Will re-salting help? Heres the situation: its lightly raining in the upper 20's and things that were icy this morning are still basically icy. I applied rock salt this morning and the roads and parking lots are wet and slushy. Temps. will be in the low to mid 20's through tomorrow morning. Will re-salting wet pavement prevent refreezing later when the temps fall again? Will the salt from earlier (7:00am) work tonight without re-salting? Will I have ro re-salt tomorrow morning? I don't want to do more than is necessary. Please advise.
