Drywall dust released when sanding or cutting drywall sheets contains substances such as silica, gypsum, and mica – all of which can irritate your airways and cause discomfort. From my experience, drywall dust can collect on floors, windows, doors, walls, carpets, grout lines, etc., if you do not sand and clean the right way. So, how do you clean up drywall dust?
Open your windows to ventilate the house, then sweep the drywall dust into a pile on the floor before disposing it in dust bags. Vacuum the floor thoroughly, then mop it to clean up all the drywall dust. Wipe all surfaces in the house with a damp piece of cloth and keep the house well-ventilated.
Since drywall dust particles are very tiny, I recommend you use a shop vac with strong suction and great airflow – such as the Dustless D1603 Shop Vac – for the best results or the Dewalt Dust Extractor for more Commercial (Heavy Duty) Use. Those are what I use on the job.

Cleaning Drywall Dust
Before cleaning, wear a dust mask to protect yourself from inhaling harmful dust. I recommend the NASUM Reusable 8200 Face Cover for both drywall DIYers and professionals.
Here’s how to clean up drywall dust
Time: 5 minutes
u003cstrongu003e1. Open all the windows in your houseu003c/strongu003e
Open the windows and doors in your house to increase ventilation and allow fresh air into the house. Also, ensure that all the vents, heating, and air conditioning systems are switched off. This will keep the least amount of drywall dust circulating in the house while you clean it up.u003cbru003eu003cstrongu003eu003cuu003eu003cstrongu003eu003cmarku003eImportantu003c/marku003eu003c/strongu003eu003c/uu003eu003c/strongu003e: Wear a dust mask or a respirator to avoid inhaling the harmful drywall dust that might get kicked up in the air during the cleaning process.
u003cstrongu003e2. Place a fan at the window pointing outsideu003c/strongu003e
Since you’re going to sweep some of the u003ca href=u0022https://airlucent.com/black-dust-around-air-vents/u0022u003edust into piles and collect it, some dust will spread into the airu003c/au003e. Placing a fan at the window and setting it to face outside is a great way to direct most of that dust outside. (A good portable fan such as the u003ca href=u0022https://www.amazon.com/dp/B004IS6JBY?th=1u0026amp;linkCode=sl1u0026amp;tag=airlucentcom-20u0026amp;linkId=41da4752a80272ced20b2102c5c23fd9u0026amp;language=en_USu0026amp;ref_=as_li_ss_tlu0022u003eu003cuu003eLasko 20u0022 High-Velocity Quick Mount Fanu003c/uu003eu003c/au003e is great for this kind of job.)u003cbru003eThis step will be more efficient if you could open two or more windows, and if possible, you can put a fan in each. But the open windows would still work if you don’t have many fans in your house.
u003cstrongu003e3. Sweep and remove the bulk of the drywall dustu003c/strongu003e
Sweep most of the drywall dust into a pile using a broom and collect it in dust bags using a dustpan. You might want to spray a water mist onto the dust to make it less airborne.u003cbru003eKeep in mind that you’ll not be able to u003ca href=u0022https://airlucent.com/keep-dust-from-coming-out-of-vents/u0022u003eget all the dustu003c/au003e this way, but you will get most of it. Collect the drywall dust in a garbage bag or pail, then wait for it to settle for about 15 minutes before proceeding to the next step.
u003cstrongu003e4. Vacuum the floor and other surfacesu003c/strongu003e
Use a u003ca href=u0022https://airlucent.com/shop-vac-for-drywall-dust/u0022u003eu003cuu003egood vacuum for drywall dustu003c/uu003eu003c/au003e such as the u003ca href=u0022https://www.amazon.com/Dustless-Technologies-D1603-Wet-Vacuum/dp/B00QMCCZN0?amp;linkCode=ll1u0026amp;tag=airlucentcom-20u0026amp;linkId=b26631f68ecee2c275591f49d4c67a7au0026amp;language=en_USu0026amp;ref_=as_li_ss_tlu0022 target=u0022_blanku0022 rel=u0022noreferrer noopeneru0022u003eDustless D1603 Shop-Vacu003c/au003e because these are made to collect tiny particles such as drywall dust, or use a brush attachment u003ca href=u0022https://amzn.to/3yxcMOnu0022 target=u0022_blanku0022 rel=u0022noreferrer noopeneru0022u003elike this one from Hyde Toolsu003c/au003e and vacuum from top to bottom, left to right, and move gradually because drywall dust usually clings to walls.u003cbru003eIf you sprinkled water onto the dust, you might want to u003ca href=u0022https://amzn.to/39FqTGXu0022 target=u0022_blanku0022 rel=u0022noreferrer noopeneru0022u003euse a strong dry/wet shop vacu003c/au003e to clean up the drywall dust without clogging the HEPA filters.
u003cstrongu003e5. Clean the floor with a mop and wateru003c/strongu003e
After running your shop vac on the floor, the final step is cleaning with a damp cloth or a wet mop – but according to the type of flooring or surface you have. For example, use a microfiber cloth if you’re cleaning hardwood flooring. For concrete flooring in your garage, use u003ca href=u0022https://amzn.to/3FvSqGRu0022 target=u0022_blanku0022 rel=u0022noreferrer noopeneru0022u003ea commercial wet mopu003c/au003e to clean drywall dust residue.u003cbru003eThe damp cloth will easily pick up the dust residue, and you will also not have to stress about it turning into mud. Use the damp cloth to wipe the drywall dust from rough surfaces such as masonry and tile grout.
u003cstrongu003e6. Ventilate the roomu003c/strongu003e
The last step is to ventilate the room adequately before using it. Also, check to ensure no new u003ca href=u0022https://airlucent.com/how-often-to-dust-house/u0022u003edust particles have settled onto other surfaces in the houseu003c/au003e before using it.

Note: If you don’t wear a mask or a respirator and are exposed to drywall dust frequently and for an extended period, you might develop long-term respiratory problems.
Is it OK to vacuum drywall dust?
You can vacuum drywall dust but not use a regular household vacuum cleaner. Use a good shop vac to clean up fine drywall dust, or make sure you fit your regular vacuum with a heavy-duty HEPA filter to clean up drywall dust effectively.
The problem with a regular vacuum cleaner is that when you use it to get rid of the fine dust, the bags and filters get clogged quickly, making the vacuum spew dust back into the air.
Dust that fills up the air in your house can lead to respiratory problems, especially if you are not wearing a dust mask.
Your machine will also overheat when collecting fine drywall dust and can easily get damaged.
How To Remove Drywall Dust Before Painting
Okay, so we’ve learned how chalky drywall dust can be and how to clean it up generally. But in most cases, you’ll need to properly prepare and clean the drywall before painting over it. If you don’t remove the drywall dust properly, you will trap it with paint, and the wall will be bumpy and unattractive. So use the following steps to remove drywall dust before painting over it:
- Use a dustless shop vac to ensure all the fine particles are trapped and not blown back into the room. The brush attachment will be ideal for this step as you moved it slowly up and down and left and right to ensure you cover the entire area evenly.
- Follow with a microfiber cloth or a quality dust rag.
- Now you will use a wet sponge with cold water. Rub evenly in sections to absorb all the dust or to push it down the wall to the floor. Be sure to rinse after each small section to ensure you are using clean water in each section. If you are doing a large room, change the water every 10 feet or so.
- Wait for the drywall to completely dry, then you can use a black rag or shirt to rub on the wall to test if any white dust is coming off. If so then repeat the wet sponge run down.
Remove Drywall Dust on Concrete Floors
If you’re working with sheetrock with its dust falling on the concrete floor, it is best to keep the floor a little wet to trap the dust easily. Concrete floors don’t scratch easily, so you’ll be able to clean up drywall dust by scraping up the mud from the floor with a trowel.
Apart from the trowel, you’ll need some water in a spray bottle, a sponge, and a piece of cloth or microfiber pad.
Here’s the best way to clean up drywall dust from concrete:
Scrape up excess drywall mud from the concrete floor using a trowel, then spray some water on the dirty spots. Scrub the floor with a sponge, adding more water to any stubborn drywall dust spots and repeating the process. Wet-mop the floor using a rug and keep your house well ventilated.
Alternatively, if the sheetrock dust isn’t much, vacuum it off the floor using a dry-wet shop vac with a brush attachment. Mop the floor with a wet microfiber pad to remove any particles of drywall compound that remain on the concrete.
Remove Drywall Dust in Carpet
Carpets can absorb dust that can become very difficult to clean up. If, for some reason, sheetrock dust got its way into your carpet, you might want to rent a carpet cleaning machine to be able to get rid of it effectively.
Here’s how to clean up drywall dust from carpet:
- Dampen the carpet with clear water.
- Run a carpet cleaning machine in small sections.
- Repeat the process to remove all the drywall dust particles from carpet fibers.
- Allow the carpet flooring to dry completely before using the room.
If you’re working on a home improvement project, you might want to remove the carpet first to prevent it from absorbing too much drywall dust. Alternatively, use duct tape to cover it with heavy-duty plastic sheeting held down on the edges. Once you’re done, simply fold away the plastic sheeting with the drywall dust and dispose of it safely.
Remove Drywall Dust on Doors, Windows, and Ceilings
Drywall dust goes airborne very easily and can settle on doors, windows, ceilings, and inside grout lines on your floor tiles. Cleaning the compound and dusting off these surfaces depends on the material.
- Doors: For doors, wipe the dust off the surface with a damp cloth then allow them to dry. Wipe with a clean piece of microfiber cloth to remove any streaks or lines left on your doors.
- Windows: Most windows have glass panes, so gently wipe them with soapy water and a soft microfiber cloth. Rinse with clean water, then wipe them with WD40 to remove any streak marks.
- Ceilings: If your ceiling is sheetrock, do not sprinkle water on it. Simply dry-wipe it or use a brush attachment with a long hose on your vacuum to clean up the drywall dust from the ceiling.
Use a Dust-free Drywall Sander to Prevent Dust
If you frequently deal with drywall dust or work in such an environment, you might want to invest in the right equipment to help reduce the amount of drywall dust released into the air. Dust-free sanders such as this popular one from WEN are a great example of tools you can start using to prevent exposure to such construction dust.
Here are some of the best dustless tools for drywall applications:
- Dust bubble drill- this drill enables you to drill without dust.
- Abranet ace HD film
- HYDE dust-free sponge sander- this one works best on flat surfaces, including wood.
- Abranet Max Sponge – this is a net that is suited for the wood industry as it is substantially dust-free.
Apart from dust-free sanders, another option I found to work great is wet-sanding drywall sheets. It goes a long way in preventing dust from contaminating the air in the house. All you need is to add a wet-sanding attachment to your drywall sander and you’ll be able to get rid of the drywall dust easily.
Using the correct tools greatly reduces the amount of work, especially during the clean-up stage.
Is Drywall Dust Dangerous and Flammable?
When in small amounts, drywall dust is not exactly toxic to the body. This means that it will not cause long-term diseases. However, you should know that it can irritate some parts of the body, such as the throat. This is because drywall dust has a chemical compound known as gypsum.
Gypsum is non-flammable- generally, drywall dust cannot catch fire easily.
Gypsum has the same effects as chlorine in swimming pools, as they have approximately similar pH of 7.7. This is why when drywall dust comes into contact with your eyes, you may feel irritation for a short while.
If you don’t wear a mask or a respirator and are exposed to drywall dust frequently and for an extended period, you might develop long-term health problems.
Consult your doctor if you think you’re exposed to drywall dust for prolonged periods.
