Paint, an effective and inexpensive way to update a room, can also be used to give window blinds a fresh look. The number of painting steps required depends on the type of blinds you are painting -- plastic, aluminum or wood.
Prepare the Blinds
Open the blinds while they are hanging. Use the soft cloth to gently wipe away any dirt and dust. Dampen the cloth with water and rub away any stubborn debris. Allow blinds to dry thoroughly if water was used. A simple dusting should be sufficient for new blinds that are not yet hanging.
Cover the blind's cord with painter's tape to retain their original color. Be sure to cover the cord on both sides of the blind.
For wood blinds only: Lightly sand the slats of wood blinds on both sides while the blind is still hanging. Brush away dust with cheesecloth. Wipe the window sill with a dampened cloth.
Move the blinds outdoors to a large flat area for flat painting, or a fence, bench or clothesline that allows you to hang the blinds while painting. Cover the selected area with old newspapers or a dropcloth.
Remove the blinds from the window if they were previously hung. Remove the end caps from both ends of the top of the previously hung blind. Take blind and end caps to the outdoor painting area.
Place the blinds and end caps on the painting area. Arrange the slats so they are open. Place the end caps on a flat surface covered with newspaper or a piece of dropcloth if you're hanging theblinds to paint them.
Paint the Blinds
Aluminum, wood and dark-colored plastic blinds: Shake spray primer according to the directions on the can. Spray the blinds evenly using short strokes in a back-and-forth sweeping motion. Allow them to dry thoroughly; then turn the blind over and repeat on the back side. Allowthem to dry thoroughly before painting. Skip this step if painting light-colored plastic blinds.
Shake the spray paint according to the can's directions. Spray the blinds evenly using short strokes in a back-and-forth sweeping motion. Allow that side to dry thoroughly; then turn the wand of the blinds to expose the back side. Spray the newly exposed area of the blinds evenly using short strokes in a back-and-forth sweeping motion. Allow to dry thoroughly. Check the edges of the blinds. Touch up any areas not reached by the paint with the artist's paintbrush and a small amount of paint sprayed into the disposable container/paper plate. Allow to dry thoroughly.
Determine if the blinds will need a second coat of paint. Add another coat if the paint is blotchy or patchy and allow it to dry thoroughly after the second coat. Be sure to flip the blind over to add another coat to the other side, too. Touch up edges as needed using the artist's paintbrush and a small amount of paint sprayed into the disposable container.
Paint the end caps using short strokes in a back-and-forth sweeping motion. Start with a coat of primer if they are made of wood, aluminum or dark-colored plastic. Allow them to dry before painting. Add a second coat of paint if necessary. Allow them to dry before replacing caps and blinds into the window hardware.
