Sandpaper for Drywall
Take a moment to look around your room. It’s challenging to find an interior space, whether commercial or residential, that hasn’t been touched by drywall. Gypsum board is a cost-effective and practical solution for finishing interior walls and ceilings, and it’s ubiquitous.
We all understand that hanging and taping drywall is a demanding task. Those who have experience in this field know the hard work, attention to detail, and physical effort it demands. However, drywall sanding is an equally crucial step that often doesn’t receive the attention it deserves, despite its importance.
Proper Sandpaper, and the Best Drywall Sanding Tools
Obtaining perfectly smooth walls that are ready for paint is unattainable without the right sanding technique. To achieve this, you’ll need the correct sandpaper for the job, as well as the best tools and equipment available. By considering these factors, your drywall project can be successful.
Now, let’s delve into the realm of appropriate sandpaper for drywall and explore the best tools for drywall sanding.
What is the Top Sandpaper Grit for Drywall?
To determine the ideal sandpaper grit for drywall, it’s essential to grasp the fundamentals of how sandpaper grit functions. Sandpaper grit ranges from 40-grit to 400-grit, with higher numbers signifying finer grits. For drywall work, a medium-fine sandpaper in the 100-150 grit range is generally recommended. However, your choice may depend on the type of drywall joint compound you’ve applied, so it’s wise to consult the manufacturer’s recommendations.
Fine-Grit, Medium-Grit, Heavy-Grit Sandpaper
Sandpaper with a grit of 220 or above is ineffective for sanding drywall, as it produces abrasions too fine to be noticeable. Coarse-grit paper like 80-grit is unnecessary, as modern drywall joint compounds are soft enough to be sanded down to 180-grit. Using sandpaper coarser than 100-grit might leave visible scratches in the drywall mud and could even damage the drywall paper beneath the mud. When using an orbital sander, opting for a finer 150-grit paper can yield better results.
What Tools Should I Use to Sand Drywall?
Now, let’s dive into the enjoyable part: the best drywall sanding tools. The quality of your drywall project can hinge on your choice of tools. Without the right tools, you risk wasting time, money, and potentially damaging the drywall and joint compound. The selection of drywall sanding tools should align with the scale of your project. For simple patches, a sanding block may suffice.

Where to Buy the BraveX Electric Drywall Sander
Drywall Sandpaper Basics If you’re embarking on your first drywall sanding project, it’s essential to understand the basics to ensure your project starts off on the right foot. Sandpaper is the abrasive material used to sand drywall mud for a smooth finish. To utilize sandpaper effectively, you’ll need a sanding device, either a hand-sander to which you can attach pre-cut sandpaper screens or an electric sander, as discussed earlier.
Power Sanders or Hand Sanders
Power sanders, including orbital and circular electric sanders, are incredibly efficient, making them ideal for more extensive drywall projects. When sanding drywall, especially larger areas, it’s highly advisable to wear protective gear, even when working on small sections.
Safety First
Protective goggles will safeguard your eyes from drywall dust, while a dust mask will prevent you from inhaling excessive dust, which can accumulate in the room. When sanding drywall, using plastic sheeting to cover furniture, electrical boxes, outlets, and any items you want to keep dust-free is a wise precaution.
What is the Top Grit Sandpaper for Drywall?
For sanding drywall in preparation for painting, sandpaper in the 120 to 150 grit range is highly effective. Even sandpaper with a grit as high as 220 can be suitable for sanding dried drywall joint compound. Sandpaper with a grit under 100 should be avoided on drywall mud, as it may damage the finely applied joint compound, resulting in streaks, lines, and divots. While shopping for sandpaper, you might come across garnet paper, silicon carbide, and aluminum oxide. For drywall sanding, it’s recommended to choose a less coarse grit paper like garnet or aluminum oxide over silicon carbide.
Less Coarse Sandpaper for Drywall
Silicon carbide sandpaper, often black in color, features a closed coat and a hard edge, making it ideal for sanding harder surfaces like metal or wood finishes. However, due to drywall’s paper-based nature and the substantial dust generated by modern lightweight joint compound, open types of sandpaper that clog less are preferable. While both garnet paper and aluminum oxide work well, if you must choose between the two, aluminum oxide is the more cost-effective and durable option.
Tips for Sanding Drywall
Once your drywall is hung, and the joints, seams, corners, and gaps are taped, it’s crucial to let the joint compound dry thoroughly before sanding. Sanding is the final step standing between you and beautifully painted walls and ceilings. Therefore, it’s paramount to take your time and employ the right techniques to achieve a smooth finish, whether you’re patching a small hole or working on a larger project.
My Top 5 Drywall Sanding Tips
- Before commencing any sanding, inspect the drywall, looking for exposed screws, cracks, and imperfections. Address any taping errors before you begin sanding.
- Utilize a dust-free sander with a vacuum suction system to minimize dust and simplify cleanup.
- Choose your sandpaper grit based on the type of joint compound, following the manufacturer’s recommendations.
- Always wear eye protection and a dust mask, and ensure proper ventilation to avoid inhaling significant amounts of drywall dust.
- Exercise restraint when sanding. Start with a light touch, as you can always sand more if needed. Over-sanding may necessitate applying more drywall mud, which can be time-consuming.
Wet Sanding Drywall vs. Dry Sanding
Up to this point, we’ve focused on dry sanding, which involves attaching a sanding screen to a hand drywall sander or sanding pole to smooth your drywall. This method is named “dry” because it generates a considerable amount of dust and doesn’t involve water. The majority of your drywall work can be dry sanded.
However, there’s an alternative technique called wet sanding, which is accomplished using a sanding sponge.
The Drywall Sanding Sponge
Sanding sponges are available in various grit sizes, similar to sandpaper. For finishing drywall, a medium-grit sponge is typically recommended. Sanding sponges offer several advantages, as they are cost-effective, durable, and can be used alone or in conjunction with fine sandpaper.
Wet sanding is particularly useful for sanding small patches of drywall or working on drywall corners, as hand sanding in corners can be challenging. Sanding sponges easily fit into corners and are user-friendly.
Wet Sanding for Small Repair Jobs
With small, circular motions, you can achieve a smooth finish comparable to what a hand sander can produce. Another benefit of wet sanding is its cleanliness compared to dry sanding, which generates a substantial amount of dust. The water in the wet sanding sponge absorbs the dust, simplifying cleanup, and reducing the need for extensive vacuuming after the project.
Large Sanding Projects
For drywall sanding projects that extend beyond small repairs or single walls, additional equipment may be necessary. An orbital power sander can make sanding multiple drywall surfaces a breeze, with many models equipped with a vacuum system to minimize dust generation. The preferred electric power drywall sander, mentioned earlier, is an excellent option for large projects, making the investment worthwhile. Additionally, if you have high ceilings, a drywall pole sander may be required to reach and extend all the way to the ceiling.
Hand Sanding Vs Power Sanding
Power sanding is a great choice for extensive projects, as it can significantly reduce the time required. However, caution is essential. In the wrong hands, a power sander can quickly ruin a well-executed taping job. Using a power sander with an overly coarse grit or excessive speed can lead to dips, gouges, and damage to your meticulously taped walls. If you opt for a power sander, it’s advisable to start with the lowest power setting and exercise vigilance to avoid removing too much joint compound.
Gouges and Problem Areas
While sanding, if you encounter deep gouges or depressions in the gypsum board, place a lamp parallel to the wall to illuminate these problematic areas more effectively. Mark these areas and fill them with joint compound. It’s unwise to attempt to sand out gouges or pits; it’s easier to refill them, wait for the mud to dry, and then sand these smaller areas using a circular motion.
What Type of Sandpaper Lasts the Longest?
Understanding the various types of sandpaper is crucial to selecting the right product for your project. There are six different sandpaper types to consider:
- Garnet: Ideal for hand-sanding and effective at prepping wood for minor scratches and dings. However, small grit-size garnet particles wear out quickly as they break during sanding.
- Emery: Used in power sanding tools and hand sanding, it’s commonly employed to remove paint or rust when refinishing metal. Emery cloth sandpaper is available for curved or delicate surfaces.
- Aluminum Oxide: A versatile option suitable for drywall, wood, metal, and plastic. It typically lasts a long time, making it a wise choice for power sanding.
- Silicon Carbide: Removes material faster than aluminum oxide but has a shorter lifespan. It is often used on drywall joints and can be employed for wet sanding due to its waterproof backing. It’s particularly useful for hardened and rough drywall compound.
- Zirconia Alumina: Best for metal, fiberglass, and wood surfaces, commonly found in disc sanders and belt sanders. It outlasts aluminum oxide.
- Ceramic Alumina: Long-lasting and ideal for disc and belt sanders. It delivers an aggressive finish suitable for tough tasks that lighter grits can’t handle.
Drywall Sanding Advice – The Top Sandpaper for Drywall
We’ve emphasized the importance of protective gear when sanding drywall, including goggles, a dust mask, and adequate ventilation to minimize dust exposure. To further mitigate dust, consider wearing a hat or protective headgear to keep drywall dust out of your hair. If you’ve never sanded drywall before, you’ll quickly realize that drywall dust can infiltrate every nook and cranny, so minimizing its spread is essential.
When sanding, apply medium to light pressure and use smooth strokes or a circular motion to achieve an even finish. Angle your hand sander slightly to avoid over-sanding in one area. For electric sanders, start with the lowest power setting and increase the speed as needed.
Prep, Cover, and Protect for Drywall Sanding Dust
Take the necessary precautions to prevent drywall dust from spreading to other areas in your home improvement project. Cover outlets, doorways, and windows to contain the dust. Consider using sanding screens, which are more durable and allow dust to pass through, reducing airborne dust that requires cleanup.
Don’t Rush, Take Your Time!
For impeccably painted drywall walls and ceilings, adhering to proper sanding techniques is essential. Avoid rushing, as sanding drywall is a meticulous process that takes time. By following these steps diligently, you’re on the path to achieving stunning walls and ceilings.
If possible, use a sanding block with a sanding screen instead of regular sandpaper. The market constantly introduces new and improved tools and techniques, so keep an eye out for time-saving innovations. Your back will thank you in the morning.
