How much do you save per can when you buy FastCoat spray foam in bulk?
You save more per can as the FastCoat pack gets bigger: a single can costs $21.59, while each can in the 48-can pack costs $12.28. The table lists the current price of every cans-only pack of FastCoat insulation spray foam, the price per can and the price per board foot, the unit spray foam coverage is measured in.
One board foot is 1 square foot of foam 1 inch thick, and each FastCoat can yields up to 20 board feet. Every row on this page shows its price per unit the same way, so you can compare pack sizes of any product before you add one to the cart.
How many cans of spray foam do you need?
To work out how many cans of spray foam you need, multiply the area in square feet by the thickness in inches and divide by 20, the board feet one FastCoat can covers at 1 inch. Add about 10% for overspray, rough surfaces and cold days, because lower temperatures reduce yield.
A 2-inch (5 cm) layer of FastCoat reaches about R‑11.3 at R‑5.66 per inch. Our guide on how thick spray foam insulation needs to be covers other R-value targets.
Three common DIY jobs, worked out at 2 inches thick:
- Basement rim joists in a 30 x 40 ft (9 x 12 m) house: 140 linear feet of 2x10 rim joist is about 108 sq ft, or 216 board feet. That comes to about 12 cans with the margin, so the 12-can pack covers it.
- Floor of a 12 x 16 ft (3.7 x 4.9 m) cabin or tiny house: 192 sq ft is 384 board feet, or about 21 cans with the margin, so the 24-can pack fits.
- Walls of an 8 x 10 ft (2.4 x 3 m) shed with 8 ft walls: 288 sq ft of wall, less a 3 x 7 ft door, leaves 267 sq ft, or 534 board feet. That is about 30 cans with the margin, so plan on the 36-can pack.
Should you buy cans only or a kit with a foam gun?
You should buy a kit if you don't own a foam gun yet, and cans only if you do. FastCoat sprays through a foam gun fitted with one of the two tips packed with every can, Tip A for walls and Tip B for ceilings.
Every FastCoat kit adds a Kraken Bond foam gun, at least 1 can of foam gun cleaner and a PPE kit, and each kit row lists what comes in the box. Clean the gun with foam cleaner after each session to keep it ready for the next case, since cured foam can only be removed mechanically. For rim joists, cathedral ceilings and other hard-to-reach spots, the 24 in. (61 cm) and 40 in. (102 cm) long-nozzle guns extend your reach.
How do you store bulk spray foam until you use it?
Store bulk spray foam in its original cans, out of direct sunlight and away from anything hotter than 122°F (50°C), and use FastCoat within its 18-month shelf life. Before you spray, bring each can to about 68°F (20°C) for at least 24 hours; the ideal can temperature is 41°F to 86°F (5°C to 30°C).
Buying the pack that matches your project, plus the 10% margin, keeps every can inside that shelf life. The answers below cover shipping, returns and when a contractor order makes more sense.
