Wallpaper Stripping
If you plan on painting the area you just stripped, you must ensure that all the glue behind the backing is removed. To tell if there is still glue remaining, wet the wall and feel it. Any slimy areas mean there is glue left over.
To remove any remaining glue, mix 2 tablespoons of liquid fabric softener into a gallon of water and scrub. You must also carefully rinse the entire wall surface so there are no traces of paste or wallpaper stripper remaining behind, before you paint.
