How to Properly Get Rid of Stains on Your Stucco Siding

Aug 10, 2015

If you’ve got beautiful stucco siding in Kansas City, then you’ll want to make sure that it remains beautiful. This means cleaning it on a semi-regular basis and making sure that you take care of any stains that might occur. The last thing you want is dirty or stained stucco siding as this will end up hurting your home’s curb appeal. So let’s go over how you can remove stains from  your home’s stucco siding:

One of the biggest mistakes a homeowner can make is to simply paint over the stain. This is a mistake because stucco has never been painted in the first place. The fact that it has never been painted is one of the reasons why it’s so easy to maintain – but once you paint it, it’s going to require periodic work in order to maintain it.

If the stains are dark and black in appearance, then there’s a chance that they are being caused by mold, mildew or algae. This can happen if there are any trees or bushes that are located close to your stucco walls. You should be able to clean the black stains out using oxygen bleach solution. Make sure that you avoid using chlorine bleach since this will end up killing the bushes and trees nearby due to its toxicity. Oxygen bleach is simply a powder that you mix with water. Clean the stains out using oxygen bleach on an overcast day. Another option is to use copper, which is a natural biocide. However, it requires that you attach small copper strips to the top parts of your walls.
