Gorilla Heavy Duty Expanding Foam 340ml

Gorilla Heavy-Duty Expanding Foam is a versatile, fast-curing polyurethane foam designed for professional-strength filling, sealing, and insulating. Supplied in a 353ml can with a precision straw applicator, it expands to create a durable barrier against air, moisture, and pests. This multi-purpose foam is perfect for a wide range of applications including sealing around windows and doors, filling gaps in attics, crawlspaces, masonry, plumbing, vents, ceilings, and walls. It bonds securely to common construction materials such as wood, metal, concrete, brick, PVC, plastic, and plaster. The foam expands to fill cracks and gaps effectively without excessive overflow, ensuring a neat and professional finish. Use it both indoors and outdoors to improve energy efficiency by eliminating drafts. For best results, shake the can well before use, apply using the straw, and allow to cure completely. Once hardened, any excess foam can be easily trimmed or sanded for a perfect result.
