What are the main types of wall putty?

Wall putty is classified into two types: lime putty and cement putty. Lime putty is commonly found in older homes and is primarily made of limestone. Cement putty, on the other hand, is made of Portland cement and sand. Cement-based putty is more common than lime putty. It has a longer shelf life and dries faster than lime putty. While both types can be used on interior walls, cement putty is more commonly used on exterior walls.
