Mold spreads from one block to another. It would be best if you seal the affected floorings of a room. As a result, mold can’t develop from the affected to the cleaned space.

Regarding this, seal every exit way like the door by hanging plastics to stop the spreading of mold. We suggest you keep the window open for ventilation.

Running a fan will be another effective way to keep the room moisture-free.

The last but effective method to control the spreading of mold is to vacuum the area once you treat the affected space. Vacuuming the surface will eradicate the inactive spore. In this case, it would be best if you use a HEPA filter to suck away the spore efficiently.

Besides, you can also keep the area you treated with solution dry by vacuuming. If there is still moisture or wet situation on the treated space, mold will return.

At the last stage, we recommend you use a dehumidifier to dry the last drop of moisture.
