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!
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.
