Mold can cause serious respiratory problems and other illnesses, so it should be removed as soon as possible. The method of removing mold on drywall (also known as drywall, unplastered walls) depends on whether the drywall has been painted or not. If the wall has been painted, you need to clean it with water and detergent. If it has not been painted, the moldy dry wall should be removed because the surface is too porous so it is difficult to clean.
Steps
Walls that have been covered or painted

Create ventilation in the room. To get rid of mold, you need a chemical cleaner. These products come in many varieties that are toxic if inhaled, so you need to keep windows and doors open during the mold removal process. Absolutely do not direct the fan into the room to prevent mold spores from spreading everywhere. You can place a fan in an outward-facing window to expel harmful air from the room. In addition, you should also use a plastic sheet to cover the door to prevent mold spores from spreading to other areas of the house.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/84/Remove-Mpd-from-Drywall-Step-2-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-2-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/84/Remove-Mpd-from-Drywall-Step-2- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-2-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Protect the surrounding area. To prevent damage to your furniture from accidentally spilling chemicals or cleaning products, you should protect any items that don’t need mold treatment. Move furniture and decorations to a corner or out of the room. Cover the floor with newspaper or a plastic tarp and secure the covering with tape. Have a rag ready to wipe up any spilled cleaner.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/66/Remove-Mpd-from-Drywall-Step-3-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-3-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/66/Remove-Mpd-from-Drywall-Step-3- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-3-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Choose a detergent. Detergents range in strength from mild to strong, and can be in both natural and chemical forms. If you have small children or pets in your home, consider using a gentle, natural solution instead of a harsh chemical solution. In the case of a severe mold infection, stronger chemicals may be needed.
- Mix baking soda with water in a ratio of 1:5. Baking soda is the mildest and safest cleaning ingredient available commonly used to combat mildew.
- Use pure vinegar or vinegar mixed with water in the ratio 1:1. Vinegar is a little stronger than baking soda, but it’s still natural and safe to use in areas with small children and pets.
- Use an unscented detergent. One of the easiest ways to identify mold is a musty smell, so using an unscented cleaner will ensure that there are no other scents that would prevent you from detecting the smell of mold. Although it is a chemical product, the cleaner is relatively safe to use in areas with small children and pets. Mix detergent with a small amount of water.
- Use bleach. [1] X Research Source Some people recommend bleach, but others discourage it. People oppose bleach mainly because of its strength and potential toxicity when inhaled. Some people even argue that the effectiveness of bleach is not guaranteed. However, bleach remains one of the most powerful, effective and safe cleaning agents for treating painted drywall. Mix bleach with water in a ratio of 1:3.

Pour the cleaning solution into the spray bottle. Pour cleaning solution and water into spray bottle and shake well. Make sure the solution is evenly dissolved to be sure it is effective.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/eb/Remove-Mpd-from-Drywall-Step-5-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-5-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/eb/Remove-Mpd-from-Drywall-Step-5- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-5-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Spray a small amount of the solution onto the mold. Do not spray wet because too much humidity actually causes mold to grow instead of being destroyed. Spray the solution on the mold 1-2 times, making sure each area is covered with the solution but not so much that it drips.

Use an old toothbrush to scrub the mold. Dishwashers with a rough surface can also be used. Scrub until the stains or mold on the walls disappear.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/70/Remove-Mpd-from-Drywall-Step-7-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-7-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/70/Remove-Mpd-from-Drywall-Step-7- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-7-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Dry the wall. Mold can start to grow if you leave the walls damp. Therefore, you should point the fan at the wall to dry faster.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0a/Remove-Mpd-from-Drywall-Step-8-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-8-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0a/Remove-Mpd-from-Drywall-Step-8- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-8-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Paint anti-stain. If there are still stains on the wall even after scrubbing, you can apply a stain-resistant primer and topcoat to cover it up.

Cover the floor with plastic tarpaulin. As you clean, mold spores can fall off the drywall. To prevent them from falling to the floor, you should use a plastic tarp to cover the floor and surrounding objects. Use adhesive tape to secure the canvas.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/50/Remove-Mpd-from-Drywall-Step-10-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-10-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/50/Remove-Mpd-from-Drywall-Step-10- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-10-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Mark the moldy area on the wall. Use a pencil to draw an opaque square around the area where you see the mold. This area is usually larger than the stain itself and extends to at least two wooden wall beams behind the drywall. Removing the wall that is wider than necessary will increase the chances of removing invisible mold spores, and will also make it easier to replace the moldy wall.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/1c/Remove-Mpd-from-Drywall-Step-11-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-11-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/1c/Remove-Mpd-from-Drywall-Step-11- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-11-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a multi-purpose knife to cut moldy dry walls. Use the knife to make an incision along the drawn line, pointing the knife outward and away from the body while making the incision. Once the dry wall has come off, carefully remove it and place it under the plastic sheet so that the moldy side is on top.

Clean the room with a vacuum cleaner with a HEPA (high efficiency air filter) filter. Mold spores can be stirred up during cleaning, and a HEPA vacuum will help you get rid of them.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a3/Remove-Mpd-from-Drywall-Step-13-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-13-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a3/Remove-Mpd-from-Drywall-Step-13- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-13-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
If mold is present on the side of a door or window, have the person spray water on the door or window with a hose while leaving the interior walls open, and monitor for any water coming out. Sometimes it may take 5 minutes for the water to leak out. Once you’ve determined the location, you need to seal both the inside and outside of the wall to prevent moisture from entering (mold only occurs in damp places).
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/dc/Remove-Mpd-from-Drywall-Step-14-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-14-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/dc/Remove-Mpd-from-Drywall-Step-14- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-14-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
As recommended by experts, before replacing drywall, you should paint over the hole in the wall with an elastic paint like Kilz paint, and also paint on the back of the wall you plan to replace. Cut a new drywall section. Measure the hole in the wall with a tape measure and then use a multi-purpose knife to cut a new piece of drywall that will fit the measurements.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/1c/Remove-Mpd-from-Drywall-Step-15-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-15-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/1c/Remove-Mpd-from-Drywall-Step-15- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-15-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Place the new drywall patch in the hole. The new drywall must fit snugly and tightly.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/5a/Remove-Mpd-from-Drywall-Step-16-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-16-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/5a/Remove-Mpd-from-Drywall-Step-16- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-16-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Fix the new drywall array. Use drywall screws and screwdrivers to secure the drywall to the wooden beams in the back wall.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/64/Remove-Mpd-from-Drywall-Step-17-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-17-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/64/Remove-Mpd-from-Drywall-Step-17- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-17-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Fill seams with sealant. You’ll need to use sealant around the seams to help bond the new wall to the rest of the wall and seal the cracks in between.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/bf/Remove-Mpd-from-Drywall-Step-18-Version-3.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-18-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/bf/Remove-Mpd-from-Drywall-Step-18- Version-3.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-18-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Rub gently after the sealant has dried. 24 hours after filling, you can use sandpaper or a light sandblaster to smooth the dried filling.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/cf/Remove-Mpd-from-Drywall-Step-19-Version-2.jpg/v4-728px-Remove-Mpd- from-Drywall-Step-19-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/cf/Remove-Mpd-from-Drywall-Step-19- Version-2.jpg/v4-728px-Remove-Mpd-from-Drywall-Step-19-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a HEPA vacuum to vacuum the entire area. Mold spores can fall on the surrounding walls or on the floor, even if you’ve covered it with plastic tarpaulin. Use a HEPA vacuum to remove as many mold spores as possible.
Warning
- Seek professional help if you cannot handle the problem yourself. Black mold is particularly toxic and should be handled professionally. For other types of mold, if they spread in large patches on dry walls, you need to have a professional deal with them. You may need professional mold removal if your home is damp, if someone in your home has respiratory problems, or if mold continues to appear and spread.
- Always wear protective equipment when removing mold. Wear a disposable mask to protect yourself from inhaling too many mold spores. Wear goggles and rubber gloves to protect your eyes and skin from mold and any chemicals you use to remove mold.
