Installation Guide

For complete and up-to-date installation and warranty information please visit
www.armadillodeck.com. All ends and ripped/exposed armadillo boards must be sealed using
Armadillo End Board Sealer so as not to void warranty. Proof of purchase is required.
STEP 1 SOLID AND GROOVED
Add a support joist to the outside or inside of the outer joists. Insert the Armadillo ashing so the
shorter edge rests over the house ledger wood board and the longer plastic edge is inserted behind the
house siding. Add notches in the Armadillo ashing to clear wood joists as needed. Add an additional
support joist to the outer edge (prevents stringer movement). For longer spans/runs of decking please
add additional support blocks throughout substructure, preventing twisting and adding rigidity.
STEP 2 SOLID AND GROOVED
Start at the edge away from the house. Pre-drill clearance holes starting 1” in from board end and
1” from outer edge of deck board. Screw down the rst deck board using the pre-drilled holes. Use
recommended trim head screws. Drill screws in perpendicular, not at an angle. DO NOT OVERDRIVE.
STEP 3 GROOVED
Place an Armadillo deck clip in the groove of the Armadillo deck board centered over each joist and
fasten screw with the corresponding bit. DO NOT OVERDRIVE. When installing fascia to cover the
ends of the boards, screws are not required around the outside deck perimeter.
STEP 4 SOLID AND GROOVED
Slide your next deck board onto the exposed Armadillo deck clips or tap a solid board rmly against
a 1/4” spacing tool and use recommended trim head screws with pre-drilled holes for thread head
clearance. Add the next row of Armadillo deck clips as shown in Step 3 or reset your 1/4” spacer.
Continue to measure the distance to the home and adjust accordingly so the last board doesn’t have
to be trimmed lengthwise at an angle.
STEP 5 SOLID AND GROOVED
When butt joints are used allow 1/16” gap between board ends. We recommend picture framing and
using a transition board to avoid butt joints.
STAIR INSTALLATION
Stair stringers should be placed 12” on center. Face screw boards on stair stringers. Use solid boards
only. A 1/16” minimum edge gap is required between stair treads.

ATTENTION: Obtain building permits before building. • Store flat and provide support every 2 ft. • Keep covered prior to install. • Joist spacing for
residential is 16" on center and 12" on center for commercial. • Armadillo boards can NOT be installed directly on old deck boards or cement. Please
reference our screw and hidden fastener guide at www.armadillodeck.com. Do not over tighten fasteners. Screw heads MUST be flush with the top of the
deck board. DO NOT OVERDRIVE SCREWS. Install grooved boards with Armadillo or Turboclip hidden fasteners, using other fasteners will void warranty.
Improper face screwing increases board splitting. We recommend using Armadillo or Turboclip hidden fasteners to avoid this issue.
