CORNER INSTALLATION
SANDSTONE FLUSH OUTSIDE CORNER
Step 1
Install moisture barrier.
Flush mounted corners allow possible moisture
infiltration between the panel and the corner, therefore, a
moisture barrier may be required behind the panels and corner
extending a minimum of 4" from either side of the corner. A
self-adhering flashing membrane such as Grace Vycor® is
recommended.
Step 2
Flush mounted outside corners are available in 4' heights. The
placement of the corners will depend on how the top of the
corner is terminated. For applications over 48" in height, the
corner pieces are stackable with the final corner cut to the
required height. For wainscot applications, the corner can be
capped with a ledger attached to the tongue of the top panel
and cut with a compound miter at a 45° angle, or a Ledger
Outside Corner. In this application the top of the corner should
be placed 2" below the top of the tongue on the top panel.
Step 3
The corner has screw guides or dimples to help position the
screws using the correct angle. There are also screw guides
along the sides. All screws are installed at an angle and at a
location where they will be concealed. Install two screws
through the top and at least 4 on each side. Good quality
exterior screws, #6 or #8 x 2 ½" are recommended.
Step 4
Install the remaining accessories and finish the panels. The
joints between the panels and the corner must be caulked using
a good quality caulk or textured grout to make a water-tight
installation. Installation instructions are included in the box of
panels or go to www.NextStone™.com for more details.
