Mildew is a type of fungus that grows in moist and humid environments. It appears as discolored growth on surfaces and is often accompanied by a musty smell. Mildew can grow on various surfaces inside and outside the house, including walls, ceilings, bathrooms and basements. If left unchecked, mildew can cause discoloration, damage to surfaces, and even health problems. It’s important to regularly inspect your home for signs of mildew. In this article, we will look at how to deal mildew and painting as well as the steps to remove it.
Bathrooms are often the dampest and most humid areas of the home, making them ideal environments for mildew to grow. Look for discolored growth on walls, ceilings, and around sinks, toilets, and shower stalls. Ventilate your bathroom after use by opening windows or turning on a fan, and clean regularly to prevent mildew from growing. Basements are often damp, dark, and poorly ventilated, making them breeding grounds for mildew to grow. Kitchens are often humid due to cooking and dishwashing, making them another common area for mildew to grow. Look for tiny spots on walls around sink areas, and be sure to routinely clean around them. The biggest step in prevention is to keep these three areas ventilated.
Gutters are the most common mildew attracting points because thy carry water every rainfall. Look for green, discolored spots on the fascia and trim as this will show mildew from the gutters. Mildew will only cover wall areas that are closest to points of moisture. Look for outdoor water outlets, sinks, and the corners of the house where gutters converge. Wall spaces behind AC units collect mildew as well as the areas behind shrubbery that do not receive direct sunlight.
For interior surfaces, start by mixing a solution of equal parts water and white vinegar or water and bleach. Then, use a sponge or cloth to apply the solution to the affected area and let it sit for 10-15 minutes. After the designated time, rinse the surface thoroughly with water and let it air dry. If the mildew is stubborn and doesn’t come off easily, you can use a scrub brush to help remove it. Or you can use RMR 141, which uses ammonium as its active ingredient to kill microorganisms and eliminate mold.
For exterior surfaces, pressure washing is the best method for removing mildew. Before starting, make sure to clear the area of any loose debris and protect surrounding plants and landscaping. Mix a cleaning solution of water and a mildew-removing cleaner. Connect the cleaning solution to the pressure washer and start with a low pressure setting, gradually increasing the pressure as needed. Make sure to keep the nozzle at least 18 inches away from the surface to avoid damage. After pressure washing, rinse the surface thoroughly with water and let it air dry.
What paint should I use?
The paint you choose depends entirely on the surface you are working with. Remember to never simply paint over a mildew damaged area because the growth will eventually eat thru the paint. That is why a good prep job is important because it kills the mildew and creates a clean surface for the paint to adhere to. Another tip is to avoid using alkyd and oil based paint as this will only feed the mildew with its organic substances. If you are color theming your interior, here is a guide that will help with that.
