Hydrostatic Pressure
If the concrete slab is visibly wet, or experiencing hydrostatic pressure, the cause of the moisture should be properly
addressed prior to installation of oor covering. Consult Mohawk Group Technical Services at 800.833.6954
TEMPERATURE
The oor and room temperature must be acclimated by maintaining the temperature between 65°F and 85°F, and the humidity
between 30% and 65%, for at least 48 hours before and during installation. In addition, the carpet and adhesive should be
stored under these conditions for at least 24 hours before installation. The installation site must be acclimated with controlled
temperature and humidity.
When the installation is complete, the jobsite must be maintained at normal service temperature and humidity.
