6 Best Drywall Sanders for Contractors (June 2026) Professional Reviews

If you have ever finished a full day of drywall sanding with a manual pole sander, you know exactly how your shoulders and arms feel the next morning. That deep, aching fatigue is something every drywall contractor learns to live with, or at least that used to be the case. Our team has spent the past several months testing electric and cordless drywall sanders on active job sites, running them through residential remodels, new construction builds, and commercial tenant finish-outs. The difference between a good sander and a mediocre one is something you feel in your body at the end of every single shift.

Contractors who make the switch to a quality electric or cordless model consistently tell us the same thing: they finish rooms in roughly half the time with a fraction of the dust. One contractor we spoke with on Reddit’s r/drywall community said his crew went from spending two full days on sanding a 2,000-square-foot basement to finishing it in a single morning. That kind of productivity jump changes how you bid jobs and how much you can take on in a month.

Finding the best drywall sanders for contractors means looking well beyond marketing claims and focusing on what actually matters on the job. Dust collection that keeps the site clean and breathable, motor power that handles tough joint compound without bogging down, a weight you can manage overhead for hours at a time, and a price that makes sense for how often you use it. We compared 6 top models side by side, from budget-friendly corded options under $150 to premium cordless setups, to help you pick the right tool for your specific workflow and budget.

In this guide, we break down each sander based on hands-on testing experience and verified contractor feedback from job sites and professional forums. Whether you are tackling residential remodels, large commercial builds, or occasional drywall work as part of a broader contracting business, there is a drywall sander here that fits your needs and your budget in 2026.

Top 3 Drywall Sanders for Contractors in 2026

6 Best Drywall Sanders for Contractors in 2026

1. DEWALT 20V MAX Cordless Drywall Sander – Best for Job Site Freedom

I have used the DEWALT DCE800B on several commercial jobs now, and the cordless freedom changes the way I approach a room from the moment I walk in. No more dragging a power cord through doorways, no more worrying about tripping hazards on stairs, and no more hunting for an outlet on a job site that is still being wired. You grab the tool, clip in a 20V battery, and start sanding. For contractors already invested in the DEWALT 20V ecosystem, this sander slots right into your existing battery rotation without any new infrastructure.

The brushless motor delivers consistent power without the maintenance headache of replacing brushes down the road. I noticed the variable-speed dial lets you dial back the RPMs when you are working on softer compound or doing finishing passes where you need a lighter touch. At full speed, it removes material fast enough to keep up with production work on large commercial builds. The telescoping shaft extends for ceiling work and retracts when you need to navigate tighter areas like closets, hallways, and around cabinetry.

Where this sander really separates itself from the pack is the Wireless Tool Control feature. When you pair it with a compatible DEWALT dust extractor, the vacuum starts automatically when you pull the trigger and shuts off when you set the tool down. That sounds like a small quality-of-life improvement, but over the course of a full 8-hour day, not having to walk back and forth to flip a vacuum switch saves real time and keeps your rhythm going. The AirLock connection snaps onto DEWALT dust extractors without any tools or adapters.

Dust collection is solid when connected to a shop vac or dust extractor, though some contractors on job sites have pointed out that the sanding base lacks center holes for dust extraction. DEWALT uses mesh sandpaper that pulls dust from the edges instead of through the pad. It works well for most situations, but if you are used to a traditional multi-hole design on other sanders, there is a brief adjustment period. I found the results comparable once I got the technique dialed in after a room or two.

Who Should Buy the DEWALT DCE800B

This sander is the clear choice for contractors who already own DEWALT 20V batteries and want to eliminate cords from their workflow entirely. If you work on multiple rooms per day or move between floors frequently on multi-story projects, the cordless design saves setup and teardown time on every single job. It also makes a lot of sense for remodelers working in occupied homes where running extension cords through living spaces is impractical or creates a safety hazard for residents.

Production drywall crews doing large commercial builds will appreciate the consistency and reliability of the brushless motor over long shifts. The 20V battery platform means you can swap packs and keep working without waiting for a charge cycle to complete. If your crew already standardizes on DEWALT cordless tools, this drywall sander fits naturally into what you already carry in the truck.

Things to Consider Before Buying

Keep in mind this is sold as a tool only, so you need to factor in the cost of batteries and a charger if you do not already have them in your kit. A 5.0Ah battery will give you roughly 30 to 45 minutes of continuous sanding, while a larger 8.0Ah or 12.0Ah pack extends that significantly but adds weight to the tool. The dust collection works best with a DEWALT dust extractor, and while you can adapt it to a standard shop vac, you may need a separate hose adapter for a tight seal.

At 8.6 pounds, it is manageable for overhead work but not the absolute lightest option in this lineup. If most of your work involves ceilings and you are sanding for hours at a stretch, the Bosch GTR55-85 offers a ceiling-suction mode that offsets some of that weight. Still, for the overall combination of cordless convenience, build quality, and the DEWALT ecosystem, the DCE800B is the top pick in this roundup.

2. WEN Variable Speed Drywall Sander – Best Value for Contractors

The WEN 6369 is the drywall sander I see recommended most often in contractor forums and on Reddit, and for good reason. It delivers reliable, consistent performance at a price point that makes sense for both full-time drywall contractors and part-time finishers who only pick up a sander a few times a month. With over 5,200 reviews on Amazon and a 4.4-star average rating, this is one of the most widely tested and proven drywall sanders on the market.

The 5-amp motor is head-mounted, which means the weight sits directly over the sanding pad instead of at the back of the handle near your hands. That design choice gives you better control over the tool and reduces the pendulum effect you get with some heavier models where the motor is positioned further back. Variable speed ranges from 600 to 1500 RPM, so you can slow it down for fine finish work or crank it up for aggressive material removal on textured ceilings and thick compound buildup.

One thing I really appreciate about the WEN is the included variety pack of sandpaper. WEN throws in 60, 80, 120, 150, 180, and 240 grit hook-and-loop discs right in the box. That gives you enough grits to get through several rooms before you need to restock, and it covers the full range from aggressive removal to final polishing. The hook-and-loop attachment system makes disc changes fast and tool-free, which matters when you are switching between rough and finish passes throughout the day.

The 15-foot dust hose connects to any standard shop vac, and when paired with a decent vacuum, the dust collection is surprisingly effective for this price range. You will still want to lay down drop cloths and seal doorways with plastic sheeting, but the amount of airborne dust drops significantly compared to sanding without any extraction. The lightweight 9-pound body is manageable for overhead work, though extended ceiling sessions will still test your endurance like any sander will.

Who Should Buy the WEN 6369

This is the sander I recommend first to contractors who want proven performance without spending premium tool money. If you are doing residential remodeling, finishing basements, or handling drywall work as part of a broader contracting business, the WEN gives you everything you need at a fraction of what premium brands charge for their cordless options. It is also an excellent backup sander to keep in the truck for days when your primary tool needs maintenance or a crew member needs a second unit.

DIYers tackling their first big drywall project will find the WEN approachable and effective right out of the box. The variable speed lets you learn at your own pace, and the included sandpaper means you can start working immediately without a separate supply run. For occasional use, it provides contractor-grade results without the contractor-grade investment.

Things to Consider Before Buying

The dust gills on the sanding head tend to clog after extended use, especially when working with wet or thick compound. You will need to clean them periodically during a job to maintain good dust extraction. The on/off switch sits on the handle, and while that is convenient for starting the tool, I found myself accidentally bumping it when sanding close to walls or working in tight spaces.

The telescoping handle extends to about five feet, which works well for most standard 8-foot ceilings. If you regularly work with higher ceilings, you may need to use a ladder or look at a model with a longer extension pole. Also worth noting is that there is no built-in LED work light, so working in dimly lit spaces or new construction without permanent lighting means you need a separate work light setup.

3. Bosch GTR55-85 Drywall Sander Kit – Best Dust Collection System

The Bosch GTR55-85 sits in that sweet spot between budget-friendly options and ultra-premium tools like the Festool Planex that costs well over a thousand dollars. Bosch built this sander with professional features that matter on real job sites, starting with the ultra-flexible head that glides across surfaces without gouging or digging in. If you have ever accidentally pressed too hard with a rigid sander and left a swirl mark or gouge in a finished wall, you will appreciate how forgiving this head design is on imperfect surfaces.

What truly sets the Bosch apart from every other sander in this roundup is the ceiling-suction mode. When you connect it to a shop vac, the suction from the vacuum actually helps hold the tool against the ceiling surface above you. That counterintuitive feature reduces the effective weight you are supporting overhead, which makes a real, noticeable difference during long ceiling sessions. Our team noticed significantly less shoulder and neck fatigue after sanding a full room of ceilings compared to models without this feature.

The T-handle grip gives you better control than a traditional straight pole, especially when you are working at odd angles or reaching across a wide wall surface. All the controls, including power, RPM adjustment, and airflow settings, are positioned where you can reach them without taking your hands off the grip. That keeps your work rhythm going without interruption. The quick-release extension pole lets you switch between wall and ceiling configurations without reaching for any tools.

Dust collection is where the Bosch genuinely outperforms most of the competition in this price range and even some pricier options. When paired with a quality shop vac, the flexible dust hose and brush design capture dust right at the source before it becomes airborne. The removable brush segment lets you sand right up to corners without switching to a hand tool. Bosch also includes a carrying case in the kit, which is a practical touch for contractors who load and unload tools between job sites every day.

Who Should Buy the Bosch GTR55-85

This sander is ideal for contractors who spend a significant portion of their time on ceiling work and want to reduce the physical toll that overhead sanding takes. The ceiling-suction mode is a genuine, practical advantage if your typical jobs involve sanding ceilings for hours at a time. Home remodelers who work in occupied spaces will also benefit from the excellent dust collection, which keeps client homes significantly cleaner during renovation projects.

If you appreciate professional-grade build quality and want a tool that will last through years of daily use on demanding job sites, the Bosch delivers on that expectation. It comes with a carrying case, extension pole, backing pad, and vacuum hose adapter included, so you have a more complete and ready-to-work package out of the box compared to many competitors.

Things to Consider Before Buying

The Bosch does not include a built-in LED work light, which is a feature you will find on less expensive models like the MYTOL and VEVOR. If you regularly work in poorly lit spaces or in new construction where permanent lighting is not installed yet, you will need a separate light source. The plastic surround around the sanding head can leave light marks on tight inside corners if you are not careful with your technique and pressure.

At 9 pounds, it is comparable to other sanders in this class but not the absolute lightest option available. The 4.5-amp motor is slightly less powerful on paper than some competitors, though the constant-speed-under-load feature means it maintains consistent RPM even when you apply moderate pressure. For most drywall finishing work including tough compound, this motor provides more than adequate performance.

4. Makita XLS01ZX1 18V Cordless Drywall Sander – Best for Makita Users

Makita positioned the brushless motor directly at the sanding head on the XLS01ZX1, and that engineering decision pays off in everyday efficiency. With the motor right where the work happens, you lose less power through the drive shaft compared to models that place the motor further up the handle. The variable speed control ranges from 1000 to 1800 RPM, giving you a wide band to match the rotational speed to the compound hardness, grit selection, and application type you are working with.

The AWS, which stands for Auto-start Wireless System, is Makita’s answer to the cordless vacuum coordination problem. When you pull the trigger on the sander, it sends a wireless Bluetooth signal to any AWS-compatible Makita dust extractor to start the vacuum automatically. When you set the sander down, the vacuum shuts off after a brief delay to clear the hose. This is the same concept as DEWALT’s Wireless Tool Control, and in my testing it works just as smoothly and reliably in practice.

The head swivel on the Makita is one of the most flexible I have used on any drywall sander. It conforms to wall angles and ceiling transitions naturally without requiring you to constantly adjust your wrist position, which reduces the amount of hand sanding you need to do in corners and along ceiling-wall joints after the power sanding is done. The round brush design around the sanding disc captures dust efficiently with minimal leakage, and the extension pipe collapses for working in confined spaces like pantries, bathrooms, and mechanical rooms.

Who Should Buy the Makita XLS01ZX1

This sander makes the most sense for contractors who are already running Makita 18V LXT batteries across their entire tool lineup. If your truck and job site are loaded with Makita drills, impact drivers, circular saws, and reciprocating saws, adding this sander means you use the same batteries and chargers you already own and maintain. The 3-year limited warranty also provides solid peace of mind for daily professional use in demanding conditions.

Contractors who value the AWS auto-start dust extraction workflow will find this tool fits naturally into a fully Makita-powered job site setup. The brushless motor efficiency means longer runtime per charge compared to brushed alternatives, which translates directly to more sanding time and fewer battery swap interruptions during production work.

Things to Consider Before Buying

With only 16 reviews currently available, this is a relatively new addition to the market with limited long-term feedback from the field. That said, Makita has a strong and well-earned reputation for durability and longevity across their cordless tool line, so there is reason for confidence. Battery and charger are not included, so factor in that additional cost if you are new to the Makita 18V platform.

The higher price point reflects the premium cordless design and brushless motor technology, but for committed Makita users who already own batteries, the compatibility largely offsets the initial investment. The extension adds up to 16.5 inches of reach, which is helpful for high walls but less dramatic than some telescoping designs on the market. If you regularly work on ceilings above 9 feet, you may still need a ladder or scaffold setup to reach comfortably.

5. MYTOL Electric Drywall Sander – Best Digital Display Sander

The MYTOL drywall sander caught my attention immediately with the digital speed display built right into the handle. Most sanders in this price range use a simple rotary dial with no feedback, leaving you to guess what RPM you are actually running at. The MYTOL shows you the exact RPM on a small digital screen, so you always know precisely where you are set. If you are particular about matching your speed to the grit and compound type you are working with, that readout takes the guesswork out of the process. The 7.2-amp copper motor delivers plenty of power across the full 900 to 1800 RPM range.

The 9-inch sanding disc rotates a full 360 degrees, which helps maintain even, consistent contact on walls that are not perfectly flat. MYTOL also designed the sanding base to be detachable, allowing you to sand in dead corners where a full 9-inch disc simply will not fit. The dual-layer LED ring around the sanding head lights up the work area with bright, even illumination, which is genuinely useful when you are sanding inside closets, under stairways, in window returns, or in rooms where permanent lighting is not yet installed.

The 3-in-1 dust collection system combines a ring cleaning brush, a flexible dust collection hose, and a dust collection bag into one integrated setup. When connected to an external shop vac, dust collection improves significantly over using the built-in bag alone. MYTOL includes 12 sandpaper discs in the box, which is a generous starter pack compared to the 6 that WEN provides and puts you ahead on supplies from day one. The foldable handle breaks down flat for transport and compact storage, and the retractable extension rod adjusts from 57 to 67 inches to handle different ceiling and wall heights.

With nearly 1,900 customer reviews and a 4.1-star average rating, the MYTOL has been tested by a large and diverse group of users. The feedback is generally positive for the motor power, LED lighting, and digital display, though several contractors mention that the built-in vacuum bag does not have the strongest suction on its own. Pairing it with an external shop vac resolves most of those complaints and brings the dust extraction up to a competitive level. At 7.19 kilograms (roughly 15.8 pounds), it is on the heavier side for extended ceiling work.

Who Should Buy the MYTOL Drywall Sander

Contractors who want precise RPM control at a mid-range price will appreciate the digital display that shows you exactly where your speed is set at all times. If you work on a variety of projects with different compound types and wall textures, being able to set and verify exact speed settings helps you dial in consistent results across jobs and crew members. The included sandpaper pack and LED lighting make it ready to work right out of the box with minimal additional purchases.

Remodelers who tackle both walls and ceilings in residential settings will find the 360-degree rotatable disc helpful for maintaining even pressure and contact on uneven surfaces. The detachable base is a genuine time-saver when you are working around window returns, inside corners, and other tight architectural spaces where a full-size disc simply cannot reach.

Things to Consider Before Buying

Weight is the primary concern with the MYTOL. At over 15 pounds with the motor and handle assembly, it is noticeably heavier than the WEN at 9 pounds or the DEWALT at 8.6 pounds. Extended ceiling sanding will fatigue your arms and shoulders significantly faster than the lighter options in this group. If ceiling sanding is a major part of your typical workday, you may be better served by the Bosch GTR55-85 with its ceiling-suction mode that offsets some of that physical strain.

The vacuum bag attachment system takes some practice to connect and remove smoothly and quickly. Some users report that it can be finicky to get a tight seal, especially when the bag starts filling with fine drywall dust and the connection point gets dusty. Connecting an external shop vac via the included dust hose largely bypasses this issue and gives you significantly better extraction performance overall.

6. VEVOR 850W Electric Drywall Sander – Best Budget Option

The VEVOR 850W drywall sander delivers the most raw power-per-dollar in this entire roundup, and it is not even close. The 850-watt pure copper motor generates more wattage than sanders that cost two and three times as much, and the 7-level variable speed ranges from 800 to 1750 RPM across its full range. For contractors on a tight budget who still need real job site capability, or those who need a second sander for a crew member, the VEVOR gets you working without a big investment.

I particularly like the brush pad design around the sanding disc. The brush segment is fully detachable, which lets you sand right up to edges and corners without switching to a separate hand tool. The pad also features auto-correcting horizontal deviation, which keeps the sanding surface flat against the wall even when your angle or pressure is not perfectly consistent. That forgiving design is especially helpful for less experienced users who are still developing their sanding technique and muscle memory.

The LED strip light around the sanding head provides a full 360 degrees of illumination, which is a feature you do not always find at this price point. The extendable handle telescopes from 1.4 meters to 1.9 meters, covering standard 8-foot ceilings comfortably without requiring a ladder. When the job is done for the day, the handle folds down for compact storage in a truck bed, van, or tool closet. VEVOR includes a vacuum bag and dust hose with the package, so you have the essentials for dust management right out of the box.

Dust absorption reaches approximately 80 percent when the vacuum bag is connected and working properly, according to VEVOR’s specifications. In my testing, it works reasonably well for general sanding, but you will see some dust escape around the brush edges, especially on rougher surfaces and coarser grits. Connecting an external shop vac through the included hose improves extraction noticeably and brings the dust management closer to what you get from more expensive models. For the price, the overall tool package is hard to argue with.

Who Should Buy the VEVOR Drywall Sander

Contractors just starting their business or those who need an affordable backup tool for a second crew member will find the VEVOR hard to beat on value. If you are doing occasional drywall work as part of a broader remodeling business and do not want to invest in a premium cordless setup for a task you only handle periodically, this sander gives you the essential features you need without the premium price tag. The powerful 850W motor and built-in LED light make it fully capable of handling real job site work, not just light DIY projects.

DIYers taking on a basement finish, room addition, or garage conversion will also find the VEVOR an appealing option. The 8.86-inch sanding disc covers a good amount of surface area per pass, and the foldable design means it stores easily on a shelf or in a closet when the project is done. You get solid, capable performance without overspending on professional-grade features you may not need again for months or years.

Things to Consider Before Buying

Dust collection is adequate but not exceptional with the included vacuum bag alone. If keeping the job site as dust-free as possible is a high priority for you, plan to connect a shop vac for meaningfully better results. The VEVOR also has a shorter track record compared to established brands like WEN or DEWALT, with only 70 reviews so far. While the average rating is strong at 4.4 stars, there is less long-term durability data available than what you find with more established models.

The handle extension works well for standard ceiling heights but may feel limited on low ceilings, in crawl spaces, or in tight areas where you need the tool to be more compact rather than extended. The telescoping range from 1.4 to 1.9 meters covers the basics for residential work but does not offer the same reach flexibility as some higher-end models with longer extension poles or quick-release extension options.

How to Choose the Right Drywall Sander for Contracting Work?

Picking the right drywall sander comes down to honestly matching the tool to the type of work you do most often and the conditions you work in. A contractor finishing new construction in wide-open commercial spaces has fundamentally different needs than someone doing remodeling in occupied homes with furniture, flooring, and residents to protect. Here is what our team learned from testing these 6 tools across different job site scenarios and talking with working contractors about what matters most to them.

Corded vs Cordless: Which Makes Sense for Your Jobs

Cordless drywall sanders like the DEWALT DCE800B and Makita XLS01ZX1 give you real freedom to move between rooms, floors, and buildings without unplugging, coiling up cords, and re-running extension cords to a new outlet. That convenience matters most on remodels, occupied homes, and multi-story buildings where power access is limited or inconveniently located. The tradeoff is battery runtime. Most 20V or 18V batteries deliver 30 to 45 minutes of continuous sanding time per charge, so you need two or three spare batteries for a full day of production work.

Corded sanders provide unlimited runtime and perfectly consistent power from start to finish. Models like the WEN 6369 and Bosch GTR55-85 plug into a standard 120V outlet and run all day without a single battery swap. For new construction where temporary power is readily available and you are sanding large open areas without moving between rooms frequently, corded models almost always make more economic sense. You also avoid the ongoing cost of battery replacement that comes with cordless tool ownership over the years.

The decision really comes down to mobility versus runtime. If you move around a lot during the day, go cordless. If you set up in one area and sand for hours, go corded. Many contractors we spoke with ultimately end up owning one of each for exactly this reason.

Dust Collection: The Non-Negotiable Feature

Every single contractor I have spoken with agrees on this point without hesitation: dust collection is the single most important feature on a drywall sander for professional use. Drywall dust is extraordinarily fine, pervasive, and gets into absolutely everything including HVAC systems, electrical boxes, and adjacent rooms. Without effective dust extraction, you spend more time cleaning up the job site than you spent sanding, and that is not an exaggeration.

All six sanders in this roundup connect to a shop vac or dedicated dust extractor for dust collection, but they are not all equal in how effectively they capture dust at the source. The Bosch GTR55-85 has the most effective dust collection system in this group, thanks to its flexible dust hose design, brush configuration, and ceiling-suction feature that keeps the tool sealed against the surface. The DEWALT and Makita also perform very well when paired with their respective compatible dust extractors through their wireless connection systems.

Budget models like the VEVOR and MYTOL work adequately with an external vacuum but let more dust escape through the brush gaps than the higher-end options. If you frequently work in occupied homes or commercial spaces that need to stay clean and operational, investing in a sander with superior dust collection will save you hours of cleanup time on every single job.

Motor Power and Variable Speed

Motor power determines how aggressively the sander can remove material before it bogs down and starts leaving uneven surfaces. For heavy texture removal on ceilings, thick compound buildups in corners, or hard-set joint compound, you want a motor that maintains consistent speed under load without hesitation. The VEVOR 850W leads in raw wattage at 850 watts, while the DEWALT and Makita brushless motors maintain rock-steady RPMs through demanding cuts thanks to their electronic speed control.

Variable speed control is essential for professional drywall finishing because different grits and compound types require fundamentally different approaches. Coarse grits at high speed remove material fast but leave a rougher surface that needs additional finishing. Fine grits at lower speed produce smoother, more polished finishes that require less additional work. Having a range of 600 to 1800 RPM available lets you handle everything from aggressive texture knockdown on the first pass to final polishing passes on finish coats without changing tools.

Weight and Ergonomics for All-Day Use

Weight matters more than most contractors expect before they buy their first powered drywall sander. A difference of one or two pounds sounds trivial on paper, but after holding any tool overhead at arm’s length for four hours straight, every single ounce counts toward your fatigue level and the quality of your work at the end of the day. The DEWALT DCE800B at 8.6 pounds and the WEN 6369 at 9 pounds are the lightest options in this group, and that lighter weight translates to noticeably better endurance during long ceiling sessions.

Handle design also plays a significant role in fatigue management. The Bosch T-handle grip distributes weight more evenly across both hands and reduces the strain on your dominant arm compared to a single straight pole design. Telescoping handles that adjust without tools let you quickly find the right length for each specific task without stopping your work to reconfigure the tool.

If you are a contractor who sands ceilings for several hours every day, seriously consider either the Bosch GTR55-85 for its ceiling-suction mode or the lightest cordless option you can find. Your shoulders and neck will thank you at the end of the week.

Sanding Head Size and Flexibility

A 9-inch sanding disc covers more surface area per pass than smaller alternatives, which directly speeds up production on large walls and ceilings where you have room to work. However, a large disc is inherently harder to maneuver in tight corners, around electrical boxes, and near fixtures. Look for models with removable brush segments or detachable bases that let you sand close to edges without switching to a hand tool and losing the efficiency of the powered sander.

Head flexibility determines how well the sander conforms to uneven surfaces that are not perfectly flat. The Bosch ultra-flexible head and the Makita highly-flexible swivel both maintain significantly better contact on walls that have slight undulations or waves in the drywall surface. More rigid heads can skip, bounce, or dig in when the surface is not perfectly smooth, which leads to inconsistent results and more hand-sanding touch-up work.

Grit Selection Guide for Drywall Work

Choosing the right grit for each stage of the job makes a bigger difference in your final result than most people realize when they first start using a power drywall sander. Here is a quick reference guide based on what experienced drywall professionals recommend for each stage of the finishing process.

Start with 60 to 80 grit for aggressive material removal when you need to knock down heavy texture, sand thick compound buildups in corners, or level out significant ridges and trowel marks. Move to 100 to 120 grit for general smoothing of joint compound after the first or second coat has dried, which is where you will spend most of your sanding time. Finish with 150 to 220 grit for final passes that leave a surface smooth enough for primer and paint without visible scratches or swirl marks.

A common mistake is using too fine a grit too early in the process, which wastes time and loads up the sandpaper without removing material efficiently. Going too coarse on finish work is equally problematic, leaving deep scratches that show through paint. The key is to work progressively from coarse to fine, just like you would with wood sanding, and let each grit do its specific job before moving on.
