Everbuild Expanding Foam Gun Grade 750ml

Description

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.
