Step-by-Step Fix

Safety & Preparation

Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).

  1. Carefully lift the peeling edge of the wallpaper away from the wall to expose the underside. Apply a small amount of ready-mixed wallpaper adhesive directly to the back of the peeling seam using a small artist's brush or a clean finger, ensuring full coverage without oversaturating the paper.
  2. Gently press the seam back into position against the wall, aligning it perfectly with the original join. Hold it firmly for a few moments, checking that no air bubbles are trapped underneath and the seam is re-adhered along its entire length.
  3. Using a wallpaper seam roller, firmly roll along the entire length of the newly re-adhered seam. This helps to create a strong bond and smooth out any imperfections, ensuring the seam is flush with the rest of the wallpaper.
  4. Immediately take a clean, damp cloth and carefully wipe away any excess adhesive that has squeezed out from the seam. Ensure all visible adhesive residue is removed to prevent discolouration or a sticky finish once dry.
  5. Allow the adhesive to dry completely for at least 24 hours before touching or disturbing the area. Avoid placing furniture or objects against the freshly repaired seam during this drying period to ensure a lasting bond.
