Rinse off your concrete
During the winter months in Minnesota, salt, or a de-icing chemical, is commonly used to clear snow and ice from paved surfaces. Salt has the potential to cause surface defects in all exterior concrete that is subjected to freeze/thaw conditions. Many times the salt is applied purposefully to keep sidewalks and driveways clear, however, salt may also be hitching a ride on your vehicle from the roadways. It is good practice to rinse all your concrete surfaces as soon as possible in the spring even if you didn’t purposefully apply salt to your concrete surfaces.
Having a routine sealing schedule for your concrete is similar to changing the oil in your car. Your car engine will not last very long if you do not change the oil regularly and, chances are, neither will your concrete.
