Discover the DAP Barrier Foam Orange Polyurethane Foam Multipurpose Barrier Foam in a 23 oz can—a ready-to-use solution engineered to seal, insulate, and block air, moisture, and heat. The vivid orange can helps you see exactly where you’ve applied the foam, reducing gaps and gaps in your project. Built for both indoor and outdoor use, this paintable foam delivers reliable performance across a variety of applications—from new construction to renovation and remodeling.
Why this barrier foam stands out
-
Fire and high heat resistant: Designed to help slow the spread of flame and withstand elevated temperatures where a robust barrier is needed.
-
Moisture and mildew resistant: Formulated to hold up in damp environments, helping protect gaps and cracks from moisture-related damage.
-
Paintable finish: Easy to blend with surrounding surfaces once cured, so your project looks seamless.
-
Indoor and outdoor versatility: Suitable for a range of locations, from living spaces to exterior sealing around openings.
-
Easy cleanup with mechanical abrasion: Any excess can be trimmed or sanded after curing for a clean, professional finish.
-
Multipurpose coverage: Provides substantial seal in gaps, cracks, and fireblock applications with a coverage area of 870 (per can).
Ideal applications
- Gaps and cracks around windows and doors to improve insulation and reduce drafts
- Fireblock installations to help create safer, code-conscious barriers between wall cavities
- All-purpose sealing in areas prone to moisture, such as basements, crawl spaces, and bathrooms
- Around electrical and plumbing penetrations where a solid, paintable seal is beneficial
How it works and what to expect
This polyurethane foam expands to fill irregular spaces, creating a durable seal that resists moisture and mildew while maintaining structural stability. It remains paintable after curing, so you can finish the surface to match surrounding walls or trim. Since the foam is not permanently flexible, it cures into a solid barrier that holds its shape over time. Cleanup is straightforward with mechanical abrasion if you need to trim excess material or refine the edges after it sets.
