Prep shutter by lightly sanding any rough or glossy surfaces; wipe with clean, damp cloth to remove dust or debris.
Using the flat brush, paint the shutter, being careful to apply evenly in between the slats; allow paint to dry, following suggested drying time on the can label.
Optional: Apply a second coat of paint for added durability.
If needed, fasten picture-hanging hardware to the back of the shutter, according to the instructions supplied in the kit.
Hang finished shutter on the wall.
