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

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).
