GreenStuff Cabinet Base Sealant | Safer, Reusable & Made in Britain

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.

Traditional Polyurethane Installations!

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.

  • Made in Britain: supporting UK manufacturing and consistent supply.

  • Virgin Media Approved: Fully tested and approved for use on all Virgin Media Cabinets 

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.
