How to Remove Mold from Painted Walls

Pre-Step: Remove the source of the moisture

Before you start, you have to remove the cause of the mold first. That is the source of the moisture that is causing the mold.

If it’s a leaky pipe, fix the plumbing issue. If there was a flood, check that your sump pump is working and that the area is thoroughly dry with a fan. If there are cracks in the window sills or foundation that is causing leaks, some of them can be easily sealed with silicone caulk.

It can also be caused by high humidity that is above the level of 55%. That will cause dampness and condensation. You will need a dehumidifier with a continuous drain to fix this issue.

1. Gather Equipment and Prep for Safety

First, you want to gather your cleaning tools and safety equipment.

Mold can trigger asthma and other allergic reactions in people who are sensitive to mold. For those people, it is best to avoid this activity.

Safety Equipment
For safety equipment, you want to have gloves, a dust mask rated N95, and safety glasses.

If you’re dealing with lots of mold, you will also want a Tyvex suit to protect the mold spores from getting on your clothes.

What You’ll Need To Clean Mold

You have several options when it comes to what to use to sanitize the mold.

Hydrogen peroxide or OxiClean will work for generic cleanups. Scrub with a scrub brush.

If you want a deep clean, you can use what the professionals use. RMR-86 is a no-scrub formula.

For small moldy areas, use the RMR-86 spray bottle format.

For large moldy areas, you can use the 2.5 gallon size with a garden pump sprayer or professional spray bottle.

2. Vacuum the Excess Mold

You’ve got a big mold problem that needs the excess mold vacuumed first.

With a HEPA vacuum, choose the wall brush and vacuum the excess mold. Only a HEPA-rated filter will be able to catch small size of mold spores.

3. Spray down the moldy walls

Next, with a cleaner of your choice, such as Oxiclean or RMR-86, spray down the moldy areas. Make sure it is generously wet.

In about 15 seconds, you can see the mold stains start to disappear.

If not, you can spray it again.

Some types of mold will require some light scrubbing.

4. Rinse with cloth and clean water

For indoor walls, use a cloth and clean water to rinse the clean from the walls.

5. Dry

Dry the surface thoroughly and wait 24 hours for it to dry completely.

You may use a fan in the room to help.

6. Optional: Run a HEPA Air Filter

To get rid of the mold spores present in the air of the room, run a HEPA air filter for 4-7 days. That will get rid of the remaining mold spores suspended in the air.

Method 2: How to Clean Mold from Walls with Borax

If you’ve got a small area of mold, you can clean it by scrubbing it with borax.

First, grab borax (sodium tetraborate), water, a spray bottle, and a scrubber.

These items will help you to remove the mold from your painted walls.

Combine the Ingredients

After you have gathered all the ingredients, now you will combine them to create a solution.

Mix 2 tablespoonfuls of borax with 2 cups of water. You have to be careful while mixing the ingredients together.

Wear gloves while mixing the solution.

Pour the Solution in a Spray Bottle

Now, as you are done with mixing the solution, pour it into the spray bottle you have.

Pouring it in the spray bottle will help you to apply the solution to the painted walls easily. Make sure you wear gloves while pouring it into the bottle.

Apply on the Moldy Painted Wall

Next, spray the solution to the infected walls.

Generously spray the entire moldy section and more.

Scrub the Wall

Now you need to scrub the wall gently. This will remove the mold from the wall.

After you are done with scrubbing, clean it with a cloth and water with a few drops of dish soap.

Spray a new layer and let it sit for 10 minutes.

Then clean it with a cloth and clean water.

This will help you to get rid of the mold and get your painted walls clean.

Optional: Run a HEPA Air Filter

To get rid of the mold spores present in the air of the room, run a HEPA air filter for 4-7 days. That will get rid of the remaining mold spores suspended in the air.

Takeaway

You can remove mold from the wall with this step-by-step guide.

However, if you are dealing with a larger moldy area, such as over 10 x 10 feet of mold, it is best to let the mold remediation specialists do it.
