How To Remove Mold On Painted Drywall
If you find mold on drywall that is painted, its much easier to clean. Since paint provides a barrier on the drywall, the mold most likely hasnt penetrated the surface, meaning you just need a good cleaner and some elbow grease.
Before you start, make sure you identify the source of moisture causing the mold in the first place and fix the issue. Then, follow these steps to remove mold on painted drywall.
Dealing With Mold On Drywall
As we just said, since mold cannot be completely removed from drywall, the drywall must be removed and replaced. This must be done with care because cutting into moldy drywall causes mold spores to become airborne and spread.
The U.S. Environmental Protection Agency advises that if mold covers more than 10 square feet, a professional remediation company should be hired to remove the mold. If it is a smaller job that you plan to handle yourself and you have any health concerns, speak with your doctor to make sure it is safe for you.
First the work area must be prepared. Furniture and other items should be removed from the area if possible. Otherwise, they should be covered securely with sheets of heavy plastic to protect them from mold spores.
Plastic sheets should be taped over heating and air conditioning vents to prevent mold spores from entering your heating, ventilation and air conditioning system. Hi-hats hould also be covered with plastic.
The floor should also be covered with large sheets of plastic, to prevent the flooring from becoming contaminated with mold.
First the drywall should be sprayed with water to prevent mold spores from becoming airborne as the drywall is taken down. The moldy pieces of drywall should be enclosed in heavy plastic trash bags before you carry them through the house, so as to prevent scattering mold spores as you go.

How Do You Get Rid Of Mold And Mildew On Drywall
The first step to getting rid of mold and mildew in your home is to stop the source of moisture. Every living creature needs moisture in some shape or form in order to survive. Mold is no different to in this regard.
So, before you start removing the mold from your drywall, you need to stop the source of the moisture, whether it is a leaky window, or a pipe, if it is a roofing issue, or water vapor weeping through a concrete floor, you will have to fix the issue. If you do not then mold will start growing again immediately after it is removed.
Next, you need to gather your drywall mold removal gear. When you remove mold you will without-a-doubt stir up spores, and they will become airborne.
You need to wear protective gear, long sleeves, long pants, rubber gloves, a respirator mask, and safety glasses, perhaps a hood as well if you have long hair as you do not want mold spores getting in there.
You will also need to decide if you are going to try and save the wall, or just scrap the whole thing. Sometimes removing the whole thing is a more effective long term solution than the alternative.
If the wall is soft then moisture and mold has taken its toll and the structural integrity is just non-existent at this point.
You need to remove surface mold from the drywall first if you are going to attempt to make it safe. You will want to vacuum the whole area with a HEPA-equipped vacuum and a brush adjustment to ensure you break up the spores and remove as much as you can.
Removing Black Mold From Drywall
The approach starts with determining what is producing the mold in the first place and resolving the issue. If the problem is a small leak, make sure its corrected entirely before attempting to remove mold from drywall. You should also get an estimate of the size of the affected area at this stage. Only small portions of fewer than ten square feet should be tackled by homeowners who arent trained in black mold removal. This is a precaution you should take due to the potential health risks of mold.
Before we even begin with the process of removing mold, we need to make sure that we clear out the source that its coming from. If theres a leak, then it should be completely taken care of. There are different types of mold that will help clear out everything thats on it. It is the most severe kind of mold. If your wall is suffering from something like this, then the situation is beyond your control. Therefore before you begin, take a quick run-through and find what the scene looks like. If the damage is too far gone, youll have to cut the piece thats damaged and go from there. If the damage isnt too extensive, the mold can be easily cleaned even if its inside or outside the wall.
