PROTECTION

**************************************************************************************
Select appropriate statements for installation – floor, wall or both.  Delete non-applicable statements.
**************************************************************************************

[Protect floors from general traffic for at least 72 hours after installation.  Plywood or stepping boards may be used after 24 hours when occasional stepping on the floor is unavoidable.]

[Protect walls from impact, vibration and heavy hammering on adjacent and opposite walls for at least 14 days after installation.]

Protect from freezing and total water immersion for at least 21 days after installation.

**************************************************************************************
When dealing with cement-based products, it should be noted that temperature and humidity during and after installation of tile affect final curing time, i.e., low temperatures (60 degrees and under) and high humidity (70% and above) will delay final cure time.
