Build Your Own Giant Chalkboard | Pretty Handy Girl

Have you scoured antique stores or Craig’s List looking for a big giant vintage chalkboard? Those vintage school green chalkboards are highly sought after. But, hard to find. I have good news for you! You can build a Giant Chalkboard any size you want! (Although, typically you’ll be restricted to 4′ x 8′ if you want to use a sheet of masonite.) And you can mix your own chalkboard paint in any color.

Take out your notebooks, your pencils, and get ready to take notes.

Materials:

  • Masonite sheet cut to desired size (mine is 22″ x 48″)
  • 1×4″ pine boards for frame
  • 1 cup flat latex paint in color you desire
  • 2 tbsp. of unsanded grout
  • Pencil
  • Stain
  • White paint
  • Paint brush
  • Sanding block
  • Container to mix paint in
  • Kreg Jig
  • Drill
  • 1 1/4 inch pocket screws
  • Staplegun
  • 1/2″ staples

Instructions:

Pour 2 tbsp. of unsanded grout into your empty container. Add 1 cup of flat latex paint and stir well. (Yes, I used satin and it still worked.)

Paint the masonite with the chalkboard paint. Pull your brush in one direction. Then smooth out the paint by dragging the brush in a perpendicular direction.

Let the paint dry. Lightly sand and add a second coat of chalkboard paint.

Let that coat dry and sand smooth.

Assembling the chalkboard frame:

Cut the end of one of the 1×4″ boards at a 45 degree angle.

Mark 1/2″ inside the perimeter of your masonite chalkboard. Line up the interior edge of the 1×4″ with the corner of your penciled line.

Mark on the 1×4″ at the other end where the corner of your pencil line is. Cut your board from this point at a 45 degree angle. Cut a second board identical to your first board.

Continue marking and cutting for the other two sides.

Clamp the Kreg Jig on the end of the frame pieces and drill two pocket holes in the two longest sides.

If desired stain your frame and dry brush it white for a rustic and distressed look.

Rest the chalkboard onto the back of the frame. Check to  make sure the pencil lines line up with the pencil marks you made earlier.

DIY Projector:

To create my chalkboard message, I printed out my design on overhead paper. Then I taped it onto a stool and shone a floodlight flashlight through the mylar.

It worked fairly well as a DIY projector and it was cheaper and faster than going out to buy an overhead projector ;-).

The chalkboard is perfect for decorating over our fireplace.

I can change out the message depending on the seasons.

    Hello. Was the 1 cup of paint enough for 2 coats? I want to make a 32″ x 38″ board into a chalkboard and am wondering if 1 cup of paint will suffice or if I should make more. Thank you.
