3. INSTALLING POLYCURB

With water resistant wallboard already installed, measure distance from left wall to right wall. A) Mark

shower curb 3/16" less than the actual measured distance from wall to wall. B) Using a square, mark all

sides of the shower curb. C) Cut shower curb along desired mark ( see cutting methods ). Test t shower

curb to ensure proper size. D) Turn shower curb upside down and apply generous dabs polymer

modied thinset every 6" to 8" apart the inside are and cavity of both sides of the PolyCurb. E) Apply

generous dabs of thinset to the inside and outside faces of the pan liner over the wood support every 6"

to 8" apart. F) With the 6" side on the outside of the shower and the 5" side on the inside, rmly press

down the shower curb into place until the 6" side touches the suboor. When pressing resistance should

be felt, if there is no resistance remove PolyCurb and apply additional thinset. Recommended thinset

coverage is 90%. G) Once PolyCurb is seated properly level side to side and pitch in towards the shower

drain at 1/8" pitch.
