Will Bleach And Vinegar Kill Black Mold On Concrete
Youve probably heard horror stories about black mold, an suspected silent killer that hides in water damage and ceiling tiles. If you find black mold in your home, you may be completely overwhelmed and not quite know what to do. Luckily, cleaning black mold is not as serious as you may think, and probably easier than you assumed.
Spores of mold find their way inside by holding on clothes, pet fur, and air currents into your home, but they wont grow unless they have plenty of water.
This is why you usually find mold in moist areas like a basement, part of a ceiling with a leak, or under your sink. To prevent mold from growing, you need to not only remove the mold substance, but the area of material of which you found it.
Will Bleach Or Vinegar Kill Mold On Concrete
Technically, yes. Bleach or vinegar can kill the mold organism. However, its not enough to kill it. It needs to be removed from your home. Just washing the area with a solution does not effectively do the right job.
The dead mold spores can still cause sicknesses, and while trying to clean the mold with solution, you can spread spores to other areas before they are killed, causing more colonies to form. Remediation by a Mold Busters professional team is the correct way to remove and kill mold in your home.
How Do You Polish Concrete Blocks
To polish concrete blocks, one popular option is to grind the blocks with a 150-grit metal-bonded diamond , apply a chemical hardener to densify the concrete, and then polish them with a 100- or 200-grit resin-bond diamond, or a combination of the two.
Alternatively, you can polish them with a 400-grit resin-bond diamond.
Whatever method you choose, use a diamond with the appropriate grits to achieve the desired results. If you want to add a bit of shine, a 100-grit diamond will work fine.
If you want to polish the concrete to a much higher level of finish, however, youll need to use a 200-grit or 400-grit diamond. Its also important to take time when working with the diamond, as overworking the concrete will dull the polish.

Mold Growth in Basement
This project is a perfect example of the compounding factors of poor ventilation and uninsulated concrete walls. The RH in the basement was 80%. This is very high. Mold will begin growing on random contents at this level.
80% RH is problematic even in well insulated walls. In a room with concrete walls, its guaranteed to cause mold growth.
The solution?
Increase ventilation by installing a constant flow exhaust fan in the bathroom. These units replace a regular bath fan, but operate 24/7 at a reduced speed. They provide continuous ventilation throughout the day.
Project Notes
- RH: 80% Temp: 56 deg F. CO2 = 545 ppm CO = 0 ppm
- 15-18 inches of standing water was present throughout basement.
- Virtually every surface was covered with mold growth.
- All appliances were submerged and required removal.
- Sump Pump was present but was not running due to the power being cut off to the home.
- No ventilation to basement has trapped humidity and has allowed mold growth to occur on all surfaces.
- Mold growth was observed behind all ceiling panels on car-decking subfloor and ceiling joists.
