  To determine exactly where wallcovering

  seams will occur, mark off intervals the same

  width as your wallcovering. Go around the room,

  using a ruler or a wrapped roll of wallcovering as

  your gauge. Try to avoid trimming and pasting

  very narrow strips of wallcovering in corners;

  this usually looks terrible, and the pieces don’t

  adhere well. You may want to move your starting

  point an inch or two to avoid that inconvenience.

  However, if the pattern is conspicuous, you

  might start layout with a strip centered in a con-

  spicuous part of a wall—over a mantel, over a

  sofa, or in the middle of a large wall. Choose a

  Basic Papering Techniques

  Before you start hanging wallcovering, turn off

  the electricity to affected outlets, switches, and

  fixtures, and check with a voltage tester to be

  sure the power is off.

  Use shears to rough-cut strips, leaving extra at each end for trimming and pattern matching. This pasting and layout table is a professional model, strong yet light, easily transported from job to job.

  Three Types of seams

  you can join strip edges in three ways: butt seam, overlap seam, or double-cut seams.

   The butt seam is the most common. its edges are simply butted together and

  rolled with a seam roller.

   an overlap seam is better where corners are out of square or when a butt seam

  might occur in a corner and not cover well. Keep the overlap as narrow as possible,

  thereby avoiding a noticeable welt and patterns that are grossly mismatched.

   Double-cut seams (also called through-cut seams) are the most complex of the

  three. They are used primarily where patterns are tough to match or surfaces are

  irregular; for example, where the walls of an alcove aren’t square.

  than half the pattern. The pattern along the base-

  board will be less visible and less important.

  On your cutting table, place the second strip

  next to the first, and align the patterns along

  their edges with two strips side by side. You’ll

  have a sense of how much waste to allow for pat-

  tern matching. (A pattern-repeat interval is often

  printed on the label packaged with the wall-

  paper.) Depending on the size of the patterns,

  each succeeding strip can usually be rough-cut

  with an inch or two extra at each end and then

  trimmed after being pasted.

  Do the rough-cutting at the table using shears.

  Do the trimming on the wall using a razor knife.

  Patterns that run horizontally across the face of a

  covering are called straight match. Patterns that

  run diagonally are called drop match and waste

  somewhat more material during alignment.

  Unless you are working with a delicate cover-

  ing, cut several strips at a time. But be careful

  not to crease them. Flop the entire pile of strips

  facedown on the table so the piece cut first will

  be the first pasted and hung. The table must be

  perfectly clean; otherwise, the face of the bottom

  strip could become soiled.

  powder or water slowly: Even small increments

  can change the consistency radically. Finally, mix

  thoroughly to remove lumps.

  As you work, keep the pasting table clean,

  quickly sponging up stray paste so it won’t get on

  strip faces. Some coverings, such as vinyl, are not

  marred by stray paste on the face, but many oth-

  ers could be. Although the batch of paste you mix as you apply paste, roll it out from the center toward the edges. Hold down the wallcovering with should last a working day, keep an eye on the
