Pick the room where you want to hang the mural wallpaper. Then choose the wall that will best handle the mural. That wall should have few outlets or light switches that will interrupt the flow of the mural.
Treat the area of wall that you want to hang the mural wallpaper. Use a blend of vinegar and water to get rid of any debris, dirt or oils that may affect the hanging of the mural.
Unwrap the paper and be sure that it has all the pieces that belong to it.
Decide the precise mark will the mural will begin. Be sure that you make this border straight. Use a straight edge ruler or a plumb line to determine that it is accurate.
Place the first section on a level surface. Apply a thick even coat of adhesive to the entire panel. Be sure not to miss any part of it, including the edges. Place the panel inside out and wrap it up to allow the adhesive a few moments to dry.
Place the panel on the wall. Be careful to line it up evenly with the line you made in Step 4. As you place the panel on the wall slowly unravel it being careful not to break the paper.
Gently smooth out the bubbles under the paper using a cloth or your hand.
Repeat Steps 5 to 7 with the remaining panels.
Allow the paper to dry thoroughly.
