How to Remove Mold From Painted Concrete

by HomeRepairExpert.com
Mold inside and around the home can be a problem. Mold growth is caused by excessive moisture from leaks, floods, humidifiers or improper ventilation. Before removing the mold you will need to identify where the excess moisture is coming from and fix the problem in order to the prevent future mold growth. Once this is done, you will need to remove the mold right away before the spores can contaminate other surfaces and cause health problems. Mold is toxic especially to people with allergies and other health conditions. Some of the signs of mold exposure are nasal and sinus congestion, eye irritation, respiratory problems, skin irritations and frequent headaches. Mold is not easily removed from very porous surfaces such as carpet and ceiling tiles, but other surfaces can be cleaned. With the proper tools and steps, you can remove mold from painted concrete rather easily.

  • Fan or dehumidifier
  • Water
  • Bucket
  • Chlorine bleach
  • Scrub brush
  • Gloves
  • Protective eyewear
  • Protective mask
  • Sponge
Dry the area where the mold is growing. You can use a dehumidifier or fan and open all windows and doors to allow for proper air flow and ventilation.

Protect yourself. Wear gloves to protect your hands. You may also want to wear protective eyewear and a breathing mask because you will be using bleach. Old clothes would also be a good idea, in case any bleach splashes on your clothing.

Mix one part chlorine bleach to four parts warm water in the bucket.

Dip the scrub brush into the bleach solution and scrub the area completely. Do not just do the area of visible mold growth. Scrub the entire surface because mold spores are invisible to the eye. Allow the bleach solution to stand for about 15 minutes.

Empty the bucket and rinse the scrub brush. Refill the bucket with warm water.

Wipe the area with warm water and a sponge to remove any excess bleach. Allow the area to dry completely.

Tips and Warnings

  • You may want to repaint the area with a mold resistant paint and sealant. This will discourage future mold growth. Be sure that the area is completely dry before repainting it.
