Choose stucco or textured paint from a hardware or paint store. If you want, mix the stucco yourself. If you're doing a small job and only need to patch up stucco, consider getting pre-mixed stucco patch.
If you hope to cover up a lot of blemishes with the stucco finish, then you will need to buy a larger quantity of thick stucco paint. For a thick stucco coat, it will only cover approximately 25 square feet (2.3 square m) per gallon (3.8 l).  Ask the paint associate what they recommend for your particular job specifications. They may be able to recommend the best options for your stucco needs and help to supply you with the tools needed to complete the job, since stucco requires more tools than traditional painting. When purchasing stucco paint for outdoor surfaces, you can choose fine, medium or coarse sand stucco. Consult the paint specialists about which option would be best for your building. Stucco is usually made out of Portland cement, sand, hydrated lime, and water. Although some stucco recipes will differ, you can do pretty well by mixing up a simple ratio of 4:12:1 (cement to sand to lime), and then adding enough water, slowly, to get the stucco to the consistency of wet peanut butter. If you want to, add some mortar color to the mixed stucco to approximate the color of the surrounding stucco. This will make it easier to color the newly-patched stucco and blend it in to the existing stucco, although you want still need to color the whole wall later on if the colors don't match seamlessly. Pre-mix stucco patch can come in either textured or un-textured form, and comes ready to go, for ease of application. If you're only patching up a slight area and don't want to spend a lot of time mixing, this might be the right way to go.
