Need to calculate for a different container size? Use the formula: (Container volume in cubic feet ÷ 0.35) × 1.35 = approximate number of 16 oz cans.
If you are filling multiple drums for flotation or insulation, individual cans are often the most expensive route. A small two-component spray foam kit how many cans of spray foam will fill a 55 gallon drum
A standard 55-gallon drum (typically used for oil or chemicals) has an internal volume of exactly 55 US gallons. However, drums are not always perfectly square inside; they have curved lids and recessed rolling hoops. For the sake of this calculation, we will assume you want to fill the main cylindrical body to the brim. Need to calculate for a different container size
Wait a minute. That number seems surprisingly low. If a single 16oz can yields 160 board feet, that implies one single can could fill almost two 55-gallon drums. A small two-component spray foam kit A standard
| Can size | Approximate cured foam yield | |----------|------------------------------| | Small (12 oz) | ~0.25–0.3 ft³ | | Large (24–30 oz) | ~0.6–0.7 ft³ |
Waste: Expect some overflow or "skinning" that needs to be trimmed. Always buy 10-15% more than your math suggests. The Cost-Effective Alternative: Two-Part Kits
