Good wallpaper results start before the first strip goes up. Nursery walls need to be dry, clean, stable, and smooth so the paper adheres properly and the finished surface looks even. Before choosing an installation date, check for damage, moisture, loose paint, and old coverings that could affect the result. Taking time to prepare also helps prevent common problems such as bubbling, peeling edges, and visible bumps beneath the wallpaper.
Check the Wall Condition
Inspect every wall in daylight and look closely around windows, corners, and the ceiling line. Watch for cracks, dents, flaking paint, water stains, or areas that feel soft. Press gently on suspicious spots; a surface that shifts or crumbles needs attention before wallpaper can be applied. If you find signs of an active leak or persistent dampness, resolve the cause first rather than covering it.
Check whether the existing paint is firmly attached. Rub a small area with a clean, damp cloth; if paint transfers or flakes, the surface may need scraping and repair. You can also score a small, discreet patch with a utility knife and apply painter’s tape, then pull it away. If paint comes off with the tape, remove unstable paint and prepare the wall before installation.
Remove Old Wall Coverings
In most cases, remove existing wallpaper instead of applying new paper over it. Old seams and texture can show through, while loose sections may prevent the new adhesive from bonding. Strip the wallpaper and its backing, following the product instructions for the removal solution or steamer you use. Protect the floor and nearby trim, and avoid soaking plasterboard, which can be damaged by excess moisture.
After stripping, remove leftover paste with a suitable cleaner and clean water, then let the wall dry completely. Pay special attention to corners and seams, where adhesive residue often remains. If the old wallpaper will not come off cleanly or the wall underneath is damaged, pause to assess the surface rather than covering the problem with a new layer.
Repair and Smooth the Surface
Fill small holes and cracks with an appropriate wall filler, then let it dry as directed. Sand repaired areas until they sit flush with the surrounding wall. Remove sanding dust with a vacuum brush or a clean, dry cloth; dust left behind can interfere with adhesion. For larger defects, damaged plaster, or uneven joins, arrange repairs before wallpapering so the finished surface does not highlight them.
Check the wall for ridges, rough patches, and raised paint edges by running your hand lightly over it. Wallpaper can conceal minor color differences, but it will not hide bumps or uneven repairs. Use the correct primer or wallpaper sealer for the wall material and the wallpaper adhesive. Primer helps create a consistent surface and can make future removal easier; follow the manufacturer’s drying instructions.
Clean, Dry, and Ready
Before installation, remove dust, grease, and marks with a suitable cleaner, then rinse if the product requires it. Let the wall dry fully and keep the room ventilated. Do not apply wallpaper over a cold, damp, or freshly painted surface. Check the paint or primer label for its recommended drying time, and confirm that the wall feels dry and smooth before work begins.
Move furniture away from the walls and protect the floor. Remove or safely cover switch and outlet plates, and make sure the power is off before working near electrical fittings. Keep the wallpaper, paste, and tools organized, and confirm the wall measurements and paper pattern direction. These final checks help avoid interruptions once installation starts.
A careful wall check, thorough removal of old coverings, and proper cleaning and repairs give nursery wallpaper a sound surface to bond to. Address moisture and loose finishes before installation, and allow each preparation layer to dry fully.
