What is the best way to clean stucco?
For general cleaning, use water first. A very soft brush is best for hand washing. You can also clean the surface with a light pressure spray wash using water only. If you find this is not cleaning the surface adequately, you may needs to use a cleaning agent. Try to find a detergent that is friendly to the environment. If you use a detergent, be sure to rinse the surface well after cleaning. If, after cleaning, you find the surface seems chalky or powdery, you might want to consider a coating of masonry surface conditioner. This will give the surface some protection from further crumbling and will protect the finished paint job from chipping and loosening in the future. This also stops the stucco itself from soaking up your paint as it is applied. www.essortment.
