Instructions / Assembly

Install shiplap horizontally or vertically. For horizontal
applications, start with the bottom course and work
up with overlap pointing downward. Do not nail
through overlaps. Shiplap siding is tight-fitting,
so butt the courses up close.

SHIPLAP INSTALLATION INSTRUCTIONS
Watch installation video prior to installation at
ufpEDGE.com/Timeless
Allow the wood to acclimate for several days prior to installation
in the room in which it will be installed. Variances in temperature
and moisture between the storage and application areas have
a negative effect on the finished appearance.
Installing Trim (Optional)
Prior to installation, determine if 1x4 Timeless trim boards
will be purchased and installed to frame your project. Timeless
trim can be installed before or after shiplap installation,
depending on the desired look (refer to installation video link
above). If installing trim, fasten each board by applying a bead
of fast grab construction adhesive and drive 16-gauge nails
into the face. Each fastener should penetrate into a wall stud
or wood furring strip.
Installing Interlocking Shiplap
Fasten shiplap directly to the wall framing when installing in
a horizontal orientation. Always start horizontal installation at
the bottom of a wall or the edge of a ceiling. The interlocking
profile allows for each board to fit snuggly into each other. For
applications where vertical orientation is desired, full-length
furring strips must be installed 24 inches on center when
fastening shiplap. Fasten shiplap using standard or painted
trim nails (15 or 16 gauge). Fastener length should be long
enough for 1 1/4”-1 1/2” of penetration into solid wood. Some
boards may need to be trimmed lengthwise to fit the final
dimension of your wall or ceiling. Use a table saw or circular
saw to trim lengthwise. With prepainted shiplap, apply a
bead of fast grab adhesive to the bottom of the board. Drive
fastener through the top flange of the board and into a stud to
secure. This will minimize the number of nail holes that need
to be filled.
When installing shiplap over plaster or hardboard, the walls
need to be in moderately good condition. Construction adhesive
is usually the easiest and fastest way to install wood shiplap
over drywall, plaster, hardboard and even old shiplap. When
applying adhesive, follow the manufacturer’s instructions. To
make sure you have a tight joint when applying adhesive to
drywall or plaster, use trim nails to hold the shiplap in place
while the adhesive sets. Apply trim nails in the shiplap tongue
every 24 inches.
