This 32-ounce trigger sprayer can easily cover up to 100 square feet at a time.

How does the formula work?

Now that we've reviewed the two main ConcrobiumMold Control products in the line, it's time to see how this works. You know that it does not contain toxic chemicals, so it kills the fungus and also inhibits its future reproduction.

The active ingredients (water, sodium carbonate, trisodium phosphate, and alkali metal carbonate) form a trisalt polymer that is strongly alkaline. Mold growth is known to thrive between 6.5 and 7.5 on the pH scale. They cannot survive in a high alkalinity environment.

Concrobium Mold Control helps you achieve a pH greater than 11, making it a powerful alkaline mold remover. Mold can remain dormant for a long time in an acidic environment, but it cannot survive in an alkaline state, which is why most antifungal medications contain alkaline foods.

When the formula is applied to existing mold growth, the molecules in the solution kill the mold spores by stripping them of moisture. This draining effect not only kills existing mold spores, but their colonies as well.

After the solution dries and remains on the affected area for several months, it forms a kind of alkaline shield to inhibit future growth. Once the mold spores have dried up, they can no longer multiply or grow back.

Concrobium Mold Control Benefits

  • This is an affordable, easy-to-use solution that kills existing mold and prevents it from growing on surfaces.
  • You can spray and forget because it leaves a barrier that prevents mold from reappearing. It also eliminates the musty smell.
  • This is an environmentally friendly, non-toxic solution that requires no dilution. Does not release harmful vapors.
  • Concrobium offers a wide variety of formulas that best suit different needs. It can be applied to both finished and unfinished surfaces.
  • You can safely use the formula in ULV (Ultra LowVolume) foggers. Use it before mold appears as a precautionary measure so you never have to deal with it.
  • You do not need any special protective equipment to use it. Just wear a pair of gloves, safety glasses, and an N-95 respirator or mask to protect against mold and mold spores.

Disadvantages of Concrobium Mold Control

  • In order to effectively prevent mold formation and its recurrence, Concrobium must remain in the affected area for a long time. If the surface becomes clean or wet, you must reapply the formula.
  • Concrobium prevents mold growth, but it only works on the surface and does not combat stubborn mold that can be deep-rooted in furniture.
  • Mold control does not help remove mycotoxins. It only affects the fungus.
  • Because the product does not contain bleach or bleach, it will not remove mildew stains from the surface. Because of this, many people consider this to be an imperfect or incomplete mold removal process.

Reasons to choose Concrobium Mold Control over traditional methods

As we don't know when homeowners have used a variety of natural and artificial cleaning products to remove mold. From laundry detergent to using powdered bleach to borax to essential oils, you'll find no shortage of DIY methods online.

While many of these traditional DIY methods and commercial products can remove mold to some degree, the effectiveness may be questionable. Many retail mold removal products are ineffective or hazardous to human and pet health.

Take bleach, for example, which is toxic and poses health risks to both the user and other household members, both during and after use. Also, bleach does not help prevent mold from reappearing.

The surface may appear clean when you've finished treating the area, but the mold will grow back in a few weeks. It is particularly ineffective for treating mold growth in porous areas like wood, drywall, and grout.
