SPECIAL CONSIDERATIONS

Radiant Heat:

1. RI flooring can be installed over Radiant heating (hydroponic) systems.

There must be at least 1/2 inch of separation between the radiant

heat source and the RI flooring. The maximum temperature of the

subfloor surface must not exceed 85°. Before installing flooring

products over newly constructed radiant-heating systems, operate the

system at maximum capacity to force any residual moisture from the

cementitious topping of the radiant-heating system. Then set the

thermostat to a comfortable room temperature for the installation. For

existing systems, the system must be switched off for a minimum of

48 hours before, during and 48 hours after flooring installation. This is

the only type of radiant heat that is approved. Subfloors should have

been operational for at least 3 weeks prior to installation to drive out

moisture and calibrate temperature settings. All radiant heat floors

should be turned down so subfloor temperature is maintained at 65

degrees for 3 days prior to installation and kept at 65 degrees for at

least 48 hours after installation to allow the adhesive to fully cure.

Maximum operating temperature should never exceed 85°F.

2. Direct Sunlight: Installations in areas where there is heavy direct

sunlight exposure for long periods of time should utilize window

treatments.

3. Protecting New Installations: New Installations must be protected while

the adhesive cures. Early foot traffic, point or rolling loads can cause

adhesive displacement or breaking of the bond between the adhesive

and the tile or substrate
