RE: GBlist: cold, durisol, and surface bonding

["J. F. Straube" <jfstraube@uwaterloo.ca>]

Surface bonding requires weather above 40 F for at least 24 hours,
prefereably more.
Most insulated concrete forms can have concrete filled in colder weather.  I
have seen Durisol walls built in very cold weather, -20 Celsius, with no
extra measures taken.

Shane-  Personally, without tenting I would not do any exterior masonry work
unless the temp stays above freezing overnight.  If the water freezes before
the cement is cured that long, it is worthless.  At least, that's the rule
of thumb here in VT.
