Installation of Inside Corner Trim
1.  Inside Corner Trims can be used to hide gaps or poor 
cuts where two panels meet in a corner. Install Inside Corner 
Trims AFTER the FlexStone wall panels and edge trims and 
corner shelf are installed. Be sure to peel away protective 
masking from the wall panels efore installing the Inside
Corner Trim.
2.  Measure from the tub or shower base to the bottom of 
the horizontal edge trims of the bath kit. Cut the Inside Cor-
ner Trim to proper length. If a corner shelf is installed in this 
corner, divide the Inside Corner Trim into sections to run from 
the tub or shower base up to the bottom of the corner shelf, 
and from the top of the corner shelf up to the edge trims. 
3.  Peel away protective masking from the trim, apply con-
struction adhesive to the back of each ange of the trim, 
keeping the adhesive away from the edges of each ange (to 
avoid adhesive squeezing out the edges).
4.  Secure in place, and hold with painter’s tape while the 
adhesive cures.
5.  Seal all edge joints with Performance Pro 100% Silicone, 
as with the rest of the surround.
