Step by step guide to make a blacklight poster

Step 1

To begin creating a blacklight poster, gather several pieces of construction paper in the same color. Many colors are available in-store, but fluorescent colors work best for this project. When you’re out shopping for paint, don’t forget to pick up some white glue. Pick up some markers (black works best) and a black light as well.

Step 2

You’ll need to cut several different shapes out of construction paper. The size is determined by how large you want your blacklight poster to be, but each piece should extend about a foot beyond the edge of the base material (for example, if you’re using a standard 12 x 18-inch sheet of construction paper, cut each piece to 11 x 17 inches).

Step 3

Then glue each piece of paper to a single sheet of poster board. Hold the pieces together and dab white glue on all four sides. Allow it to dry for about one minute before flattening it with a stack of heavy books or a heavy object. A poster board holder is another great option for keeping everything flat and smooth.

Step 4

Now that you’ve made a blacklight poster, it’s time to color it! Dip your paintbrush into the fluorescent paint, being careful not to dribble. Because the paint will easily drip, use a light touch when applying it to avoid making a mess. Begin by covering as much space as possible on one side of the poster in 10 seconds. When you’re finished with one stroke, grab another piece of construction paper and go over the remaining surfaces again. It is necessary to apply several coats of paint to achieve the best results, so plan on spending some time or more depending on how many layers you want.

Step 5

Allow your black light poster to dry for at least one hour after you finish painting it so that it is ready to display.
