How to prepare a wall for wallpapering?

Preparing a wall properly before wallpapering is essential to achieve a long-lasting and aesthetically pleasing result. Here are some general steps you can follow:

  • Cleaning:
    • Start by cleaning the wall to remove dust, dirt and grease. You can use a mild solution of water and detergent.
    • Make sure the wall is completely dry before proceeding.
  • Repair of cracks and holes:
    • Fill any cracks or holes in the wall with wall putty. Smooth the putty with a putty knife and make sure it is dry before continuing.
    • If there are larger imperfections, you may need to sand the wall to obtain a smooth surface.
  • Sanding:
    • Sand the wall to smooth out any irregularities and provide a sticky surface for the wallpaper.
    • Use medium grit sandpaper to remove imperfections and fine grit sandpaper to smooth the surface.
  • First:
    • Apply a coat of primer to the wall. This helps the paper adhere better and provides a uniform surface.
    • Make sure you use a primer suitable for the walls and that it is dry before continuing.
  • Measuring and cutting:
    • Measure the height of the wall and cut the wallpaper strips according to those measurements, leaving excess for adjustments.
    • It is important to follow the wallpaper manufacturer's instructions for proper handling and cutting.
  • Wallpapered:
    • Apply the adhesive paste according to the manufacturer's instructions on the back of the wallpaper.
    • Place the wallpaper strips on the wall, lining them up correctly and smoothing out any air bubbles with a brush or sponge.
  • Cutting and adjustments:
    • Use a sharp blade to cut off excess paper at the edges and corners.
    • Make sure the joints are well aligned and there are no overlaps.
  • Drying and touch-ups:
    • Let the wallpaper dry completely before making any additional touch-ups or adjustments.
    • If necessary, apply more adhesive paste or make adjustments to the edges for a clean finish.

By following these steps, you will be able to properly prepare the wall for wallpapering and achieve a satisfactory final result. Always remember to follow the specific recommendations of the wallpaper manufacturer and the products you are using.
