How to Use Dewalt Drywall Sander? – Guide

The Dewalt drywall sander is designed to make quick work of sanding, shaping, and finishing walls. Here is a detailed guide to using a Dewalt drywall sander.

1. Setting up the Dewalt Drywall Sander

The first step in using a Dewalt drywall sander is to properly set it up. This includes attaching the handle and the dust collection bag, as well as making sure that the sanding disc is properly attached and tightened.

To attach the handle, simply slide it into the designated slot on the sander and tighten the screw.

The dust collection bag attaches to the back of the sander and can be tightened with a drawstring. Make sure the bag is securely attached before you begin sanding.

The sanding disc attaches to the bottom of the sander and is held in place by a knob. Make sure the disc is properly aligned and tightened before using the sander.

2. Choosing the Right Sandpaper and Accessories

One of the most important aspects of using a Dewalt drywall sander is choosing the right sandpaper and accessories.

There are a variety of different sanding discs available, each with a different grit. The grit refers to the coarseness of the sandpaper, with lower numbers being more coarse and higher numbers being finer.

For most applications, medium-grit sandpaper (around 80-120 grit) is ideal. If you’re working on a surface that has a lot of rough texture, you may want to start with a lower grit sandpaper, and then progress to a finer grit for a smoother finish.

In addition to sanding discs, there are also various attachments and accessories available for the Dewalt drywall sander, such as corner sanders and edge sanders.

These attachments can be used to reach tight spaces and edges, making it easier to get a smooth finish.

3. Sanding Techniques

Once you have your Dewalt drywall sander set up and have chosen the right sandpaper and accessories, it’s time to start sanding. The key to getting a smooth finish is to use the right technique.

One of the most important things to keep in mind is to always sand in the direction of the grain. Sanding against the grain can cause the surface to become uneven and can also damage the drywall.

It’s also important to use a light touch when sanding. Pressing too hard can cause the sander to dig into the drywall, leaving deep scratches and uneven surfaces.

Another important technique is to overlap each pass of the sander slightly. This will ensure that you don’t miss any spots and will also help to prevent the sander from digging into the drywall.

4. Dust Collection and Clean-up

One of the biggest challenges of using a drywall sander is the dust it generates. The Dewalt drywall sander comes with a dust collection bag that attaches to the back of the sander.

This bag will help to collect most of the dust, but it’s still important to be prepared for some dust to escape.

To minimize dust, you can use a dust mask and goggles to protect yourself, and also cover any furniture or flooring in the area you are sanding.

After you have finished sanding, it’s important to clean up the area thoroughly. This includes emptying the dust collection bag, wiping down the sander and attachments, and vacuuming or sweeping the area to remove any remaining dust.

It’s also a good idea to let the area sit for a while to allow any remaining dust to settle before doing any painting or other work.

This will help to ensure that the surface is completely clean and free of dust before applying any new finishes.

5. Tips and Tricks

Here are a few tips and tricks to help you get the best results when using a Dewalt drywall sander:

  • Always start with a lower grit sandpaper and progress to a higher grit for a smoother finish.
  • Use a light touch when sanding to prevent the sander from digging into the drywall.
  • Overlap each pass of the sander slightly to ensure that you don’t miss any spots.
  • Keep the dust collection bag emptied and the sander and attachments clean to maintain optimal performance.
  • Allow the area to sit for a while after sanding to let any remaining dust settle before applying any new finishes.


Using a Dewalt drywall sander can be a quick and effective way to smooth out rough surfaces, remove the texture, or prepare a wall for painting.

With the right technique and the right attachments and accessories, you can achieve professional results.

Remember to always protect yourself and the area around you, choose the right sandpaper, and clean the area thoroughly after sanding.
