Deliver materials to project site in original sealed containers with
manufacturer's name and brand clearly identified. Store in dry locations
with adequate ventilation and handle in a manner to prevent damage or
1.6
ENVIRONMENTAL CONDITIONS
Enclose or protect surfaces to be treated from excessive temperature
changes. Ambient temperature shall be above 10 degrees C 50 degrees F
during application and for duration of curing period. Keep water level
below location of surfaces being treated until completion of the treatment
and curing period. Provide adequate ventilation to properly oxidize
metallic waterproofing.
