It totally depends on how you use it. 1 can will make about 2 gallons of foam. So basically, however you use it, when you use about 2 gallons of foam, it's done. This can is for a limited use situation. When you need a lot of foam, such as foaming entire walls, or an entire structure, you can buy several cans or you can purchase Premise 2 and also a foaming concentrate and a foaming spraying such as the Solo Foaming sprayer and make gallons and gallons of foam.
