Finding the right posters when decorating a bedroom, office or game room can add personality and style to your decor. Framing and hanging a poster is always an option, but you can also permanently hang a poster with a little wallpaper glue. Wallpapering posters is similar to hanging regular wallpaper, but you have a wide range of art styles and personal images to choose from. You can even create your own posters from personal photographs to hang on your walls.
Measure the dimensions of your poster. Choose a spot to hang the poster, then use a pencil to draw a rectangle or square on the wall that matches your poster's dimensions. Outline your square or rectangle with masking tape.
Apply wallpaper primer inside the taped-off area. Paint the primer evenly. Don't apply too much primer in one spot or it might drip below the tape line. Allow the primer four to six hours to dry.
Spread out newspaper and lay your poster on top with the image facing down.
Pour pre-mixed wallpaper glue into your pan and roll the paint roller through it. Roll glue onto the entire surface of the back of your poster.
Align your poster carefully into the taped-off and primered area. You may need to do some sliding to get it perfectly aligned, but slide carefully to avoid tearing your poster.
Smooth air bubbles from the interior outward with a plastic edging tool. Run the tool over the surface of the poster until the entire surface is completely smooth.
Remove the masking tape strips carefully.
