ASTM E84 tested+
Cured FullStop foam was tested for surface flame spread.

Tested when cured+
Results apply to the tested cured foam sample and setup under controlled conditions. ASTM E84 measures surface burning; it is not a fire-resistance rating.

Where in my shed, exactly?+
Shed walls on clean, dry wood, metal, concrete or drywall. Open stud bays work best. Never foam a vented roof deck. Protect the floors and practice on cardboard first.
How many cans will my shed take?+
One can is rated for up to 20 sq ft at 1-inch thickness. A 12-can kit is rated for up to 240 sq ft at 1 inch, or 120 sq ft at 2 inches. 10x12 shed: about 3 kits at 1 inch. Add a 10% allowance, then round up to a full kit. Actual coverage varies with application; overhead work and first-time projects may need more.
Will my shed stay warmer?+
It seals the gaps where outside air leaks, and 90% of customers reported better temperature control. That number is customer-reported, not a promise. Results depend on your shed, your climate and how much you seal.
How are my kit savings calculated?+
Your kit discount is the difference between the crossed-out price and offer price, multiplied by your selected quantity. Free extras are separate from that comparison.
What warranty is included?+
The standard 1-year limited warranty applies automatically. FullStop foam is eligible for a free extension to 10 years when registered within 30 days of purchase. Accessory coverage and exclusions differ. Read the warranty terms.
