Next, you'll prime your piano a couple times over. Here's the supplies you'll need, which are part of the prepping process:
After using your tack cloth from the initial sanding, prime everywhere on the piano you want your color to be with Zinsser Primer, using a foam brush to get a smooth finish. This primer sticks to anything and covers great.
Dry, Sand, and Prime Again
Let the piano dry for the recommended time, then *sand all over with 150 grit sand paper. Tack cloth if off then prime and sand again. Priming a couple times makes it so you don't have to paint 8 coats of color. Repeat the process again if needed.
*If you don't want to sand between coats that's really ok, your end result will just be different than what these pictures show. The primer states you don't have to sand between coats, and you don't, but I sanded to get it extra smooth. The paint creates a little texture with each coat, and I also sanded because of reasons mentioned before. You don't have to take an hour to sand between coats. Just a quick sanding across the piano will suffice :)
