RedStuff Intumescent Water & Gas Tight Duct Sealant: Superior Fire Resistance for Critical Sealing Applications

RedStuff Intumescent Sealant is a high-performance, single-component caulk and mastic sealant designed using innovative FyBrid technology. It delivers excellent thermal insulation and robust sealing against water, gas, smoke, and fire. Ideal for ducted networks, cable penetrations, and building services, RedStuff provides reliable protection for walls, floors, and ceilings in challenging environments.

This neutral curing system, part of the trusted AC Cable Solutions range, ensures non-hazardous, flexible, and durable sealing for various industrial and commercial applications.

Key Features of RedStuff Intumescent Sealant

  • FyBrid Technology: Advanced technology enhances performance with superior fire resistance and durability.

  • Water & Gas Tight: Reliable protection tested up to 2.0 bar pressure for critical sealing needs.

  • Thermal Insulation: Forms a porous char when exposed to fire, sealing off ducts and service penetrations.

  • Non-Hazardous, Flexible Composition: Neutral curing, single-component sealant ensures safe application and flexibility.

  • UV and Chemical Resistance: Resists harmful chemicals, including methane and chlorine gas, and protects against UV exposure.

  • Versatile Applications: Ideal for cable ducts, service penetrations, door frames, and joints in walls, floors, and ceilings.

  • Non-Adiabatic: Low Cable De-Rating: With a 20mm thickness, the thermal resistance of 5.1 K/W effectively disperses heat, reducing the risk of overheating and maintaining the cable's full current capacity for consistent and reliable performance.

Applications of RedStuff Intumescent Sealant

The RedStuff Intumescent Sealant is suitable for a wide range of applications, including:

  • Sealing cable ducts, pipes, and service penetrations

  • Providing fire and smoke resistance (when used with DuctSeal FR)

  • Protecting against water, gas, and chemical ingress

  • Ensuring safe sealing around door frames, joints, and voids

  • Sealing damp surfaces in walls, floors, and ceilings

How to Use RedStuff Intumescent Sealant

  1. Preparation: Clean the surface to remove dirt, grease, and debris. Lightly abrade if necessary.

  2. Application: Use a caulking gun to apply RedStuff directly to the surface. For optimal results, work from the bottom up to ensure complete coverage.

  3. Finishing: Smooth the sealant using a damp sponge for a clean finish.

  4. Cleaning: Remove uncured material with a solvent-based wipe.

Health & Safety

  • RedStuff is non-hazardous and free from MEKO, ensuring user safety during application.

  • Use tools cautiously for re-entry and removal, especially when cables are de-energised.

Storage Instructions

Store in a cool, dry environment away from direct sunlight. Once opened, use within 1 month if securely capped. Shelf life is 12 months for unopened products.

Re-Entry & Removal

The cured sealant forms a rubber-like material, allowing easy re-entry with sharp tools. This flexibility makes it suitable for installations that may require adjustments over time.

Installation

Cure Time

Grey Stuff will cure 3-4mm daily, depending on the Humidity and temperature. The higher the humidity %, and temperature, the quicker RedStuff will cure. A minimum requirement of 20mm RedStuff is required for an effective seal.


Cleaning

Uncured material spillages can be cleaned with a solvent-based wipe.

Health & Safety

RedStuff is based on a neutral curing system that is hazardous-free to protect users when carrying out tasks like sealing cable ducts. Non-hazardous Zero MEKO.

Re-entry & Removal

RedStuff will cure to a similar hardness of a rubber eraser, so re-entry and removal are achievable. The ease of this depends on the type of tools used. For example, a sharper tool will be easier than a blunt-ended tool. Only use sharp tools when cables are de-energised. AC Cable Solutions accepts no responsibility for damaged cables.

Cable Suitability

RedStuff is a single-component neutral curing system containing no solvents. Our formulation does not damage the properties of a cable sheath or stain surfaces.


Storage

RedStuff should be kept in a cool, dry environment and away from sunlight. Product shelf life is 12 months. Once opened, any remaining product can still be used for 1 month afterwards, provided the screwcap is securely fitted.
