How to Make Poster Paper More Rigid & Sturdy

Although poster paper is stiffer than regular paper, it's still flexible and easily bends in the wind. If you are going to carry or hang the poster outside, reinforcing it will help it withstand transport and exposure to the elements. You can secure the poster board with several layers of poster paper and glue to make it sturdier. Reinforce the poster before you write or draw on it to prevent the ink from coming into contact with the glue.

Instructions

Things You'll Need

• 4 pieces poster paper, all the same size
• Clear, quick-drying craft glue

1. • 1
     Lay a piece of poster paper on a flat surface.
   • 2
     Apply a thick strip of glue (about one-quarter of an inch wide) along all four sides of the paper, about one-half inch from the edge. Be sure to read the directions on the bottle of clear, quick-drying craft glue to see how long it takes to dry when applied to poster paper.
   • 3
     Lay a second piece of poster paper directly on top of the first one. Press along the edges of the top piece with your hand to adhere the posters together.
   • 4
     Leave the poster papers to dry as directed on the glue bottle.
   • 5
     Apply a strip of glue along each side of the top piece of paper, the same as you did with the first one. Repeat steps 3 and 4 to apply a third sheet of paper to the poster.
   • 6
     Repeat Step 5 to glue a fourth (and final) sheet of paper to the other ones.
