• FASTENER SPECIFICATIONS - For aluminum flashing, use only fasteners that meet the
specifications below and drive them 90
o
to face of structure (See Figure 2)
o Head Types: Pancake Head, Modified
Truss Wafer Head, Washer Head
o Size: #10x1-1/2” or longer
o Head size: 12mm or larger
o Material: Quality Multiple-Coated Steel
or stainless steel
o Threads/Inch: 12 or less, fully threaded
o Head : shaft angle: 90° shaft.
• Using any fasteners that do not meet Silvermine’s specifications or driving any fastener at an angle
can damage the flashing and result in water damage and/or reduced performance in wind conditions.
• Install fasteners at least 1 inch above the top edge of the panel to avoid water penetration. Drive fastener
flush to the flashing/substrate layer. DO NOT overdrive fasteners as this can damage flashing.
• Each panel should have at least 1 fastener driven into a stud. Panels longer than 16 inches should have at
least 3 fasteners and panels less than 16 inches should have at least 2 fasteners. In the rare cases where no
fasteners can be driven into a stud, supplemental gluing as described above to aluminum flashing fastened to
at least one stud is required. Additionally, apply a ¼ inch thick dashed line of adhesive along the top of the
stone(s) the piece will be set on, leaving 2 inch spaces between “dashes” to allow water to escape.
Fastening Modified
o
Panels
• “Modified panels” are Silvermine panels where the integrated flashing has been removed.
• Modified panels above four feet must be “face-fastened” together with the use of construction adhesive.
This ensures good contact between the panel and the bonding surface while construction adhesive is curing.
• As a rule, one fastener every 10 inches (horizontal length) of a modified panel will be enough to supplement
the adhesive.
• Install face-fasteners as follows:
o DO NOT USE A HAMMER DRILL for either drilling pilot & counter sink holes or driving face
fasteners as the force may crack the panels.
o Drill a pilot holes through the stone panel using a 1/8 inch masonry bit.
o Drill countersinking holes 1/2 inch in the same locations using a 5/16 inch masonry bit, making sure to
leave a minimum of 1/2 inch of stone behind the head of the screw.
o Apply a 3/8 inch thick, quarter sized dollops of construction adhesive (every 6 to 8 inches) to the
aluminum flashing the panel will cover 2 to 4 inches above the top edge of the panel beneath.
o Apply a 1/4 inch thick dashed line of adhesive along the horizontal and vertical edges of the panels that
will adjoin the modified piece leaving 2 inches between “dashes” to allow water to escape.
o Install modified panel and press into adhesive to assure complete contact.
o Drive screw(s) through the pre-drilled panel and into the substrate. Do not over-drive the screw as you
will crack the panel. Use only enough torque to pull the panel into the adhesive and to maintain contact
while adhesive cures.
o Use a matching color exterior grade sanded caulk to cover the screw head and fill the counter sink hole.
• Caution: Fasteners may crack a panel if installed in the simulated mortar joints. It is best to select a
thicker area of the panel to drill out the holes for the face fastening screws. Holes from drilling are easier to
conceal in darker areas of the stone.
