Make sure to protect the surface you are working on. Sand it down with sand paper if necessary. This mirror did not have any kind of varnish or paint on it so I didn't need to sand it down. Tape where you don't want to paint. But still be careful while you paint around that area. Paint can sometimes leak through.
Third coat. You can be the judge of how many coats of paint your project will need. Make sure each coat is fully dry before applying another one. And try not to apply more than 3 coats because the paint can start to look too thick and will start to clump.
The finished product. This was the perfect accessory for a blank wall that needed some color.
