PRODUCT USES
External wall cladding as a substrate for JetCoat or other texture systems
BASIC COMPOSITION
Environment-friendly magnesium cement
JOINING REQUIREMENTS
JetBoard panels are fastened at abutting board edges and optionally covered by PVC or metal joiners, battens, or with a compatible caulk.
FASTENER SIZE AND SPACING
-
* Installation to conventional wood frame construction in most locations: minimum 4d common nails spaced 8" o.c. at panel adges and intermediate framing members spaced up to 24" on center.
-
-
* Installation to conventional 20ga metal frame construction in most locations: minimum No. 8-18 x 0.323" HD x 1" long ribbed bugle screws spaced 6" o.c. at panel edges and intermediate framing members spaced up to 24" on center.

FASTENING
JetBoard panels can be hand nailed or fastened with a pneumatic tool. Set your air pressure so that the fastener is driven flush with the panel surface. The use of a flush mount attachment is recommended on pneumatic tools to help control the depth that the nail is driven.
FASTENER REQUIREMENTS
-
* Position fasteners a minimum of 3/8" from edges.
-
* Drive fasteners perpendicular to siding and framing.
-
* Fastener heads should fit flush against soffit (no air space).
-
* Do not over-drive nail heads or drive nails at an angle.
-
* If nail is countersunk, caulk nail hole and add a nail.
FASTENERS
Nails and screws must be corrosion-resistant. Nails complying with ASTM F-1667 must be corrosion-resistant, galvanized, or stainless steel. Electro-galvanized nails may be used but may exhibit premature corrosion. JetBoard recommends the use of quality, hot-dipped galvanized nails. Screw fasteners for the installation of JetBoard shall be corrosion-resistant.

FINISHING
Patching
Dents and chips can be filled with a cementitious patching compound or an elasto-meric filler.
Caulking
A high quality, paintable caulk is recommended. For best results, use caulks that comply with either ASTM C834 or ASTM C920. Caulking should be applied in accordance with caulking manufacturers' written instructions.
-
* Leave 1/8" gap at trim for caulk
-
* Caulking at butt joints is optional
Painting
For best results, JetBoard should be primed first and then painted with a 100%
acrylic topcoat(s). Multiple topcoats will extend the life of the painted
surface and the board.
