The method used to remove mold from drywall may vary depending on whether the wall is coated or not. If the drywall is not coated, removing mold using water and cleaning agents may not work since it’s too porous. This means that cleaning it may only cause more harm than good. On the other hand, if the drywall is coated, then cleaning should be easy.

NB: Wear protective gear such as coveralls, gas mask, and hand gloves when cleaning.

If you find mold on your painted drywall, the good news is that you don’t have to replace it entirely. Unlike an unpainted drywall, the mold should just be on the surface and should not have penetrated into the wall itself.

You will easily notice mold in your drywall by its appearance. It may appear as black, white, or bluish patches on the wall. Black mold tends to be more common. For example, you may notice black spots on the siding. Once you identify the kind of mold you have, it’s time to prepare the area.

Remove any wall hangings, wallpapers, and other items. If they’ve been adversely affected by mold, consider disposing them of as cleaning can be a little more difficult. Removing these items will also give you enough space to work while removing mold and also protect them from potential damage.

It’s also important to protect the surrounding area. In addition to removing any decorations on the drywall, remove furniture and cover the floor with newspapers or drop cloth. Doing this will prevent anything you don’t intend to work with directly from getting damaged in case you accidentally spill cleaning chemicals.

Keep the room properly ventilated

When removing mold, it’s advisable to keep the room well ventilated. This is because large amounts of mold spores will be expelled during cleaning, and opening the windows in the room will help expel some of the spores. You can place a fan in the window facing outward to push mold-filled air outside the room.

Also, because the mold cleaning products you’re using may be harmful if inhaled, keeping the doors and windows open is important.

NB: Avoid opening doors that are adjacent to other rooms that don’t have mold. It might cause the mold spores to spread to other rooms.
