Installation Guide
NOTE: Corner shelf includes a folding-triangle metal bracket with 
screw holes which is designed to mount directly to the FlexStone wall 
panels. Be sure to peel away protective masking from the installation 
area before securing the bracket.
5.  Installation of Corner Shelf (I)
A.  Position corner shelf bracket in desired corner at desired 
height. Use a level to mark level lines in pencil. Adjust the
alignment to include a slight forward slope for water runo.
B.  Using drywall screws or other coarse-thread screws, 
fasten each side of the bracket through the FlexStone panels 
and the sheetrock. 
C.  Fold bracket and complete triangle by bending the tab 
over to secure bracket. Dry t the corner shelf material over 
the bracket. If corner is out of square, trim one side of shelf 
to achieve a tight t. 
D.  Peel back protective masking from edges of shelf, 
apply adhesive to top and bottom of bracket and place 
FlexStone material over bracket like a clamshell. Clamp 
until dry (24 hours).
6.  Sealing with Silicone
A.  If you desire to paint the walls now or in the future, use 
paintable latex caulk where trim moldings meet sheetrock. 
Use wet nger or caulk tool to shape the latex caulk to a 
nice nish.  
B.  Using denatured alcohol, clean and prime all joints in the 
surround, including vertical and horizontal joints where panel 
meets tub, panel meets panel, or trim meets panel. Clean 
any oils, greases, or adhesive residues from these joints.
C.  Seal all joints in your surround with 100% silicone. Our 
installation kit has color-matched translucent silicone, tinted 
to complement your selected FlexStone color. Apply a ne 
bead of silicone to all joints. Use wet nger or caulk tool to 
shape the silicone to a nice nish. Follow any directions on 
sealant tube.
