Dealing With Mold On Drywall
As we just said, since mold cannot be completely removed from drywall, the drywall must be removed and replaced. This must be done with care because cutting into moldy drywall causes mold spores to become airborne and spread.
The U.S. Environmental Protection Agency advises that if mold covers more than 10 square feet, a professional remediation company should be hired to remove the mold. If it is a smaller job that you plan to handle yourself and you have any health concerns, speak with your doctor to make sure it is safe for you.
First the work area must be prepared. Furniture and other items should be removed from the area if possible. Otherwise, they should be covered securely with sheets of heavy plastic to protect them from mold spores.
Plastic sheets should be taped over heating and air conditioning vents to prevent mold spores from entering your heating, ventilation and air conditioning system. Hi-hats hould also be covered with plastic.
The floor should also be covered with large sheets of plastic, to prevent the flooring from becoming contaminated with mold.
First the drywall should be sprayed with water to prevent mold spores from becoming airborne as the drywall is taken down. The moldy pieces of drywall should be enclosed in heavy plastic trash bags before you carry them through the house, so as to prevent scattering mold spores as you go.

- Step 2: Next, use a hepa vacuum on the surface of the drywall to contain spores, mycelium and mycotoxins.
- Step 3: After this, use the glove box removal method, which requires you to cut a box of plastic thats four inches longer and wider than the affected area.
- Step 4: Use spray adhesive to apply the plastic box over the moldy drywall. This keeps the mold from entering the air when you begin to cut the drywall.

Does Vinegar Kill Mold On Drywall
Vinegar is effective for killing most mold that grows on drywall. Drywall is porous, which limits the effectiveness of surface disinfectants, such as chlorine bleach. One or more applications of vinegar kills most mold. Mold that is growing behind walls or in insulation requires tearing out and replacing these materials.
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.

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.
