Sandpaper is an essential tool in any drywall finishing project. It is used to smooth out rough spots and imperfections in the drywall mud, resulting in a smooth and polished finish.
However, with so many types of sandpaper available, it can be confusing to choose the right one for the job.
What Sandpaper for Drywall Mud?
Drywall mud is a mixture of water and sand used to repair drywall. You can use regular sandpaper to sand the mud, but you’ll need to be careful not to scratch the drywall. Instead, use a sanding sponge or a sanding block to avoid scratching the drywall.
In this article, we’ll discuss the different types of sandpaper and what sandpaper is best for drywall mud.

What Sandpaper for Drywall Mud? – Guide
Sandpaper is an abrasive used to remove sanding scratches from drywall mud. Here is the guide about sandpaper for drywall mud:
Understanding Sandpaper Grits
Sandpaper is graded by its grit, which refers to the size of the abrasive particles on the paper. The higher the grit number, the finer the particles and the smoother the finish.
For drywall mud, it is recommended to start with a coarse grit and gradually work your way up to a finer grit.
Coarse grit sandpaper (60-100 grit) is ideal for removing excess drywall mud and roughing up the surface for further sanding.
Medium-grit sandpaper (120-150 grit) is used to smooth out the surface and remove any scratches left by the coarse grit.
Finally, fine-grit sandpaper (220-240 grit) is used to achieve a smooth and polished finish.
Types of Sandpaper
There are two main types of sandpaper: open-coat and closed-coat. Open-coat sandpaper has fewer abrasive particles per square inch, allowing it to cut more quickly and prevent clogging.
This type of sandpaper is ideal for rough sanding and removing material quickly. Closed-coat sandpaper, on the other hand, has more abrasive particles per square inch, resulting in a smoother and finer finish. It is best used for finishing and polishing.

Sandpaper Backing Material
The backing material of sandpaper is just as important as the grit and type of sandpaper.
Sandpaper can come in various backing materials such as paper, cloth, or film. The backing material affects the durability, flexibility, and ease of use of sandpaper.
Paper-backed sandpaper is the most common and affordable type of sandpaper. It is suitable for light to medium sanding tasks but tends to tear easily when used on rough surfaces.
Cloth-backed sandpaper, on the other hand, is more durable and flexible, making it ideal for heavy-duty sanding tasks.
Film-backed sandpaper is the most durable and flexible of the three types, making it ideal for wet sanding and finishing.
Sandpaper for Drywall Mud
When it comes to sanding drywall mud, it is recommended to use sandpaper with a grit of 120-150.
This grit will effectively smooth out the surface without removing too much of the drywall mud.
Coarse grit sandpaper (60-100 grit) should only be used for rough sanding and removing excess drywall mud. Fine grit sandpaper (220-240 grit) should only be used for the final finishing touches.
Open-coat sandpaper is ideal for sanding drywall mud as it cuts quickly and prevents clogging.
However, it may leave behind scratch marks that require further sanding with closed-coat sandpaper. Closed-coat sandpaper is ideal for finishing and polishing drywall mud.
Paper-backed sandpaper is suitable for light to medium sanding tasks, while cloth-backed sandpaper is more durable and flexible, making it ideal for heavy-duty sanding tasks.
Film-backed sandpaper is the most durable and flexible of the three types and is ideal for wet sanding and finishing.
Sanding Tips for Drywall Mud
Sanding drywall mud can be a messy and time-consuming task, but with these tips, you can achieve a smooth and polished finish quickly and easily.
Firstly, make sure the drywall mud is completely dry before sanding. Sanding wet or damp drywall mud can result in clumps and uneven sanding.
It’s recommended to wait at least 24 hours before sanding to ensure the drywall mud is completely dry.
Next, use a sanding block or pole sander to sand the drywall mud. This will help ensure a more even sanding surface and prevent uneven sanding.
Use long, even strokes, and avoid applying too much pressure, as this can result in uneven sanding and even damage to the drywall.
As you sand, periodically check your progress by wiping the surface with a dry cloth. This will help you identify any areas that require further sanding and prevent over-sanding.
If you notice any rough spots or imperfections, use coarser grit sandpaper to smooth them out before continuing with finer grit sandpaper.
Finally, when you’ve finished sanding, make sure to clean up any dust and debris left behind.
Use a vacuum or damp cloth to remove any dust from the surface, and sweep or vacuum the surrounding area to prevent the dust from spreading.
what grit sandpaper for drywall mud?
When sanding drywall mud, the grit of sandpaper you choose depends on the stage of the sanding process.
For initial sanding to remove high spots, rough patches, or excess mud, you will need a coarse-grit sandpaper, such as 80 or 100 grit.
This grit helps to level the surface effectively. Once the surface is relatively smooth, you can switch to a finer-grit sandpaper, such as 120 or 150 grit, for further smoothing and feathering the edges.
Finally, for the finishing touches and achieving a smooth, polished surface, you can use an even finer grit sandpaper, such as 220 grit or higher.
Conclusion
When it comes to sanding drywall mud, the type of sandpaper you use is critical to achieving a smooth and professional finish.
Different grits of sandpaper will provide different levels of smoothness, so it is important to select the right kind for the job.
With the right knowledge and the right materials, you can create a beautiful and professional result that will last for years.
Whether you are a DIY enthusiast or a professional contractor, make sure to use the right sandpaper for drywall mud and make your walls shine!
