The wall must be smooth, clean, and dry. Remove old wallcoverings, fill holes, sand smooth, then prime the entire surface (we recommendShieldz Universal Wallcovering Primer).

Use a level and pencil to draw a vertical plumb line from ceiling to floor at your starting point. Never use a corner or baseboard as your guide — walls are rarely perfectly square.

Fold the panel loosely onto itself — pasted side to pasted side — without creasing the folds. Let it rest for5–8 minutesso the paste can absorb and the panel can expand to its final size. Skipping this is the most common cause of seam gaps.

Trim excess at the ceiling and baseboard using a metal straightedge and craft knife — one confident cut, no sawing. Change the blade every 1–2 panels. For outlets, cut an X and trim the flaps (turn off power first).

Butt each panel edge-to-edge with no overlap or gap, checking vertical alignment with your level as you go. Allow the finished installation to dry undisturbed for 24–48 hours— avoid drafts, direct heat, and open windows.
