GreenStuff Cabinet Base Sealant, No Mdi, Reusable, Made-in-Britain Solution

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 easier handling, re-enterability, and performance in real-world UK weather.
