ALTERNATIVE FASTENING OPTION: 
ATTACHING TRIM AS BATTEN STRIPS
•  In cases where trim/batten strips 
are fastened just into the structural 
sheathing, attachment will require 
additional support from a construction 
adhesive. 
•  First, secure the trim to the structure 
while the construction adhesive 
completely cures, using hot-dipped 
galvanized ring-shanked nails no smaller 
than 0.091 inch shank diameter. 
•  Second, use an exterior grade 
construction adhesive that meets the 
following specications.
Construction Adhesive Specications:
•  Minimum bond strength: 300 psi
•  Minimum application temperature: 40° F
•  Paintable grade
INSTALLATION 
•  When attaching trim as batten strips, 
follow the Fastening Instructions section 
in this document.
•  Exception: When using trim less than 3 
inches wide as battens, apply only one 
nail per width, a maximum of every 36 
inches vertically.
•  When batten strips are applied over 
panel siding at vertical joints, sealant is 
not required.
•  When batten strips are applied to walls 
with horizontal panel joints, do not run 
battens over the panel joint and ashing. 
Terminate the trim battens above and 
below the horizontal panel joint to allow 
for  proper  spacing  and  ashing. 
(See 
diagrams 10a and 10b)
•  When batten strips are applied to walls 
with horizontal band boards be sure to 
properly ash above and below the band 
board. Leave a minimum 3/8 inch space 
between the ends of the batten strips and 
the band board. Prime and paint all cut 
ends and  exposed substrate. Z-ashing 
installed below the band board must 
cover the top ends of the batten strips 
below.
