SOLID WOOD PANELING

Solid wood paneling has beenused for centuries in elegant andrustic settings; it has withstoodthe test of time, outlasting everypassing whim of fashion. It is

beautiful when first installed, andstill beautiful after years of use.

Pattern Selection

The eight patterns illustratedin the next column are a few ofthe many patterns available foruse as paneling. P aneling

patterns are often reversible,offering a choice of pattern andsurface finish in a single pattern.WP -4 and WP-11, for example,are V-grooved on one side andsquare edged on the other.

O ther patterns may be smoothsurfaced on one side and sawtextured on the other. However,it is important to remember thatwhen paneling is graded aftermanufacture, it is the patternedside which is inspected.

M ost lumber dealers carry

only a limited selection of panel-ing patterns in stock, but canorder any of the standard pat-terns and some dealers willarrange to have a pattern of yourchoice custom-milled.

Patterns

Note: Numbers and letters under exam-

ples are pattern indications; refer to WWPAs

Standard Patternspublication (G-16), for an

illustrated list of all WWPA patterns.

Preconditioning

Solid wood paneling is anatural material; it responds toclimatic change. Preconditioning,allowing the wood to adjust toon-site atmospheric conditions,

is always desirable prior to instal-lation as it allows the wood tobecome dimensionally stable forthe conditions of its permanentlocation.

K notty grades can have ahigher moisture content than theclear grades. When installed ina heated room, without precondi-tioning, paneling may be expect-ed to shrink. This shrinkage willbe minimized by conditioning thepaneling prior to installation.

Interior construction which

contains moisture-laden materialssuch as concrete, plaster or tex-tured drywall, should be drybefore paneling is delivered orinstalled. M asonry or concretewalls should be waterproofedprior to paneling installation.

It is a good practice to stackall paneling in the room where itwill be installed, with separatorsbetween the layers, for a week toten days prior to installation. Anygrade may pick up moisture intransit or during storage and willneed some preconditioning. Ifpreconditioning is not feasible,use as narrow a width as possi-ble in order to minimize dimen-sional change.

Priming and Sealing

O nce the paneling hasbecome dimensionally stable, itshould be sanded and primed orprefinished prior to installationPrefinishing can minimize objec-tionable lines where joint lines

may appear later on.Wood in kitchens, bathrooms,

basements or other high mois-ture areas, should be protected.A suitable installation in theseareas would include an applica-tion of sealer to front, back, endsand edges of each piece.

INSTALLATION

Over Drywall, Plaster orHardboard

If walls are in moderately good

condition, construction mastic isusually the easiest, fastest way toinstall solid wood paneling overdrywall, plaster, hardboard even old paneling. To apply,follow the adhesive manufactur-ers directions.

To help tighten joints whilegluing, tack through tongue intodrywall or plaster every two tothree feet. Use small nails to holdpaneling in place until masticsets.

Over Framed or MasonryWalls

Nail directly to the framingmembers in both horizontal andvertical applications. Vertical

applications require furring strips48" on center. (See Figures 1and 2.)

NAILING

Tongue and Groove

Tongue and groove panelingin widths up to 8-inches wide isnormally blind nailed through the

tongue. T his eliminates countersinking and filling nail holes andwill result in a smooth, blemishfree surface. B lind nailing is par-ticularly important when a natur-al or stained finish is intended.

Select a finishing nail which islong enough to penetrate block-ing or furring by at least 3/4-inch. O nly one nail per bearingis necessary.

BLIND NAILING

Rustic Patterns

These patterns are difficult toblind nail and should generallybe face nailed. Use 8d finishingnails when face nailing to furring

strips or studs; on other sur-faces, make sure nail is longenough to penetrate stud by atleast 3/4-inch. Panels 6-inchesor less require just one nail perbearing; for 8-inches or wider,use two nails per bearing. Donot nail through the overlapping

joint as this restricts the neces-sary swelling and shrinking ofthe wood.

FACE NAILING

When nailing a board andbatten pattern, fasten the underboard with one 8d nail per bear-ing driven through the center ofthe board. Underboardsshould be spaced approximately1/2"apart. D rive one 10d nail

per bearing through the centerof the batten strip, so that theshank passes between theedges of the underboards.Widewidth boards, if not thor-oughly seasoned, may requiretwo nails per board in theboard and batten sequence.
