MITERED CORNER 
MITERED OUTSIDE CORNER  
Step 1 
In  some  situations  the  installer  may  prefer  to  do  a  miter  cut  at  the  corner  rather 
than use the outside corner accessory pieces. This application is most common when 
the corner is not 90°. Mitering can be used for any corner applications.  
Step 2 
In  exterior  applications  the  corner 
must first be  made water-tight by 
installing a moisture barrier prior to 
installing the NextStone™ panels. 
Step 3 
Both  sides  of  the  corner  should  be 
cut from the same panel or another 
panel of the same configuration (the 
number on  the  back  is  the same). 
This way, the individual “rocks” will 
wrap  around  the  corner.    (You  will 
have  to  lay  out  the  first  course  so 
that the last panel used to form the 
corner  is  at  least  8"  too  long.)    Cut 
the  panel  at  the  appropriate  angle 
(one half of the angle of the corner) 
and  install  as  previously  explained. 
Next, cut the drop at the same angle 
and install the other side of the corner making as tight of a joint as possible.  For 
example, if installing NextStone™ on a 7' wide wall with a 90° corner,  the second 
panel  would  make  the  corner.    Cut  the  panel  on  a  45°  miter  so  that  it  was  3' 
measured on the short side and install. Then cut the drop-off piece (1')  at 45° and 
install it on the other side of the corner.  Stagger each course so that the corner cut 
does not fall at the same place on the panel used to make the corner. Secure joint 
using Polyurethane Adhesive. 
Step 4 
Run  a  bead  of  NextStone™  Grout  along  the  joint  where  the  panels  butt  together. 
Concealed with touch-up paint. 
Step 5 
There is variation in thickness within each individual “rock”, therefore, there will be 
small  areas  of  exposed  polyurethane  where  the  panels  were  cut  which  must  be 
rasped down and coated with touch-up paint.
