 SLATESTONE PANEL INSTALLATION, Cont. 
Paneling a wall with outside corners on the right and left.  
Working from the left outside corner (OC), seat the 1st panel against the OC and down 
against the starter strip, continue as described in section 1. Cut the right OC so there is a 
straight rock edge and attach. Measure the last piece on the row and cut this panel 
straight to fit snugly against the OC. Caulk the joint if necessary and use touch up paint. 
Work the right corner from left to right 
as described in section 1. Work the left 
OC as described in section 2.  
Option 2: (More skill required) 
Working from the left outside corner 
(OC), seat the 1st panel against the OC 
and down against the starter strip, 
continue as described in section 1. 
Place the right OC in place for 
measurement. Place a weather barrier 
cleat such as black tar paper, Tyvek or the equivalent to the substrate behind the joint. 
Measure the last piece on the row and cut this panel using the âTâ design for the male 
tongue. Use an existing panel as a template. A carpenter knife and sabre saw is neces-
sary. Attach against the OC and secure both pieces. Caulk the joint if necessary and use 
touch up paint. Work the right corner from left to right as described in section 1. Work 
the left OC as described in section 2.  
Slatestone panels have 8 unique panel configurations with a number, 1 through 8, 
molded into the back of the panel. Avoid racking the panels by placing like numbered 
panels next to or on top of each other.  
The illustration below shows a random installation using drops from the  
previous course to start each new course. If there are no drops, randomly cut the 
starting panel to length.
