19 Wallpapering
Wal paper has been popular for centuries,
particularly in formal rooms, where there’s less
danger from little ones’ grimy fingers and rowdy
ways. Paint has long been favored for rooms that
get the most use and abuse because it’s durable
and easy to clean and apply.
Today, wallpaper is available in so many
materials—including grasses, bamboo, rice
paper, foil, and cork—that they are collectively
called wallcoverings, and some of them are stron-
ger, more durable, and easier to maintain than
some paints. Many are backed with paper or
cloth, with cloth being stronger. But by far the
most popular are vinyl-coated wallcoverings,
which are washable and grease-resistant.
Most wallcoverings come prepasted. This
makes them easier to apply and—years later—
easier to strip from the wall. Because the manu-
facturer has already pasted the covering, all you
need to do is unroll it and soak it briefly in a
water tray. As you’ll see in this chapter, many
pros avoid the drips and mess of a water tray by
rolling a prepaste activator onto the backing.
Selecting Materials
Choose a wallcovering whose pattern and color
are appropriate for the room. There are no hard
and fast rules on what works. But in general,
lighter colors make rooms look larger, and darker
colors make rooms look smaller. Smaller, sub-
dued patterns are better for quiet rooms. Splashy
floral prints tend to serve better in places such as
front halls that bustle with activity. Delicate tex-
tiles or grasses are best reserved for rooms with
To hang wallcovering, start by unfolding the top half of a
pasted strip and carefully align it to a plumbed line or to
the plumbed edge of the preceding strip.
