More in Windows Walls and Doors
Take the second sheet of pasted paper and position it below the first (Image 1). Continue down the wall surface using the same techniques.
When you get to the bottom of the wall, trim the paper against the baseboard or floor using a utility knife (Image 2). Wipe any paste from the baseboard. Before starting on the next wall, cast an eye across each hung length. Check for bubbles and smooth again if necessary.
Draw a vertical pencil line on the wall surface at your chosen starting point. Check and recheck this line using a level (Image 1).
Pick up the "book" of folded paper and unfold the top section. Position it against the guide line (Image 2).
When you are happy that the paper is level, brush it down from the top and crease it into the junction (Image 3). At the same time, ensure that the vertical edge of the paper is precisely aligned with the pencil guide line.
Unfold the book and work your way down the wall to the floor or baseboard. Be careful not to crease or tear the paper. Keep checking that the sheet is vertical (Image 4).
Use the brush to smooth the paper over the wall and remove any bubbles. Work from the center of the paper to the edges (Image 5).
At floor level, use the brush to crease the paper into the junction between the wall and baseboard (Image 6).
Brush back up the paper to ensure good adhesion (Image 1). Pay particular attention to the edges and to removing air bubbles.
Trim at the top and bottom of the length using whichever method you prefer. If you use scissors, mark the crease with a pencil line (Image 2).
Brush the trimmed edges tight against the ceiling and baseboard (Image 3).
Use a clean, damp sponge to wipe away any excess paste from wallpaper surface. Do the same for the ceiling and baseboard (Image 4).
Make sure that the pattern is matched at eye level; this keeps any pattern drop (or misalignments) at a high or low level (Image 1).
Butt the edges together tightly, checking the seam as you work your way down (Image 2).
Clean the seam with a wet sponge to remove any excess paste; do not apply too much pressure as this creates a shiny seam when the paper is dry. Finish off by gently running a seam roller up and down the seam (Image 3).
