Choosing to use stucco siding in Kansas City is typically a good decision. Stucco is plaster-based and coarse, which means that it’s incredibly hard and just slightly porous. This makes it a material that is naturally mold-resistant. However, because it’s not completely nonporous, mold can still grow on the surface if the conditions are right. The following are a few tips to help you keep mold from growing on your stucco siding:

Mold can basically grow anywhere where there is “food” to feed on. Mold feeds on organic materials, which means that it can even feed on dirt. Ideal growth conditions for mold are humid atmospheres, so it can be a real problem in summer.

The best way to prevent mold from growing on your stucco walls is to keep them clean. If you notice that dirt or mud has begun to collect on the stucco, you’ll need to wash it off. Dirt and mud contain nutrients that mold requires in order to grow. If the weather has been highly humid for long periods of time, consider using a dehumidifier or a heater to dry the stucco to prevent the moisture that collects from attracting mold. You should also consider using a mildewcide paint to help add an extra layer of protection against mold.

If you do spot mold growth on your stucco walls, then you can use diluted bleach in order to kill it. Create a solution that consists of five parts water and one part bleach and spray it over the moldy areas. Make sure that you use gloves and that you then scrub the affected areas with a sponge before rinsing.
