Instructions For DIY Magnetic Board Outdoor :

Collect Your Materials

First, prepare your picture frame. Make sure it’s clean before removing the glass, mat, and backing. Next, get your metal pieces. Galvanized steel is magnetic, comes in a variety of sizes, and may be ordered online or purchased at a hardware shop. Make sure the size fits in your picture frame the same way a photo or print would.

Make The Metal

It’s time to start preparing the galvanized steel. Rough up the metal’s surface with a little piece of fine sandpaper. You’re not seeking to completely sand it down; a short, light sanding would be enough for this endeavor. Before you begin painting, wipe off the metal surface with a clean microfiber cloth to ensure it is clean and dust-free.

Begin Priming

Set up your spray painting station in a well-ventilated area, and place a drop cloth or tarp underneath the sheet of metal to catch any leftover paint. First, apply a uniform layer of black primer paint to the metal (a can of flat-finish black primer spray paint is a good choice).

Allow it to dry for about 30 minutes. If you believe the metal requires more coverage, apply a second layer of primer and allow it to dry completely.


When working with spray paint, make sure you’re in a well-ventilated place, preferably outside. Wear a mask to avoid breathing in any harmful fumes from the spray paint.

Apply Chalkboard Paint

After the primer has cured, it’s time to apply the chalkboard paint. You can use conventional chalkboard paint and a roller or brush, but chalkboard spray paint adheres better (less possibility of peeling!) and is much easier to use.

Spray an even layer of it onto the prepared metal, making sure that every part is coated. Allow it to dry (it should be tack-free after about 30 minutes), then spray a second coat to ensure complete coverage. After an hour, the sprayed sheet should be completely dry and suitable to handle, but double-check before moving it.

Prepare The Frame And The Surface

When the sprayed metal is finished, place it into the picture frame and fix it with the frame backing as you would any other photo or print. Allow the chalkboard paint to cure for 24 hours before using any chalk on the surface.


To prepare your finished DIY magnetic board for chalk use, rub the entire surface with the side of a chalk stick, coating the entire thing equally. Seasoning the chalkboard accomplishes the same goal as priming paint. It guarantees that the chalk writing goes on easily and that there is no sign of the original writing or image you put on it.

There you have it, a magnetic message board! Simply hang your creation using sawtooth picture hangers.
