Cause of black mold on drywall

Drywall is basically the best place for mold to grow. It loves growing on something that is made from gypsum which is a white colored powdery material that is encased in two soft papers. Paper is a great source of food for mold to take in and grow in. It loves making itself a home in a material such as this. Since drywall is quite large, it has plenty of room to make space for itself.

However, it can only grow in the presence of moisture. If your drywall has some moisture coming out of it, you’ll soon realize why there are small patches of mold all over it. It can be found in washrooms, basements, or even walls of your room where the waterlines go from. Since the material is so light, drywall takes in water very quickly and absorbs it into itself. It would take a lot of careful consideration before you begin clearing up the wall.

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 it’s 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 aren’t 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 it’s coming from. If there’s a leak, then it should be completely taken care of. There are different types of mold that will help clear out everything that’s 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, you’ll have to cut the piece that’s damaged and go from there. If the damage isn’t too extensive, the mold can be easily cleaned even if it’s inside or outside the wall.

Cutting off mold directly from the wall

There is a whole method for cutting out mold from the wall. It is pretty simple however since a wall is an obvious part of your house, you have to be extra careful while you clean it. The method initially begins with you measuring the area that is affected.

Before you do anything else, first measure the area that is filled with mold. Once you’ve measured it, mark it with a pencil or something that can be marked. This would make it easier for you to cut the exact area affected and nothing more. Take out a sharp cutter tool that easily cuts without you having to put extra force on it. Start cutting it over the marked lines so as not to stray from it and cut anything extra. Slowly remove the loose piece from the wall and quickly bag it in.

Once you’re done removing, clean the wall without the mold to try letting it go back to the way it was. Since drywall with a giant piece removed from it looks quite odd, you can even replace it with a new piece.

Removing black mold from the top of the wall

You can remove black mold from the wall pretty easily. The process starts by wearing a pair of glows and having a respirator with you to keep you away from spores. Since spores might get into your system, you have to take any kind of precaution you can to make sure nothing else happens. Take out some plastic and cover the floor with it. So any remains coming out of the wall will go straight on the plastic which can be cleaned pretty easily. In order to clean up the mold, make a solution.

The solution needs to have half a cup of bleach and a gallon of water. The water and bleach solution will be quite helpful in removing black mold right from the surface of the wall. There won’t be any stains left to clean up. Carefully apply the whole solution to the mildew so only that part is affected. Set it up for fifteen minutes so it thoroughly gets absorbed within and you can find its solution well.

Once the solution is deep within, wash the whole area with clean dishwashing liquid and water so it’s in there. Then make sure to rinse everything with water and let it dry. We’re sure that all signs of the mold will be gone when you do this.

Removing black mold from the inside

Comparatively, this is a quicker method and requires you to take extra precautions. Since mold is a little on the inside you might end up with some of the dry pieces to be cut out. Prepare by wearing goggles and latex gloves along with having some plastic on hand. Spread it all around the area in order to contain it so it doesn’t get out.

The method starts by placing an air scrubber around the area affected. This will thoroughly filter the air around the mold. A heap vacuum is required to be placed over the drywall so the spore, mycotoxins, and mycelium are contained within it. When you’re done with this, apply the plastic glow box method where you cut a piece of plastic that is four inches wider and longer than the molded area. Keep a mold adhesive over the plastic box on the mold so it doesn’t get into the air when you cut it. After this, take a razor and cut the sealed moldy area away from the wall. Then maneuver it right into a garbage bag.

How to clean and disinfect it

It’s critical to clean and disinfect the area after removing the mold to ensure that all spores are gone. Allowing a bleach combination to stay on the surface for fifteen minutes and cleaning it away with water is sufficient if the region only damaged the exterior of the drywall.

Extra precautions should be used if drywall had to be removed to eradicate the mold. First, apply benefact antimicrobial to all nearby drywall that isn’t impacted. Remove any spores that may be adhering to the unaffected regions with a HEPA vacuum. To ensure that no spores get into other parts of the house, HEPA vacuum the whole area you enclosed, including the floors.


Having black mold in our homes is quite a common problem in households. This is especially for houses that are located in relatively water-lined areas.

These places need to be authorized with care to make sure that you have clean and filtered air to breathe in. For something like, air purifiers are the best choice. They rid you of any mold that might be growing all over the place and keep you wanting more.
