Abrasion resistant coating | Heavy duty | Concrete compatible | High build epoxy systems

System Overview

For concrete floors and sand and cement screeds requiring durable surface protection, epoxy systems provide a dense, chemically resistant coating film. Epoxy floor paints for concrete floors are specified across warehouses, factories, workshops and garages where abrasion resistance and oil tolerance are critical.

The EVEREST Everflor epoxy range includes solvent-free, water-based and solvent-based technologies, allowing specification from light refurbishment through to heavy duty industrial flooring. All systems are two pack materials requiring accurate mixing and controlled application conditions to achieve full performance.

Water-based epoxy systems offer lower odour application and thinner film builds suited to moderate duty environments. Solvent-free epoxy systems deliver higher build, thicker protective films designed for heavy traffic and more demanding service conditions. Solvent-based epoxies provide strong adhesion and practical application characteristics where ventilation is available.

Suitable Substrates & Surface Preparation

Concrete must be structurally sound, fully cured and free from laitance, oil contamination and curing compounds. Mechanical preparation such as grinding or shot blasting is typically required to provide a suitable surface profile for epoxy adhesion. Acid etching alone is rarely sufficient for heavy duty applications.

Moisture content must be assessed prior to coating. Epoxy systems form relatively impermeable films and are not suitable for substrates affected by rising damp without installation of an appropriate epoxy damp proof membrane. Excess moisture can result in blistering or debonding.

Sand and cement screeds should be firmly bonded and of adequate strength. Weak or friable screeds must be repaired or replaced before coating.

Previously painted floors may be overcoated where existing coatings are sound and compatible. Abrasion to create a mechanical key and thorough degreasing are required. Failing coatings must be removed to ensure long-term adhesion.

Mixing ratios, pot life and recoat windows must be strictly followed. Inaccurate mixing or overextended pot life will compromise cure and chemical resistance.

Performance Characteristics & Limitations

Solvent-free epoxy systems provide high build, abrasion resistant finishes suitable for heavy traffic, pallet trucks and forklift use when correctly specified. Their dense cross-linked structure offers strong resistance to oils, fuels and many industrial chemicals.

Water-based epoxy coatings deliver good adhesion and moderate chemical resistance with reduced odour, making them appropriate for occupied buildings and refurbishment projects. Film thickness is generally lower than solvent-free systems, limiting their suitability for heavy mechanical loading.

Solvent-based epoxy systems offer strong substrate penetration and practical flow characteristics but require adequate ventilation during application.

Epoxy coatings form rigid films and may not tolerate significant substrate movement or structural cracking. UV exposure can cause ambering or surface chalking in some formulations, particularly in external environments, although this does not always reduce protective performance.

These systems are not suitable for contaminated, weak or poorly prepared substrates. Long-term performance is directly linked to preparation quality and environmental control during installation.

Internal vs External Considerations

Epoxy floor paints are primarily specified for internal environments. Temperature and humidity significantly influence cure speed and intercoat adhesion. Low temperatures extend cure times, while high humidity can affect surface finish.

In external applications, UV stability must be considered. Standard epoxy systems may discolour under prolonged sunlight exposure. Where colour retention is critical externally, alternative topcoats may be required.

Slip resistance can be adjusted through incorporation of graded aggregates within the epoxy system, particularly in wet process areas or access routes.

Selection Guidance & When to Specify Alternatives

For light commercial or refurbishment projects, water-based epoxy systems provide a balanced combination of durability and practical installation. As traffic intensity and chemical exposure increase, specification should move toward higher build solvent-free epoxy systems to achieve increased thickness and enhanced durability.

Where flexibility and enhanced UV stability are priorities, polyurethane floor systems may provide advantages over standard epoxy coatings.

For environments with severe chemical attack or bunded containment requirements, specialist high build epoxy systems beyond general-purpose formulations should be specified.

System selection should be based on traffic type, chemical exposure profile, substrate condition and required service life, with preparation and moisture control forming the foundation of performance.
