Question: How much volume does this kit create
Answer: This kit creates a total of 8 cubic feet.
Question: Can I pour all at once or should I do it in batches?
Answer: I would do it in quart batches. It is tough to mix 2 gallons at once before some of it starts to cream.
Question: Does this foam adhere to the surface it is applied to?
Answer: It sticks to most things unless there is mold release, silicone, or oils used to keep it from bonding. Make sure to wear protective gear because it will stick to clothes, skin etc.
