Mould Growing On Concrete Floor

Here s what is happening water on the surface of the concrete gets absorbed into the concrete.

Mould growing on concrete floor.

Mold on concrete is something you probably don t expect to see. The last measure is to add trisodium phosphate to your bleach mixture. Fill a bucket with clean water. Concrete itself does not promote the growth of fungi.

Otherwise it will spread and be difficult to remove. Efflorescence occurs when water moves through a masonry structure bringing unbounded salts to the surface. Mold growth on a concrete wall due to excess humidity. If you see mold start to take hold of your concrete surfaces whether on a basement wall or patio you need to get rid of it immediately.

Removing mold from a slightly damp floor will reduce the amount of mold spores released into the air during removal. On it s own concrete does not provide a sufficient food source for fungal growth. Allow it to sit and then rinse again. Begin to mop up the area of affected concrete.

Moisten the concrete floor with water prior to mold removal. It crops up when moisture from a leaking pipe humidity or condensation interacts with organic material on the concrete such as carpet padding drywall or paper. Use a heavy duty sponge or scrub brush to apply your chosen cleaning solution to all visible moldy areas on the concrete. This white fuzz you are referring to is called efflorescence.

Mold can grow on concrete as long as there is moisture on it. So put first things first. Use a spray bottle filled with water to lightly mist the moldy concrete. As the water dries it escapes back up through the concrete s pore structure as vapor carrying with it minerals and salts from the concrete.

Dust and debris that accumulate on concrete surfaces become sources of food for mold thus facilitating their growth. Scrub the areas vigorously. White mold growth provides an additional challenge because it is often confused with efflorescence a crystalline growth structure found on concrete and masonry surfaces. In time this elevated surface moisture creates an environment conducive to mold growth.

Don t use a wire brush which can scratch concrete. Once the area dries you can visibly see how much mold is left on the concrete if any. If you re using mold killing detergent apply it directly to the spots and scrub it with a bristle brush. You can prevent mold growth on concrete surfaces by ensuring that they are clean and preventing moisture from accumulating on them.

Clean up the area and then fix the water problem so the mold doesn t return. Mold growth on concrete due to humidity is typically diffuse and spread across a large area. Concrete floors with their bumpy and porous texture is a great place for mold to thrive. Although concrete does not have sufficient food to support mold growth it will thrive when there is adequate moisture.
