Fosroc Nitoflor EU5

Product Overview

Nitoflor EU5 is a high-strength self-smoothing epoxy underlay consisting of special resins and graded aggregates formulated to withstand chemical attack and impact loads. Supplied as a three-component system: resin base, resin hardener and fillers. When correctly laid, it provides a surface ready to receive applications of other Fosroc flooring systems such as Nitoflor FC140, FC150 and SL2000 epoxy toppings and coatings. Bond strength exceeds the tensile strength of concrete.

Features

• Cost effective — economical floor levelling solution
• High strength — high compressive, tensile and flexural strength
• Quick and easy to lay — self-smoothing properties for efficient application
• Seamless — forms a continuous jointless underlay
• Durable — withstands chemical attack and impact loads
• Zero water absorption — nil water absorption (per manufacturer)
• Excellent adhesion — bond strength exceeds concrete tensile strength

Applications

• Floor levelling prior to epoxy topping installation
• Substrate preparation before polyurethane floor coatings
• Industrial floor renovation underlay preparation
• Epoxy levelling of uneven concrete floors

Application Guidelines

• Surface preparation — substrate must be sound, clean and dry; new concrete must cure at least twenty-one days
• Laitance removal — remove laitance on new concrete by grit blasting, scabbling or grinding
• Oil contamination — old floors require mechanical cleaning or chemical degreaser to remove oil
• Priming — generally not required on sound, untreated dry concrete
• Mixing — add hardener to base and mix until homogeneous, then slowly add fillers while mixing
• Application — spread to uniform thickness with squeegee or notched trowel; use spiked roller to eliminate air
• Overcoating time — allow specified curing time before applying topcoat
• Expansion joints — existing expansion joints must be carried through EU5 and subsequent toppings

Packaging

15 litre pack (three-component system)

Notes

• Substrate moisture content must not be excessive; no rising damp
• Must be applied within pot life after mixing; unused material must be discarded
• Avoid skin and eye contact with epoxy resin — wear gloves and eye protection
• Ensure adequate ventilation in the working area
• Clean tools immediately with suitable solvent
• Shelf life: twelve months in original unopened packs (per manufacturer)
• For detailed application methods, coverage rates and technical parameters, refer to the official product data sheet

FAQ

How does EU5 differ from epoxy floor toppings?

EU5 is a self-smoothing epoxy underlay used to level uneven concrete floors and provide a smooth base for subsequent epoxy toppings (such as Nitoflor FC140, FC150) or self-levelling epoxy finishes (such as SL2000). EU5 is not a final wearing surface — it must be overcoated with the specified floor topping.

What thickness can be applied?

EU5 is designed for application in the range of one point five to five millimetres. For greater thicknesses, other products in the Nitoflor EU range are available. Contact us via WhatsApp for specific recommendations.
