First, mark the walls for each panel (Image 1). The panels come in six 4’ x 4’ pieces, 3 for the top and 3 for the bottom. Then mark registration lines at the height of each wallpaper panel using a level (Image 2). This will help line up the panels evenly on the walls.
The glue that comes with the wallpaper is in powder form, so add some powder, a little at a time, to the water, stirring constantly (Image 1). The glue has a watery consistency, but make sure to get all of the lumps out before starting (Image 2). Once it's mixed, let it set up for about 5 minutes.
Paint the glue onto the back of the panel with long even strokes, making sure to cover the whole back surface. Allow the pasted panel to sit for one minute.
Bring the first panel to the wall and line it up with the level registration line.
Use a wallpaper brush to smooth out the panel from the center to the edges (Image 1). It is important to cover the edges and corners with plenty of glue to keep the wallpaper from peeling along the panel's edges (Image 2).
Once all of the big bubbles and bumps are smoothed out, use a wallpaper roller to flatten it further. Then, using a damp sponge or cloth, wipe away any excess paste from the surface of the wallpaper.
