Mounting a poster on foam board not only gives it a stable backing but also makes display and framing much easier. While you could use regular craft glue, there's a high risk of damaging the poster and leaving wrinkles and ridges. Other options will leave your poster pristine and make for an attractive display.

Quick and Simple Attachments

Step 1

Place the foam board on a flat surface.

Step 2

Center the poster on the foam-core sheet.

Step 3

Place books, soup cans or other heavy objects on the poster to hold it in place.

Step 4

Lift a corner of the poster and place a 2-inch strip of double-sided transparent tape on the foam board, directly under the corner of the poster.

Step 5

Peel the protective backing from the tape and press the poster corner onto it.

Step 6

Move across the top of the poster, about a quarter of the width, and place another piece of tape. Repeat about halfway and about three-quarters of the way across, as well as in the next corner.

Step 7

Repeat the tape placement along each side and the bottom of the poster.

Step 8

Remove the weights.

Securely Removable Solutions

Step 1

Set the foam board flat on your work surface.

Step 2

Slide the corners of the poster into self-adhesive photo corners.

Step 3

Position the poster on the foam board.

Step 4

Remove the backing from the adhesive side of the photo corners and press them onto the board.

Spray Away to Adhere It

Step 1

Lay the foam board on a flat surface.

Step 2

Place the poster on the board with the back side facing up.

Step 3

Spray the back of the poster lightly with an acid-free spray adhesive.

Step 4

Turn the poster over carefully and position it on the board.

Step 5

Smooth the poster from the center to the edges, using either the side of your hand or a ruler.


Clamping the edges of the poster to the board can help make the spray adhesive more permanent.


Be sure to use acid-free paper and adhesives to preserve the integrity of your poster as time goes by.
