This before Pictures is not the real before. We have painted it for a while now. But Here is this years before picture. Before you start you want to pressure wash the patio and use outdoor paintable caulking to fill int the cracks. This picture shows you this step.
You will want a Paint Brush to use for cut-in around the edges.
You will also want a roller with an extension pole to roll on the paint. This makes the process MUCH faster. Make sure you get a ROUGH paint roller. They are extra cushy to get into all the nooks of the cement. My cement was pretty rough so I got an Extra Rough Paint Roller. (found at most hardware stores)
You will want to make sure you have a couple dry days in a row. First, cut in around the edges. Then, roll, roll, roll away. I did 2 thick coats to get the coverage I wanted it.
