Product Intelligence
Nitoflor Sicaltop: Silicon Carbide Floor Hardener Technical Details
Product Overview
Nitoflor Sicaltop is a factory-blended powder floor hardener designed to provide durable, hard-wearing surfaces on concrete floors. The product is composed of silicon carbide and alumina-based aggregates, Portland cement, and special additives, creating a monolithic bond with the base concrete when applied by the shake-on method to freshly laid concrete slabs.
Key Features and Advantages
Durability and Wear Resistance
Nitoflor Sicaltop delivers exceptional durability characteristics that significantly exceed standard concrete floors. The product provides:
- Greater than 200% improvement in abrasion resistance compared to untreated concrete floors across the recommended dosage range, as demonstrated by testing performed by the Australian Mineral Development Laboratories
- Extremely strong, hard-wearing, and impact-resistant surface suitable for the heaviest traffic conditions
- Non-metallic, chemically inert aggregate that does not rust
Slip Resistance Properties
The silicon carbide content provides outstanding non-slip characteristics:
- Maximum slip resistance that increases with use as the concrete surface wears
- Slip resistance remains effective when wet, making it suitable for demanding environments
- Provides a pleasant black speckling and glittering sparkle on the finished surface
Environmental and Health Considerations
- RCS (Respirable Crystalline Silica) Hazard Free – classified as not hazardous for RCS in accordance with Australian Inventory of Industrial Chemicals, containing less than 0.1% RCS
- Non-staining aggregate
- Chemically resistant composition

Compressive Strength
Tests to BS 1881 Part 4-1970 indicate that Nitoflor Sicaltop achieves a compressive strength of approximately 95 MPa at 28 days.
Water Permeability
Simulated permeability tests under pressures of up to 340 kPa demonstrated a significant reduction in water permeation, providing enhanced protection against moisture ingress.
Application Details
Suitable Applications
Nitoflor Sicaltop is ideally suited for industrial areas subject to the heaviest traffic, including:
- Loading bays and trucking lanes
- Car parks and warehouse floors
- Repair workshops and machine shops
- Fire escapes, stairways, and entrances
- Loading ramps and machine surrounds
- Manufacturing facility floors
Application Method
The product is applied by the shake-on method to freshly laid concrete slabs:
- After floating the surface, but before the concrete has stiffened excessively, sprinkle Nitoflor Sicaltop by hand
- Allow grains to sift through fingers for uniform distribution
- Tamp grains flush with the surface using a steel trowel
- Close over the surface by steel trowel finishing
- Texture the surface using a steel trowel on the flat to produce the slip-resistant finish
- Apply a suitable curing compound or keep damp with wet hessian
Application Rates and Coverage
| Traffic Conditions | Dosage (kg/m²) | Coverage (m² per 20kg bag) |
|---|---|---|
| Light traffic | 2.0 | 10.0 |
| Medium traffic | 3.0 | 6.7 |
| Heavy traffic | 4.0 | 5.0 |
Note: Coverage figures are theoretical; practical coverage may be reduced due to wastage factors and substrate variations.
Supply and Storage
Product Supply
- Nitoflor Sicaltop Grey 20kg: Product code FC602040-20KG
- Available in natural concrete grey color
Storage Requirements
- Shelf life: 18 months if stored in original, undamaged packaging
