Wallpapering 3 - Getting Ready Wallpapering 3 - Getting Ready

What You Will Need

Time. Wall-papering will average 10 to 20 minutes per sheet, longer if encountering trim.

Tools for Wallpapering.
Wallpapering takes some very specialized but simple tools. As always, never skimp on quality. You will only regret it later. Most stores sell wallpaper application kits which include a full set of tools that will cover most of your needs. See the linked checklist for other tools you will need.

Materials for Wallpapering. Space is not available in this project to describe all the many types of wall coverings. Consult your supplier or a good wallpapering book for complete information. However, in choosing your wallpaper, most DoItYourselfers prefer to purchase the pre-pasted type with adhesive on the back Avoid the older types where paste must be applied. You can spend days thumbing through a pattern book Estimating wallpaper materials. Multiply the perimeter of the room by the height of the walls to arrive at a total square footage. Divide this by 30. (The average American single roll contains 35 to 36 square feet, but there will be losses due to trim and pattern matching waste.) European papers contain 27 to 28 square feet per single roll and are packed in double rolls of 55 to 56 square feet per bolt. Use a figure around 24 for calculating Euro Rolls. As most US manufacturers also import and export, always be certain of roll sizes. Some pattern matching and shrinkage require more rolls (check with your supplier). This new number is your number of rolls if you had no openings. Subtract 1/2 roll for each normal size door or window opening. This number covers your final needs. Purchase all rolls in one order to avoid variation in stock

Most Common Mistakes

As with painting, the most important and often overlooked step is preparing the wall you are about to work on. Preparation, patience, and an eye for detail are all you need to avoid these common mistakes:

  1. Not sanding, cleaning, and sizing the walls before applying the wallpaper.
  2. Failure to soak the pre-pasted wallpaper long enough.
  3. Failure to allow the wall-covering to cure the proper amount of time after soaking.
  4. Letting the wall-covering paste dry on the woodwork.
  5. Not positioning the strips of the wallpaper level and plumb.
  6. Not getting air pockets out when smoothing the covering on the wall.
  7. Not planning for pattern match-up and extra on top and bottom before cutting each strip.
  8. Not estimating and ordering enough wallpaper for the job.
  9. Not allowing the sizing to dry.
  10. Not overlapping the wallpapers that have a tendency to shrink,
  11. Using a seam roller on embossed wallpaper.

Planning the Project

Proper planning is essential to obtaining a professional looking hanging job. Planning involves mostly understanding where the rolls will be applied and where they will meet at seam lines. Also, you have to consider adjustments so that patterns match, once you start to hang it.

The first thing you have to do is determine where you plan to start. This will determine the location of the point of mismatch where odd-shaped pieces will need to be cut You want to plan this so that these mismatched points are in the least visible locations. These mismatch points are more important when using a design with large patterns. With a neutral or a non-directional pattern, you can begin at an inconspicuous corner or area of the room. Usually the best place to start with all wallpapers is an inconspicuous corner.
