Whats Wrong With Wet Drywall
Drywall is made out of gypsum and other additives. That makes for a relatively lightweight building material that is still pretty durable. At the same time, those components also absorb water. Soaked up water provides a perfect haven for mold to grow, and the paper backing of drywall contains cellulose which becomes food for the mold.
Preventing toxic black mold growth and the spread of mold spores is a major reason for removing sheetrock that has experienced water damage, but its not the only one. Drywall loses a majority of its structural integrity when it gets wet, which is especially dangerous on a ceiling.
Wet drywall also has to be removed from interior walls too though. Wall cavities simply do not dry unless the sheetrock is taken off and the cavity is aired out. Wet fiberglass insulation batts get heavy, and theyll start to slump down in the wall cavity creating large pockets of air loss at the top of the wall. This drives up both heating and AC bills.
Gather Your Drywall Mold Removal Equipment
When you remove mold, youll undoubtedly stir up spores and send them airborne. Wearing long sleeves and pants, as well as rubber gloves, a respirator mask, and a pair of safety glasses will help keep those spores from irritating you.

Why Can’t Moldy Drywall Be Cleaned
It is very difficult, usually impossible, to adequately remove mold from porous materials, and that includes drywall. Why? Well, porous materials aren’t entirely solid, even if they appear solid to the naked eye. Materials like drywall have very tiny holes, or pores, in them, much like the pores in your skin. Microscopic mold spores can remain unseen in the pores of the drywall, even when the drywall appears free of mold. It’s similar to the way dirt or oil can be trapped in the pores of your skin, even if you don’t see it.
Much like how dirt or oil trapped unseen in the pores of your skin can lead to acne or other skin problems, unseen mold trapped in the pores of drywall can grow and spread and can also cause health problems. Since there is no effective way to remove mold from the pores of the drywall, the affected drywall must be removed and replaced.
Does Vinegar Kill Mildew And Mold
Vinegar has antifungal and antibacterial properties, and it can be a cheap and effective treatment for many types of mold.
Household white vinegar typically contains about 5 to 8 percent acetic acid. Acetic acid is a moderately strong acid with a pH of around that can disrupt the growth of a wide range of fungi and other microorganisms.
Research has found that vinegar is effective at preventing mold growth on fruit and at removing some , but it isnt effective at killing every type of mold.
In a 2015 study , researchers found that vinegar made out of 4- to 4.2-percent vinegar acetic acid was effective at treating Penicillium chrysogenum but not Aspergillus fumigatus. Both are common household molds.
If you find vinegar doesnt help you get rid of the mold in your house, you can try one of the other cleaners well look at in this article or call a professional.
The Environmental Protection Agency recommends getting a professional cleaner if the covered area is larger than 10 square feet or roughly a 3-foot by 3-foot square.
You can safely use vinegar on a wide range of surfaces, but well look at some specific surfaces on which you should avoid using vinegar.

How To Clean Mold From Wood
Mold loves wooden surfaces. Whether its your window sills, flooring, wall framing, or furniture, the high cellulose content of wood provides mold with lots of food. Because wood is also very absorbent, its easy to create a perfect environment for mold with very little moisture. If you do find mold growing on wood in your house, heres how to get rid of it.
Youll need:
100-grit sandpaper
Method:
Step 1: Begin by vacuuming up as much of the mold as possible using a vacuum with a HEPA filter. You can also use a soft-bristled brush to dislodge the mold and make this easier. Remember to wear a dust mask to prevent breathing in mold spores while you do this.
Step 2: Add a teaspoon of soap to two cups of water in a spray bottle. Shake to combine and spray the mold and surrounding surface.
Step 3: Use a soft-bristled brush to scrub away the mold and mildew. Use paper towels to soak up any excess water.
Step 4: To kill the roots, add 1 tablespoon of borax to a cup of water and use a soft-bristled brush to apply the solution to the area. Allow it to absorb into the wood.
Step 5: Run a fan or dehumidifier in the room to quickly dry the wood.
Step 6: If the mold is very stubborn, use 100-grit sandpaper to remove the affected area.
Pro Tip: Is the wood still stained? This is usually a result of mildew the discoloration mold leaves behind. While bleach doesnt kill mildew, it can help remove the stains. Try scrubbing a small area with a dilute bleach solution.

How Do I Remove Mold On Sheetrock
Removing mold on sheetrock that has been previously primed or painted is a relatively simple procedure. Before you begin, locate the source of the moisture causing the mold and remove it to prevent future mold growth. To remove the existing mold on sheetrock, you will need to mix a solution of one part chlorine bleach to four parts of water. After donning protective gear as necessary, apply the solution to the sheetrock using a sponge or spray bottle. After the mold has been removed, rinse and dry the surface well and apply a stain blocking primer or sealer before repainting the surface.
Before removing mold on sheetrock, you should inspect the surrounding area to determine the cause of the mold. Any leaks in the roof or plumbing should be repaired to prevent the mold from reoccurring. If the mold is being caused by condensation, you may need to install a dehumidifier in the room. If the sheetrock has been saturated or damaged by water, it will probably need to be replaced. Extremely large areas of mold on sheetrock may need to be disposed of by a professional to prevent the spores from spreading onto carpets, draperies, furniture, or ductwork.
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.
