HOLE FILLER - LG GAPS & CRACKS

This expanding polyurethane foam is formulated for large gaps and cracks, expanding generously as it cures to fill the bigger voids that a standard foam cannot bridge in one pass. Dispensed through a straw, the indoor/outdoor insulating foam forms an airtight, waterproof bond that seals out drafts, moisture, and pests around framing, large penetrations, and wide openings. Its high expansion fills more volume per bead, speeding work on big gaps while still curing to a rigid, trimmable seal. For sealing and insulating large openings around a building, it is the high-expansion choice.

Key Features:

• High Expansion -- Expands generously to fill large gaps and wide voids.
• Airtight & Waterproof -- Forms a bond that seals out drafts, water, and pests.
• Indoor/Outdoor -- Insulating foam for interior and exterior openings.
• Straw Dispenser -- Lays a controlled bead into big gaps and cracks.
• Rigid, Trimmable Cure -- Cures firm and trims flush for a finished seal.

Where to Use:

• Large gaps -- Filling wide openings a standard foam can't bridge.
• Framing & penetrations -- Sealing big voids around framing and large pipes.
• Air sealing -- Closing large drafts around the building envelope.
