Hello all, I'm a newbie DIY'er when it comes to concrete/stucco work, so am looking for a few tips. Attached are three pics showing the repair needed so you can get an idea of what it is and the size. This is on a typical 1960's ranch house. The previous owner left various types of concrete/stucco repair stuff in the garage but I have no idea if any of it is the right thing to use. Do I just mix it up and trowel it in? It's a somewhat indented area where the exterior has deteriorated down there at the bottom of the wall. This is part of the exterior of a detached garage wall. I'm sure it's a pretty basic repair and would like to fix it before it erodes more .....trying to avoid hiring someone for a job that is probably a basic fix. Thanks again for the assistance!
