allowed to acclimate to the temperature
and humidity of the room. Leave the closed
package in a horizontal position for at least
48 hours prior to installation. Preferred
temperature should be 65° - 85°F. If ooring
is exposed to temperatures less than 40°F
for more than one hour, an additional 4 hours
of acclimation is required at the preferred
temperature.
• Install the product only after the jobsite has
been cleaned and cleared of other trade
apparatus that may damage a nished tile
installation.
NOTICE
This product is not recommended or
warrantied for: outdoor installations, showers,
counter tops, walls and ceilings etc.
II. SUBFLOOR INFORMATION
• Careful and correct preparation of the
suboor is a major part of a satisfactory
installation. Roughness or unevenness of the
suboor will telegraph through the new oor
covering, resulting in an unsightly surface and
excessive wear on high spots. The atness of
wood suboors or underlayment’s must not
exceed on variation of 1/4” in 10 feet (1/2cm
in 3 meters).
• All suboor/underlayment patching must be
done with a non-shrinking, water-resistant
Portland cement patching compound.
• Never install BaseCORE over residual
asphalt-type (cut back) adhesive. It can bleed
through the new oor covering. Residual
asphalt type adhesive must be completely
removed and covered with underlayment.
• Floor must be clean, smooth, at, and
dry. Remove all foreign substances such
as wax, grease, dirt, construction marks
and contaminants, and any substance or
chemical that would interfere with a good
bond. Avoid using sweeping compounds.
Do not install over substrates that have been
chemically cleaned.
UNDERFLOOR HEATING NOTICE
Underoor heating is possible with
warm water heating systems.
For other underoor heating
systems/mats, check with the
underoor heating manufacturer.
Before tting, please conrm suitability
and their guarantee. The temperature
of the oor surface must not exceed
85°F (29.44°C) at any point.
• Before installing over newly constructed
radiant heat systems, operate the system
at maximum capacity to force any residual
moisture from the cementitious topping of
the radiant heat system. Moisture emission
from suboor cannot exceed 3 lbs. per 1,000
sq. ft. per 24 hours as measured with the
calcium chloride test in accordance with
ASTM F1869-04 or ASTM F2170 In-Situ
Relative Humidity not to exceed 75%.
• Turn the heat off for 24 hours before, during
and 24 hours after installation when installing
over radiant heated suboors. Failure to
turn the heat off may result in signicantly
shortened working time of the adhesive.
• Make sure that the temperature in the room is
at least 65°F (18°C) during installation.
• Floor temperature must not exceed 85°F
(30°C).
• Once the installation has been completed,
the heating system should be turned on and
increased gradually (5 degrees increments)
until returning to normal operating conditions.
• Refer to the radiant heat system’s
manufacturer recommendations for
additional guidance.
• Failure to strictly follow adhesive
manufacturer’s guidelines may result in
failure and void the warranty.
ELECTRIC HEATING MATS NOTICE
Electric heating mats that are not embedded
into the suboor are not recommended for use
