Division 02 — Construction / Protective Coating

Protective Coatings

Protective coatings for concrete and steel are film-forming systems — epoxy, acrylic, polyurethane, or bituminous — applied to act as a controlled-permeability barrier against the specific chemical and physical agents that cause deterioration: carbonation, chloride ingress, chemical attack, and corrosion.

CFC Egypt manufactures a comprehensive protective coating range at our Sadat City plant, covering the full spectrum of concrete and steel protection requirements for Egyptian infrastructure and industry. Our epoxy coating series (EGYPOX 1175 grades) provide chemical-resistant linings for tanks, sumps, and process structures. EGYCRYL EX is an exterior anti-carbonation acrylic coating for facades and exposed concrete, while EGYCRYL FR is a fire-retardant acrylic emulsion paint for interior use. EGYPRO epoxy and zinc-rich primers protect structural steelwork from corrosion in marine, industrial, and urban environments. EGYTAR coal-tar epoxy systems handle below-grade and immersed steel, and the siloxane-based EGYROCK water-repellents impregnate concrete and masonry. From thin-film facade finishes to thick solvent-free epoxy linings for chemical containment, we supply the system for the exposure.

01

What It Covers

Protective coating chemistry spans five technology families. Each is matched to a specific substrate (concrete or steel), exposure condition, and performance requirement — the correct system selection is the most critical decision in achieving a long service life.

01

Epoxy Protective Coatings & Linings

Solvent-free and solvent-borne epoxy coatings (EGYPOX 1175, EGYPOX 1175 SG) for chemical-resistant lining of concrete tanks, sumps, bunds, and channels, and for protective coating of structural steel in aggressive environments. Solvent-free grades are specified for immersed service and for enclosed spaces where solvent ventilation is impractical. The SG (self-generating) variant produces a gloss finish suitable for surfaces requiring both chemical protection and cleanability.

02

Acrylic Coatings & Paints

EGYCRYL EX is an anti-carbonation acrylic emulsion paint for exterior use, applied to concrete facades, bridge soffits, and exposed columns to retard carbonation and chloride ingress while resisting weathering and UV. EGYCRYL FR is a fire-retardant acrylic emulsion paint for interior use, characterised by resistance to bacteria and fungi — suitable for interior walls and ceilings where a fire-retardant, hygienic finish is required.

03

Steel Anti-Corrosion Systems

Multi-coat systems for structural steelwork comprising zinc-rich primers (EGYPRO ZN 1K, EGYPRO ZN 2K) for galvanic protection of blast-cleaned steel, epoxy intermediate coats (EGYPRO 11 PR, EGYPRO 211 PR, EGYPRO 221) for barrier protection and intercoat adhesion, and UV-stable polyurethane or acrylic topcoats for atmospheric exposure. Bituminous epoxy systems (EGYTAR EP1, EGYTAR EP2) are used for buried and immersed steelwork — piles, tanks, and pipeline coatings — where UV resistance is not required but high film build and chemical resistance are.

04

Polyurethane Topcoats

Two-component aliphatic polyurethane coatings (EGYCOAT PU) provide the best UV stability of any protective topcoat in CFC Egypt's range, retaining colour and gloss under prolonged direct sunlight without chalking or yellowing. They are applied as the final coat over epoxy primer and intermediate systems on structural steelwork, concrete facades, and car park decks where a durable, aesthetically maintained finish is required throughout a long maintenance interval.

05

Transparent Water-Repellents & Sealers

EGYROCK S and EGYROCK W are ready-to-use, siloxane-based transparent impregnating water-repellents (penetrating sealers) for external concrete and masonry — EGYROCK S is solvent-based and EGYROCK W is water-based. They impregnate the surface to give high water-repellence and long-term protection without forming a visible film or altering the appearance. EGYSEALER is a water-based acrylic sealer undercoat for surfaces requiring a sealing base coat. These treatments significantly reduce water absorption while retaining the natural appearance of the substrate.

02

Where It's Used

Protective coatings are applied wherever the ambient environment, process chemistry, or service conditions would cause unacceptable deterioration of unprotected concrete or steel within the design service life of the structure.

Chemical Plants & Industrial Facilities

Chemical containment bunds, process sumps, effluent channels, and concrete floor areas in chemical manufacturing are exposed to the widest range of aggressive agents: concentrated acids and alkalis, organic solvents, oxidising agents, and repeated thermal cycling from process upsets. Solvent-free epoxy linings applied at 500–1000 microns DFT over blast-cleaned concrete provide a continuous barrier that resists chemical permeation and the mechanical damage from cleaning operations. System selection must match the specific chemicals handled — CFC Egypt's technical team provides chemical resistance data for the EGYPOX range.

Water & Wastewater Treatment

Clarifiers, aeration tanks, digesters, and effluent channels in water and wastewater treatment plants present a demanding combination of exposure conditions: continuous wet service, biogenic sulfuric acid attack in anaerobic zones, abrasion from solids, and the requirement for food-grade or potable-water-contact compliance in drinking water treatment. Solvent-free epoxy coatings and specialist chemical-resistant linings from CFC Egypt's protective coating range are formulated to perform in these conditions while complying with relevant water quality standards.

Building Facades & Architectural Concrete

Exposed concrete facades in Egypt's urban environment are subject to air pollution, high UV levels, and the thermal stresses of high diurnal temperature swings that cause surface crazing and accelerate carbonation. Elastomeric acrylic anti-carbonation coatings (EGYCRYL EX) extend the carbonation-free service life of the concrete cover while maintaining an aesthetically acceptable facade finish. For existing buildings where surface cracking has already occurred, the crack-bridging capability of elastomeric grades is particularly important in preventing accelerated deterioration at crack locations.

Structural Steelwork & Industrial Buildings

Portal frame industrial buildings, steel-framed warehouses, and bridges in Egypt's coastal and delta environments are exposed to elevated humidity, industrial pollution, and in coastal zones, direct chloride deposition that accelerates steel corrosion. A correctly specified protective coating system — zinc primer, epoxy intermediate, polyurethane topcoat — can achieve a maintenance-free service life of 15 years or more in moderate industrial environments, significantly reducing the lifetime cost of corrosion management for structural steelwork.

Marine & Port Structures

Jetty piles, quay aprons, lock gates, and port infrastructure in marine environments face the most aggressive corrosion conditions — the splash and tidal zone combination of continuous wetting and drying, UV, and high chloride concentration accelerates deterioration of both steel and concrete faster than any other atmospheric exposure category. Below-water and buried steel is protected with coal-tar epoxy systems (EGYTAR EP1, EGYTAR EP2); above-water steel with a three-coat zinc/epoxy/PU system; and concrete with high-build epoxy or elastomeric anti-carbonation coatings.

Frequently Asked Questions

Technical and commercial questions on protective coatings answered plainly. For a specific application or product recommendation, contact our technical team.

A protective coating is a film-forming material applied to a concrete or steel surface to act as a controlled-permeability barrier against the specific agents that cause deterioration: carbonation, chloride ingress, chemical attack, and corrosion. For concrete, the dominant threats are carbonation (CO₂ penetration lowering pH and initiating rebar corrosion), chloride ingress, and chemical attack from acids and sulfates. For steel, the primary threat is oxidation driven by moisture, oxygen, and chloride. The coating system is chosen based on the specific threat, the substrate condition, and the service environment: epoxy for chemical resistance, acrylic or PU for UV-stable facade protection, zinc-rich primers for steel anti-corrosion, and tar-epoxy for immersed or buried conditions.

An anti-carbonation coating is an elastomeric or rigid film applied to exposed concrete facades, columns, and soffits to block the diffusion of atmospheric CO₂ into the concrete matrix. Carbonation occurs when CO₂ reacts with calcium hydroxide in the cement paste, lowering the concrete pH from approximately 12.5 to below 9 — the point at which the passive oxide layer protecting reinforcing steel breaks down and active corrosion begins. Anti-carbonation coatings are rated by their CO₂ diffusion resistance (Sd value); values above 50 m are considered effective for standard atmospheric exposure. Elastomeric grades that bridge hairline cracks are preferred because carbonation often progresses through cracks faster than through sound concrete.

A thick-film epoxy lining (typically 300–1000 microns DFT) should be used when the concrete or steel surface is in direct contact with liquids or chemicals that would penetrate a thin decorative coating. Typical applications are: chemical containment bunds and sumps in contact with acids, alkalis, or solvents; the interior of water tanks where a continuous, pinhole-free membrane is needed; effluent channels and wet wells in wastewater treatment; and below-grade concrete in contact with chemically aggressive groundwater. The lining must be selected for chemical resistance to the specific agent — no single epoxy is resistant to all chemicals — and applied at controlled film thickness with holiday testing after curing.

Zinc-rich primers protect steel by galvanic action: zinc particles in the coating are anodic relative to iron, so when moisture reaches the primer film, the zinc corrodes sacrificially in preference to the steel substrate. This cathodic protection continues as long as sufficient zinc is in contact with the steel surface and a conductive electrolyte (moisture) is present. Zinc-rich primers are specified for structural steelwork in corrosive environments — marine, industrial, and buried service — applied directly to blast-cleaned steel (Sa 2.5). CFC Egypt's EGYPRO ZN 1K (single-component, moisture-cure) and EGYPRO ZN 2K (two-component epoxy) cover ambient-temperature application and shop-applied primer scenarios respectively.

CFC Egypt's protective coating range includes: epoxy linings (EGYPOX 1175, EGYPOX 1175 SG) for chemical and immersed service; an exterior anti-carbonation acrylic coating (EGYCRYL EX) and an interior fire-retardant acrylic emulsion paint with antibacterial and antifungal resistance (EGYCRYL FR); polyurethane topcoats (EGYCOAT PU) for UV-stable outdoor finishes; zinc-rich primers (EGYPRO ZN 1K, EGYPRO ZN 2K) for steel anti-corrosion; epoxy primers and intermediate coats (EGYPRO 11 PR, EGYPRO 211 PR, EGYPRO 221); coal-tar epoxy coatings (EGYTAR EP1, EGYTAR EP2) for below-grade and immersed steel; siloxane-based transparent water-repellents (EGYROCK S solvent-based, EGYROCK W water-based) for impregnating concrete and masonry; and EGYSEALER acrylic sealer undercoat. All products are manufactured at our Sadat City facility.
