Installation Guide

POLYNICHE INSTALLATION

1) Find desired location to install PolyNiche, make

sure the location will be clear of obstacles once

wall is cut open so PolyNiche will t properly. Place

PolyNiche at against the wall where cutout is to

be made, with open side facing the wallboard.

Place a small level on the top side of PolyNiche to

ensure a level and plumb cut. Next, trace the 4

outer perimeter sides of PolyNiche, then remove it

from the wall.

2) Cut along the lines that were traced from

step 1. Use a keyhole, hand or jig saw to make

the cut into the wallboard. Once the wallboard

is cut, remove the loose center section.

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

location must be determined according to stud location, and wallboard must be installed.

MATERIALS: Non-corrosive construction screws, 1”x4” wood strips and mesh tape.

APPLICATION: The 1"x4" wood strips used may be pressure treated. All thinset used during installation of

PolyNiche must be polymer modied thinset.

CURING: There is no cure time limitation with the wood strips. Once PolyNiche is installed the mesh tape

can be applied along with the modied thinset. Waterproof Membrane may then be applied over cured mesh

tape and modied thinset.

POLYNICHE INSTALLATION 3. Cut 2 wood supports to be installed vertically in the opening made from step 2. Cut wood supports 4 inches longer than the vertical opening measurement. Once cut, place the wood supports on the backside of the wallboard centered in the opening, with half of the wood support exposed to the opening. Secure wood supports in the wallboard using non-corrosive screws, which are to be approx 6” apart on both vertical sides of the opening. 4.

POLYNICHE INSTALLATION 6. Remove any debris and ensure PolyNiche and wallboard are clean. Apply drywall mesh tape over all seams where PolyNiche meets the wallboard. Secure mesh tape in place by pressing it in place with a trowel. 7. Apply a skim coat of Polymer Modified Thinset over the mesh tape to secure the joint between PolyNiche, and the wallboard. Flash out thinset if nessecary. Once the thinset is cured, a coat of waterproof membrane may be rolled or brush on.
