Whether you've hung wall covering before or not, I'd like to offer these first-timer and advanced tips:
• More often than not, a first wallpapering project is either a kitchen or bathroom because they seem to be smaller rooms with less wallpaper. However, beginners should keep in mind that because there are so many partial walls and obstacles in these rooms, they are actually more difficult than a simple small bedroom.
• If you plan to miter the corners of a border, order one extra roll to cover cutting and waste. Mitering is a matter of finding the repeat in the wallpaper border and positioning it so that a mitered cut leaves a closely matched design. Use this technique for bordering windows, going around cabinets and tile or for vaulted ceilings.
• Test the paste on pre-pasted wall coverings to determine how long to soak them in water by putting two drops of iodine on different dry spots. If it turns brown, it indicates a starch-based paste requiring 15 to 30 seconds to soak. If it turns purple, the paste is cellulose based and only needs to be soaked for 1 to 15 seconds.
• If you are working with a large patterned paper, it's best to start at the ceiling with an entire design element versus cutting through the middle of a bouquet, for instance. If you can start with a little plain background at the ceiling, it will help to mask any unevenness where the ceiling and wall meet. If there is a coordinating border going over the top, make sure the bouquet or major element starts just below the edge of the border.
• When it comes to hanging paper, there are three very important rules. First, always use a level on every wall to maintain a true vertical line. Second, always cut inside corners, and then overlap the next sheet by butting it in the corner. Third, always wrap outside corners, also overlapping the next sheet to the corner.
• It's best and most efficient to work with a partner. Usually one person activates and books the strips while another does the hanging. Establish a rhythm and you won't get in each other's way.
• Keep wallpaper hanging books or guides in your tool kit for reference.
