Installation Guide
RUSTIC SHIPLAP 
INSTALLATION INSTRUCTIONS
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  if  the  product  doesn't  
adjust  to  room  conditions  prior  to  
installation.  As  wood  dries,  a  slight 
joint may open up. It is recommended 
to paint the surface behind the wood a 
dark color.
Nail  directly  to  the  wall  framing  when 
installing  in  a  horizontal  orientation.  
For  applications  where  vertical  
orientation  is  desired,  full-length  
furring  strips  must  be  installed  24  
inches  on  center.  Use  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.
Nail  through  the  top  flange.  A  second 
nail  should  be  placed  through  the  
bottom  face  of  the  board,  approximately  
1" from the bottom edge (ensuring not 
to nail through overlapping pieces).
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,  be  sure  to  follow  the  
manufacturers instructions.  To  make  sure 
you  have  a  tight  joint  when  applying 
adhesive,  use  small  nails  to tack  up 
and  hold  the  shiplap  in  place  on  the 
drywall or plaster while adhesive sets. 
Apply tack nails every two or three feet.
DO NOT NAIL THROUGH 
OVERLAPPING PIECES
IT IS RECOMMENDED THAT A 
FINISH BLADE OR FINE TOOTH 
SAW BE USED WHEN CUTTING 
TO REDUCE SPLINTERING.
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.
15- or 16-gauge trim 
nails. Nail 1" from 
bottom of siding 
board (to clear 
top of preceding 
siding layer).
