In the cabinet world, a good base seal keeps the dirty outside outside and the clean inside controlled.
Outdoor telecom, utilities, traffic control, and LV distribution cabinets all face the same threat - environmental ingress. The cabinet base is the most common failure point. When it’s not sealed properly, you invite water, gas, dust, pests, roots, and corrosion, leading to downtime, call-outs, and expensive repairs.
Sealing the cabinet base is not optional — it's essential protection.
Why Cabinet Bases Must Be Sealed
A cabinet's base is the barrier between the environment and valuable electrical equipment. Without a proper seal, you risk:
• Water ingress – leading to damp electronics, corrosion, and insulation breakdown.
• Gas leakage – a potential hazard in utilities or gas network applications.
• Pests, weeds, and roots – physical obstruction and long-term damage to duct space.
• Dust and particulates – blocking filters and sensitive electronics.
• Thermal instability – condensation cycles that accelerate failures.
A properly sealed base keeps the dirty outside out and the clean inside controlled.
Traditional Cabinet Base Sealants
For years, the industry has relied on two-part pourable resins to fill and seal cabinet bases. While effective, they come with several limitations:
• Often contain hazardous isocyanates (MDI/HDI).
• Require mixing, with strict ratios and limited pot life.
• Single-use only – once mixed, you must pour it or waste it.
• Typically require dry surfaces for adhesion, which isn’t always realistic outdoors.
These resins have served their purpose, but the industry is shifting. Engineers now demand safer chemistry, easier handling, re-enterability, and performance in real-world UK weather.
Introducing GreenStuff: The Next Generation Cabinet Base Sealant
GreenStuff was developed to solve these problems.
It’s a new generation of cabinet base sealant: non-hazardous, one-component, reusable for up to one week once opened, and capable of bonding to damp bases.
Most importantly, it's 100% Made in Britain , ensuring local quality control, shorter lead times, and lower environmental impact.
Key Features
🚫 Non-hazardous: formulated without MDI or HDI — safer for installers, no special transport restrictions.
🟢 One-component: ready to pour straight from the container, no mixing required.
♻️ Reusable for up to one week: open, use, reseal — perfect for phased installations.
💧 Bonds to damp surfaces: no need to wait for the perfect dry base.
Benefits in Real-World Applications
• Safety & compliance: eliminates hazardous chemicals and simplifies COSHH requirements.
• Productivity: one-component format means no mixing errors and faster installs.
• Less waste: reusable for a week, ideal for multi-day or multi-cabinet rollouts.
• All-weather performance: adheres to damp or moist surfaces, reducing weather delays.
• Sustainability: locally made, reducing carbon miles and supporting the UK supply chain.
