hand, may want a higher RPM sander that is faster and improves overall productivity.

Sanding Discs

Sanding discs come in a variety of grits and sizes. They typically attach to the sanding machine with Velcro. Disc sizes are not standard among drywall sander brands and models. Most drywall sanders include a few sanding discs with purchase, but ensure replacement discs are easily and locally available before you purchase your sander.

Safety and Precautions

Work area preparation prior to sanding is important to minimize and contain the fine, floating, flour-like dust that results during the sanding. Drywall dust floats in the air, finds its way into crevices, and coats everything in the room, including you! Drywall dust is also an irritant that can harm your exposed head and body areas.

  • Remove or cover all surfaces and furnishings with sheets or drop cloths.
  • Seal air-return ducts so the dust cannot spread through the ducts and vents into other areas.
  • Sealing air-return ducts also minimize resultant AC filter blockages.
  • Properly ventilate the area. Open windows and doors.
  • Removing window/door screens that tend to catch the drywall dust eliminates the need to clean them later.
  • Use a box fan to remove dust-contaminated air.
  • Use proper safety gear, including goggles and a dust mask or respirator. Change your dust mask and/or mask filters often. Also, wear coveralls or long pants and a long-sleeved shirt to prevent direct contact of the drywall dust with your skin.

FAQ 

How good are drywall sanders?
They achieve faster, smoother results easier than sanding drywall by hand. Although not all drywall sanding heads effectively get into corners and tight spaces. Check before buying.

What is the best brand on the market?
WEN is a well-known affordable market brand. Porter-Cable is a top-rated professional brand.

What sandpaper is best for drywall?
You do not sand drywall. You sand the joint compound used to fill grooves and cover tape. Coarser 120-grit sandpaper is used for rough-sanding. A final pass with 150-grit sandpaper is optional.

Can you use an electric sander on plaster?
Yes, with fine-grit sandpaper.

How do you vacuum drywall dust?
A wet/dry, HEPA filter, a shop vac is the most effective way to vacuum the dust. Wipe dust-covered items with a damp microfiber cloth.

Pros & Cons of Using

Drywall sanders are fast, efficient, and easy to use. Most DIYers can achieve professional results using long-handled, dustless, variable speed, pivoting-head sanders.

The primary drawback is the dust they inject into the air that needs to be vacuumed later. Even the best “dustless” drywall sanders emit dust. Wear protective clothing and a respirator/mask to prevent direct skin contact and dust inhalation.

Conclusion

Drywall sanders are used to smooth patches and drywall joints faster, easier, and more effectively. They may be simple handheld manual models or heavier, high-speed, electric-powered. Heavier sanders are more durable but can make overhead/ceiling work tedious. Aluminum types are typically lighter weight, but require more pressure to adequately smooth deficiencies.

Technologies: Drywall sanders may be a variable speed which allows greater sanding/pressure control. They may have pivoting heads for greater tight space and corner finishing. Telescopic pole head extensions also provide better overhead and ceiling access. The placement of the motor on the handle can also contribute to better overall balance and sander control. EPA-regulated (ETL-listed) point-of-origin dust containment mechanisms also help ensure the sander provides maximum dust control.

The prices range from very affordable lighter weight sanders that are suitable for DIY or finish sanding to very expensive, high-powered professional units designed for greater performance and productivity.
