Mold on your interior drywall doesn’t just look unpleasant; it can also be a health hazard for you and your family. This is because the microscopic spores expelled can cause allergic reactions, asthma, or cause a person’s immune system to weaken.
Having mold in your home poses a health risk especially to small children, the elderly, and people suffering from respiratory illnesses or weakened immune systems. It’s therefore very important that it’s removed as soon as it’s noticed.
The method used to remove mold from your 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.
In this article, we are going to discuss how to remove mold from drywall.
NB: Wear protective gear such as coveralls, gas mask, and hand gloves when cleaning.
Prepare the area affected by mold
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.
Choose the most suitable mold cleaning product
There are many cleaning products and chemicals for cleaning mold. All you have to do is select the most suitable one. Mold cleaning products usually range from mild to potent, and often include both natural and chemical alternatives.
Your choice will depend on whether the mold problem you have is extensive, and whether you have small kids or in your house. If the mold problem is big, you might consider using more powerful cleaning products.
Here are the best mold cleaning products
- Baking soda + water solution – This is the cheapest, readily available, and one of the most effective mold cleaning products. It’s also a safe product to use in the house since its mild. It will help you get rid of black mold, white, and blue mold in no time. Mix one part baking soda with five parts water to make a mild solution.
• Unscented detergent – One of the best ways to identify mold in your home is by smell. This means you should only use an unscented detergent to ensure that there are no other smells that will interfere will your ability to detect its presence. You will combine unscented detergent with some water.
• Use a bleaching agent – Bleach is one of the strongest mold cleaners for removing mold in drywall. Although some people object its use due to how potentially harmful it can be to breathe in and how harsh it is, it’s still a very effective mold remover. Combine a part bleaching agent with three parts water.
• Use commercial cleaners – There are a number of commercial mold cleaning solutions on the market. Most of them are very effective in removing mold from drywall, so you should consider trying them out. After you’re done selecting a suitable cleaning product, transfer the solution to a spray bottle.
Scrub the drywall
Spray a little amount of the cleaning solution onto the part of the drywall with mold. Just a little amount will do as too much solution may drench the area, making it more difficult to scrub. To scrub the wall, you can use a heavy-duty sponge, a scrub brush, or an old toothbrush.
Scrub the affected area vigorously until the mold spots are no longer visible. Where the mold stain is too big, you can spray the solution and let it remain on the wall for a few minutes. This will help loosen the stain, making it easier to remove.
Dry out the cleaned area
Because the affected area will remain moist after cleaning, new mold may develop after a short time. It’s therefore important that you completely dry the area. To dry faster, use an electric fan.
Apply a Stain-Blocking Paint
Once the cleaned area is completely dry, it’s time to apply a stain-blocking paint. A stain-blocking paint will help prevent the mold stain from bleeding through wall paint. You can get a good quality stain-blocker from your local hardware store.
Vacuum the entire room with a HEPA vacuum
After scrubbing off mold from the drywall, it’s important to vacuum the rest of the wall and the floor. Doing this will eliminate any mold spores that have landed on surrounding wall and floor. Try to vacuum the areas as much as possible because any remaining mold spores pose a health risk to you and your family.
Knowing how to remove mold in your drywall can help keep you and your family safe from the allergic reactions and respiratory diseases caused by exposure. Don’t just let mold sit on your drywall. With the right techniques and cleaning products, you will be able to get rid of it in just a short time.
