Applying wallpaper over plaster walls is not difficult to do as long as the wall is properly prepared beforehand.
5 Steps To Wallpaper Over Plaster Walls
1. Ensure The Plaster Wall Surface İs Clean
If the wall was previously wall papered, be sure to remove all of the old wallpaper and wallpaper glue.
2. Remove Any Existing Mold With A Bleach And Water Solution
Use one part bleach to four parts water to remove the mold. Wash the plaster walls with the bleach solution and allow to dry completely. If you don’t have mold, you can skip this step.
3. Prime The Plaster Walls With A Latex Primer
4. Apply Wallpaper Sizing
After the latex primer has dried on the plaster walls, apply a coat of sizing. The sizing allows the wallpaper to slide into place.
5. Hang The Wallpaper
Once you have applied the coat of wallpaper sizing, you are ready to hang your wallpaper. Measure and cut your wallpaper in accordance with the measurements of the room. Apply the wallpaper glue, hang the wallpaper and use the smoothing brush to remove all bumps and air bubbles.
Tips and Warnings
- It is not absolutely necessary to apply wallpaper sizing. However, since it makes hanging wallpaper easier, it is best to apply.
- When you begin hanging wallpaper, it is best to start in a corner and work your way around the room.
- Only apply glue to the section of the wall you are about to hang the paper on. Do not apply glue to the entire room and then return to wallpaper it.
