How to Sand Drywall Without Dust Of 2 Methods

by Michelle Chan 14 Dec 2023 1 comment

When undertaking home improvement projects or renovations, sanding drywall is an essential but often messy and cumbersome task. Are you tired of the traditional sanding methods that leave behind clouds of dust, making the air gritty and settling on every surface? No worry! We have two effective methods that will help you sand drywall without dust: wet sanding and dry sanding by using a drywall vacuum sander. Let's delve into these methods in detail.

how to sand drywall without dust

Method 1. Wet Sanding

Wet sanding is a technique that involves using water to lubricate the sandpaper and prevent dust particles from becoming airborne. Here's how to perform wet sanding on drywall.

wet sanding

  • Step 1. Prepare a drywall sponge. Use plastic drop cloths to protect the room from dust and get yourself a dust mask.
  • Step 2. Submerge the drywall sponge in warm water and let it soak for a few minutes.
  • Step 3. Start sanding the drywall surface using the wet drywall sponge. Keep the sponge and the surface wet by periodically dipping the sponge in the water.
  • Step 4. Work in smooth, even strokes, applying gentle pressure. The water will mix with the drywall dust, forming a slurry that helps prevent dust from spreading.
  • Step 5. Frequently rinse the drywall sponge in water to remove accumulated dust and ensure proper lubrication. Change the water as needed.
  • Step 6. When you finish sanding, wait for the drywall to fully dry.

Wet sanding is indeed for reducing dust while sanding. However, it does have a few drawbacks. It can be very messy due to the water creating a slurry with sanding residue. Wet sanding also requires more physical effort and extends drying time, so it’s great only for smaller projects. If you prefer a superior dust-free drywall sanding method to work with big projects, consider exploring Method 2.

Method 2. Dry Sanding with a Dust-free Drywall Sander

Another more efficient method to sand drywall without dust is by using an electric drywall sander with a vacuum attached, which guarantees dust-free even after completing sanding. These innovative tools are specifically designed to minimize dust while improving sanding efficiency. Let's take a closer look at how to use them.

  • Step 1. Prepare the work area by clearing furniture and covering surfaces with plastic sheets.
  • Step 2. Put on safety gear, including goggles and a dust mask, to protect yourself from any remaining dust particles.
  • Step 3. Choose a sandpaper with right grit. In general, start with a lower-grit sandpaper, such as 100 or 120, to address any high spots, imperfections, or excess joint compound. Then smoothly transition to a high-grit sandpaper like 180, 240 or higher to achieve flawlessly smooth wall surfaces.
  • Step 4. Properly assemble your drywall sander. Ensure that the integrated dust collection bag or vacuum is properly connected and functioning.
  • Step 5. Turn on the electrical drywall vacuum sander and begin sanding the drywall surface.
  • Step 6. Once the sanding is complete, turn off the sander, carefully remove the dust from the dust collection bag, and clean up any remaining dust in the work area.

Tips on Using an Electric Drywall Vacuum Sander:

  • Hold the electric drywall sander firmly and move it in smooth, even strokes across the surface. Avoid applying excessive pressure, as the sander's weight and motion should do the work for you.
  • Work methodically in a circular motion, focusing on one area at a time. Periodically check the progress and adjust the sanding speed or sandpaper grit as needed.
  • Regularly empty or replace the dust collection bag as it fills up.
  • Be careful to prevent the sanding screen from coming into contact with sharp objects or protrusions such as screws and nails, as they have the potential to damage the pad.
