10) SUBSEQUENT COURSES (WORKING YOUR WAY UP THE WALL)
Remember, install outside corners on the course you are working before installing panels.
Alternate left and right corner pairs as you work your way up the wall. This helps prevent
the alignment of vertical seams and maintain the necessary 6 inch offset (See Figure 3).
Stair Stepping
Corners and flats can be built up in a stair step fashion once the initial course of stone has
been installed (See Figure 4). This technique improves efficiency, reduces installation
time, and helps hide cut edges in inconspicuous areas.
Set a starting edge from which you will work right or left from.
• In the case of an outside corner, install the full outside corner (both sides), up to 8
courses at a time following the directions for installing outside corners. Never install a
corner or panel unless there is a stone or transition below it.
• In the case of trim, the trim will set the edge. Step flash the edge
s
as you install the flat
panels. Cut between 4 and 7 inches off the first flat panel on alternating courses to establish
good seam offsets. Cut the stone, per the cutting instructions. If trim is not thick enough to cover the edge
of the stone, you may want to grind down the panel edge to meet the trim edge or install a vertical drip edge
to provide a finished look. Ideally, the trim should be equal to or thicker than the panel edge.
Completing courses
When completing courses, cutting factory edges is unavoidable. However, avoiding cut edges in high visibility
areas and near focal points is not difficult. Care should be taken to plan accordingly.
The following addresses three common installation scenarios and how to make unsightly cut edges less visible,
if not invisible:
❖ If installing on a wall with two outside corners, pick a corner and work across to the other corner. Consider
sight lines as you will likely have a cut edge to complete each course. You can cut the corners or the panels
before the corners.
❖ If installing on a wall with one outside corner and one inside corner, start at the outside corner and work
toward the inside corner. All cut edges should be close to and directed toward an inside corner.
❖ If installing on a wall between vertical trim where the trim will hide all cut edges; start at one end, and work
toward the other end. If the trim is thinner than the thickest stones on the panels, work from the trim in a
stair step manor toward the desired location of the cut stone(s)..
Continue working up the wall as previously instructed, ensuring all panels are properly installed.

11) SUPPLEMENTAL FLASHING & TRANSITIONS
Refer to - for this section.
Step Flashing Defined
Silvermine’s patented integrated flashing system is designed to form a shingle-like pattern, much like that of a
shingled roof. In the case of roofs, continuous flashing against a sidewall is one way to install a roof, but it’s
not the correct way. It may seem as if a single piece of flashing would offer more protection than many pieces
of step flashing, but it doesn’t work that way. Once even a small section of single flashing or shingling is
pierced, a leak will occur. Each additional rain adds water, and before you know it, you’ve got rotted wood. In
the long run step flashing will do a better job of preventing water leaks as step flashing redirects water back
