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.

Nitoseal SC100: Technical Specifications and Applications
Product Overview
Nitoseal SC100 is a neutral cure silicone sealant engineered for specialized sealing and detailing applications in construction. It serves multiple critical functions across waterproofing and surface preparation processes, particularly in facade and wall systems where precision and durability are essential.
Primary Applications
Nitoseal SC100 is utilized for several distinct purposes:
Screw and Nail Head Sealing: The product seals screw and nail heads during surface preparation, protecting them from moisture infiltration before membrane application.
Coving Detail Formation: Nitoseal SC100 forms coving details at right angle bends by applying a bead of the sealant to create rounded corners that provide structural integrity in waterproofing applications.
Static Crack Filling: The sealant fills static cracks up to 2mm wide, preparing surfaces for subsequent membrane application.
Fillet Creation: Nitoseal SC100 creates 12mm fillets at joints before membrane application, ensuring proper joint preparation and geometry.
Key Characteristics
Formulation
Nitoseal SC100 is a neutral cure silicone sealant, meaning it cures through a chemical process independent of moisture exposure, making it reliable in various humidity conditions. This formulation distinguishes it from moisture-cure systems and provides consistent performance characteristics.
Surface Compatibility
The product demonstrates excellent performance on multiple substrate materials commonly found in facade and construction applications, including concrete, masonry, and cladding materials.
Pre-Application Curing
When used for coving details and crack treatment, Nitoseal SC100 must be allowed to cure and form a protective skin before subsequent applications such as membrane installation. This pre-curing step is essential for achieving proper bond breaker functionality and preventing unwanted adhesion to substrate bases.
Application in Waterproofing Systems
Nitoseal SC100 plays an important preparatory role in waterproofing membrane systems. It is specifically mentioned as a pre-treatment material in systems such as Nitoproof 410, Nitoproof 310, and Nitoproof 810, where surface preparation is critical to membrane performance. The sealant ensures that screw heads and structural irregularities are sealed before the primary waterproofing membrane is applied, preventing water penetration through these potential weak points.
Surface Preparation Requirements
Before Nitoseal SC100 application, surfaces must be:
- Clean and free of contaminants
- Dry and sound
- Free from excessive movement
- Without protrusions that could compromise the seal
Integration with Bond Breaker Systems
When forming coving details, Nitoseal SC100 works in conjunction with polyethylene bond breaker tape. The sealant creates the initial rounded profile, and after curing, bond breaker tape is applied over it before the primary waterproofing membrane is installed. This system prevents the membrane from adhering to the joint base, allowing proper flexibility and movement accommodation.
