Enhance the look of your medicine cabinet by refinishing it with a durable, glossy enamel. Before paint, consider a few crucial points. Whether your medicine cabinet is made of wood or metal, it will not accept a new finish until it is prepped with a base primer. Choose a certain type of primer based on the cabinet's composition, or flaking is inevitable. Apply the primer and painted finish, using the right technique, or sags and runs will show in your final results.

Things You'll Need

  • Coarse sponge
  • Water-based degreasing cleanser
  • Rags
  • Towels
  • Masking paper
  • Professional painter's tape
  • Drop cloths
  • Latex spray primer
  • Metal etching spray primer
  • Acrylic spray enamel
  • Oil spray primer
