How to protect the floor from freezing in rainy and snowy weather

Sprinkle salt at every step of the corridor.

Salt water does not freeze, the composition of salt is potassium chloride, and the composition of snow is water. Potassium chloride is a very soluble chemical. Potassium chloride is dissolved in water to form potassium chloride aqueous solution, which contains potassium ions and chloride ions.

When anyone wants to freeze, when chloride ions and potassium ions exist, chloride ions and potassium ions will destroy the crystal network structure of water and make it impossible for water to freeze.

In other words, salt can prevent snow from freezing.

Usually, water freezes at zero degrees Celsius. When salt (or brine) is sprinkled on the surface of ice and snow, the ice and snow will melt into water by lowering the "freezing point". This is the basic principle of "salting" to melt ice and snow.
