Start by lightly hand sanding the laminate. You only want to rough up the finish a bit. Wipe down all dust particles and apply a primer. It is extremely important that the primer is
100 % dry before painting. I disassembled the armoire before painting as well. I brought the doors to a glass and mirror store and had a very thin mirror glued to the inner panels. Lastly I replaced all the hardware including the hinges. The before picture is from a catalog but is exactly what this piece looked like.hardware and all.
