How to Make a Wall Collage With a Clear Coating

Wallpaper Paste

• 1

  Cut out all the paper images you want to use using a pair of scissors. If you are using a large sheet of newspaper as the backing for your wall collage, you will need many small images or several larger images.

• 2

  Glue these images to a large sheet of newspaper. If they are irregular in shape, overlap them, and if they have straight edges, butt them up next to each other. The less white spaces you have, the better the collage will look.

• 3

  Apply a thin coat of decoupage medium to seal the images in using a paintbrush. This clear coat allows the pictures to look their best by adding a shine to the surface while simultaneously protecting the images.

• 4

  Allow the decoupage medium to dry thoroughly. The amount of time varies from medium to medium, so check the packaging for more precise details.

• 5

  Apply a strippable wallpaper paste to the back of the newspaper using a paintbrush.

• 6

  Mount the collage by laying it against the wall, pressing it flat with your fingers.

  Press the side of the poster board bearing the adhesive putty to the wall where you want the wall collage to hang. Press it against the wall firmly for several seconds, which activates the putty.
