GreenStuff – Re-enterable, Non-Hazardous Cabinet Base Sealing System

Non-Hazardous & Safe to Use
Free from harmful isocyanates, GreenStuff can be handled without complex COSHH constraints, making it installer-friendly and safer for all environments.

One-Component, No Mixing Required
Ready to use straight from the container— no measurement errors or equipment are needed. Pour and let it seal.

Self-Levelling & Gap-Filling
GreenStuff flows and levels to fill voids and irregularities, ensuring a continuous, sealed barrier beneath the cabinet base.

Re-enterable for Future Maintenance
Unlike many permanent resins, GreenStuff can be cut, removed, and re-sealed— ideal for upgrades, additional services, or cable changes.

Bonds to Damp Substrates
Performs reliably even on slightly wet surfaces, eliminating the need for perfect dryness before application.

Long-Term Environmental Protection
Blocks ingress of water, dust, pests, weeds, roots, and gases— safeguarding internal equipment and extending lifecycle.

Virgin-Approved Option
A dedicated Virgin Media–approved variant is available to meet network operator compliance and specification requirements.

Resin-Only Variant Available
For projects where backing materials or kit components are not needed, GreenStuff is offered in a resin-only form.

Made in Britain
Manufactured under UK standards, supporting local supply chains and ensuring high quality control.

• LV distribution cabinets
• Public lighting cabinets
• Feeder pillars
• Traffic control cabinets
• Outdoor transformer stations
• Telecom cabinets
• Any installation requiring pest/weed prevention and climate control

• Skin time: Up to 2 hours depending on conditions (surface may remain tacky for 48 hours).

  Contents
  1 × 2.5 L container of GreenStuff resin
  
  3 × circular foam disks (included when bought as a kit; 2.5 L containers also sold individually)
  
  1 × pair of nitrile gloves
  
  Site Preparation
  Can be poured directly onto fairly dry concrete—no sand required.
  
  If standing water is present: sprinkle cement to absorb moisture and form a crust before pouring.
  
  If the concrete is completely dry: no additional cement or sand is needed.
  
  Direct-Buried Applications
  For direct-buried installations, float GreenStuff over the ducts.
  
  Ensure the foam flange is properly fitted before application.

What is GreenStuff used for?
GreenStuff is primarily used as a cabinet base sealant: sealing the base of outdoor telecom cabinets, feeder pillars, transformer enclosures, LV distribution boxes, street lighting control cabinets, traffic control cabinets, etc. It prevents ingress of water, pests, dust, gas, and roots.

Is GreenStuff hazardous?
No. GreenStuff is formulated to be free from harmful isocyanates, making it safer for installers and simpler in terms of health & safety protocols.

Can GreenStuff be used on damp surfaces?
Yes. GreenStuff is designed to bond to slightly damp substrates. It still performs in UK climate conditions where perfect dryness is not feasible.

Is GreenStuff re-enterable?
Yes. One of its key strengths is that it remains cuttable and removable for future access - making maintenance, additions, or reworks possible without destroying the seal.

How long can it remain open once opened?
Provided the container is properly resealed, GreenStuff can remain usable for up to 1 week for multi-day installations.

What is the difference between GreenStuff and RedStuff /
GreyStuff?
GreenStuff is a cabinet base resin sealant, distinct from the duct sealing compounds RedStuff and GreyStuff. While those are designed for sealing cables and ducts, GreenStuff is formulated for base sealing in cabinets and enclosures. The chemistry is tailored for flow, adhesion, re-entry, and durability in that context.

Can I get a Virgin-approved version?
Yes. A Virgin-approved variant is offered to meet network operator standards and compatibility requirements.

How long does GreenStuff take to fully cure?
Under favorable conditions, surface skin forms in a few hours. Full cure (internal depth) may take up to 20 days, depending on temperature, humidity, and volume.
