A Beginner’s Guide to Sizing a Wall Before Wallpapering

Are you gearing up to wallpaper a room in your home but unsure where to start? One crucial step that often gets overlooked is properly sizing the wall before applying the wallpaper. Sizing is the process of prepping the wall surface to ensure optimal adhesion and a smooth finish for your wallpaper. Let’s delve into the basics of how to size a wall effectively.

Why Size Your Wall?

Sizing serves multiple purposes:

  1. Promotes Adhesion: Sizing helps the wallpaper adhere evenly to the wall surface, preventing air bubbles and wrinkles.
  2. Smoothens the Surface: It seals porous wall surfaces, such as drywall or plaster, creating a smoother base for the wallpaper.
  3. Eases Removal: Properly sized walls make it easier to remove the wallpaper in the future without damaging the underlying wall.

Materials Needed

Before you begin sizing your wall, gather the following materials:

  • Wallpaper sizing solution
  • Paint roller or sponge
  • Paint tray
  • Drop cloth or plastic sheeting to protect the floor

Step-by-Step Guide

  1. Prepare the Room: Remove any furniture or obstacles from the wall you’ll be working on. Lay down a drop cloth or plastic sheeting to protect the floor from spills.
  2. Clean the Wall: Use a damp cloth to wipe down the wall surface, removing any dust, dirt, or grease. Allow the wall to dry completely before proceeding.
  3. Mix the Sizing Solution: Follow the manufacturer’s instructions to mix the wallpaper sizing solution with water in a paint tray. Typically, you’ll use one part sizing solution to three parts water, but this can vary depending on the product.
  4. Apply the Sizing: Dip a paint roller or sponge into the sizing solution and apply it evenly to the wall surface. Start from the top of the wall and work your way down in smooth, overlapping strokes. Be sure to cover the entire surface with a thin, even coat of sizing.
  5. Allow to Dry: Give the sizing solution ample time to dry according to the manufacturer’s recommendations. This typically takes around 30 minutes to an hour, but it’s essential to follow the specific drying time indicated on the product label.
  6. Inspect the Wall: Once the sizing has dried, inspect the wall surface for any imperfections or areas that may need touch-ups. If necessary, apply an additional coat of sizing to ensure complete coverage.
  7. Ready for Wallpaper: Your wall is now properly sized and ready for wallpaper! Proceed with hanging the wallpaper according to the manufacturer’s instructions, and enjoy your newly transformed space.

By taking the time to properly size your wall before wallpapering, you’ll ensure a professional-looking finish that will last for years to come. With these simple steps, you can tackle your wallpapering project with confidence and achieve stunning results.
