HOLE FILLER - SMALL GAPS/CRACKS

This expanding polyurethane foam is formulated for small gaps and cracks, with a controlled, minimal expansion that fills narrow voids neatly without over-expanding and distorting the surrounding work. Dispensed through a straw, it fills holes, cracks, gaps, and voids around windows, doors, pipes, outlets, and trim, forming an airtight, insulating seal that stops drafts, moisture, and pests. The low expansion makes it the right choice around finished openings where high-expansion foam would bow frames or ooze out. For precise sealing of small gaps, it is the controlled-expansion foam.

Key Features:

• Controlled Expansion -- Low expansion fills small gaps neatly without distortion.
• Airtight Seal -- Stops drafts, moisture, and pests at the gap.
• Straw Dispenser -- Fills around windows, doors, pipes, outlets, and trim.
• Finished-Opening Safe -- Won't bow frames or ooze like high-expansion foam.
• Insulating -- Seals and insulates narrow voids.

Where to Use:

• Small gaps -- Filling narrow cracks and voids precisely.
• Finished openings -- Sealing around windows, doors, and outlets safely.
• Air sealing -- Closing small drafts around penetrations.
