What Causes Mold Or Mildew Inside The House

Can You Paint Over Mold?

Mildew can show up in rooms with high levels of humidity such as bathrooms, kitchens or basements and can appear as black, gray, green or brown spots. Areas in the home with high levels of humidity that are without proper or adequate fresh air circulation can eventually create mold or mildew problems.

To prevent mildew buildup ensure you create good air circulation within the home by installing bathroom vents that lead to the outdoors, replace air filters on furnaces and/or air conditioners at recommended intervals, open windows even slightly to allow some fresh air to circulate through the room. You should also make sure the proper ventilation is set up for any washers and dryers in any basement or laundry room.

Mold is typically caused by water leaks where the water infiltrates the drywall materials of the ceiling or walls and is left to sit and soak into the drywall for a long period of time.

Leaks are usually caused from leaks from a bathtub, a toilet, a water faucet or sink, a leaking roof or from flood damage. It is imperative to find the source of the water damage causing the mold and fixing it before it wreaks havoc on your home and your health.

Paint itself is not a cause of mold or mildew but the appearance of bubbling paint, peeling or cracking paint are usually signs that high levels of moisture are present and that immediate action should be taken.

Tip 5 Use A Mold Spray

Ceiling mold thats caused by bathroom humidity is easier to deal with. Its mostly at the edges and covers a small space. But if the mold was triggered by a leak, the damage is probably on both sides of the ceiling. Meaning theres probably more unseen damage on the upper side of the ceiling cavity. You may have to remove and replace all your ceiling panels.

If its a mild case of bathroom ceiling mold, you can use home remedies like borax, tea tree oil, baking soda, vinegar, ammonia, bleach, or hydrogen peroxide. Ordinarily, spraying a concoction on the mold will kill it off. After spraying, scrub the sprayed area with a scouring pad and re-spray. Many mold sprays are toxic, so ensure the bathroom is well ventilated before you begin.

Mixing certain cleaning materials can be toxic e.g. ammonia and bleach. Plus, while ammonia and bleach are effective, they can damage the ceiling itself, so try something milder first. 2 cups of hot water mixed with ¼ cup of vinegar and 2 tablespoons of borax is a good option. Scrape off any surface paint before spraying your anti-mold mix. Let it dry naturally and dont rinse it off.

Kill And Clean The Mold

The first step is to kill the mold and clean the surface.

This is most commonly done by washing the area with bleach and water mixture.

Mix 3 parts water to 1 part bleach. The bleach mixture will kill the surface mold and help remove the stain color from your walls.

Make sure to wear a respirator and rubber gloves when using bleach as the fumes are toxic and bad for your skin.

Rinse the area with a wet rag to remove the bleach and allow the area to dry 100%. A fan and/or dehumidifier will help significantly.

  • In a spray bottle, fill in some clean water and spray gently on the black mold located on the painted walls. It will enforce the spores on wall preventing them from floating through the air and spreading.
  • In a bucket, pour a gallon of clean, hot water, half a cup of bleach and a third cup of laundry detergent. Mix the solution properly and immerse a clean sponge. Having some protective gloves on, during the cleaning process is essential.
  • Immerse the clean sponge in the bucket, squeeze a little and wipe off the black mold from the surface vertically. Repeat the process until there is no fungi on the walls surface.

  • Using a dry towel, you will dry the walls and move the fan closer to the wall to keep it dry. It should take at least two days.
  • Coat The Stained Area With Primer

    Once the mold is gone, it would be best to coat the stained area with a paint primer. Coating the area where the mold used to be will help the paint stick better.

    A coat of primer can also help prevent the mold stains from showing through the fresh coat of paint. Without it, you will need to use multiple coats of paint before you can get the same results.

    Apply a coat of primer onto the stained ceiling and let it dry out. It would help if you applied one to two more coats of primer afterward to properly seal the stains away.

    S On How To Paint A Moldy Bathroom Ceiling

    Painting over mold without killing it and treating the area first is a horrible idea. If you paint over mold, the fungi stay alive, chip the paint, and eventually show up again.

    With that said, here is a list of steps you should follow so that you can paint over the moldy area and prevent the fungus from coming back.

    S To Remove Black Mold On Painted Surfaces:

    How To Apply Zinsser Mold Killing Primer

    Step 1. Despite moisture being the initial problem, it is important to lightly dampen the area prior to removal. This should prevent many of the spores from becoming airborne. A respirator and other protective gear must still be worn.

    Step 2. If there are other surfaces such as carpeting that might be discolored by bleach, these surfaces should be covered with towels or plastic sheets, which can be obtained inexpensively at most home improvement stores.

    Step 3. In a sturdy container mix 1 gallon of water with bleach. For areas with slight mold, use 1/2 cup and for areas that are heavily covered in mold, mix up to 1 1/2 cups of bleach. To prevent ill effects from its fumes, make sure that the room is properly ventilated.

    Step 4. Saturate a regular household cleaning sponge with the bleach solution and thoroughly cover the affected area. If the sponge is too stiff, the paint may be damaged, so it is more important to make sure that the area is saturated than it is to roughly scrub the area.

    Step 5. Allow the solution to remain on the affected area for at least 15 minutes.

    Step 6. Use a mixture of dish detergent and fresh water to clean the area thoroughly, but do not soak the wall with water. The wall should appear clean. This step should remove the traces of mold and the bleach solution. If the cleaning mixture is not properly washed off the painted wall, the wall will very likely become discolored.

    What Is The Best Bathroom Paint To Use

    The best type of paint for bathrooms is a satin, semi-gloss, or glossy finish with a mildew-resistant additive. Ideally, your chosen paint should last a while. However, if you’re set on a flat or matte finish, there are options for you too. Don’t forget to clean and prime walls before painting for the best results.

    Tip 4 Verify Leaks Vs Nails

    When you notice a yellowish-brown patch on your bathroom ceiling, youll assume its a leaking roof. It may not be. If your bathroom roof has nails or rivets, these bits of metal encourage condensation. This is expected because metal is a good heat conductor. But if this condensed liquid consistently drips onto the same spot on your bathroom ceiling, it may seem like a leak.

    Visual inspection is the only way to be sure. Your roof plumber has to access the ceiling and confirm whether its a leaking pipe or merely a dripping metal fastener. The latter is easier to resolve because you can replace the dripping item or insulate it in some way to reduce damage. Use a moisture meter or a touch-test to see whether the whole ceiling is moist or just the nails.
