Do you salt before or after it snows? This is a question that many homeowners and city officials ponder when preparing for winter storms. The answer to this question can have significant implications for safety, efficiency, and cost-effectiveness. In this article, we will explore the advantages and disadvantages of salting before and after snowfall, and provide some expert advice on the best practices for maintaining safe and accessible roads and sidewalks during the winter months.
Salting before snowfall is often considered the most effective method for preventing ice formation. By applying salt to surfaces before the snow starts to fall, you can create a barrier that will melt the snow as it accumulates, reducing the amount of ice that forms. This approach is particularly beneficial in areas with heavy snowfall or where temperatures remain below freezing for extended periods. However, there are some drawbacks to consider. For one, salting before snowfall can be time-consuming and labor-intensive, especially for homeowners with large properties. Additionally, if the snow starts to fall before the salt is applied, the salt may not be as effective in preventing ice formation.
On the other hand, waiting until after the snow has fallen to salt can be a more practical approach for some. This method is less time-consuming and requires less effort, as you can simply spread the salt on the snow-covered surfaces once the storm has passed. However, there are risks associated with this approach as well. Salting after the snow has fallen can be less effective in melting the snow, especially if the temperature is already below freezing. This can lead to slippery conditions that pose a greater risk of accidents and injuries.
According to experts, the best practice is to use a combination of both methods. By applying a light layer of salt before the snow starts to fall, you can create a barrier that will help prevent ice formation. Then, once the snow has accumulated, you can apply additional salt to melt the snow and prevent ice from forming. This approach ensures that you are prepared for any amount of snowfall and can maintain safe and accessible surfaces throughout the winter.
When choosing the right type of salt for your needs, it is important to consider the environmental impact. Rock salt (sodium chloride) is the most common type of salt used for deicing, but it can be harmful to vegetation and aquatic life. Alternative salts, such as magnesium chloride and calcium chloride, are less harmful to the environment but may be more expensive. It is also important to follow the manufacturer’s instructions for proper application rates and to store the salt in a dry, cool place to prevent it from clumping.
In conclusion, the question of whether to salt before or after it snows is not straightforward. The best approach is to use a combination of both methods and to choose the right type of salt for your needs. By taking these precautions, you can ensure that your property remains safe and accessible throughout the winter months.
