How to make an outdoor chalkboard sign

Updated March 23, 2017

Chalkboard paint, which is available at any home improvement or craft store, can be used to turn almost solid surface into a blackboard. From small items like boxes or signs, to covering large walls, people use this versatile material for decorative and practical purposes. A restaurant may use an outdoor chalkboard sign to advertise its specials, or a business may use one to announce sales. The materials are inexpensive, and the project should take no more than an afternoon.

Drill any holes into the particleboard (if necessary) for the hanging hardware that you choose.

Prepare the area where you will paint by laying down the tarp. Be sure the area is well ventilated. Have all of your supplies within reach, and make sure all your brushes are clean and dry.

Lay the particle board on the tarp. Choose a board that is smooth on both sides, but if your board is rough on one side, be sure to lay the board with the smooth side up.

Paint the smooth side of the particle board with an even coat of chalkboard paint. Ensure that no specks of debris get onto the board while it is wet. If you find that your brush is leaving streaks, use a sponge roller to even out the paint. Allow the paint to dry for at least 30 minutes.

Apply a second coat of chalkboard paint, brushing perpendicular to your first layer of paint strokes. Make sure that your strokes are even and that the board is thoroughly coated with the paint.
