CORNER INSTALLATION 
All products must be allowed to acclimate; removed from 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 cool, dry product. 
NextStone does not warrant against gapping caused by expansion and contraction.

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.  
Step 2-Set the Castle Rock outside corner piece against the 
corner and down into the starter strip. Use the screw guides 
and place at least 3 screws along the tongue. Place 2 screws in 
the right lap side of the panel where indicated. (Fig. 7) 
Step 3-Attach the panels working in from each corner 
as previously described. (Fig. 8)
