MORTAR BED SETTING OF TILE OR STONE
OVER INFLOORBOARD™:
Infloorboard™ shall be installed over a
wooden subfloor, complying with “General
Infloorboard™ Installation Requirements
For All Flooring Over Wood Subfloor”. In
addition, the following specific cautions
and instructions shall be followed:
When installing masonry, tile and stone,
backer board shall be used over
Infloorboard™. A conventional mortar
bed shall then be used. In the kitchen,
bath, laundry or any other area where
water may be present, a water sealant (i.e.
Nobleseal) shall be used. Maintain 2” mini-
mum tubing clearance when screwing
backer board down. Refer to the complete
installation manual for further instructions
on the installation of the Infloorboard™
system.
Traditional mortar set tile or stone for areas
unlikely to be subject to moisture
Notes On Sealing
The aluminum layer on the top of
each Infloorboard™ is highly water
resistant. Thus a significant
degree of moisture protection can
be given to the board simply by
using silicon sealant as a caulk
between the boards. Properly
applied, this will profoundly
reduce the likelihood of water
transmission into the boards. This
is not a substitute for recommend-
ed installation methods in wet
areas.
INSTALLER’S CAUTION:
Do not omit the backerboard layer. Do not set
directly to Infloorboard™, the aluminum will
not provide a good bond. Do not install crack
isolation membranes directly to
Infloorboard™, they will not get a good bond
and many of them use materials that are
incompatible for contact with Pex pipe.
