Installation Instructions

Countertop
Application
Determine whether floor is
level by measuring distance
to desired tile height on both
sides of area to be tiled. If
there is a dierence (i.e., the
floor is lower on one side), lay
one vertical row of tile from
desired tile height to low point
of floor. Ax tiles with tile-
setting materials. Use this first
row as a guide to keep tiles
and grout lines level and even
throughout installation.
If new flooring will be
installed, allow for thickness
of new flooring where the wall
meets the floor.
Installing Ceramic Tile
Always follow current ANSI
specifications and TCNA
guidelines for installing tile.
Apply tile-setting material
to tile backerboard with
notched trowel; key in mortar
or adhesive with smooth side
of trowel to prime USG
Fiberock surface first, then
comb out mortar or adhesive
in straight parallel rows, hold
trowel at min. 45º angle to
maintain uniform thickness.
Working a small area at a
time, set tile with a slight
twisting motion and press into
place. Keep tiles aligned so
joints are straight and uniform.
Use tile spacers if desired. If
excess adhesive squeezes from
under tile, remove before it
dries.
Cover plywood base with USG
Durock
™
tile membrane, 15 lb.
felt or 4 mil polyethylene and
attach with 1/4" galvanized
staple.
Position
Fit ends and edges of panels
closely, but not forced
together. Stagger panel joints
from plywood base joints.
Fasten
Space fasteners 8" o.c. around
the perimeter and in the field
of the board.
Joining
Fill joints with latex-fortified
mortar or Type 1 organic
adhesive and immediately
embed alkali-resistant,
fiberglass mesh joint tape.
Finish
Install tile.
NOTE: Because cement board
fasteners may protrude
through the plywood base
when 1/4" cement board is
used, 1/2" or 5/8" cement
board is preferred in this
application.
