Everbuild Expanding Foam Gun Grade 750ml

Product Overview

Everbuild Gun Grade Expanding Foam supplied in a 750ml canister is a professional polyurethane-based expanding foam designed for use with gun applicators. It expands up to 50 times its original volume, forming a dense, medium-fine cell structure that effectively fills, seals, and insulates cavities and gaps. 

The formulation cures rapidly, tack-free in around 8 minutes and ready for cutting or plastering within approximately one hour, offering an efficient, clean, and controllable application process.

This foam provides strong adhesion to a wide range of construction materials, including concrete, brick, plaster, timber, and metal, making it highly versatile across building and installation tasks. Its cured bead delivers long-term load-bearing stability after around 12 hours and remains resilient to both temperature fluctuation and moisture exposure.

It provides thermal conductivity of 0.04 W/mK and demonstrates excellent sound-deadening properties, improving both energy efficiency and acoustic insulation. Designed specifically for use with gun foam applicators, it delivers accurate dosing and reduced waste during application.

The cured foam withstands long-term temperature ranges between -40 °C and +80 °C, and short-term exposure up to +100 °C, ensuring stability and durability under varying environmental conditions. The 750ml can yields approximately 37 litres of expanded foam when fully cured.

Features & Benefits

• Quick Setting Time: Cures within approximately one hour, allowing the filled area to be cut, sawn, or plastered shortly after application.
• High Expansion Rate: Expands up to 50 times its can volume, enabling effective filling of wide or irregular cavities with minimal material use.
• Excellent Adhesion: Bonds securely to common building materials including wood, metal, brick, stone, and concrete, ensuring reliable structural support.
• Thermal and Acoustic Insulation: Provides a thermal conductivity of 0.04 W/mK and reduces sound transmission through filled voids and joints.
• Durable and Stable: Maintains full load-bearing performance after 12 hours and resists degradation across a broad temperature range from -40 °C to +100 °C (short-term).
• Controlled Application: Formulated for use with professional gun applicators, allowing precision control, reduced overspray, and cleaner results.
• Can Size – 750ml: Expands to approximately 37 litres of cured foam, suitable for extensive sealing and insulation work.

Applications

• Gap Filling: Ideal for sealing around pipe penetrations, window frames, door frames, and irregular masonry voids.
• Framework Fixing: Used to anchor door and window frames, timber structures, and thresholds securely in place.
• Pre-Plaster Preparation: Suitable for electrical chases and deep joints before the application of plaster or sealant.
• Thermal Insulation: Provides insulation behind exterior wall cladding, soffits, and barge boards to improve building efficiency.
• Acoustic Sealing: Reduces airborne sound through cavity walls and structural joints.

Installation Guidance

• Surface Preparation: Ensure all surfaces are clean, dry, and free from dust or debris. Lightly moisten surfaces with water to assist curing.
• Application Method: Shake the can vigorously about 20 times before use. Attach securely to the gun applicator, keeping the can inverted during dispensing.
• Filling Guidance: Only partially fill cavities; the foam will expand to fill remaining voids. Excess can be trimmed after curing.
• Cleaning: Clean nozzle and valve immediately after use with Everbuild Dual Purpose Foam Cleaner. Cured foam must be removed mechanically.
• Safety Precautions: Always wear protective gloves and eye protection. Do not pierce or burn the canister. Store and transport away from direct sunlight and heat sources.
