You have the right to expect your exterior concrete to serve you well for many years. It will, if you practice these tips in caring for your concrete driveways, sidewalks, patio, and garage floor. If possible, it is best to practice these tips for the entire life of the concrete. However, if it is not possible, we recommend following them at least for the first two winters.
- Completely remove snow from the pavement.
- Do not leave any snow on the pavement or pile snow on it. If it is partially covered with snow and partially bare to the open air, there is a good chance that cracking will occur along this boundary.
- Do not use de-icers on any concrete surfaces during its first year of service. Please use plain, clean sand whenever increased skid resistance or traction is needed.
- Never use de-icers containing ammonium sulfate or ammonium nitrate. They will rapidly disintegrate concrete causing surface scaling. Lawn and garden fertilizers may also contain ammonium sulfate or ammonium nitrate. Always sweep fertilizer from concrete surfaces before washing thoroughly.
- Street snow removal efforts often incorporate the use of de-icers containing salts. Snow clinging to the underside of cars and snow plowed onto driveways may contain de-icers. Care should be taken to remove these de-icers to avoid damage to your concrete surfaces. It is best to keep concrete clear of snow and de-icers whenever possible.
