Types of Wall
The technique for removing mold may be slightly different on the type of wall you have in your home. So, it is important that you not only know how to get rid of mold on walls but also know what type of walls you have in order to apply the best solution to the problem.
- Drywall is porous, that’s why mold loves to grow in this kind of material and you can only see the top layer. For this type, try a vinegar solution and avoid using bleach in order to get rid of mold on walls. Usually, if mold is too deep in the layers, it will keep coming back so the only solution is to replace your drywall. Fortunately, an alternative to traditional drywall is now available— mold-resistant drywall.
- Wallpaper is also commonplace for mold growth because water vapor can be trapped. The best solutions to get rid of mold on walls with wallpaper are white vinegar, baking soda, hydrogen peroxide, etc. Dip a sponge in a solution of your choice, and wring it out so as not to damage the drywall. Try to test first in an area that is not visible. Then gently rub in circles to get rid of mold and be sure not to soak the wallpaper.
- Cinder Block walls are not exempted to have molds. You need to clean the walls first using a liquid dish detergent and water or bleach solution. Then scrub using a brush to remove mold. For any mold residue, just wipe them away and apply some more solution. Let it sit for up to 20 minutes then dry the wall completely to prevent mold from recurring.
- Brick or concrete is also porous, so to kill the mold, you can use hydrogen peroxide or vinegar. Then scrub gently using a brush.
