Stucco is great stuff, but it can be a pain to get the repair stucco to match the original. In fact, if the you have a lot of patches, you may have to throw in the trowel and cover it with a cement-based paint or an acrylic exterior paint. Before you paint, don't forget to let the stucco patches cure at least 30 days. Also, when it is time to paint, dampen the wall with water. Finally, be aware that to prevent blotches cement-based paint will need a primer coat. Acrylic paint won't.
