Nitoflor FC150 HP/SL - High Performance Epoxy Floor Coating

Overview

Nitoflor FC150 HP/SL is a heavy-duty, two-component epoxy floor coating system manufactured by Fosroc, specifically designed for demanding industrial and commercial flooring applications. This high-performance coating delivers exceptional durability, chemical resistance, and aesthetic versatility for environments requiring both protection and visual appeal.

Product Description

Nitoflor FC150 HP/SL is a self-smoothing epoxy resin system supplied in pre-tinted kits available in 8 litre and 16 litre sizes. The product utilizes base, hardener, and colour pot components that are common to both roll coat and self-levelling screed applications. The formulation produces a slightly textured gloss finish when applied as a roll coat, while creating a smooth, durable surface when applied as a self-levelling system.

Application Methods

The product offers two primary application methods:

• Roll Coat Application: Applied in two coats using brush or roller application methods, achieving an approximate total dry film thickness of 400-500 microns (200-250 microns per coat)
• Self-Levelling Screed: Applied at a nominal thickness of 2 to 4mm, providing a dense, impervious, seamless floor surface

Mixing Requirements

Proper mixing is critical for optimal performance:

• Method: Use a slow-speed mixer (350-500 rpm) fitted with a large spiral-type mixing attachment
• Procedure: Add colour pots to base component, mix for 1 minute; add hardener, mix for minimum 3 minutes
• Important: Mix in an efficient manner to ensure no colour pigment streaking; scrape vessel walls with a spatula
• Pot Life Extension: Pour product into flat trays rather than keeping in original container to extend working time

Substrate Requirements

Moisture and Environmental Conditions

• Substrate Moisture Content: Must be less than 5% (verified using Tramex CMEX11 moisture meter)
• Relative Humidity: Not greater than 75% at installation time
• Rising Damp: Should not be applied to surfaces known to suffer from or likely to suffer from rising damp
• Application Temperature: Both substrate and ambient temperature must be above 10°C
• Concrete Age: At least 28 days old for new water-reduced concrete

Surface Preparation

Essential for maximum adhesion:

• Remove all loose materials, old coatings, curing compounds, release agents, laitance, oil, and grease
• Achieve CSP profile of 2-3 using light grit blasting or grinding
• Remove dust and debris via vacuum cleaning
• For epoxy resin screeds: rub down high spots and trowel marks; light sanding may be applicable

Priming

• Apply 1-2 coats of Nitomortar 903 before Nitoflor FC150 HP/SL application
• Allow touch-dry between prime coats and 12-24 hours prior to main coating application
• On very porous concrete, additional third coat of Nitoflor FC150 HP/SL may be required

Primary Uses and Applications

Nitoflor FC150 HP/SL is designed for use in:

• Industrial Environments: Factories, manufacturing facilities, machine surrounds
• Food Industry: Kitchens, production areas, food processing plants

• Healthcare Facilities: Hospitals, clean rooms
• Educational Institutions: Schools requiring durable, hygienic flooring
• Retail & Commercial: High-traffic applications in supermarkets, prisons, film studios
• Specialist Uses: Laboratory floors, bunds, coves, and drains within production areas

Anti-Slip Enhancement Options

When enhanced slip resistance is required, the coating can be saturated with:

• Nitoflor Anti-Slip Grains 01: Coarse silica sand (#16/30) applied at 50-500g/m² for epoxy systems
• Nitoflor Anti-Slip Grains 02: Medium silica sand (#30/60) applied at 50-500g/m² for light to fully blinded effects
• Nitoflor Anti-Slip Grains 21: Applied to achieve varying slip resistance ratings

These grains are broadcast over wet coating and encapsulated with a second coat application, achieving P5 wet pendulum test ratings when properly applied.

Storage Conditions

• Temperature Range: 10°C to 30°C in original unopened packs
• Environment: Keep in dry storage conditions
• Shelf Life: Reduced at high temperatures
• Note: The new formulation is NOT compatible with previous base, hardener, or colour pot versions

Limitations and Restrictions

Nitoflor FC150 HP/SL should not be applied in the following circumstances:

• On surfaces suffering from rising damp or moisture content exceeding 5%
• To asphalt, weak or friable concrete, unmodified sand cement screeds, PVC tiles/sheets, or substantially moving substrates
• As an application over tiles
• In areas where significant thermal shock is likely to occur
• For exterior use where subject to sunlight or prolonged chlorinated water immersion
• Below 10°C substrate and ambient temperature

Colour Stability Considerations

• UV Sensitivity: Not UV stable; discolouration may occur even in internal environments including exposure through windows
• Chemical Staining: Some colours may darken or develop a brown tinge when exposed to sunlight or certain chemicals (more noticeable on white, light, and grey systems)
• Batch Consistency: Use only components with identical batch numbers in one application area to ensure uniform colour

Maintenance and Service Life

The service life can be considerably extended through good housekeeping practices:

• Regular cleaning using rotary scrubbing machines with water-miscible cleaning agents
• Temperature management up to 55°C service temperature
• In applications where long-term appearance is important, clear sealers or polishes may be necessary to protect the epoxy and provide renewable top coats

Safety and Environmental Information

• Solvent-Free Formulation: Reduces environmental impact and improves worker safety
• VOC Content: 14g/litre, meeting environmental standards
• Cleaning: Tools and equipment should be cleaned immediately after use with Fosroc Solvent 10; hardened material can only be removed mechanically
• Important: Do not add solvents to the mix; acetone, methylated spirits, and other solvents significantly affect curing and intercoat adhesion
