Expanding Foam – Exact Gap – Indoor & Outdoor Use

Product Overview

Our Professional Exact Gap Expanding Foam in a 500ml can is engineered for minimal expansion, ensuring controlled gap filling where precision is essential. This polyurethane foam is designed to provide a fine, stable bead with low post-expansion, reducing the need for excessive trimming and minimizing material waste. The hand-held format allows easy, direct application without the need for specialist equipment, making it ideal for both domestic and professional installation tasks.

Once cured, the foam offers excellent adhesion, insulation, and structural stability across a wide range of substrates, maintaining its dimensional integrity even in confined spaces. Its controlled expansion prevents surface stress or distortion on sensitive materials, ensuring a clean, reliable finish every time.

Features & Benefits

• Minimal expansion formulation: Ensures precise application with minimal waste and reduced trimming.
• Controlled bead stability: Minimizes risk of foam sagging or dripping.
• Quick curing performance: Tack-free in 4–8 minutes and cuttable within 9–12 minutes.
• High adhesion strength: Bonds securely to masonry, timber, and plastics.
• Durable cured structure: Offers medium-fine cell structure with temperature resistance from -40°C to +80°C.
• Re-usable valve system: Prevents clogging or leakage, allowing reuse of partially discharged cans.
• Transport-safe design: Safe storage and transport in both horizontal and vertical positions.
• Temperature and storage stability: Optimal performance between 5°C and 30°C; storage between 20°C and 25°C.
• Can volume – 500ml: Suitable for precise hand-held applications.

Applications

• Roof tile voids and draught points: Seals openings to prevent heat loss.
• Pipe and service penetrations: Fills gaps around pipework to maintain airtightness.
• Door and window frames: Provides foam support without stressing materials.
• Electrical chases and wall voids: Fills gaps for a smooth surface before plastering.
• Wall and floorboard gaps: Enhances insulation between structural joints.
• Behind exterior cladding or soffit boards: Acts as an insulating filler.
