EASIEST Way to Clean Moldy Concrete Patios, Driveways, Sidewalks // Pressure Washing Concrete

Based on your description, this does not sound like mold. On concrete, mold will appear in either a fuzzy format or a stain like appearance. It would not feel like a hard coating. In either scenario, it is fine to paint the concrete after youve thoroughly scrubbed and cleaned the area. Anything remaining is simply the pigment from the prior mold growth, which cannot regrow.

What Is The White Stuff Coming Out Of My Concrete

Efflorescence is a chalky white salt residue that can occur with any product containing cement. As moisture migrates up to the surface of the concrete, it carries along with it calcium salts from within the concrete. When the salts reach the surface, they react with CO2 in the air and form insoluble calcium carbonate.

The Mildew And Concrete Problem

Mildew is a type of mold which usually appears as a thin or fine dusting of a black, grey, or sometimes white growth. Mildew relies on three essential elements for growth moisture and food. Although your concrete is not a direct source of food, that unsightly mildew gets fed plenty of essential nutrients by the fine layer of dust that sits on the surface of your patio, path or walls. The same goes for the temperature requirements of mildew its happy to grow in any temperature you live in. And of course, concrete is also a major moisture magnet!

Outdoor mildew can grow on hard surfaces such as concrete patios or the floors of your basement. Not only can mildew ruin the appearance of your concrete and make the surface slick and slippery, it can also become a health hazard. Some people have allergies or sensitivities to mildew which can result in serious reactions, especially in people who have weak immune systems or respiratory conditions. For many reasons, if you have an issue with mildew, you want it gone, and quickly.

Is It Okay To Put Bleach On Concrete

Concrete is prone to dirt, stains, molds, and mildew. Yes, you can make use of the bleach to clean the affected concreted area in your home. Bleach will not only remove the stains and dirt from the concrete, but it will also deodorize and kill the mold and mildew if used properly. However, there are a few things you need to know first about cleaning the concrete with bleach.

The type of bleach to be used also matters. Pure household bleach followed by an adequate hot water rinse causes no harm to your concrete. Use chlorine bleach to kill the mold spores and remove the stains effectively. Oxygen-based bleach will only remove the stains but not kill the spores.

In case there are plants, furniture on the patio, or along with the steps, you need to remove or cover them as bleach will damage or discolor them.

After you have sprayed the vinegar solution on the area and allowed it to work its magic for a few minutes, you may need to use a deck brush or scrub brush to address stubborn areas.

    You will then want to rinse the area well with water.

      I Have A Major Moisture Issue Along One Wall In Basement Particularly Behind Furnace Duct

      Cleaning a driveway covered with mold and mildew

      The white, fluffy substance is efflorescence and the black spotting on the wall is mold growth. Efflorescence occurs when moisture moves through the concrete and deposits minerals/salts on the surface. In a basement, this can be a complex issue. First, I recommend looking at your downspouts and ensure they are moving the water far away from your home. Your goal is to reduce the moisture load in the soil near your home.

      If this doesnt solve the problem, youll likely need a sump pump and possibly an interior footing drain. While expensive, they are often the only way to completely solve the problem. In most cases this will involved removing the wall in the problem area so the footing drain can be installed at the very edge of the concrete slab.
