How Cold Is Too Cold?

If you still have unfinished repairs late in the fall, be aware of the temperature requirements for the materials you are using. As a rule, most products for exterior repairs need a minimum of 50° to cure properly.

For example, concrete needs a month to cure, while the water evaporates from within it. Once we have snow and freezing weather, that curing doesn’t occur at the proper rate, and the new concrete can crack and crumble. For that reason, try not to pour concrete less than 30 days before the first anticipated freeze. You should also pour concrete only on a day when the temperature is above 40°; if the overnight temperature will drop below 40°, cover the concrete with plastic and hay or straw to retain the heat created by the curing process.
