Written Instructions on How to Install Wallpaper
Read through the entire wallpaper installation instructions first, before rolling your sleeves up and getting to work!
Tools for Wallpaper Installation
- Tape measure
- Sponge smoother or sponge (not a plastic smoother)
- Exacto knife
- Large putty knife
- Clean cloth
- Fine sandpaper
- Bin for water
Paint and Primers
- You can hang this wallpaper over any latex paint that has cured (dried) for at least 30 days.
- If you need to paint the wall before hanging the wallpaper, please follow this guide:
- Latex paint in an eggshell, pearl or semi-gloss finish – paint and wait 30 days to hang your wallpaper
- Oil based primer – paint and wait 3 days to hang your wallpaper
- Zinsser BIN Lacquer Sealer – paint and wait 1 hour to hang your wallpaper
- NEVER hang this wallpaper over regular latex primer.
- If your wallpaper is white or light coloured, dark coloured paint may show through the wallpaper.
Sand and Clean the Wall
Sand down any bumps with a fine sandpaper, creating a smooth wall.
Wipe the wall with a damp cloth to remove dust and debris.
Surfaces Suitable for this Wallpaper
These wallpaper murals can be hung on any smooth wall with the appropriate painted finish (as mentioned above).
You can also install the wallpaper over clean glass or mirror with no prep work, or melamine and ceramic if painted with two coats of oil based primer or Zinsser BIN Lacquer Sealer.
About the Wallpaper Panels
- Each panel is numbered, so you know which order to hang them in.
- Each wallpaper panel is 18″ wide.
- Every panel overlaps the next by 1/4″ or 6 mm.
- Wallpaper panels expand by 1/8″ when wet.
- You can hang the wallpaper starting from the left side of the wall or the right side of the wall. To choose, imagine walking into the room and wanting the exposed side of the seam facing away from you to further hide the seams.
- You receive a crayon with your wallpaper. Gently rub the crayon on the exposed side of the wallpaper seam where the pattern is dark. Do this before you hang the panel on the wall to hide the white seams.
1. Measure the Width of Your Wall
Measure the width of your wall and compare it to the width of the wallpaper. Will you hang the wallpaper over the entire wall, from the left to the right? Or will you center the wallpaper mural on the wall with empty space on either side? Here are instructions for both types of installations:
A) Hanging Wallpaper Across the Entire Wall
If your wallpaper is slightly wider than the width of the wall, you’ll hang the wallpaper spanning the entire wall.
- Use your measuring tape and pencil to mark 17″ from the corner
- Draw a vertical line using your level at the 17″ mark
- Hang your first wallpaper panel against this line to ensure the mural is level and straight.
- Trim the excess 1″ off the wallpaper in the corner once the panel is on the wall, using your putty knife and the exacto knife. A corner is never perfectly level, and this allows a 1″ buffer.
B) Centering Wallpaper on the Wall Vertically
If your wallpaper is narrower than the width of the wall, you’ll center the wallpaper on the wall leaving blank wall space on either side of your mural.
- Figure out how much space you’d like to leave on either side of the wallpaper mural, taking into consideration furniture placement, doors, etc.
- Use your level and pencil to draw a vertical line on the wall.
- Align the outside edge of your first wallpaper panel to this level line.
2. Measure the Height of Your Wall
Measure the height of your wall and compare it to the height of the wallpaper. Will you hang the wallpaper over the entire wall, from the top to bottom? Or will you center the wallpaper mural on the wall with empty space on either side? Here are instructions for both types of installations:
A) Hanging Wallpaper from Ceiling to Baseboard
If your wallpaper is slightly taller than the height of the wall, you’ll hang the wallpaper covering the entire wall, top to bottom.
- Make sure there is a minimum of 1-2″ of excess wallpaper pattern to trim off at the ceiling at baseboard, not including the white panel numbers.
- Do not pre-trim the wallpaper before hanging on the wall. Trim the excess with a putty knife and exacto knife after the panel is applied to the wall.
B) Centering Wallpaper on the Wall Horizontally
If your wallpaper is shorter than the height of the wall, you’ll center the wallpaper on the wall leaving blank wall space on the top and/or bottom like I did for celebrity designers Colin & Justin on Cityline.
- Figure out how much space you’d like to leave on the top and/or bottom of the mural.
- Use your level and pencil to draw a horizontal line on the top of the wall where you want your mural to hang from.
- Pre-trim the white panel numbers off of the wallpaper.
- Align the top of your wallpaper panel to this level line.
3. Hang Wallpaper on the Wall
- Fill a bin with lukewarm water and place it against the wall
- Roll your first wallpaper panel, starting at the bottom, with the pattern facing inwards (prepasted side facing outwards). The top of the wallpaper should be on the outside of the roll.
- Dip the rolled up wallpaper into the warm water for 15 seconds.
- Slowly pull the panel out of the bin, climbing the ladder.
- Place the wallpaper on the wall and slide the panel up against the level line(s) you drew.
- You can pull the panel off and reposition if you need to, but the wallpaper panel will slide around on the wall for up to 2 minutes making it easy to line up.
- Gently smooth any air bubbles out with your sponge smoother, taking care not to apply too much pressure.
- Trim any excess wallpaper at the top, bottom and/or down the side using your putty knife and exacto knife. Change your exacto blade often.
- Gently wipe the seam, baseboard and ceiling with a damp cloth to remove residual paste.
- Repeat this procedure with the next panel, overlapping the first seam by 1/4″.
- Ensure each panel is straight by using your level. Remember, panels will gently slide on the wall for up to 2 minutes, allowing you to make corrections as you go.
