How Do You Kill Black Mold On Drywall

How To Remove Mold From Tile And Grout Walls

How to remove and kill mold – Bleach vs vinegar
  • Use a stiff scrub brush and a household cleaner to thoroughly scrub the mold off of the tiles and grout.
  • If there are still stains on the grout after cleaning, you can use bleach or hydrogen peroxide to fade the stains. Apply the bleach or peroxide to the grout and let it sit for about 10 minutes.
  • Another way to clean both the tile and the grout is with baking soda. Mix the baking soda with water to make a paste, use a cloth to spread the paste and the tile and a toothbrush to scrub on the grout.
  • Regardless of which cleaning solution you choose, make sure to thoroughly rinse the tile and grout with water and dry completely.
  • Apply a grout sealer to reduce the risk of future growth.

What Causes Mold To Grow

Black mold, like most molds, thrive in conditions that are dark, unventilated and damp. The less the spores are disturbed the more they will grow it can grow for months, even years behind a surface without being noticed. It may have started out in an area, such as behind or underneath appliance, anywhere there are pipes, especially leaking or sweaty pipes and/or around leaky windows. It can also seep in from the ground around your home. High humidity can also cause excess moisture which can develop into spores. Once it has started to grow it can spread on and into the walls.

Tackling The Underlying Cause Of Mold

Molds are all around us we breathe in their spores every day. Its impossible to prevent mold from entering any property, but steps can be taken to stop mold from finding a new home in your house. Without addressing the underlying cause of why mold is growing in a particular area, it will just keep coming back.

Molds only need two things, food and damp. Its impossible to remove the food mold needs from your home, because your property is made of it. Particle board, gypsum, wooden framing, and soft furnishings can all nourish and sustain large mold colonies. What you can control, however, is damp. When mold is discovered, look for the underlying source of water.

There are three common ways that water can cause problem mold growths:

  • Maintenance issues such as leaking pipes or failed window seals
  • Human error, for example not drying water in shower door tracks or splashing water around a sink
  • Construction-related, usually relating to ongoing condensation issues caused by poor airflow

The first two are easy to resolve. Simply repair the problem or change your habits to be more conscious of where water is splashing and pooling. If mold is growing because of the construction of your property, it may require more extensive intervention. Installing fans or vents, replacing portable heaters, or investing in a dehumidifier might be necessary to resolve the problem.

How To Get Rid Of Mold In Attics

Attics are prone to mold either because of leaks from roofs or window seals, or because poor ventilation is allowing condensation to build up. Therefore treating those problems is always the most important step you can take to avoid getting mold in your attic, or to prevent it from coming back. Once youre sure your attic is watertight and ventilated, discard any stored items that are contaminated, or remove them for cleaning and restoration. Seal off the attic during cleaning and use a wet vacuum to clean as much visible mold as possible. Treat walls, floor, and exposed timbers with a mold removal spray to kill mold quickly and effectively, and install a fan or dehumidifier to dry the attic once the treatment is complete.

Removing Mold From Different Surfaces

How To Kill Mold on Drywall

Once the root cause of the mold has been dealt with, its time to address the visible mold itself. Often the infestation is worse than can be seen with the naked eye, so its important to do more than wipe mold off surfaces and hope for the best. The mold you see is the spores or fruiting body of the fungus, but often the hidden roots survive a first attempt at removal and the mold comes back. Heres how to remove mold for good, wherever you find it in your property.

Before you start: Make sure to ventilate the work area properly, and wear appropriate personal protective equipment to protect against mold spores that will be disturbed when you begin working. Gloves, safety glasses, and an N95 or better mask are all essential. Wear a long sleeved shirt and pants to avoid getting spores on your skin. Try to close off the area from other rooms to prevent spores from spreading throughout your home, and consider renting a HEPA air filter.

Pro Tip: The EPA recommends only removing mold yourself if it covers an area less than 10 square feet. Any larger than that and you need to call in the pros.

    • Spray the affected area and scrub until the spots are gone.

    Is Vinegar More Effective Than Bleach At Killing Mold

    Vinegar truly is better than bleach at killing mold. The EPA does not recommend using bleach to kill or remove mold, except in special circumstances. In most cases, a background level of mold spores will remain after the application of bleach.

    Bleach only kills surface mold, not the membrane underneath, according to ServiceMaster. That means the mold will grow back. In fact, recognizing the bleach as a threat, the mold will grow back even stronger. When bleach is used on porous surfaces like drywall or wood, mold membranes will move deeper into the surface to avoid the chemical.
