Installation & Assembly

Install Instructions

1. Installation of Inside Corner Reinforcements (J)

A. Flashing Tape Corner Reinforcements go behind the

panels in the back vertical corners for added leak protection.

This tape has been cut to length, matching the height of the

panels of your kit.

B. Apply a bead of adhesive onto both walls about 3/4 inch

away from the corner. Fold the ashing tape at the center

crease with the print side together, then press the tape into

the corner using a taping or putty type blade. Using the same

blade, atten out the tape to create a at, smooth inside cor-

ner. Wipe away any excess adhesive.

2. Installation of Back Wall Panel (A)

A. The back panel must be t to both the left and right corners,

and to the tub or shower base. Keep in mind that walls may

not be square or plumb, so you will want to measure width of

the alcove at both the bottom and top of the alcove prior to

trimming panel. (See TIP on right and below for a technique

for achieving good fit measurements.) Trim the panel to

size with a utility knife, jigsaw, or power plane and dry t

until a tight t is achieved.

B. When satised with the t, peel protective masking back

from the edges of the panel (approx. 4") and clean burs from any

rough edges. Apply adhesive in lines or dollops to the back of

the panel in a pattern every 4 to 6 inches. Use approximately

one 10oz tube per 12 square feet following the adhesive

directions on the tube. Push the panel in place, lightly

pounding to achieve good bond.

NOTE: It is not necessary to cut the top edges of panels to be level, as

they will be covered by trim moldings.

TIP: Draw a vertical plumb line directly on the middle of the

sheetrock from top to bottom of wall. Now draw a horizontal

level line crossing the plumb line about halfway up the wall.

Record measurements left from the vertical line to corner at top,

middle and bottom (L1, L2, L3), then right from the vertical line to

corner (R1, R2, R3.) Now record measurements down from the

horizontal line to the tub (D1, D2, D3.) Transfer these measure-

ments to your back wall panel (A). These 9 measurements will

account for out of plumb walls AND out of level tubs!
