Unpasted wallpaper requires applying adhesive directly to the wall or paper before hanging.

Unpasted wallpaper offers flexibility in adhesive choice and application method. The process involves preparing the wall surface, applying paste either to the wall or the wallpaper back, and carefully hanging each strip with proper alignment. Success depends on using the right adhesive, maintaining straight lines, and allowing adequate drying time.

Methods for Hanging Unpasted Wallpaper

Essential Tools and Materials

  • Wallpaper adhesive (clay-based or clear)
  • Smoothing brush or plastic smoother
  • Utility knife with sharp blades
  • Level and measuring tape
  • Drop cloths and painter's tape
  • Seam roller

Step-by-Step Hanging Process

  1. Prepare wall by cleaning, repairing holes, and applying primer
  2. Measure wall height and cut wallpaper strips 4 inches longer
  3. Apply adhesive to wall or paper back using recommended coverage
  4. Book the paper by folding pasted sides together for 5-10 minutes
  5. Hang first strip using level for perfect vertical alignment
  6. Smooth from center outward, removing air bubbles
  7. Trim excess at ceiling and baseboard with sharp knife
  8. Roll seams gently to ensure adhesion

Common Mistakes to Avoid

  • Using incorrect adhesive type for paper material
  • Applying too much or too little paste
  • Rushing the booking time, causing expansion issues
  • Overworking seams, which can stretch or tear paper
  • Ignoring pattern matching requirements

Tips for Professional Results

Temperature control matters significantly. Maintain room temperature between 65-75°F during application and drying. Avoid hanging wallpaper in high humidity or direct sunlight. Allow 48 hours minimum drying time before hanging artwork or pushing furniture against walls.

Removing Unpasted Wallpaper Later

Unpasted wallpaper typically removes more easily than pre-pasted varieties. Score the surface lightly, apply wallpaper removal solution, and let soak 15-20 minutes. Peel from top corner using wide scraper. Some adhesives may require additional steaming for complete removal.
