Nitoflor Anti-Slip Grains 31: Technical Details, Specifications, and Features

Product Overview

Nitoflor Anti-Slip Grains 31 is a high-performance silicon carbide-based floor hardener designed for finishing concrete floors to provide exceptional slip and wear resistance while maintaining a smooth surface finish. This product represents a specialized solution for creating durable, safety-focused flooring systems in demanding industrial and commercial environments.

Material Composition

The product is manufactured from high-purity, chemically treated silicon carbide grains that have been specially ground and milled to achieve specific shape and screen grading characteristics. The composition ensures thorough bonding with Portland Cement concrete surface mixes.

Chemical Analysis

• Silicon Carbide Content: >92% by weight
• Aggregate Type: Virgin silicon carbide, graded and acid-washed
• Overall Composition: Chemically treated, high-purity silicon carbide grains

Key Physical Properties

Hardness and Durability

• Hardness (Modified Mohs Scale): 13 (extremely hard)
• Knoop Hardness: 2480 Knoop 100
• Crystallography: Alpha-type crystal structure
• Color: Black with aesthetic glittering sparkle finish

Grain Specifications

• Grain Shape: Angular (designed to resist breaking under traffic conditions)
• Nominal Sizing: 0.5 mm to 1.4 mm (with ±5% maximum tolerance variation)
• Grading: Factory-graded and acid-washed for consistency

Performance Advantages

Slip and Wear Resistance

Nitoflor Anti-Slip Grains 31 deliver maximum slip resistance compared to many other floor hardener aggregates. A distinctive advantage is that slip resistance increases with wear of the concrete floor, as the cement surface surrounding the grains wears away, progressively exposing more of the hard silicon carbide particles.

Chemical and Environmental Resistance

• Non-staining properties ensure the floor maintains its aesthetic appearance
• Chemically resistant formulation suitable for various industrial environments
• Non-rusting composition as it is non-metallic

Installation and Application Benefits

• Applied at time of concrete placement (monolithic application)
• Grains are shaped to resist detachment from the cement surface under traffic conditions
• Gives an aesthetically pleasing surface finish with pleasant black speckling and glittering sparkle

Application Specifications

Application Method

Nitoflor Anti-Slip Grains 31 are applied as a single dry shake application to compacted, screeded, and floated concrete bases. The product can be applied using either:

• Monolithic method: Applied directly to newly placed concrete
• Topping method: Applied to concrete screeds

Application Rate

• Minimum Application Rate: 0.5 kg/m²
• Method: Hand application, allowing grains to sift through fingers for uniform distribution
• Timing: Applied after floating but before concrete has stiffened excessively

Installation Process

1. Sprinkle grains by hand onto floated concrete surface
2. Tamp grains flush with surface using steel trowel
3. Close over surface with steel trowel finishing to seal holes and pits
4. Create texture using steel trowel on flat to produce slip-resistant finish
5. Apply suitable curing compound or keep damp with wet hessian

Suitable Applications

Nitoflor Anti-Slip Grains 31 are suitable for use in diverse settings including:

• Educational institutions: Schools and universities
• Healthcare facilities: Hospitals
• Public buildings and commercial spaces
• Industrial facilities: Factories and manufacturing plants
• Safety-critical areas: Fire escapes, stairways, entrances, loading ramps, machine surrounds

Compatibility with Epoxy Systems

Nitoflor Anti-Slip Grains 31 are also suitable for use in high build epoxy roll coat floor coatings such as Nitoflor FC150 HP, where they provide maximum slip resistance in resinous flooring applications.

Storage and Handling

• Storage Conditions: Store in dry conditions in original packaging
• Shelf Life: Maintain product integrity in original, unopened packs
• Environmental Control: Protect from moisture exposure

Product Supply

• Packaging Size: 20 kg bags
• Product Code: FC605180-20KG
• Coverage: 0.5 kg/m² (theoretical coverage; practical figures reduced due to wastage factors and substrate variations)

Important Safety and Regulatory Information

A Safety Data Sheet (SDS) is available from Fosroc and should be carefully reviewed prior to use. In emergency situations, contact any Poisons Information Centre (phone 13 11 26 within Australia) or a medical professional for advice. Application and performance data may change from time to time, so current documentation should always be consulted.
