Product Details

ABRO® PU Foam Insulation Sealant – Multi-Purpose Expanding Foam (750ml)

ABRO® PU Foam is a high-performance, one-part polyurethane expanding foam designed to create a professional-grade seal for insulation and filling needs. This 750ml canister is engineered to expand significantly upon application, filling deep gaps, cracks, and cavities that traditional sealants cannot reach.

It cures into a rigid, off-white structure that provides excellent thermal insulation and acoustic soundproofing, making it a staple for construction, HVAC, and home renovation projects.

Key Features

  • High Expansion Rate: Effectively fills large, irregular cavities and voids with ease.

  • Superior Insulation: Provides a high thermal and acoustic barrier, helping to reduce energy costs and dampen noise.

  • Strong Adhesion: Bonds to almost all common construction materials, including brick, concrete, plaster, wood, metal, and various plastics.

  • Weatherproof & Airtight: Creates a durable seal against drafts, moisture, pests, and dust.

  • Mold & Moisture Resistant: Once cured, the foam is resistant to rot and water absorption, ensuring long-term structural integrity.

  • Easy to Finish: Once fully cured, the foam can be easily cut, sanded, plastered, or painted to match the surrounding surface.

Common Applications

  • Door & Window Installation: Filling and insulating the gaps between frames and walls for a draft-free finish.

  • Pipe Penetrations: Sealing around plumbing, HVAC vents, and electrical conduits passing through walls or floors.

  • Roofing & Attics: Sealing gaps in roof tiles, eaves, and attic partitions to improve climate control.

  • Wall Cracks: Filling deep structural cracks or voids in masonry and drywall.

Usage Instructions

  1. Preparation: Shake the can vigorously for at least 60 seconds before use. Ensure the surface is clean and slightly moistened with water to speed up the expansion and curing process.

  2. Application: Turn the can upside down and attach the applicator straw. Fill the cavity only about 40% to 50% full, as the foam will expand significantly.

  3. Curing: Avoid touching the foam while it is tacky. Allow it to harden completely before trimming.

  4. Finishing: Cut away excess foam with a sharp knife. For outdoor use, the foam must be painted or coated to protect it from UV degradation.

Safety Tip: Always wear gloves and safety goggles during application. Use in a well-ventilated area, as the foam is highly adhesive and difficult to remove from skin and clothes once cured.
