There's a home improvement specialist demonstrating how to remove wallpaper from walls.  He starts of by preparing the space by moving furniture away from the walls and covering the furniture with plastic sheets for protection.  He also removes the window treatments from windows.  He shows how to take precautionary measures with respect to electrical wiring and switches and circuits.  Then he shows how to use fans to ventilate the room.  He takes a scour and begins to scour the wall paper.  He uses a paint roller to soak the wall paper for easy removal.  He then demonstrates how steam can be used too to loosen the wall paper.  Then he begins to slowly peel off the paper from the wall.  He re-wets the surface and uses a flat tool to remove any stubborn wall paper.  He finally uses a sponge and soap water to clean the wall to remove any residual wall paper.  He shows how to apply primer to prep the wall for painting.  Information on how to use these techniques is provided on the Lowe's company website.
