    Can You Paint Over Mold

    In general, paint does not bond well to surfaces that have mold or mildew on them. In time, as the surface continues to be wet and then dry over and over again, the paint will chip off. It is possible to paint over a surface with mold on it but if you have a large area of mold/mildew you are better off removing the material instead of spending time painting over it.

    It takes a lot more steps and work to remove mold or mildew versus covering up with paint, but your walls will look nice and new again! Mold and mildew enjoy the same conditions that promote paint failure, so get rid of it! In addition to following standard painting procedures, be sure to have a thorough cleaning before painting over a moldy surface. You want to make sure you get rid of all the mold and mildew, or else the paint will eventually flake off. Start by washing down affected areas with a household cleaner like TSP or even vinegar and water, then let the area dry completely.

    Mold and mildew can be very dangerous to humans, especially those who have allergies or compromised immune systems, so its important to take precautions when getting rid of these allergens. In fact, you might want to call a professional mold removal service but make sure they use EPA-registered biocides to keep your family safe!

    Where In Homes Is White Mold Most Prevalent

    Mold tends to thrive in dark, damp environments with a food source present.


    Attics provide an ideal environment for white mold since they contain plenty of food sources such as wood and insulation. Leaky roofs, condensation from fluctuating temperatures, leaky pipes, and/or poor ventilation can provide mold with the moisture it needs to grow. Eliminating mold from attics can be particularly tricky due to the tight spaces. We recommend checking your attic occasionally for the appearance of white mold or a musty smell.


    White mold in basements frequently grows on concrete walls, wooden floor joists and possessions stored there such as clothing. Water often seeps through basement walls to create a moist environment that is beneficial to mold growth. Cold outside air that comes in contact with warm indoor air in basements can also cause condensation making it a perfect breeding ground for white mold.

    Its easy to confuse white mold in a basement with a substance known as crystalline efflorescence. Both substances grow in high humidity areas, but efflorescence isnt a type of mold. Efflorescence is a salt deposit left behind when moisture makes its way through concrete. In order to tell if it is white mold or efflorescence mist the affected area with water. If its efflorescence the salt with dissolve away. If youre still unsure, you should have mold testing performed, because mold can spread inside the walls and floor joists.

    How To Differentiate Between White Mold And Efflorescence

    White mold and efflorescence look a lot alike. In fact, theyre so similar that people often mistake one for the other. Both are white in colour and found on walls and other building materials. Understanding what both substances are and how they form will help you to determine which one is making an appearance in your home.

    So what is efflorescence? Simply put, efflorescence is salt deposits commonly found on concrete and brick. It develops when water evaporates from concrete or brick, and leaves behind a salty residue on the surface of the material. However, efflorescence causes only cosmetic damage and will not threaten the structural safety of your home. Likewise it also doesnt pose any risk to your health.

    Tips for distinguishing between white mold and efflorescence:

    • Efflorescence dissolves in watermold does not

    How To Identify White Mold On Walls

    Detecting Mould in Your Attic or Crawl Space

    If youre not sure if its mold or damage, try this test. At a place where the white stuff isnt too noticeable, dampen a cotton swab with water and rub it gently into the area. If theres mold, it will turn dark brown or green on the swab. If its damaged, there wont be any discoloration.If youre still not sure, there are ways to test for mold at home without having to pay for costly lab analysis.
