Installation Guide

POLYCURB INSTALLATION

1) CUT AND INSTALL

1"X4" WOOD SUPPORT

Measure distance from left stud wall to right stud

wall. Cut pressure treated wood support 1/4" less

than the actual measured distance. Install wood

support using angle brackets at either end

securing wood support to stud wall.

* If installing a wood support larger than 60" install an additional angle

bracket in the center attaching the wood support to the suboor.

** If installing a 2 or 3 sided curb design install an additional angle

bracket near each corner attaching the wood support to the suboor.

2) SHOWER PAN LINER

The shower pan liner should be installed in

accordance with all local building and

plumbing codes. Pan liner fold slack can be

secured to the stud wall or can be secured to

the 1"x4" wood support (Smith system

recommended - see Diagram). Secure pan

liner with 1/2" screws on top and outside

edges of wood support. DO NOT INSTALL

SCEWS ON INSIDE EDGE OF WOOD

SUPPORT TO SECURE PAN LINER.

PREPARATION: To ensure proper installation clear work area of all debris, dirt, and dust. When applying

thinset to install shower curb wash work area with a clean oil free sponge and towel dry.

CUTTING: PolyCurb can be cut with any serrated blade such as a circular saw, miter saw, hand saw or

serrated knife.

APPLICATION: The 1"x4" wood support used must be pressure treated. All thinset used during

installation of PolyCurb must be polymer modied thinset.

CURING: There is no cure time limitation with the wood support or shower pan liner portions of the

installation. The PolyCurb can be set immediately after wood support is installed, and where required the

mesh tape can be applied with along with the modied thinset. The shower oor mud bed may be installed

instantly after the PolyCurb installation. Allow PolyCurb 12 hours cure time before applying nish tile and/or

waterproof membrane.

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 fit shower curb to ensure proper size.

4. FINISHING Once the curb is properly installed A) apply mesh tape to ALL SIDES. Sides include: bottom of 6" side to the subfloor, PolyCurb ends to the walls on top, 5" and 6" sides. Once the shower floor mud bed is cured, the bottom of the 5" side can be taped. Mesh tape should be placed half on PolyCurb and half on the substrate. B) Apply polymer modified thinset to mesh tape for a permanent bond. Once cured, the PolyCurb is ready to be tiled. A B The Smithson Company, Inc. 561.312.
