What Is Mold And Why Do You Have It In Your Basement

Mold is everywhere around you, both indoors and outdoors. It is basically a fungus and can be white, green, orange, purple, and black. The fungus needs moisture to grow and a surface to spread on. Mold forms lightweight spores for reproduction that are continuously present in the air and arent harmful in small amounts.

When it has ideal growing conditions, mold reproduces extremely fast.

Drying a poor-ventilated basement is difficult, and mold can appear. In simple words, mold spores float in the air and need moisture to reproduce.

There are numerous reasons why your basement is wet, even if you dont have water damage or a leaking problem. The foundation walls might be wet because the water might penetrate the porous concrete walls.

Some people keep the dryer in the basement, which releases the humidity, or the air around the basement is humid, and it has access to the basement.

Whatever the reasons for mold are, you can control it and remove it, but it can be a daunting task. Making mold cleaning part of your regular household cleaning routine can help you sustain it.

Liquid Laundry Detergent And Household Bleach

TRYING TO REMOVE THE MOISTURE OUT OF THE CINDER BLOCK WALL

To clean mold off concrete, begin by cleaning the concrete surface with a hose, removing as much black mold as possible. If the concrete is located indoors, use a sponge to scrub away the mold. A scraper is also an effective tool for removing the mold from concrete.

Keep in mind that though these methods are effective, physically scrubbing or scraping the mold away will not remove the root, which is embedded inside the porous concrete. If the root is still intact, the mold will simply grow back.

Killing mold beneath the concretes surface requires cleaners that can penetrate the concrete. While bleach is effective and kills mold, its surface tension does not make it ideal for soaking concrete. Laundry detergent is a better option.

Create a cleaning solution by mixing a cup of laundry detergent with a gallon of water. Use a sponge or brush to apply the solution to the floor. The detergent will soak into the concretes pores, killing the black molds roots.

Use a scrub brush to ensure the solution penetrates the concrete and to remove the molds roots. When complete, rinse off the concrete with clean water. If outdoors, use a hose. If inside, use a mop.

Repeat this process if any mold is still present. Dry the concrete with a fan until it is completely dry.
