8-panel world map wall mural
Ready-mixed wallpaper paste
You'll also need
Stanley knife; bucket; sponge; tape measure; spirit level; pencil; metal ruler; lint-free cloth; wall filler, undercoat and sandpaper (optional)
If wall to be covered isn't in good condition, fill in any cracks and holes and sand smooth. The smoother the wall, the better the wallpaper finish.
Wash wall with soapy water and dry. If it hasn’t been painted before, undercoat it and leave to dry (this is important as an untreated wall will suck paste from the paper and it won’t stick).
Using a tape measure and spirit level, mark horizontal and vertical centre lines of wall, creating a cross. Determine if entire mural fits your wall. If not, decide which panels you prefer to use and trim remaining panels so only 2.5cm remains for final trim. Decide whether you want to display more of the top or bottom of the mural.
NOTE: In this case, it was important for the lower section of the mural to be shown in full, so the manufacturer’s order of hanging was changed. The left-hand lower panels were trimmed and pasted first. This also meant taking into account the width of the wallpaper panels before measuring and marking a vertical line in from left-hand corner of wall to correspond. This line represents the vertical hanging guideline.
Brush paste generously on back of first wallpaper panel, as instructed by manufacturer. Be careful not to get paste on image side. If you do, wipe with the cloth.
‘Book’ wallpaper panel to allow for expansion (as wallpaper can expand up to 6mm in width). To do this, fold opposite short sides in to centre, paste to paste, without creasing at folds. Leave for 10 minutes to rest. Book 1 panel at a time. While waiting, brush paste on section of wall to be covered so you get more slip.
Re-paste any dry edges or areas prior to hanging. Referring to recommended or pre-determined order of hanging panels (see Note, left), place right edge of first panel directly on drawn vertical and/or horizontal lines. Allow for 2.5cm overhang at bottom (or extra at top). Using your hands and a lint-free cloth, smooth panel from centre out to edges. Any small bubbling will disappear when mural is dry. Immediately wipe off any excess paste with a slightly damp cloth.
Repeat Step 5 with second panel. Matching design, overlap the first by about 6mm, smoothing in place as in Step 6. To fix a mismatch or large air bubbles, slowly pull corners back and re-smooth (take care not to stretch panels). Repeat with remaining panels until wall is completely wallpapered.
Trim edges of surplus wallpaper using a sharp Stanley knife and metal ruler. Wipe panels with a clean, damp sponge to remove excess paste.
