Overview

HandiFoam E84 II-15 is a disposable, low-pressure, two-component closed-cell spray polyurethane foam kit built for small jobs where you need fast fill, strong adhesion, and a tight seal. For fence post work, it’s ideal for sealing and insulating around post sleeves, brackets, and penetrations through siding or slabs, and for stabilizing light-duty posts where your design and local code allow. The formulation conforms to ASTM E84 Class 1 (A) at 2″ thickness and delivers approximately R-6.6 per inch (initial) when applied correctly.

Key Features

• Compact 15 board-foot kit for quick repairs, touch-ups, and small post-related sealing jobs
• Closed-cell foam structure for durable fill and reduced air movement
• Tack-free in roughly 30–60 seconds for faster job pacing
• Controlled, low-pressure spray for better placement in tight areas
• HFO-based chemistry designed to meet current environmental regulations
• 24-month shelf life when stored and handled properly

Included Items

• A-side and B-side disposable cylinders (two-component system)
• Handi-gun style dispensing unit with hose assembly
• Disposable mixing/spray nozzles (varies by kit packaging)

Applications / Use Cases

• Fence post foam kit positioning: seal gaps around post sleeves and brackets at walls, slabs, and decks
• Stabilize light-duty fence, mailbox, and sign posts where acceptable by design/code (not a structural concrete replacement)
• Fill voids in oversized penetrations and irregular gaps around posts and anchors
• Air-seal and insulate around exterior penetrations to reduce drafts and moisture movement
