Nitoseal SC100 - Silicone Joint Sealant for Facade Applications
Nitoseal SC100 is a one part, gun applied, neutral cure silicone sealant which cures rapidly to form a durable, weathertight seal. Features outstanding weathering performance, remains permanently flexible across a wide range of service temperatures (-50°C to +150°C), and ensures no staining of porous building materials. Suitable for sealing moving or static joints in facade applications such as precast or in-situ concrete, curtain walls, lightweight cladding and tilt-up slabs. High joint movement accommodation up to 80% (+50%/-30%). Available in Concrete Grey and Black.

Product Intelligence
Nitoseal SC100 - Silicone Joint Sealant Technical Details and Specifications
Product Overview
Nitoseal SC100 is a neutral cure silicone sealant manufactured by Fosroc, designed for specialized waterproofing and detailing applications in construction. This product serves multiple critical functions in building facade and structural systems.
Primary Applications
Nitoseal SC100 is specifically engineered for the following uses:
- Sealing screw and nail heads during surface preparation for waterproofing membrane application
- Forming coving details at right angle bends to provide structural integrity in waterproofing applications
- Filling static cracks up to 2mm wide before membrane application
- Forming 12mm fillets at joints before membrane application
Key Characteristics
Sealant Type
- Neutral cure silicone formulation
- Designed to cure independently of environmental humidity and moisture conditions
- Suitable for both internal and external applications
Technical Properties
As a neutral cure silicone, Nitoseal SC100 offers:
- Flexibility for accommodating minor substrate movement
- Durability in weathering and exposure conditions
- Non-acidic formulation reducing potential damage to sensitive substrates compared to acetoxy-cure silicones
Typical Construction Detailing Methods
Coving Details at Right Angle Bends
Nitoseal SC100 can be applied as a bead to form rounded corners (coving details) at structural junctions. The sealant must be allowed to cure fully before general application of waterproofing membranes. This technique is commonly used in:
- Wall-to-wall joints
- Wall-to-floor transitions
- Other structural angle connections
Crack Preparation and Sealing
For static cracks up to 2mm in width, the sealant is applied as a pre-treatment before membrane installation. The material must skin over and develop initial cure before subsequent waterproofing applications are applied.
Application in Waterproofing Systems
Nitoseal SC100 plays an integral role in comprehensive waterproofing systems including:
- Nitoproof 310 - Fibre enhanced water-based latex membrane for wet areas
- Nitoproof 410 - Fast drying polymer modified cementitious membrane
- Nitoproof 810 - Water-based latex membrane for wet area applications
In these systems, Nitoseal SC100 is used during the surface preparation phase to seal fastener heads and prepare joints before the primary waterproofing membrane is applied.
Alternative Products
For specific applications where Nitoseal SC100 may not be suitable, Fosroc offers alternative neutral cure silicone options:
- Selleys Wet Area Silicone - An alternative neutral cure silicone for similar applications in waterproofing systems
Storage and Handling
As a silicone-based product, Nitoseal SC100 should be stored in accordance with manufacturer recommendations to maintain product integrity and performance characteristics prior to application.
Quality Assurance
Nitoseal SC100 is manufactured by Fosroc, an international manufacturer and supplier of specialized construction products. Fosroc maintains technical support resources and provides comprehensive documentation including Safety Data Sheets (SDS) and Technical Data Sheets (TDS) for all products.
