Installation Guide

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.
