Lay down old towels around the work area, and make sure none of your carpeting or hard floors remain visible. This protects your floors from damage. Further, the towels absorb liquids during the removal process.
Rub the vinyl wallpaper with sandpaper to create pores. In later steps, you must add wallpaper solvent to dissolve the adhesive but some vinyl wallpapers do not absorb any liquids due to a lack of pores. The sandpaper creates pores and allows the vinyl to absorb the solvent. Wear a face mask during this step.
Dip your paint roller into store-bought wallpaper solvent, and apply the solvent to the vinyl wallpaper. Work in small sections since the solvent can seep through and damage the drywall. Do not let any solvent stay on the wallpaper for more than 15 minutes.
Pull the wallpaper from the wall carefully. The solvent allows the wallpaper to detach with moderate effort. Avoid pulling with most of your strength as this can damage the drywall.
Lay down a strip of wallpaper on a long table, and apply wallpaper adhesive with a paint roller. Fold the wallpaper so both ends meet in the center, but do not let the paper crease. Performing this step, referred to as "booking," activates the adhesive.
Apply the wallpaper to the wall. Use a ladder to reach high areas. Flatten out the wallpaper with a flat-edged tool and use a moist sponge to fit the wallpaper into corners. Remove overhanging pieces of vinyl wallpaper with a utility knife.
Continue Steps 1 and 2 until you cover the entire wall. Use your utility knife or scissors to cut into the vinyl wallpaper to fit corners, doorways, windows and molding.
