 SANDSTONE WINDOW AND DOOR TRIM 
Step 1 
Sandstone Window and Door Trim can be used as a utility 
trim to terminate sections of NextStone™ panels, as a cap, 
or as a trim piece around windows and doors. For most 
applications, Sandstone Window and Door Trim must be 
installed prior to the panels.  
Step 2 
Measure the total height of the wall before the Ledger 
attachment to determine quantity and length/height of the 
Window and Door Trim.  
Step 3 
Use a level when placing Window and Door Trim. Install 
with dado away from the frame. Screw at a 45° angle 
through the top of the piece and down along the inside 
edge, making sure to attach securely to the underlying 
substrate. To miter for use with ledger, cut the top of the 
piece on a 15°angle, with the long side of the angle against 
the wall. 
Step 4 
If desired, a wood rasp can be used to round edges of the door/window trim to provide a 
more realistic look. Touch-up paint can be applied to the area formed with the rasp. 
Always use a finished end to start and terminate a section of door window trim. Cut 
ends can be butted tight and concealed with touch-up paint and caulk. End Ledger with a 
factory finished end. (See ledger installation). 
TRIM INSTALLATION 
All products must be allowed to acclimate; removed fr om 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.
