How To Clean Mold Off Walls
Mold on your walls not only smells and looks bad; it can be a health hazard, too. We’ll look at some ways to wash mold from any type of wall, and hopefully stop it from returning.
Before cleaning mold, you need to be sure the underlying cause of the mold is repaired. Fix leaks, make sure your home is properly ventilated, and install proper insulation to prevent condensation. If you don’t fix the cause of the mold, it will keep returning.
Also, you need to be careful when cleaning mold. Some molds can be harmful to humans if inhaled. Wear proper protective masks and eye wear so you don’t make yourself sick.
When using chemicals like bleach, be sure to wear protective gloves to prevent injury to your hands.
Removing Mold from Concrete Walls
After removing anything that is hanging on the walls, you can get to work scrubbing. For concrete walls, bleach and elbow grease are the most effective ways to get rid of mold. You can make a good mold-cleaning solution by mixing one part bleach with three parts water. Take a heavy-duty scrub brush and scrub until all mold spots have disappeared. You may find it helpful to let the bleach sit on the wall for a few minutes before you begin washing. If the mold is resistant to scouring, you may want to use a commercial mold remover, along with your bleach and water solution.
After scrubbing, dry your walls with a towel. You may also consider using a waterproof sealant on your concrete walls, then priming and painting them, to help prevent future mold growth.
How To Clean Mold Off Painted Walls
Mold is common in kitchens and bathrooms, because of the moisture and humidity present in them. Mold can also grow on interior walls due to leaks from the exterior of your home. If this is case, you must remove and replace any affected drywall first, or you will never get rid of the mold.
If there is no drywall damage, you can begin the process of cleaning the mold from the painted walls. Before you begin, be sure to protect your flooring from spills by using drop cloths or old towels.
You can use the same mixture to clean painted, interior walls as you used to clean concrete ones. Mix one part bleach to three parts water and use it to clean your walls. Instead of using a heavy-duty brush, you will want to use a sponge or rag for cleaning painted walls.
After you’ve cleaned away the mold spots, there will probably be some stains left from your scrubbing. You will need to repaint these walls to get them looking right again. Be sure you prime and seal the walls before painting, and use the correct type of paint for the room you are painting.
