What Causes Mold on Drywall?
Mold on drywall is caused by excess moisture. This can be due to a leaky roof, plumbing issues, or high humidity. Mold spores thrive in damp environments and can quickly spread if not treated promptly.
Identify the Mold
Before treating mold on drywall, it’s important to identify the type of mold. Not all mold is toxic, but some can be harmful to your health. If you’re not sure what type of mold it is, it’s best to contact a professional.
Protect Yourself
When treating mold on drywall, it’s important to protect yourself. Wear gloves, a mask, and eye protection to prevent exposure to mold spores. Additionally, make sure the area is well-ventilated to prevent the spread of spores.
Remove the Mold
To remove mold on drywall, mix a solution of one part bleach to four parts water. Spray or apply the solution to the affected area and let it sit for 15 minutes. Scrub the area with a scrub brush and rinse with water. Repeat the process until the mold is gone.
Dry the Area
After removing the mold, it’s important to dry the area thoroughly. Use a fan or dehumidifier to dry the area completely. This will prevent the mold from coming back.
