  PANEL INSTALLATION 
Metal Starter Strip - Determine at what height above grade level you 
want the panel to sit. Measure up 2 ¾" from this point     
and strike a level line. (Fig. 1) 
Determine which type of wall installation is required.   
1) Paneling the wall using Window Door Trim as termination molding. 
Install Window and Door Trim (WDT) to both ends of the wall. Insert panel 
into starter strip and slide behind WDT. Attach to the wall using the screw 
indicator marks on the top and right end tongues. (Fig. 2) Firmly press the next panel against the 
first panel and repeat working left to right. At the end of the course; cut the right end of the final 
panel to fit behind WDT. Use the drop off from that panel to start the new row behind the left end 
WDT. If necessary, cut some additional length from the off fall pieces on some rows to prevent 
panel ends from lining up vertically. 
2) Paneling a wall using a WDT as a termination molding on the left 
Dry fit the first corner into the starter strip. Secure with screws if necessary. Moving from right to 
left: dry fit panels tightly across the wall. Cut the left end of the final panel behind the Window 
Door Trim or flush to the wall. If not using WDT, remove the dry fit panels and corner piece. 
Panel the wall from left to right. Reattach corner over right panel. Repeat on each row. 
3) Paneling a wall with outside corners on the right and left 
 When there are 2 outside corners with no break in the wall (no window 
or door opening), panels may need be cut if the wall will not 
accommodate full panels. On each course, work from left to right and dry 
fit as described earlier. Decide on each course which panel to cut. Dry fit 
full panels from each end until less than one panel length remains in the 
middle. Measure from the rock edge on the right side of the left panel to 
the left edge of the right panel (Fig. 3). Cut the final panel to this length. 
(Stagger the placement of the cut panels up the wall to avoid verticals line.) After cutting the 
panel, lightly rasp the top of the cut edge to smooth the edge and blend it with the rocks of the next 
panel (fig 4). (Touch up any exposed Polyurethane edges with a NextStone™ Touch Up Paint Kit 
and Caulk) (sold separately) (Fig 5). Slide in the final panel and attach (Fig. 6).  
4) Dry fit panels from left to right 
Cut first panel on the left to fit flush against the left wall. The final panel in the course may need to 
be cut to fit properly flush to the “right” wall. Us the off cut panel to begin the second course at the 
left. Repeat this method to complete your wall.  
Important: Drive the first screw on the right hand side of the panel at a 45 degree angle 
to the left in order to tighten the panel into adjacent the panel, corner or wall. Visit the
