CORNER INSTALLATION 
RANDOM ROCK OUTSIDE CORNER 
Step 2 - Install Random Rock Outside Corners 
1. Corners can be finished with a Ledger (requires miter cutting) or Ledger 
Outside Corner. Top of corner (end with lip on top) should be 1 ⅜" below 
top of flange on top panel. Dry fit if top panel must be cut horizontally.  
2. There are 4 designs. Alternate designs 1,2,3,4 and repeat when continuing 
up the wall. Be sure and alternate “left” and right” pieces to break up  
vertical lines.  
3. Slide the corner piece down onto the starter strip snugly and screw the top 
nailing strip where indicated.  
4.Slide the second corner over the top of the 1st piece and secure as  
described above. 
Step 3 - Using the Converter strip for Random Rock Outside Corner. 
If the job requires 2 outside corners to be finished with no breaks between 
them, when working from the left moving right, the final panel piece must 
be cut and converted to a “male” tongue for proper fit and grout lines to be 
maintained. 
1.Measure the distance from the last panel tongue to the leading edge of the 
outside corner. Subtract ⅜".Cut the panel to this length. 
2.Turn the panel over and measure in from the cut side ⅝". Scribe a line 
down the back. 
3.Set the saw blade for ⅜ “ depth and follow the scribed line (Fig. 1). Use a 
box knife or chisel to complete the dado channel in the back. 
4.Attach the Converter strip using hot glue, Polyurethane adhesive, or super 
glue gel. Make sure the tongue matches in depth and height. (Fig. 2) 
All products must be allowed to acclimate; r emoved fr om boxes and stored flat at the 
installation site for a minimum of 48 hours or until properly acclimated prior to installation. Heat 
and moisture cause expansion. Best results are obtained by installing a cool, dry product. 
NextStone™ does not warrant against gapping caused by expansion and contraction or 
 improper installation.  
Step 1-Start the 1st course from the outside corner of the wall. Place starter 
strip top 2 ¾" above the desired starting height of the wall, recess the strip 
2" from each side of the corner edge.
