Most renovation projects or new construction utilize gypsum wallboard
as the preferred choice for finishing interior walls. Once wallboard
has been installed and joints taped and sanded, walls can be paneled,
painted, wallpapered, or textured. For walls that will be textured,
texture is applied before adding a coat of primer and paint.
Texturing not only adds character to the wall. It also efficiently
covers any flaws or imperfections in the joint taping work. Since
“perfect” wallboard joint taping is more likely achieved
by a professional drywaller, DIY homeowners who undertake a wallboard
project are more likely to add texture to their walls.
The Two Most Popular Types of Texturing
One of the most common types of wall texturing is “orange
peel;” also known as “eggshell” or “splatter.”
Small splatters of thinned drywall compound are sprayed onto the
wall; the finished result is a roughened texture much like the outer
peel of an orange.
Another type of texturing that is popular is called “knock-down,”
also known as “skip trowel.” This is accomplished by
spraying spatters of thinned drywall compound onto the wall. After
it has started to set up, it is gently smoothed using a 12-inch
drywall knife or trowel to flatten the tops of larger spatters.
Small-sized spatters produce small, flat, smooth areas within the
texture; large sized spatters produce larger, flattened areas within
the texture.
Both orange peel and knock-down finishes require a spray applicator
to apply splatters of thinned drywall compound to the wall. There
are various types available for purchase or rent, including those
that use compressed air to spray the compound. Other types of applicators
use electric pumps.
Each application device incorporates a hopper into which thinned
drywall compound is placed. Some use larger hoppers that sit on
the floor and feed the solution to a hand-held trigger sprayer.
Others use smaller hoppers attached to the spray gun itself.
Other Texturing Techniques
Another texturing technique is known as “slapbrush/knockdown;”
sometimes also referred to as “palm texture” or “tiger
skin texture.” This technique employs the use of different
types of special texture brushes; round, square, single, or double-headed
– each creating a different effect.
With the exception of popcorn ceiling texturing, most texturing
methods used for ceilings can also be used on walls; for instance,
the stomp brush technique. Texturing compound is thinned to about
the consistency of thick paint, and then applied using a long-nap
paint roller on an extension handle.

The applied mixture is then textured by gently tamping it with
a “stomp brush.” It is important to work quickly before
the compound begins to set. When using a stomp brush, you must rotate
it after each stroke to avoid a repeating pattern from occurring.
With the use of bull-nose corner bead that produces rounded corner
edges, a rustic “old-world” effect can be achieved by
using a trowel to apply a thick coat of drywall compound. Start
at one end of a wall, and then finish with a series of half circles
that overlap down the wall.
Another texture can be obtained by applying a lump of compound
and then tapering it down to the surface. Repeat the process, over-lapping
and working subsequent applications in the same direction, as you
work your way down the wall.
When you use drywall compound to add texture to a wall, use your
imagination to produce different effects. The key is achieving a
consistent finish throughout the project with whatever texture you
develop.
Once texturing has dried completely, apply a primer coat. Follow
by at least 2 coats of paint in the color and type preferred; egg
shell, semi-gloss, or gloss finishes are best choices for washable
walls.
Besides those mentioned above, are other types of wall texturing
techniques; including “sand swirl” and “Spanish
knife.” Application of many types of texturing requires only
a minimum amount of practice to develop the technique adequately.
The main requirement is that application be consistent throughout
the entire area being textured.
Note: spray-on texturing is messy business; all surfaces not
being textured should be covered with plastic sheeting and masked
off. Entryways leading into other areas of the house closed off.
