How to Hang Wallpaper Like a Pro

W allpaper is the ultimate tool for transforming a flat, uninspired room into a structured, intentional space. While paint is forgiving, wallpaper demands patience and a keen eye for detail. When done correctly, the seams vanish and the pattern flows across the surface as if it were a single, continuous print, creating an immediate focal point that anchors your bedroom furniture. Success in wallpapering is 90% preparation. If your walls are porous or textured, the paper will eventually bubble or peel. The key is to create a slick, sealed surface that allows the adhesive to grab firmly. Treat the process as a measured, rhythmic task rather than a race, and you will find that the difficulty lies in the planning, not the execution.

1. Seal the Surface First. Remove old paper, fill holes with spackle, and sand the wall smooth. Apply a dedicated wallpaper primer to seal the drywall, ensuring it is fully dry before starting.
2. Find Your True Vertical. Measure out from the corner a distance equal to the width of your paper minus one inch. Use a level to draw a vertical plumb line from ceiling to floor.
3. Size Each Strip Exactly. Measure the height of your wall and add four inches for trimming. Unroll the paper and cut your first few strips, ensuring you account for the pattern repeat.
4. Book and Wait. Apply a uniform layer of heavy-duty wallpaper paste to the back of the paper using a roller. Fold the paper back onto itself (book it) for the time specified on the adhesive label.
5. Press from Center Out. Align the edge of the paper with your plumb line. Use a plastic smoother to press the paper against the wall, working from the center toward the edges to push out air.
6. Trim Sharp, Butt Tight. Use a fresh razor blade to trim the excess paper at the ceiling and baseboard. Slide the next strip into place, butting the edges tightly against the previous strip to align the pattern.
