Removing Mold From Walls
Removing mold from walls is sometimes a fairly simple job and sometimes a very complicated, difficult job. The ease or difficulty of dealing with mold on walls varies depending largely on whether it’s a non-porous wall, like a concrete wall or a tile-covered wall, or a porous wall, like a wall made of wood or drywall. The proper techniques for removing mold from walls vary greatly based on the materials from which the wall is made. It’s also important to understand that when there is mold on walls, there is often, though not always, mold inside the walls as well, and that must be handled with additional measures.
Non-Porous Walls (Concrete, Tiled Walls, Etc.)
Removing mold from walls that are non-porous, like walls made of concrete or those that are covered with tiles, is easier than removing mold from other kinds of walls. Use an ammonia-free soap to scrub away the mold. Follow that with a biocide designed to kill mold, available from many home improvement stores.
Removing mold from walls that are non-porous is pretty straightforward, although it should be noted that the Environmental Protection Agency recommends seeking professional assistance if mold on walls covers an area greater than ten square feet. It should also be noted that if mold is found on non-porous walls, mold may also be growing in other areas of the home, including inside walls and inside heating and air conditioning ducts, so a thorough inspection should be made of the home.
Porous Walls (Wood, Drywall, Etc.)
Removing mold on walls made from porous materials, such as wood, drywall (also called sheetrock or plasterboard) and the like, is much more difficult. Often, mold cannot be completely removed because it has become integrated into the materials. It’s not just on the surface of the wall. In such cases, the moldy materials must be removed altogether and replaced. Removing moldy materials must be done very carefully because mold spores are easily disbursed into the air where they can be inhaled, leading to numerous health problems. Drifting mold spores can also land on other surfaces, where mold can then grow and spread.
Mold Inside Walls
In addition to mold on walls, you may have mold inside walls. Mold sometimes grows in the insulation inside walls, in which case the insulation must be removed and replaced. Mold sometimes also grows on the wooden studs or supports inside walls. In this case, it will generally need to be removed by sanding the wood and/or encapsulated by painting over it with a special sealant that will prevent the mold from growing or spreading. Because both sanding and encapsulation techniques are difficult to perform properly, it is advisable to call in a professional for those tasks. Performed improperly, these procedures can contribute to the spread of mold and pose serious health risks.
Safety Measures for Removing Mold from Walls
When you handle mold, whether you’re scrubbing it with soap, removing moldy materials like insulation or dry wall, or sanding moldy wood, you disturb the mold and tiny mold spores are dislodged and drift about in the air. These spores are easily inhaled and can lead to serious health problems, including severe respiratory disorders. To reduce the risk, you should wear an N-95 respirator mask, disposable gloves, disposable shoe covers and a disposable hair covering while handling mold. Additional safety measures are required when removing moldy materials like insulation or dry wall and when sanding moldy wood.
