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 a 90° corner but it works equally well on 90° corners. 
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). In this way 
the individual “rocks” will wrap 
around the corner. You will have to 
lay out the first course so that the last 
panel that will be 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 a joint as possible. 
For example, if you were installing NextStone on a 7' wide wall with a 90° corner, the 
second panel would make the corner. You would cut the panel on a 45° miter so that it 
was 3' measured on the short side and install. You would then cut the drop-off piece (1') 
at 45° and install it on the other side of the corner. Be sure you stagger each course so 
that the corner cut does not fall at the same place on the panel used to make the corner. 
Step 4 
In exterior applications run a bead of caulk along the joint where the panels butt 
together. This can be concealed with touch-up paint if you wish. 
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 coated 
with touch-up paint. In addition, you may wish to conceal the caulk line by painting 
with touch-up paint.
