RANDOM ROCK OUTSIDE CORNER, Cont. 
5.After curing, fill any gaps between the panel face and converter piece with NextStone™ grout. Fill 
from the back side to insure a solid grout line is achieved (Fig. 3). Use putty knife along rock edges 
to achieve a smooth surface. After it becomes tacky, use touch up kit to paint the exposed edges and 
grout (Fig. 4). 
6.Attach the piece as if it were a full panel (Fig. 5). 
If terminating the run on the right side with other trim pieces, follow the instructions below 
For 2 facing Outside Corners follow Section 3 on previous page.  
1 - Starting from the left, take a full panel and attach the bottom tongue into the 
starter strip groove, lock in place, and slide the panel left behind the accessory 
piece, see back. Using the screw guide points, screw through the substrate and 
into a stud when practical, with a minimum of 6 screws per panel and a screw no 
less than 1" from each end of the tongue as well as in the bottom right corner of 
the tongue. Working left to right continue installing panels in the bottom course  
making sure each panel is properly set in the starter strip. For the last panel in the 
course, measure from the edge of the grout line to the accessory piece, add 1" If 
sliding behind a trim piece, cut the last piece until the panel is locked in the  
starter strip, then slide panel back to the left until the shiplap sides are joined. 
(Check for level.) 
2 - Install the remaining courses by beginning the course from the left with full 
panels. The stagger is built in with the corner pieces. Slide the panel down 
over the tongue of the first course. Install remaining panels in the course, end 
row as before, and check for level. Align panels using the alignment mark at 
each side on the tongue. Do not align panels using the top of the tongue. The  
remaining courses are installed the same way. Stagger the NextStone™ butt 
joints so that no two courses are aligned vertically unless separated by 
three courses.  (All exposed edges should be painted and caulked behind tr im pieces. ) 
3 - Cut panels around fixtures and other wall protrusions (hose bibs, electrical boxes, dryer vents, etc) 
to accommodate NextStone™ Mounting Blocks. See Install instructions on page 25 or visit 
NextStone™.com for details on how to cut panels and install the mounting blocks.
